Differential genetic regulation of canine hip dysplasia and osteoarthritis.

Background: Canine hip dysplasia (HD) is a common polygenic trait characterized by hip malformation that results in osteoarthritis (OA). The condition in dogs is very similar to developmental dysplasia of the human hip which also leads to OA.

Methodology/principal Findings: A total of 721 dogs, including both an association and linkage population, were genotyped.

Virologic survey of dogs with naturally acquired idiopathic conjunctivitis.

Objective: To determine the frequency of viral detection in conjunctival samples from client-owned domestic dogs with naturally acquired idiopathic conjunctivitis and to identify signalment, historical, and clinical findings positively associated with viral detection.

Design: Case-control study.

Animals: 30 dogs with naturally acquired idiopathic conjunctivitis and a control population of 30 dogs without ocular disease.

Estimation of heritabilities, genetic correlations, and breeding values of four traits that collectively define hip dysplasia in dogs.

OBJECTIVE-To estimate heritabilities and genetic correlations among 4 traits of hip joints (distraction index [DI], dorsolateral subluxation [DLS] score, Norberg angle [NA], and extended-hip joint radiograph [EHR] score) and to derive the breeding values for these traits in dogs. ANIMALS-2,716 dogs of 17 breeds (1,551 dogs in which at least 1 hip joint trait was measured). PROCEDURES-The NA was measured, and an EHR score was assigned.

Eurytrema procyonis and pancreatitis in a cat.

A young adult male domestic shorthair cat was presented for physical examination, routine vaccinations, and a fecal examination. Physical examination revealed no significant abnormalities. Eggs of the raccoon pancreatic fluke Eurytrema procyonis were detected by fecal flotation.

Clevudine inhibits hepatitis delta virus viremia: a pilot study of chronically infected woodchucks.

In a small controlled study, clevudine, a potent inhibitor of hepadnaviruses, including hepatitis B virus and woodchuck hepatitis virus, suppressed hepatitis delta virus (HDV) viremia in chronically infected woodchucks. Suppression was correlated with the marked reduction of woodchuck hepatitis virus surface antigen in individual animals, consistent with the concept that repression of surface antigen expression may be a useful antiviral strategy for HDV.
