Basics of
GERMS
1
What are
GERMS? Microbes that cause diseases are called germs They are tiny organisms – almost invisible without a microscope! And yet they are abundant on Earth.
They live in every nook and cranny in air, soil, rock, and water. Some survive happily in heat, while others thrive in freezing cold.
There are good germs and bad germs. The bad germs cause disease in humans, plants, and animals. Good germs are essential for a healthy life.
Since the 19th century, we have known that germs cause infectious diseases. Near the end of the 20th century, researchers began to learn that germs also contribute to many chronic diseases and illnesses.
Some scientific events and advances
Approximately 300 B.C. Aristotle, Greek philosopher and scientist, studied and wrote about living organisms.
1675 Antony van Leeuwenhoek discovered bacteria.
1796 Edward Jenner laid the foundation for developing vaccines.
1848 IgnĂĄc FĂźlĂśp Semmelweis discovered that simple hand washing could prevent passage of infection from one patient to another.
1857 Louis Pasteur introduced the germ theory of disease.
1867 Joseph Lister showed evidence that germs caused disease and pioneered the use of antiseptics during surgery to kill germs.
1876 Robert Koch, by studying anthrax, showed the role of bacteria in disease.
1928 Alexander Fleming was credited with discovering penicillin.
Different types of germs are as follows: Bacteria, Virus, Fungi, Protozoa
Different types of
Germs BACTERIA Bacteria are small. Made up of one cell, they look like tiny balls, rods or spirals under a microscope. They are essential as living on Earth would not be a possible without them. They are versatile and adaptable – surviving in both extreme heat and cold. Less than 1 percent of bacteria cause diseases in humans.

Strep throat is a bacterial infection caused by streptococcal (strep) bacteria in the throat and the tonsils. The throat gets irritated and inflamed, causing a sudden, severe sore throat.
Good Bacteria
The helpful bacterial vaccines:
Harmless anaerobic bacteria, such as Lactobacilli acidophilus, live in our intestines, where they help digest food, destroy diseasecausing germs, fight cancer cells, and give the body needed vitamins. Healthy food products, such as yogurt, sauerkraut, and cheese, are made using bacteria.
In some cases bacteria can be helpful. Several vaccines that keep us from getting sick are made from bacterial toxins. For example, one type of pertussis vaccine, which protects infants and children from pertussis (whooping cough), contains toxins from Bordetella Pertussis bacteria. This vaccine is safe and effective and causes fewer reactions than other types of pertussis vaccines.
Bad Bacteria
Some bacteria, however, are harmful. They produce toxins which can make us sick. Botulism, a severe form of food poisoning, affects the nerves and is caused by toxins from Clostridium botulinum bacteria.
Bacterial infections/ diseases Diarrheal diseases, Meningitis, Pneumonia, Sinusitis, Skin
diseases, Strep throat, Tuberculosis, Urinary tract infection and Vaginal infection
VIRUS
Viruses are amongst the smallest germs, smaller than even bacteria!
Virus are not cells
Virus consist of one or more molecules of DNA or RNA, which contain the virus genes surrounded by a protein coat. They can be rod-shaped, sphere-shaped, or multisided and some look like tadpoles. Most viruses survive by taking over the machinery that makes a cell work. Once inside the cell, viral molecules such as DNA or RNA direct the cell to make new virus offspring and multiply as a result.
Viruses do cause diseases Unlike most bacteria, most viruses cause disease because they invade living, normal cells, such as those in your body. Once inside the cells, they multiply and produce other viruses like themselves. Each virus is very particular about which cell it attacks.
Various human viruses specifically attack particular cells in your body’s organs, systems, or tissues, such as the liver, respiratory system or blood.
The good and the bad viruses:
Many viral infections do not result in diseases. For example, by the time most people in the United States become adults, they have been infected by cytomegalovirus (CMV). Most people infected with CMV, however, do not develop CMV-disease symptoms. Other viral infections can result in deadly diseases such as AIDS or Ebola hemorrhagic fever.

varicella-zoster virus, a type of
Herpesvirus. This virus also causes Chickenpox.
Viral infections/ diseases
Common cold, Diarrheal diseases, Flu, Genital herpes, Meningitis,
Pneumonia, Shingles and Skin diseases
FUNGI
A fungus is actually a primitive plant and can be found in air, in soil, on plants, and in water. Millions of different types of fungi exist on Earth. Some live in the human body, usually without causing illness.
Did you know? Mushrooms, yeast, mold, and mildew are the most common types of Fungi.
Fungi have actually
made our lives better. Penicillin and other
antibiotics, which can kill harmful bacteria in our bodies, are made from
fungi. Other fungi, such
as certain yeasts, are also
helpful. For example, when a warm liquid, such as water, and a food source, such as
sugar, are added to certain
yeasts, the fungus ferments.
The process of fermentation is essential for making
healthy foods like some breads and cheeses.

Mycoses Fungal diseases are called mycoses.
Mycoses can affect your skin, nails, body hair, internal organs such as
your lungs, and body systems such as your nervous system. Aspergillus fumigatus fungi, for example, can
cause Aspergillosis, a lung disease.
Fungal infections/ diseases
Athlete’s foot, Pneumonia, Sinusitis,
Skin diseases and Vaginal infection
PROTOZOA Protozoa are a group of microscopic one-celled animals. Protozoa can be parasites or predators. In humans, protozoa usually cause disease.
What diseases they cause?
Malaria is caused by a protozoan parasite. Another protozoan parasite, Toxoplasma gondii, causes toxoplasmosis, or toxo, in humans. This is an especially troublesome infection in pregnant women because of its effects on the fetus, and in people with HIV/AIDS or other disorders of the immune system.
Some protozoa, like plankton, serve as food for marine animals. Protozoa are found on land in decaying matter and in soil, but they must have a moist environment to survive. Termites wouldn’t be able to do such a good job of digesting wood without these micro organisms in their guts.
Infections/ diseases caused by protozoa Diarrheal diseases ,Skin diseases, Vaginal infection
Used cat’s litter may contain
Toxoplasma Gondii, a disease-causing parasite that can pass from a mother to her unborn child.
What are Gram-Positive & Gram-Negative bacteria? The nature of the cell wall determines the classification of bacteria as either Grampositive or Gram-negative, as determined by the Gram stain.
GRAM-POSITIVE BACTERIA
The cell wall of GramPositive bacteria is made up of two layers - Cell wall and Cytoplasmic membrane
The cell wall is a thick multi-layer of Peptidoglycan (a mixture of sugars and amino acids)
Lipoteichoic acids
Cell wall (Peptidoglycan) Cell membrane (Lipid bilayer)
Gram-Negative BACTERIA
The cell wall of Gram-Negative bacteria is made up of three layers - Outer membrane, Cell wall, and Cytoplasmic membrane
Outer membrane
Cell wall (Peptidoglycan) Cell membrane (Lipid bilayer)
The cell wall is thin and surrounded by an outer membrane (made up of Lipopolysaccharides and Lipoprotein)

Polymerase
Enveloped Virus
Besides the two components of Non-Enveloped Virus, this virus has an additional layer surrounding the Caspid, called the envelope (eg: Herpes Simplex, HIV and Flu) Polymerase
Envelope
TRANSMISSION OF GERMS Transmission is the passing of a communicable disease from an infected host individual or group to a conspecific individual or group, regardless of whether the other individual was previously infected. How germs make us sick? Germs can transmit to a person through one or more of the following means :
Germs can travel through air
You can transmit germs to another person through the air by coughing or sneezing. These are common ways to get viruses
that cause colds or flu or the bacteria that cause tuberculosis (TB).
Close contact can pass germs to another person
Scientists have identified more than 500 types of bacteria that live in our mouths. One way you can transmit oral bacteria is by kissing. Germs such as HIV, Herpes
simplex virus type 2, which causes Genital
Herpes, and Neisseria gonorrhoeae bacteria, which causes Gonorrhea, are examples of
germs that you can pass to another person through sexual intercourse.
You can pick up and spread germs by touching infectious material
A common way for some germs to enter the body is through unintentionally
passing feces from hand to mouth. It also is possible to pick up cold viruses from
shaking someone’s hand or from touching
contaminated surfaces, such as a doorknob or computer keyboard.
A healthy person can carry germs and pass them to others A small number of people, called carriers, get better after having typhoid fever, but continue to be infected by Salmonella
typhi bacteria (bacteria causing typhoid).
You can get typhoid fever if you eat food or drink liquids that have been prepared by someone who has typhoid fever or who is infected with S. typhi.
Indirect transmission can also make you sick Transmission can also be indirect, via another organism, either
a vector (e.g. a mosquito) or an
intermediate host (e.g. tapeworm in pigs can be transmitted to humans who ingest improperly cooked pork).

What are EVOLVED
GERMS?
Evolved germs give rise to emerging and re emerging infections
Emerging infections can be caused by: Previously undetected or unknown infectious agents.
EMERGING INFECTION These are the disease which were previously unknown or known whose rate of infecting humans have significantly increased in the past two years.
Known agents that have spread to new geographic locations or new populations Previously known agents whose role in specific diseases has previously gone unrecognized.
Re-emerging infections can be caused by:
RE-EMERGING INFECTION These are the disease which were previously unknown or known whose rate of infecting humans have significantly increased in the past two years.
Evolution of pathogens over time. Acquired resistance of pathogens to antimicrobial medications.

CRE - Carpabenam resistant enterobacteriace ( E.coli & K.pnuemoniae) are a growing threat in hospital settings with high probability of spreading to communities too.
CARBAPENEMS are considered as “last resort� antibiotics
10 Only 2 new antibacterial agents have been discovered during the past 4 years.
What are the signs of
germs evolving? Emergence of drug resistant strains:
Misuse of antibiotics, usage of antibiotics in the fields of Agriculture and Veterinary fields are major contributory factors of bacterial strains acquiring drug resistance.
There is an increased danger due to spread of drug resistant bacteria in community settings.
Drug resistance can develop against one or many types of antibiotics. Almost all common human pathogens like E.coli, K.pneumoniae, S.aureus, S.pneumoniae have acquired drug resistant genes system.
This is primarily a major concern in bacteria, but drug resistant H1N1 strains have also been discovered Infections caused by drug resistant bacteria are major cause of hospital acquired infections.
What are the signs of
germs evolving? The drug resistant germs – A global threat
Drug-resistant bacterial infections cause considerable mortality & morbidity. For instance, In 2005, almost 95000 people acquired methicillin-resistant Staphylococcus aureus (MRSA) infections in USA out of which 19000 people died due to the same.
According to the Centers for Disease Control and Prevention (CDCP), approximately 4% of hospitals in the nation have seen at least one case involving the super germ.

What are the signs of
germs evolving? New germs originating from non-human hosts
Avian Flu (H7N9, H5N1) & Swine Flu (H1N1, H3N2) are examples of infections where viruses have evolved to infect humans as new hosts.
With mutation at each stage, the virus/ bacteria can acquire capability to become contagious and spread from human to human. pathogen.
Types H7, H5 infections are entirely novel to humans. Novel MER Co V (Middle eastern SARS like Corona Virus) is believed to have originated from gene reservoirs of bats.
This phenomenon is not limited to viruses but also seen with bacteria strains. S.suis, E.coli O154 are examples where the bacteria commonly found in pigs/ cattle is now a human

There have been several out breaks of mumps in vaccinated population in Europe and US. Countries with re-established virus transmission or reporting imported wild poliovirus Countries endemic for wild poliovirus
Polio infected countries for which WHO reccommends Polio Immunization or boosting to travellers
Outbreaks are believed to be caused by multiple factors: inadequate levels of vaccination, primary or secondary vaccine failure, antigenic differences between the outbreak and vaccine strains, increased risk of transmission associated with college campuses, inherent limitations in mumps protective immunity, and misdiagnosis of infection.

Antimicrobial resistance Definition and mechanism What is Antimicrobial resistance? Antimicrobial resistance is the ability of germs to grow in the presence of a chemical (drug) that would normally kill it or limit its growth.
Gram-negative bacteria, such as E.coli, A.baumanni, P.aeruginosa, K.pneumonia, and Enterobacter sp., are dangerous group of disease causing germs because they are difficult to treat and have become increasingly resistant to currently available antimicrobial drugs.
In recent years, antimicrobial resistance has become an increasingly important health issue.
Definition and mechanism 1
Non-resistant bacteria exist
2
Bacteria multiply by the billions A few of these bacteria will mutate
MUTATION IN DNA
3 Some mutations make the bacterium drug resistant In the presence of drugs, only drug resistant bacteria survive
4
Drug resistant bacteria multiply and thrive
Examples of Antimicrobial resistance Micro organisms MRSA
Threat Causes minor infections of the skin to wound infections, bacteremia, and necrotizing pneumonia MRSA is highly endemic in hospitals with mean prevalence rates of >50% and as high as 70-80% Study has revealed that approx 50% of all S.aureus isolates are MRSA
MDR S.pneumoniae
This germ is the predominant pathogen involved in bacterial infections and remains the leading cause of community-acquired respiratory infections in children S. pneumoniae can result in bacteremia, meningitis, pericarditis, arthritis, and empyema; collectively these are referred to as invasive pneumococcal disease (IPD) [8] which can lead to severe illness, prolonged hospital stay and deaths
E.Coli ESBL producers
Such bacteria are associated with severe infections such as bacteraemias, intra-abdominal infection, urinary tract infections (particularly in the community setting) In China, the incidence of ESBL production from E. coli isolates ranged from 13%–15%

Entirely new germs like SARS virus (originated in China in 2003), Bird Flu (originated in China in 2005), MERS CoV (Middle East respiratory syndrome, Saudi Arabia, 2012) have caused epidemics with high mortality rates.
Humans have naive immunity to these novel strains making the threat more pronounced.
Genetic re-assortment among avian, human and/or swine influenza virus gene segments has occurred in pigs and some novel reassortant swine viruses have been transmitted to humans(H5N1, H7N9 etc).
The responsible strains are novel due to re assortment of several viral strains or transfer from animal reservoirs with mutations to affect Humans.
TYpes of novel strains
AVIAN INFLUENZA A(H7N9) VIRUS A new avian influenza A (H7N9) virus was first reported in China by the World Health Organization on April 1, 2013. Most of the reported cases of human infection have resulted in severe respiratory illness.
Symptoms High fever & cough Pneumonia Respiratory failure septic shock Multi-organ failure leading to death
FACTS
A total of 40 people in Saudi Arabia, Qatar, Jordan, the United Kingdom (UK), the United Arab Emirates, and France were confirmed to have respiratory illness caused by a novel (new) coronavirus. (From September 2012 to date) 44 out of 135 people died (12th Aug) .

Zoonoses infections examples Swine Flu (H5N1)
A virulent, rare strain of E.coli known as O104:H4 was identified as the source of the infections outbreak that struck Germany and France in the spring and summer of 2011.
The main reservoir hosts of these starins are the ruminants, including cattle, sheep, goats, and cervids. In many cases, human infection occurs via consumption of vegetal and animal foodstuffs contaminated by the faeces of ruminants (mainly cattle)
E.coli O104:H4 transmits into humans through either consuming or handling contaminated food or water or through contact with infected animals

A total of 138 people in Saudi Arabia, Qatar, Jordan, the United Kingdom (UK), the United Arab Emirates, and France were confirmed to have respiratory illness caused by a novel (new) Corona Virus (From September 2012 to date). 60 out of 138 people died (~50% mortality rate, 14th Oct., 2013).
MERS CoV is beta Corona Virus, and is different to other corona viruses affecting humans (this is most similar to Corona Viruses found in bats)
Germs causing NOvel infections Newly identified diseases caused by a previously known germs:
Helicobacter pylori was recognized to be associated with chronic gastritis and gastric ulcers (contradicting the conventional thinking that no bacterium can live in the human stomach due to extensive amounts of strong acids it produces)
These germs which were known to be harmless, can invade into body causing life threatening diseases.
Few strains of Klebsiella pneumoniae can cause urinary tract infection
Blood infection may lead to bacteraemia and meningitis, and without treatment on time, it can be fatal
Most strains of E.Coli are harmless, but few can cause mild to life-threatening illnesses such as Pneumonia.
Germs causing NOvel infections Toxic Shock Syndrome (TSS): TSS is a good example of a condition discovered only in 1999.
Although the symptoms lead to the discovery and definition of TSS as a new infection, the micro organisms causing this are S.aureus & S.pyogenes.
These bacteria invade the body’s bloodstream and release poisonous toxins.
These toxins cause a sudden high fever and a massive drop in blood pressure (shock), resulting in dizziness and confusion.The toxins also damage tissue, including skin and organs, and can disturb many vital organ functions.
TSS is a rare but lifethreatening bacterial infection. If it is left untreated, the combination of shock and organ damage can result in death.
More virulent strains of
Germs These strains have a large number of dangerous genes, resulting in production of Shiga toxins in human hosts.
Common disease causing germs can transform to acquire genes that leads to increased virulence to human hosts. These strains are strong enough to cause diseases in human beings. Examples: Escherichia coli O157:H7, Escherichia coli O104:H4.
Shiga toxins kills RBCs causing Hemolytic Uremic Syndrome leading to kidney failure and related complications.

ROLE OF LIFEBUOY

Significance of Hand washing Prevention of germs through hand washing Reduced incidence of diseases: Hand washing with soap can help reduce many commonly occurring problems like skin infections, eye infections, Intestinal worms, Swine flu, Pandemic flu, SARS, Avian Flu, Trachoma, Parisitic worm infections, Neonatal mortality, school absenteeism, sickness in AIDS patients and chronic malnutrition.
Importance of Hand washing: Germs are the main cause of various diseases. As they are everywhere, they are difficult to avoid. Hand washing with soap has been sited as the simplest and the most cost effective interventions to prevent spread of diseases
Simple solution to stay protected:
Hand washing and child mortality rate
There is consistent evidence that hand washing with soap at critical times including before eating or preparing food and after using the toilet can reduce diarrheal risk by about 45%
Hand washing with soap has been cited as one of the most effective interventions to reduce child mortality and morbidity with its subsequent impact on overall health and school attendance. This simple act can play a crucial role in reducing diarrheal related deaths and diseases.
Practice of Hand Washing Hand washing rates for different occasions
Despite the Evidence:
19%
After cleaning child stools
The practice of hand washing with soap is low. An 11 country review of hand washing behavior shows that on an average only 17% of the mothers wash their hands with soap after having used the toilet, and 45% wash their hands without soap (water only)
13% Before handling food
This is despite universal presence of soap in households
Lifebuoy's Heritage About Lifebuoy
To bring safety, security and health to five billion people around the world, through the active promotion of hand washing with soap.
Started and invented by William Lever, Saving Lives in 1894
“To make cleanliness common place; to lessen work for women; to foster health and contribute to personal attractiveness, that life may be more enjoyable and rewarding, for the people who use our products�
Affordable Hygiene Against Cholera Outbreak in Victorian England
LAUNCHED IN THE UK IN 1894, Lifebuoy is one of Unilever’s oldest brands, and has championed a message of health through hygiene for more than a century One of Unilever’s founders, William Lever, launched the Lifebuoy brand to help bring affordable hygiene to Victorian England at a time when epidemics of typhoid, smallpox, cholera and diphtheria were a constant threat. Today Lifebuoy products are sold in more than 34 countries in Asia and Africa, and every second 91 families buy a Lifebuoy product, trusting the Lifebuoy brand for their family’s health.
No. 1
The Lifebuoy Clinical Trial in 2007/8 demonstrated that by following the Lifebuoy Way (washing hands at 5 key occasions during the day), episodes of diarrhoea in target children reduced by 25% and target children had 40% less days off school due to illness, compared with the control group.
Lifebuoy was the world’s first health soap when it was launched in 1894, and it is still the world’s no.1 selling germ protection soap today*.
Role of Lifebuoy Child Disease burden & potential of hand washing with soap
Many of these deaths can be averted by the simple act of hand washing with soap.
Mortality Rates
Each year, more than 2.1 million of our million of our world’s children don’t live to celebrate their fifth birthday because of diarrhea and pneumonia. Diarrhea kills more children each year than AIDS, malaria and measles combined.
Washing with the soap reduced the incidence of the presence of any type of faecal bacteria on peoples hands from 44% to 8%, whereas hand washing with only water reduced the incidence to only 23%. Hand washing with soap at scale will result in the reduction of the world’s two biggest causes of child mortality – acute respiratory infections and diarrhea.
Hands are the principal carriers of disease causing germs. Water alone is not enough to wash hands as shown by studies.
Small actions. Big difference Every 15 seconds, one child dies from diarrhea and pneumonia. That’s 2 million children every year. Many of these deaths have been averted by the simple act of hand washing with soap Lifebuoy has committed to help 1 billion people improve their hygiene habits by 2015 To date we have reached 130 million people
We have demonstrated that when children wash their hands with Lifebuoy, diarrhoea is reduced by 25%, acute respiratory infections by 19% and school absence by 40%
A simple act of hand washing can save lives Over 40% of under 5 deaths occur during the neonatal period i.e. first 28 days after birth 3.1 million neonatal deaths occur every year The simple act of hand washing with soap can reduce this figure by upto 70% Despite this, only 17% of mothers wash their hands with soap after the toilet; this figure drops to 2% among mothers with children under one year Lifebuoy runs a neonatal program which explains the link between newborn survival and hand washing with soap which includes-
• • • •
Post defecation (mother) Post – contact with the baby faeces Before touching the umbilical cord After couching / sneezing on hands
Lifebuoy is spearheading a hand washing movement to help every child around the world reach 5

Germs are fast evolving, how has Lifebuoy evolved to spin a fast one on the germs Germs are evolving at an alarming rate and are increasingly becoming immune to medicines Evolved germs can be defined as germs that qualify to one or more of the below criterion:
1) Anti biotic resistant strains – MRSA, E.coli ESBL, NDM-1 K. pneumoniae 2) Entirely novel strains - H7N9, H5N1, Enterovirus 71 Germs from Zoonotic origin - E.coli O104 3) Germs causing novel Infections - S. aureus Toxic shock syndrome 4) Germs Novel to region - Novel Corona virus in Middle east 5) More virulent strains of Germs - E.coli 0157, V.cholerae 0139
Lifebuoy's Innovation to avert this crisis To enhance prevention of such diseases Lifebuoy has developed a unique patented technology to avert these diseases
Developed with Activ Naturol Shield, a unique combination of pine and thyme along with the best of skin cleansing ingredients it provides complete germ protection than other germ protection soaps
