| infectious agents in respiratory disease of housed, fattening lambs in northern ireland. | a two-year longitudinal, microbiological and pathological survey of respiratory disease in lambs housed for fattening at three-and-a-half to four months of age was undertaken. in the first year samples of nasal mucus and blood were taken from lambs each week for the first nine weeks after entry to a fattening unit and each week one lamb was examined post mortem. in the second year two additional fattening units were included in the survey, when samples of blood and nasal mucus were taken from la ... | 1988 | 3381463 |
| isolation of mycoplasmas from bovine semen in northern ireland. | in a survey of 332 fresh and 137 processed bovine semen samples and 25 preputial washes, mycoplasmas and, or, ureaplasmas were isolated from 46 per cent, 31 per cent and 80 per cent, respectively. intermittent isolation from different semen collections from the same bull indicated that at least three collections per bull were necessary to determine whether infection was present. when stored processed samples were examined mycoplasma canadense and m bovigenitalium were isolated from straws taken ... | 1987 | 3424585 |
| apparent reinfection of enzootic-pneumonia-free pig herds: search for possible causes. | in a control scheme for enzootic-pneumonia-free herds, run by the pig health control association, a detailed study was made of 55 herds that developed enzootic pneumonia without a simple explanation. these herds were compared with 57 herds that were still free from enzootic pneumonia in mid-1984. a high standard of precautions against the risk of infection being transferred by people and fomites seemed to confer no obvious benefit. this observation was in keeping with in vitro studies which show ... | 1985 | 4024433 |
| eradication of mycoplasma bovis infection from a dairy herd in great britain. | mycoplasma bovis infection was eradicated from a naturally infected dairy herd in great britain by a programme of identification, segregation and culling of infected animals. a series of group and whole milking herd tests was carried out over a period of 15 months, followed by a whole herd nasal swabbing. cows were also sampled after calving and at drying off and bulk tanks were sampled at weekly intervals during the same period and for a further nine months. fifty-nine cows were identified as e ... | 1983 | 6845609 |
| isolation of mycoplasma californicum from an outbreak of bovine mastitis and the experimental reproduction of the disease. | a mycoplasma-like organism was isolated from five cows with chronic incurable mastitis from one dairy herd. this organism was shown to be mycoplasma californicum and was used to infect three cows by intramammary inoculation. the challenge organism was reisolated from all the infected quarters and the ensuing inflammatory response produced a chronic mastitis with a permanent drop in milk yield. antibiotic treatment in one animal was unsuccessful. | 1982 | 7112877 |
