Epidemiologic analysis of nosocomial Salmonella infections in hospitalized horses.

Objective: To examine the relationship between abdominal surgery and nosocomial Salmonella infections and the relationship between high caseload in combination with abdominal surgery and nosocomial Salmonella infections in hospitalized horses with signs of gastrointestinal tract disease.

Animals: 140 horses.

Design: Case-control study.

Consensus nested PCR amplification and sequencing of diverse reptilian, avian, and mammalian orthoreoviruses.

The orthoreoviruses are segmented RNA viruses that infect diverse vertebrate host species. While the most common human orthoreovirus, Mammalian Reovirus, is not typically associated with significant disease, the majority of Orthoreovirus species have been shown to cause significant and often fatal disease in reptiles, birds, and primates. There is significant potential for jumping species.

Antimicrobial testing of selected fluoroquinolones against Pseudomonas aeruginosa isolated from canine otitis.

A total of 100 Pseudomonas aeruginosa (P. aeruginosa) isolates were collected over a 1.5-year period from cases of canine otitis.

Risk factors associated with fecal Salmonella shedding among hospitalized horses with signs of gastrointestinal tract disease.

Objective: To estimate prevalence of and identify risk factors for fecal Salmonella shedding among hospitalized horses with signs of gastrointestinal tract disease.

Design: Cross-sectional study.

Animals: 465 hospitalized horses with gastrointestinal tract disease.

Evaluation of a commercially available hyperimmune plasma product for prevention of naturally acquired pneumonia caused by Rhodococcus equi in foals.

Objective: To determine efficacy of a commercially available hyperimmune plasma product for prevention of naturally acquired pneumonia caused by Rhodococcus equi in foals.

Design: Randomized clinical trial.

Animals: 165 foals.
