Chemotactic responses of neutrophils in cats with spontaneous feline infectious peritonitis.

The culture supernatant of peritoneal exudate cells (PEC) from cats with effusive feline infectious peritonitis (FIP) was chemotactic for peripheral blood neutrophils (PBN) from healthy cats, magnitude of the chemotactic activity being approximately 10-fold lower than that in zymosan-activated fresh serum of healthy cats (ZAS). The migration profile of PBN from healthy cats was slightly different between the PEC culture supernatant and ZAS. These findings suggest that the chemotactic activity detected in the PEC culture supernatant is distinct from that in ZAS. The chemotactic responses of PBN from FIP cats to ZAS were reduced, as compared with that from healthy controls. In contrast, the neutrophil chemotactic response and sensitivity to the PEC culture supernatant in FIP cats were not remarkably different from those in healthy controls. Furthermore, the chemotactic responsiveness of PEC from FIP cats to ZAS was slightly different from that of PEC to the PEC culture supernatant. These results suggest that neutrophils from FIP cats have altered reactivities against these chemoattractants.

Isolation of Cryptococcus neoformans var. neoformans from canine otitis.

Cryptococcus neoformans was demonstrated in the clinical material of a 15-year-old male dog with a history of chronic otitis externa by employing Helianthus annuus seed agar as a selective medium. The examination of the isolate for sexual compatibility on modified Helianthus annuus seed medium revealed that it belonged to Filobasidiella neoformans var. neoformans 'alpha' mating type. In the authors' view, this appears to be the first report of isolation of Cr. neoformans var. neoformans from diseased ear of a dog.
