M. catarrhalis is a pink/brown, circular bacteria found in pairs. First reported in 1896 as Micrococcus catarrhalis, later renamed Moraxella. Two species exist: type 1 seroresistant (4 million years ago) and type 2 serosensitive (50 million years ago)
E. faecalis is a harmless bacteria found in GI tract and oral cavity. Most common cause of urinary tract infections among enterococci species. Forms biofilms that are resistant to antibiotics
Vibrio is a Gram-negative bacteria with curved-rod shape. Highly salt tolerant and found in various salt water environments. All members are motile with polar or lateral flagella. Contains two chromosomes, unusual for bacteria
Bacillus is a genus of Gram-positive, rod-shaped bacteria with 266 named species. Can be aerobic or facultative anaerobic, forming oval endospores. Cell walls contain teichoic and teichuronic acids. Named by Ehrenberg in 1835 for rod-shaped bacteria
Gram-positive bacterium found in skin and marine environments. Forms white, raised colonies 1-2 mm in diameter. Facultative anaerobic, catalase-positive, coagulase-negative. Can survive in warm, moist environments
Prevotella is a genus of Gram-negative bacteria with 57 characterized species. Widely distributed across habitats, especially in swine gut microbiome. Forms part of oral, vaginal, and gut microbiota in humans
