Pasturella
Pasturella is a small gram-negative oraganism that is present in
the nasopharynx and gastrointestinal tract of mammals and birds
-with cats having the highest carrier rate ( 70 - 90 %). Pasturella
DOES affect humans as well as the avian species.
Clinical manifestations in humans usually develop with 24 hours of the
bite, with the most common being cellulitis surrounding the wound.
Less common are septic arthritis, osteomyelitis, septicemia and
peritonitis.
The treatment of choice are the penicillins (eg piperacillin is
used in avian patients). Tetracyclines may be used in
penicillin-allergic patients. Erythromycin, cephalosporins, and
clindamycin are ineffective.
