| incidence, location and interrelationships between the sites of abscesses recorded in pigs at a bacon factory in northern ireland. | the position and incidence of all the abscesses detected during post mortem inspection of 75,130 bacon weight pigs were recorded. abscesses were detected at one site only in 2.87 per cent of the carcases examined, and at more than one site in 0.26 per cent of the carcases. tail biting was the cause of the infection in 61.7 per cent of all the carcases with lesions at more than one site. in almost all cases there was a statistically significant interrelationship between the visible abscesses at d ... | 1996 | 8761973 |
| stillbirth/perinatal weak calf syndrome: a study of calves infected with leptospira. | leptospiral infection has been reported in calves which were either stillborn or dead from perinatal weak calf syndrome; 356 such calves were examined for evidence of associations between leptospiral infection and macroscopic, histological and microbiological findings, and the parity of the dam. calves in which leptospiral antigen was detected in the placenta were significantly lighter by an average of 6 to 10 kg than calves with no antigen in the placenta. calves infected with leptospira were m ... | 1999 | 10609569 |
| investigation of polymerase chain reaction assays to improve detection of bacterial involvement in bovine respiratory disease. | bovine respiratory disease (brd) causes severe economic losses to the cattle farming industry worldwide. the major bacterial organisms contributing to the brd complex are mannheimia haemolytica, histophilus somni, mycoplasma bovis, pasteurella multocida, and trueperella pyogenes. the postmortem detection of these organisms in pneumonic lung tissue is generally conducted using standard culture-based techniques where the presence of therapeutic antibiotics in the tissue can inhibit bacterial isola ... | 2014 | 25012080 |
