Bacteria Database

E. coli is a gram-negative, facultative anaerobic bacterium commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless and part of normal gut flora, but some can cause serious food poisoning.

S. aureus is a gram-positive, round bacterium that is a common member of skin flora. It can cause a range of illnesses from minor skin infections to life-threatening diseases such as pneumonia and sepsis. MRSA strains are resistant to many antibiotics.

L. acidophilus is a gram-positive, rod-shaped bacterium found in the human gut and vaginal tract. It is a probiotic that helps maintain healthy gut flora, aids in digestion, and may help prevent infections.

B. fragilis is an obligate anaerobic gram-negative bacterium that is a normal member of the human gut microbiome. It plays important roles in polysaccharide breakdown and immune system development but can cause infections if it escapes the gut.

H. pylori is a spiral-shaped, gram-negative bacterium that colonizes the stomach lining. It is associated with gastritis, peptic ulcers, and increased risk of stomach cancer. Its unique helical shape and flagella allow it to penetrate the gastric mucosa.

B. bifidum is a gram-positive, anaerobic bacterium abundant in the gut microbiome, especially in infants. It helps ferment dietary fibers, produces vitamins, and supports immune function. It's commonly used as a probiotic.

S. thermophilus is a gram-positive, facultative anaerobic bacterium used in yogurt and cheese production. It's also a probiotic that may improve lactose digestion and support gut health.

A. muciniphila is a gram-negative, strictly anaerobic bacterium that resides in the gut mucus layer. It's associated with metabolic health, gut barrier integrity, and may play a role in obesity and diabetes management.
