Nearly two-thirds of Queensland, Australia, sheep graziers who detect lice (Bovicola ovis) in their flocks do so by fleece parting or visual inspection of the skin for lice. However, visual inspection is known to have low sensitivity which varies with the number of lice per infested sheep. This repo...

The sensitivities and specificities of 17 antibody detection tests for brucellosis in goats were estimated. Tests evaluated included the USDA card test with 8% cell concentration (8%Card), USDA rapid automated presumptive test (RAP), Mexican Rose Bengal plate tests with 8 and 3% cell concentrations ...

A portable modified steel mesh panel trap was developed to reduce injuries that wild pigs (Sus scrofa) suffer when captured in simple square panel traps. Immobilization was done with a drug combination of Telazol® (zolazepam and tiletamine) and xylazine hydrochloride (HCl) injected with blow darts....

A cohort of 95 piglets born to 12 sows seropositive for Mycoplasma hyopneumoniae (MH) was followed from birth until passively acquired MH antibodies, detected with an ELISA, reached their lowest concentration. The objectives of the study were to determine the half-life of maternally derived MH antib...

Shoe characteristics of Thoroughbred racehorses that died or were killed at California race-tracks between August 1992 and July 1994 were measured. Percentage of agreement was used to compare shoe characteristics between limbs. Using χ² analysis, shoe characteristics were compared between horses g...

Thirteen morphologic characters were evaluated on P. cuniculi to determine if measurements for these variables were influenced by the use of different fixatives and varying periods of fixation. Morphological structures composed primarily of chitin (outer opisthosomal setal lengths and right 3rd tars...

A case-control study was conducted in the Mexicali Valley to identify risk factors for goat-herd seropositivity for Brucella melitensis. Nineteen case herds (≥2 positive results with the 8% rose bengal plate test (RBT)) and 55 control herds (zero positive results in RBT), matched for herd size and...

Dehydroepiandrosterone (DHEA) has been shown to have antiobesity activity in rodents and spontaneously obese dogs. This study evaluated the effect of DHEA or placebo combined with a low-fat/high-fiber diet in spontaneously obese dogs in a clinical trial. Spontaneously obese, euthyroid dogs, referred...

Furunculosis occurs in all of the Atlantic Canadian provinces of Newfoundland, Nova Scotia and New Brunswick but not Prince Edward Island. Aeromonas salmonicida has been isolated from both wild and cultured salmonids and non-salmonids. Only "atypical A. salmonicida" (A. salmonicida subsp. ...

The objective of this ultrastructural investigation was to determine if populations of pericytes in equine dermal and skeletal capillaries increase in a head-to-foot direction, as has been reported in human skeletal muscles. Samples of equine microvessels were obtained from the longissimus dorsi ske...

In confined pig herds, located in Northwest-Germany and affiliated to a hybrid breeding organisation, 3 retrospective observational studies were performed looking at data collected before and after 1988 to study the effects of seasons on sow fertility. A subsequent field trial with 8 pig herds in 19...

An agar gel immunodiffusion (AGID) test to detect group-specific antibodies to infection of cattle by bluetongue viruses was evaluated using field collected sera in Queensland, Australia. The AGID test was compared to the serum neutralization (SN) test used to detect serotype-specific bluetongue vir...

Parasitism by strongylate nematodes has been a continuing concern in exotic ungulates kept in large multispecies enclosures at the San Diego Wild Animal Park. In an attempt to evaluate and modify the existing control program, 9 species of the subfamilies Antilopinae and Hippotraginae were followed o...

BACKGROUND: Taste buds on the pig tongue have been neither studied in detail nor quantified. We have counted the numbers of fungiform and vallate papillae, estimated their taste bud densities, and computed numbers of taste buds per volume of papilla on porcine tongue. Pig was chosen for this work be...

Estimates of the association between enzootic pneumonia (EP) and weight gain were obtained from multiple linear regression models using coughing episodes or slaughter checks as indicators of EP status in a prospective cohort study in a commercial pig herd. Models were estimated for pigs in 2 differe...

A cohort of 57 pigs in a farrow-to-finish swine herd with mild clinical mycoplasmal disease was followed to determine patterns of seroconversion to Mycoplasma hyopneumoniae (MH), detected with an enzyme-linked immunosorbent assay (ELISA). Survival analysis was used to evaluate the relationship betwe...

Ecological monitoring and its associated research programs have often provided answers to various environmental management issues. In the face of changing environmental conditions, ecological monitoring provides decision-makers with reliable information as they grapple with maintaining a sustainable...

The causes of morbidity and mortality in 17 free-living raptorial bird species of northern California between 1983 and 1994 were studied. Of 409 birds examined at the Veterinary Medical Teaching Hospital, University of California, USA, 58% died of traumatic injuries and 30% died of infectious diseas...

Sera from 111 Ovis canadensis and 95 Odocoileus hemionus from california, USA, were tested using an indirect immunofluorescence assay for antibodies to 2 isolates of Babesia spp. recently obtained from these hosts in California. The study populations were from 6 locations: 3 areas of real or potenti...

Selenium concentration was measured in paired maternal blood samples and fetal liver specimens collected at a San Joaquin County, California, abattoir (beef = 19, dairy = 54) and from bovine aborted fetuses submitted to the California Veterinary Diagnostic Laboratory System (CVDLS; beef = 20, dairy ...

A description of earlier work that demonstrated that cattle inoculated with a polynucleotide vaccine encoding bovine herpesvirus type 1 (BHV-1) gD are protected from challenge with virulent BHV-1. More recently, a mouse model has been used to identify the main parts of immunomodulation by polynucleo...

Factors associated with umbilical hernias were evaluated in a 320-sow, farrow-to-finish herd. Health, production, and treatment records for a cohort of 2958 pigs were used to determine whether umbilical infection and sire of the pig increased the risk of herniation. Although herniation was infrequen...
