Gram-negative bacteria found in intestinal tracts of humans, mammals, and reptiles. Cells are straight rods, 0.6-0.7 μm diameter and 1.0-1.7 μm length. Produces catalase, indole, urease, and methyl red enzymes. Divided into subspecies: subsp. morganii and subsp. sibonii
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
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)
M. genitalium is a small, sexually transmitted bacterium found in human urogenital tract. First isolated in 1981, identified as new species in 1983. Genome consists of 580,070 base pairs, making it one of smallest organisms. Can adhere to host cells using proteins P110 and P140
Born in 1881 in Scotland, Fleming studied at Royal Polytechnic Institution. Joined St Mary's Hospital Medical School in 1903, becoming bacteriologist. Served in Royal Army Medical Corps during World War I
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
