Bacteriology had it wrong for the past 300 years. Bacteria don't live alone. They live collectively in layers of slime where they do their own thing but do it together.

Bacteria growing in communities contribute DNA as a biofilm scaffold and also to provide protection against host antibacterial peptides.

Spices contain natural antibiotic phytochemicals, as well as Quorum Sensing Inhibitors that turn pathogens into harmless targets for our immune system.

Some bacteria have an additional layer outside of the cell wall called the glycocalyx. This coating of macromolecules protects the cell and helps it adhere to surfaces.

Dental caries or cavities are caused by acidic metabolites produced by bacteria that normally inhabit the mouth, where they feed on carbohydrates.

The species concept of stable genetic composition does not apply to the complex, promiscuous community of the digestive tract. The gut environment defines gut flora.

Research on microbes that cheat during quorum sensing may give scientists a novel weapon against bacteria that cause serious health problems in Cystic Fibrosis patients.

Klebsiella bacteria in gut biofilms produce hydrogen gas that powers the electron transport chains of stomach Helicobacter implicated in gastric ulcers and cancer.

Most Gram-negative bacteria have hair-like projections external to their cell's wall. One type, fimbriae, allows bacteria to stick together and attach to host cells.

Morning's the worst of it; when that sticky, smelly film covers teeth and tongue. Some call it morning breath, or dragon breath, but what really causes halitosis?

These outbreaks occurred in hotels, hospitals, nursing homes, cruise ships, prisons. The dominator was a bacterium that at times was caused by water and contaminated soil

We take showers to get rid of grime, dust, and bacteria that may threaten our health. It turns out that doing that may be counterproductive. What to do? Read on.

Acanthamoeba spp., amoebae that live in water and soil, can hitch a ride on a contact lens, then invade a vulnerable eye and destroy the cornea.

Research shows that honey is a safe and effective wound healing agent. Infected wounds especially benefit from honey's antibacterial properties.

People have long been obsessed with germs, microbes and bacteria-harboring items, but how much danger really lurks in the unseen pathogens of our time?

In this simple classroom experiment students take oral swab samples to see if the use of mouthwash reduces the number and variety of oral bacteria found in the mouth.

Sometimes the only symptom of a Urinary Tract Infection in the elderly is acute confusion. Learn about UTI symptoms, risk factors, and preventive measures for seniors.

SDS-PAGE is a refined modern research tool, invaluable for forensics, medicine, biology. PAGE and PCR have dramatically advanced scientific inquiries of DNA and proteins.

Factors which can contribute to bacterial resistance to antibiotics and antimicrobial drugs include patient health, antibiotic choices and bacterial characteristics.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do aminoglycosides destroy bacteria without hurting our cells?

Tea tree oil and other essential oils may be effective against antibiotic resistant strains of bacteria, including staph.
