Salmonella serotypes encountered in animal feed additives in Lebanon.     

N H Nabbut 《American journal of veterinary research》1978,39(5):893-895

Animal feed-additive samples (n = 300) were examined for the presence of salmonellae, using the selenite-F broth-enrichment method followed by subculturing on Salmonella-Shigella and brilliant green agar with sulfadiazine selective agar plates. Samples consisted of a variety of feed additives: 119 bone meal samples, 77 meat meal samples, 40 fish meal samples, and 64 miscellaneous meal samples. Results of examination found 49 (41.2%) of the bone meal samples, 6 (7.8%) of the meat meal samples and 2 (5%) of the fish meal samples contained salmonellae. Of 57 isolates representing 24 serotypes, 4 most frequently isolated serotypes were Salmonella meleagridis (35.1%), Salmonella tennessee (7%), Salmonella chester (5.2%), and Salmonella senftenberg (5.2%). This study shows a high Salmonella-contamination rate of bone meal compared with meat meal and fish meal samples. Of 12 known positive bone meal samples that were examined, 100% of 25-g samples, compared with 70% to 100% of 2.5-g samples and 30% to 90% of 0.25-g samples and 30% to 90% of 0.25-g samples, were positive for salmonellae.  相似文献   

Microbiology of normal and seborrheic canine skin.     

P J Ihrke  R M Schwartzman  K McGinley  L N Horwitz  R R Marples 《American journal of veterinary research》1978,39(9):1487-1489

Quantitative and qualitative bacterial assays were performed on the skin of 15 normal and 32 seborrheic dogs. Nonionic detergent scrubs were made on areas demarcated by glass sidearm cylinders. Quantitative analysis was accomplished by the serial dilution technique, and the bacteria were identified by individual and colonial morphology and by enzyme production. Areas measured on control dogs had a markedly lower total bacterial count than similar areas measured on seborrheic animals. Control dogs had a flora consisting primarily of coagulase-negative cocci, whereas seborrheic dogs usually had a cutaneous flora composed primarily of Stahylococcus aureus, coagulase-positive.  相似文献   

Parainfluenza-3 virus exposure of beef heifers prior to natural breeding.     

J W Call  R A Smart  J T Blake  J E Butcher  J L Shupe 《American journal of veterinary research》1978,39(3):527-528

Ninety-six Hereford heifers (approximately 7 months of age) were randomly divided into 2 equal groups and housed 1.6 km apart (with 2 replications in time, 1 year apart). At 15 months of age, 1 group/replicate was inoculated with parainfluenza-3 virus, and the other group was given virus-free spent culture medium. Twenty-four hours later, 2 virgin bulls (2 years old) were placed with each group (24 cows) for natural breeding. Viral inoculation caused a twofold increase in parainfluenza-3 titer and a 0.3 C body temperature increase. There was no effect recognized from the virus on natural breeding efficiency.  相似文献   

Indirect solid-phase microradioimmunoassay for detection of pseudorabies virus antibody in swine sera.     

C L Kelling  W L Staudinger  M B Rhodes 《American journal of veterinary research》1978,39(12):1955-1957

An indirect solid-phase microradioimmunoassay (IRIA) was developed for detection and quantitation of antibodies to pseudorabies virus (PRV) in swine serum. Qualitative results of the IRIA compared closely with results of the serum neutralization test (NT) and the microimmunodiffusion test (MIDT). The IRIA was more sensitive than the NT for detection of antibodies to PRV in swine serum. The IRIA result is expressed numerically. With the IRIA and NT, antibody to PRV was first detectable in 3 experimentally infected pigs at 9 days after inoculation. With MIDT, antibody was detected in the 3 experimentally infected pigs at 9 days after inoculation. With the MIDT, antibody was detected in the 3 experimentally infected pigs at 7, 8, and 9 days after inoculation. The IRIA results are obtainable within a few hours; the NT and MIDT require 48 hours for completion.  相似文献   

Effect of the proteinase inhibitor aprotinin in the management of hemorrhagic shock in the dog.     

G D Bottoms  G L Coppoc  O F Roesel  B Wilcock  W Weirich 《American journal of veterinary research》1978,39(6):1023-1026

Aprotinin, a proteinase inhibitor, was evaluated as a pharmacologic aid in dogs subjected to lethal hemorrhagic shock. Survival time, hemodynamic changes, and plasma enzyme analysis were measured as criteria for drug effects. Mixed-breed dogs (n = 14) were divided into 2 groups of 7 each: nontreated dogs in shock (group 1) and aprotinin-treated dogs in shock (group 2). One of 7 dogs in group 1 and 2 of 7 dogs in group 2 survived. Survival time, for the remaining dogs in group 1 (190 min, n = 6) and group 2 (188 min, n = 5) were not significantly different. There was no significant difference in mean arterial pressure, mean pulmonary arterial pressure, cardiac output, or left ventricle systolic pressure associated with aprotinin treatment at any time after hemorrhagic shock. There was no significant difference in plasma lactic acid, aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, alpha-amylase, and beta-glucuronidase associated with treatment at any time; however, there were significant (P less than 0.05) increases with time. The gastrointestinal tract was the site of most obvious lesions found at necropsy. Lesions varied considerably in extent and severity without apparent correlation to the treatment regimen. These experiments did not show beneficial effects of aprotinin in dogs subjected to hemorrhagic shock, but neither did they completely rule out some valuable actions that may have been obscured by the type of model used.  相似文献   

An invasive procedure for in utero fetal electrocardiology: recording of fetal electrocardiograms by applying electrodes through the uterus.     

H B Williams  J S Rankin  R L Hamlin 《American journal of veterinary research》1978,39(1):183-184

An in utero technique was developed that allows direct access to the canine fetus for experimentation. This procedure reduces the need for fetal manipulation and umbilical blood flow compromise and reduces fetal fluid loss. In pregnant bitches, uterine horns could be delivered through a ventral midline incision. By manipulating the fetal membranes, and positioning the fetuses through them, electrodes could be inserted subcutaneously in the fetuses. Electrocardiograms satisfactory for interpretation were obtained from as many as 4 fetuses in a bitch for periods up to postoperative week 3.  相似文献   

Rapeseed meals in broiler diets: Effect on performance and sensory evaluation of carcasses     

W. J. Yule  R. L. McBride 《British poultry science》1978,19(4):543-548

1. The effect of including rapeseed meal (RSM) in lieu of soyabean meal in broiler diets was determined.

2. Live‐weight gains, from 8 to 63 d, were depressed when the diet contained 150 g RSM/kg and there was a highly significant negative correlation between weight gain and inclusion rate of RSM over this period.

3. The efficiency of food utilisation was worse when the diet included 150 g solvent RSM/kg than when it contained no RSM: food efficiency was consistently poorer whenever RSM was included in the diet but the difference was significant only when the diet contained 10 g tallow/kg.

4. Carcasses from birds fed on diets containing 10 g tallow/kg had a better appearance than those from birds on diets containing 30 g tallow/kg, while the flavour of meat from birds fed on a diet containing 150 g solvent RSM/kg treatment was adversely affected. However, up to 100 g solvent RSM/kg may be included in broiler diets without affecting appearance, taste, texture or acceptability of the meat.

5. Inclusion of 50 g or more, solvent RSM/kg reduced growth rate and worsened food efficiency.  相似文献   

Electrophoresis of avian muscle proteins     

Caroline C. L. Wilkinson  J. M. Jones 《British poultry science》1978,19(2):243-247

1. The electrophoretic patterns of water‐soluble proteins of avian muscle showed differences due both to species and to muscle type.

2. Each muscle pattern within a species showed a unique protein band which distinguished that species from other species.  相似文献
