Overview of Clinical Pathology and the Horse.

This article is intended to serve as a reference for clinical pathology in the equine with algorithms and tables provided for anemia diagnosis and leukogram alterations associated with both acute and chronic inflammation. A table of reference is provided for fluid evaluations including joint fluid and effusions into body cavities. Evaluation of newer serum markers, such as cardiac troponin, and a table highlighting test procedures for the evaluation of endocrine disease in the horse are included.

Cryptococcosis: update and emergence of Cryptococcus gattii.

Cryptococcosis is a fungal disease that occurs throughout the world. Recent reclassification of Cryptococcus species along with a change in the distribution pattern has prompted reevaluation of the organism and the diseases caused by this pathogen. This review highlights the emergence of Cryptococcus gattii as a primary pathogen in North America and summarizes our current understanding of the disease in mammals and birds.

Bartonella henselae in captive and hunter-harvested beluga (Delphinapterus leucas).

Previously, we reported the isolation of Bartonella henselae from the blood of harbor porpoises (Phocoena phocoena) and loggerhead sea turtles (Caretta caretta) from the North Carolina coast. Hematologic, pathologic, and microbiologic findings surrounding the death of a juvenile captive beluga in Vancouver initiated an outbreak investigation designed to define the molecular prevalence of Bartonella infection in belugas. Using polymerase chain reaction analyses targeting the intergenic spacer region (ITS), two B.

Anaplasma phagocytophilum infection (granulocytic anaplasmosis) in a dog from Vancouver Island.

A 7-year-old Labrador retriever had nonspecific clinical signs that included lethargy, malaise, and difficult ambulation. The dog was native to Vancouver Island, British Columbia, and had never left this area. Morulae were identified in polymorphonuclear cells.

Clinicopathologic features of an unusual outbreak of cryptococcosis in dogs, cats, ferrets, and a bird: 38 cases (January to July 2003).

Objective: To determine clinical and pathologic findings associated with an outbreak of cryptococcosis in an unusual geographic location (British Columbia, Canada).

Design: Retrospective study.

Animals: 1 pink-fronted cockatoo, 2 ferrets, 20 cats, and 15 dogs.
