Bacteria from a cat's tongue. Coloured scanning electron micrograph (SEM) of bacteria isolated from a cat's tongue. The two most frequently found bacteria are pasteurella and clostridium. Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus belonging to the Pasteurellaceae family. In humans, pasteurella multocida is the most common cause of infection from wound infections after cat bites. Many mammals (including domestic cats and dogs) and birds harbor it as part of their normal respiratory microbiota. Clostridium villosum is an obligately anaerobic, rod-shaped, spore forming, nonmotile organism which is gram positive in its early stages of growth and gram negative after 18 to 24 hours. The commonest anaerobic bacterium in feline oral flora is also often associated with abscess formation from cat bites. Magnification: x2700 at 10 centimetres wide.
