Prokaryotic cells can have a variety of surface appendages - flagellum, fimbria or pilus - that enable them to move, adhere to surfaces and even infect host cells.

Fimbriae are external structures of Gram- cells which enable bacteria to adhere to surfaces and, as virulence factors, mediate infection of host cells.

In order to view individual bacteria through a light microscope, a bacterial smear must be attached to a slide and then stained. Here is the procedure.

The bacterium Acinetobacter baumannii was often ignored by doctors but now is considered a potentially lethal pathogen in hospitals, due to antibiotic resistant strains.

The mechanisms of inhibition of bacterial protein synthesis become clearer each year. The recent Nobel Prize in Chemistry rewarded the clearer understanding of ribosomes.

Differential stains and media can provide preliminary identification of microbes, but to identify Gram- bacteria to the species, a more sophisticated test is required.

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.

The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

Endospore staining involves application of a series of dyes. Malachite green stains endospores and safrinin dyes vegetative cells pink. Here's endospore stain procedure.

Bacterial contamination of the food we eat can lead to either food infection or intoxication, different types of food poisoning. They cause illness in different ways.

The future of fighting common infections may be in the development of new antibiotics or in the combination of antibiotic and non-antibiotic drug therapies.

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.

Minimising the risk of development of bacterial resistance to antibiotics is important to ensure the continued ability of physicians to treat serious infections.

Meningitis is an inflammation of the meninges that line and protect the brain and spinal cord. It occurs when bacteria or viruses breech the blood-brain barrier.

In microbiology, there are many different techniques used to identify microbes. Differential media typically provide general information regarding identity.

Pneumonia is an infection of the lungs typically caused by a bacteria, virus, or inhaled substances. Here is a look at some gram-negative bacterial causes.

Gram- bacteria stain pink due to the location of cell wall peptidoglycan and an external LPS membrane. Here's how Gram staining identifies Gram negative organisms.

Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus, but can also be caused by inhaling foreign substances.

Gram + bacteria stain purple due to the chemistry and structure of their peptidoglycan cell wall. Here's how Gram staining identifies Gram-positive organisms.

Endospores are somewhat like bacterial seeds, tough structures that allow some bacteria to go dormant under unfavorable conditions.

Bacterial Vaginosis can lead to Pelvic Inflammatory disease. Better choices leading to cleaner sexual practices is key to avoiding this potentially serious condition.

Bacteriophages reproduce by commandeering a bacterium and ultimately killing it. But sometimes, through lysogeny, the phage doesn't immediately take over its host.

Acute prostatitis is an inflammation of the prostate gland that develops suddenly.

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