Microbiology: Disease Causative Organisms and Characteristics
Spore-Forming Organisms
- Pseudomembranous colitis (antibiotic-associated), gas gangrene, and anthrax are initially introduced into the host in the form of spores.
- Diphtheria is not introduced into the host in the form of spores.
Proteus Mirabilis Characteristics
- Proteus mirabilis is associated with the formation of calculi.
- It forms a pH of 8.
- It does not ferment lactose.
- It is not associated with urine at pH less than 8.
Differentiation of Vibrio Cholerae
- Classical and El Tor V. cholerae are differentiated according to their production of cholera toxin.
- Lactose fermentation, sucrose fermentation, and resistance to polymyxin B are not criteria for differentiating between classical and El Tor V. cholerae.
Shigella Antigens
- H antigen is a type of Shigella antigen.
- K antigen is also a type of Shigella antigen.
