Infection in Laboratory Rabbits.

Sarcocystosis, presumably caused by , was diagnosed in 2 purpose-bred, SPF Dutch belted laboratory rabbits from a class A breeder. The rabbits were purchased by a research facility and conventionally housed individually in stainless-steel suspended caging. At necropsy and tissue harvest, gross lesions were not observed in the muscles.

Clinicopathologic, histologic, and toxicologic findings in 70 cats inadvertently exposed to pet food contaminated with melamine and cyanuric acid.

Objective: To document clinicopathologic, histologic, and toxicologic findings in cats inadvertently exposed to pet food contaminated with melamine and cyanuric acid.

Design: Case series.

Animals: 70 cats from a single cattery inadvertently fed contaminated food that was the subject of a March 2007 recall.

Assessment of retinal degeneration in outbred albino mice.

Evaluation of a pharmaceutical's safety includes assessment of the potential for ophthalmologic toxicity. These nonclinical studies commonly use various outbred stocks of mice. Pretest indirect ophthalmoscopic examinations in the commonly used outbred stock Hsd:ICR(CD-1) indicated that retinal degeneration was a problem in this particular outbred stock of mice.

Serum clinical chemistry and hematology reference values in outbred stocks of albino mice from three commonly used vendors and two inbred strains of albino mice.

Reference values for serum clinical chemistry and hematology parameters are often sought after when attempting to interpret clinical pathology data. Furthermore, the values of parameters may vary between laboratories depending on the techniques being used. Accordingly, laboratories should strive to generate a historical reference value database based upon the methods used.
