Eighteen two day old conventional piglets were infected with transmissible gastroenteritis virus while six others were used as controls (Group 1). At the onset of diarrhea, infected piglets were divided into three groups of six (Groups 2, 3 and 4). Piglets in group 2 were not treated and were fed a milk replacer ad libitum. Piglets in group 3 were removed from the milk replacer and placed on an oral glucose-glycine-electrolyte solution ad libitum. Those in group 4 were placed on oral fluid therapy and received a 5% dextrose solution intraperitoneally at the rate of 25 mL/kg of body weight once a day. Blood samples were collected in heparin within minutes after the infected piglets became comatose and from the controls at four or five days of age. The following variables were measured: packed red cell volume, blood pH, total plasma protein and bicarbonate, blood urea nitrogen, and plasma glucose, creatinine, chloride, inorganic phosphorus, sodium, potassium, magnesium and calcium. Vomiting and diarrhea appeared 12 to 24 hours postinoculation in the infected piglets. There was a sudden and rapid progression into a comatose and moribund state one or two days later whether the infected piglets were treated or not.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":9546,"journal":{"name":"Canadian journal of comparative medicine : Revue canadienne de medecine comparee","volume":"49 4","pages":"357-60"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1236192/pdf/compmed00004-0009.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15186179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven days after challenge with Pasteurella, calves were killed for collection of tissues at necropsy. Each calf was given a score based on macroscopic and microscopic lesions. The scores for the calves receiving live vaccines were significantly lower (p less than 0.025) than those for the controls. Also, the calves receiving live vaccines had a significant (p less than 0.05) increase in the level of serum antibody to P. haemolytica.

{"title":"Ceruloplasmin as an indicator of copper status in cattle and sheep.","authors":"B R Blakley, D L Hamilton","doi":"","DOIUrl":"","url":null,"abstract":"The relationship between ceruloplasmin, a metalloenzyme with oxidase activity, and copper was investigated in cattle and sheep. The oxidase activity of ceruloplasmin correlated closely with the serum or plasma copper concentrations in cattle. The respective correlation coefficients were 0.83 and 0.60. In sheep serum, a correlation coefficient of 0.92 was obtained. In each instance, the relationship remained linear from the deficient to the high normal ranges of copper. Comparison of the linear regression relationships indicated the ceruloplasmin activity in bovine serum was statistically lower than the activity in bovine plasma (P less than 0.0001), through the intercepts from the regression lines of the two relationships were similar (P = 0.412). Comparisons of ovine and bovine serum-ceruloplasmin relationships indicated that a significant species difference was present. Ovine ceruloplasmin activity increased more rapidly as compared to the corresponding bovine activity over the range of copper concentrations investigated (P less than 0.0001). The intercept from the ovine regression relationship was also lower (P less than 0.0001). A correlation coefficient of 0.35 was observed between the serum ceruloplasmin activity and hepatic copper concentrations in cattle indicating that the mathematical relationship was not as well defined. Ceruloplasmin activity appears to correlate more closely with serum or plasma copper concentrations as compared to corresponding liver copper concentrations.","PeriodicalId":9546,"journal":{"name":"Canadian journal of comparative medicine : Revue canadienne de medecine comparee","volume":"49 4","pages":"405-8"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1236200/pdf/compmed00004-0057.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15186183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two commercial preparations, i.e. a beta-propiolactone killed whole S. equi cell bacterin and a cell-free extract of S. equi cells were included in the study. The mean passive hemagglutination antibody titers (10 X log2) in sera of foals given either four doses of formalin-treated whole cell vaccine or an initial dose of formalin-treated followed by three doses of heat-inactivated vaccine with or without levamisole were significantly higher two weeks after the final dose. These passive hemagglutination antibody titers were higher in foals given formalin-treated whole cell vaccine (6.7 +/- 1.5) than given commercial bacterin (4.5 +/- 2.1). The passive hemagglutination antibody titers in all the groups decreased at 12 to 16 weeks after fourth dose of the vaccine. Foals given a commercial cell-free extract did not show a significant increase in passive hemagglutination antibody titers even up to four weeks after third dose. A group of six pony foals immunized with partially-purified M protein showed mean passive hemagglutination antibody titers lower than those observed in foals given whole cell vaccines. In a challenge experiment with S. equi, two of six foals vaccinated with partially-purified M-protein and all three controls developed clinical disease. The passive hemagglutination antibody of vaccinated foals increased after challenge, while at 28 days postchallenge the passive hemagglutination antibody titers of vaccinates and recovered controls were similar.","PeriodicalId":9546,"journal":{"name":"Canadian journal of comparative medicine : Revue canadienne de medecine comparee","volume":"49 4","pages":"351-6"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1236191/pdf/compmed00004-0003.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15186820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polystyrene tubes were coated with affinity purified goat antibovine IgA, IgG1, IgG2 or IgM, washed and then incubated with purified isotypes to ascertain crossreactivity and sensitivity limits. Bound isotype was detected using the homologous affinity purified antibody conjugated to horseradish peroxidase and hydrogen peroxide-2,2-azino-di-(3-ethylbenzthiazoline sulfonic acid), as the substrate/chromogen. A standardized serum was diluted and used as a control for comparison. Several dilutions were used initially, however, determinations may be made with a single dilution, 1:200, for all isotypes. Results for 100 sera were compared to data obtained with the same samples using a radial immunodiffusion technique. A low correlation coefficient was noted between results from the two assays. Day to day variation and within test repeatability were determined for both assays using ten samples. For the enzyme immunoassay method, day to day variation for IgA, IgM, IgG1 and IgG2 determinations was 17.5, 19.3, 7.6 and 7.3% while variation in repeatability (within a test) was 6.2, 5.9, 3.3 and 4.5%, respectively. Day to day variation for the single radial immunodiffusion test for IgA, IgM, IgG1 and IgG2 was 15.4, 26.0, 11.5 and 18.3% and variation repeatability (within a test) was 11.6, 13.9, 5.9 and 8.3%, respectively. The procedures consistently detected 0.1 micrograms of immunoglobulin whereas the radial diffusion sensitivity limit was approximately 500 micrograms.","PeriodicalId":9546,"journal":{"name":"Canadian journal of comparative medicine : Revue canadienne de medecine comparee","volume":"49 4","pages":"414-8"},"PeriodicalIF":0.0,"publicationDate":"1985-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1236203/pdf/compmed00004-0066.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15050394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
