Supplement

Pasteurella pneumotropica has a size of about 0.5-1.2 micrometer that produces acid by using glycerol, inositol, dextrose, maltose, lactose and mannose. It is catalase-oxidase positive and has the capability to reduce nitrate to nitrite.

Pasteurella pneumotropica contains a strong hydrophilic capsule that used for protection against dehydration, improves transmission from host to host and survival in harsh environment. It is known that an encapsulated strain is more resistant to phagocytosis than those without capsule.

Pasteurella pneumotropica isolated mostly in urogenital tract, respiratory tract and conjunctiva of various animals including hamster, rats, mice, guinea pigs, rabbits and cats. It has been implicated as an infective agent in chronic subclinical infections including pulmonary infections, uterine infections, enteric infections and ocular infections. In some other cases it can cause cellulitis, endocarditis, meningitis, bone and joint infections.
