Cytologic features of normal canine ovaries in different stages of estrus with histologic comparison.

Background: Cytologic evaluation plays an important role in the diagnosis of ovarian neoplasia in dogs, but is supported by only scant information on cytologic features of canine ovaries.

Objective: The aim of this study was to provide detailed cytologic descriptions of normal canine ovaries in different stages of estrus with comparison to histologic features.

Methods: Client-owned dogs admitted for elective ovariohysterectomy were studied.

Detection and molecular characterization of Mycobacterium celatum as a cause of splenitis in a domestic ferret (Mustela putorius furo).

Mycobacterium celatum is a slow growing non-tuberculous mycobacterium described mainly as occurring in human patients. Only two cases of infection with this pathogen have been reported previously in animals. A 5-year-old, neutered male ferret was presented with progressive weight loss and muscle atrophy.
