Objective: Sample Population: Procedures: Results: Conclusions and Clinical Relevance: To compare macrostructural and microstructural features of proximal sesamoid bones (PSBs) from horses with and without PSB midbody fracture to gain insight into the pathogenesis of PSB fracture.PSBs from 16 Thorou...

The availability of accurate diagnostic tests is essential for the detection and control of Toxoplasma gondii infections in both definitive and intermediate hosts. Sensitivity, specificity and the area under the receiver-operating characteristic (ROC) curve are commonly used measures of test accurac...

Objective - To investigate herd characteristics and management practices associated with a high seroprevalence of Mycobacterium avium subsp. paratuberculosis (MAP) in dairy herds in central California. Sample Population - 60 randomly selected cows from each of 21 dairy herds. Procedures - Sera of se...

The objective of this study was to determine if viable Mycobacterium avium subsp. paratuberculosis (MAP) was present in waste milk delivered and fed to calves on California calf ranches. Four calf-raising facilities in the Central Valley of California that fed pasteurized waste milk to calves were e...

Objective: Sample Population: Procedure: Results: Conclusions and Clinical Relevance: To determine the distribution for limbs and bones in horses with fractures of the proximal sesamoid bones and relationships with findings on palmarodorsal radiographic images.Proximal sesamoid bones obtained from b...

One hundred and ninety-one sera from horses that recently were exposed to West Nile virus (WNV) by either vaccination or natural infection or that were not vaccinated and remained free of infection were used to evaluate fluorescent microsphere immunoassays (MIAs) incorporating recombinant WNV envelo...

Objective - To estimate the analytic sensitivity of microscopic detection of Toxoplasma gondii oocysts and the environmental loading of T. gondii oocysts on the basis of prevalence of shedding by owned and unowned cats. Design - Cross-sectional survey. Sample Population - 326 fecal samples from cats...

The purpose of this study was to determine the effect of blood contamination of cerebrospinal fluid (CSF) on the results of indirect fluorescent antibody tests (IFATs) for Sarcocystis neurona and Neospora hughesi. The in vitro study used antibody-negative CSF collected from non-neurologic horses imm...

Objective: Animals: Procedures: Results: Conclusions and Clinical Relevance: To measure the frequency and magnitude of reduced fibrinogen binding in a population of horses from a Thoroughbred breeding farm.444 Thoroughbred horses, 1 to 27 years old, including 316 females, 72 geldings, and 56 sexuall...

OBJECTIVE: To evaluate flow cytometric analysis for sex identification in 3 psittacine species, establish reference values for blood cell DNA content for each species, and determine effects of sample storage on DNA content. ANIMALS: 36 orange-winged Amazon parrots, 41 budgerigars, and 39 cockatiels....
