A study was undertaken to determine the blood chemical variables and compare changes that occurred with ruptured bladders and ruptured urethras in steers and yearling bulls. The fatality rates were 10.5% in steers with ruptured urethras and 50.8% in steers with ruptured bladders. Both groups had sig...

Electrolyte and urea levels of vitreous humor collected from bovine eyes at various times postmortem, were compared with serum levels in the same animals. Provided the vitreous humor was filtered immediately after collection, measured levels of total calcium (Ca), potassium ions (K+), sodium ions (N...

The complexity and uncertainty of diagnostic information makes the diagnostic process difficult to learn, teach, and practice. Fuzzy logic methods, used successfully with complex industrial control problems, may be appropriate to model the range of uncertainties found in medical diagnostic informati...

Changes in hematopoietic and lymphoid tissues of young Swiss mice fed a balanced semipurified diet containing T-2 toxin (20 ppm) were examined after one, two, three, four or six weeks. During the first three weeks of exposure of T-2 toxin, lymphoid tissues, bone marrow and splenic red pulp became hy...

The life cycle of Eimeria falciformis var. pragensis, established from a single oocyst, is described in experimentally infected mice (Mus musculus). The coccidium had a prepatent period of 7 days and a patent period of 10--16 days. Oocysts were spherical to ellipsoidal in shape and measured 21.2 x 1...

Enterotoxigenic colibacillosis was experimentally produced in four colostrum-deprived calves given 10(10) Escherichia coli strain 210 (serotype 09+:K30+:K99-:F41-:H-) orally and the histopathological changes compared to those seen in colostrum-fed calves infected in an earlier study with strain B44 ...

Several antibody preparations were tested for their ability to reduce adsorption of Vibrio cholerae to isolated intestinal epithelial cells, and this ability was related to agglutination and protective activity in infant mice. The results demonstrate that (1) the reduction in adsorption of V. choler...

Various hypotheses have been proposed for the pathogenesis of the neurological signs associated with bovine enteric coccidiosis. We undertook a prospective study of cases of bovine enteric coccidiosis with and without nervous signs to test the validity of these hypotheses and explore other possible ...

This study was carried out to determine the diagnostic usefulness of postmortem eyefluid analysis in estimating antemortem concentrations of serochemical constituents. A total of 31 cattle, 18 dogs and 22 cats were selected from routine elective euthanasia submissions to a diagnostic laboratory. For...

A laboratory quality assurance (QA) program can minimize errors and provide confidence in the validity of laboratory test results. The structure of a QA program varies somewhat among laboratories but usually requires addressing a QA manual, QA goals, quality of resources, standard operating procedur...

The immunogenicity of the different stages of Eimeria falciformis var. pragensis was evaluated with the indirect fluorescent antibody reaction. Sporozoites, mature asexual stages and merozoites treated with sera from immune mice and with fluorescein-conjugated goat anti-mouse gammaglobulin showed th...

The microhematocrit heat-precipitation methods of Millar et al (1971) and Schalm et al (1975) were compared with the reference clottable protein method of Ratnoff and Menzie (1951) in the measurement of plasma fibrinogen concentration in horses. The millar et al method was more precise and accurate ...

Mice immunized with infections of 500, 5,000, or 20,000 oocysts of E. falciformis var. pragensis were reinfected with 20,000 and 100,000 oocysts at 20 and 38 days, respectively, after the initial infection. After the first challenge infection, none of the immunized mice showed clinical signs of cocc...

A rapid radioimmunoassay method for detecting plasma cortisol was evaluated and the results found to be accurate, precise and reproducible. Sample storage and preparation were examined; refrigeration and delayed serum separation decreased the cortisol concentration but freezing for up to six months ...

By using pigs sensitized to bovine serum albumin (BSA), it was found that exposure of the intestinal mucosa to BSA induced, in 4 h, the emigration of large numbers of neutrophils into the intestinal lumen. This response was specific for the immunizing antigen and could be transferred to nonimmune an...

Reported are the results of preliminary attempts to characterize the molecular weight, heat sensitivity and other features of a labile neurotoxin identified in the serum of calves exhibiting neurological signs in association with coccidial enteritis. The labile neurotoxin activity is heat labile (60...

Fatal myopathy similar to "capture myopathy" described for African game was diagnosed in a wild white-tailed deer. Clinical signs included depression, inability to rise or stand, and myoglobinuria. Values for serum creatine phosphokinase, glutamic oxaloacetic transaminase, and blood urea n...

A malignant neoplastic process originating from gall bladder epithelium was diagnosed in a 14-year-old, spayed female, domestic shorthair cat. The tumor produced widespread pulmonary and lymphatic metastases. The clinical and pathological manifestations are described. Neoplasia arising from the gall...

Zinc absorption from a test dose of (65Zn) zinc chloride was increased in mice with a high capacity to absorb iron induced by a low-iron diet. When radiolabelled zinc chloride in concentrations varying from 0.025 to 0.30 mM was perfused through open-ended duodenal loops of mice fed this diet, the pr...
