Disseminated aspergillosis attributable to Aspergillus deflectus was diagnosed in a Springer Spaniel with lethargy, lameness, anorexia, weight loss, pyrexia, lymphadenopathy, hematuria, and urinary incontinence. Necropsy revealed granulomatous inflammation and numerous fungal hyphae in many organs. The conidial heads of the fungus have a characteristic briar-pipe appearance in culture.

Effective control of a gentamicin-resistant Salmonella arizonae infection in turkey poults

A gentamicin-resistant Salmonella arizonae isolate was identified as the cause of an unusually high early mortality rate in several flocks of poults produced by a primary turkey breeder. The company routinely dipped its hatching eggs in 500 ppm gentamicin before incubation and injected each poult at 1 day of age with 1 mg gentamicin. Mortality was reduced to normal, but S. arizonae was not eliminated by injecting the day-old poults with higher doses of gentamicin. S. arizonae was not isolated from sample normal-sized poults in treated groups when tetracyclines were used for antibiotic inoculation of day-old poults. Tetracyclines seemed to be completely effective only when a 5-mg subcutaneous injection per day-old poult was combined with an approximately equal dose in drinking water daily for 4 days, and therapy was accompanied by the culling of runts and other debilitated poults.

Cutaneous atypical mycobacteriosis in cats

Cutaneous infection with atypical mycobacteria was observed in 6 cats. All cats had cutaneous or subcutaneous masses, with or without fistulous tracts. Diagnosis was determined by microbial culture. Transmission studies were done in 1 case. Treatment, which included antibiotics or surgery, or both, was usually unsuccessful, but remission without treatment did occur. In 3 cats available for long-term evaluation, there has been no recurrence of disease.
