| mycoplasma species recovered from the reproductive tracts of western canadian cows. | samples of cervico-vaginal mucus from 633 animals from 110 herds were cultured and yielded the following mycoplasmas: t-strain--88: mycoplasma bovigenitalium--79, mycoplasma spp. (leach group 7)--7, acholeplasma laidlawii--4, mycoplasma bovirhinis--2 and one not typable. uterine exudates and endometrial scrapings from 80 infertile cows in two herds were examined. four animals were positive, m. bovigenitalium was isolated three times, a. laidlawii and mycoplasma arginini once each. sixty-five nor ... | 1975 | 1125831 |
| porcine hemophilus parahemolyticus pneumonia in saskatchewan. ii. bacteriological and experimental studies. | the incidence of porcine pleuropneumonia caused by hemophilus parahemolyticus has shown a marked increase in recent years in some countries. isolation of a strain distinct from european serotypes was made from a natural outbreak of the disease in pigs in saskatchewan. experimentally infected pigs did not develop clinical signs but pathologic-anatomic studies of lungs revealed the presence of necrotizing fibrinous pneumonia with intense proliferation of mesenchymal tissue elements. similar extens ... | 1974 | 4274816 |
| porcine hemophilus parahemolyticus pneumonia in saskatchewan. i. natural occurrence and findings. | an outbreak of fibrinous pleuropneumonia was observed in october 1971 in saskatchewan on a farm of 900 feeder pigs. morbidity and mortality were low. pathologic-anatomic findings included fibrinous pleuritis, pulmonary vascular thrombosis and necrotizing fibrinous pneumonia. hemophilus parahemolyticus was isolated from the lungs of affected animals. in addition pulmonary lesions were found which suggested an adenovirus infection. it was speculated that the viral infection possibly predisposed th ... | 1974 | 4274828 |
| an abattoir survey of the incidence of pneumonia in saskatchewan swine and an investigation of the microbiology of affected lungs. | the lungs of 15 409 pigs, mostly from saskatchewan, slaughtered at an abattoir were examined over a one year period. the incidence of lesions was 36.7% for "enzootic" pneumonia and 2.1% for pleurisy unassociated with pneumonia. seasonal variations were recorded and compared with the results of similar surveys carried out in australia, belgium and england. mycoplasmological examination of lungs from 347 animals was consistently negative for mycoplasma hyopneumoniae. pasteurella multocida was the ... | 1981 | 7248880 |
| a survey of skeletal disorders in five turkey flocks in saskatchewan. | losses due to skeletal disorders varied from 1.8 to 6.1 percent in five flocks, varying in size from 2040 to 7033 birds, of broad breasted white tom turkeys. very little evidence of significant air-sacculitis due to mycoplasma meleagridis was found in hatching poults or during the growing period. major disorders causing the losses included rickets, rotated tibia, arthritis/osteomyelitis and long bone distortion. rickets and arthritis/osteomyelitis due to infection with staphylococcus aureus were ... | 1980 | 7427775 |
| epidemiological study of enzootic pneumonia in dairy calves in saskatchewan. | a field study involving 325 calves from 17 dairy herds in saskatchewan was conducted to determine the risk of enzootic pneumonia and to assess its association with a number of factors. two different case definitions of pneumonia were used in the analyses: the first was based on producers' treatment risk (case1) and the second was based on semimonthly clinical examinations of calves by the research veterinarian (case2). the risk of pneumonia based on case1 was 39% and on case2 was 29%. the measur ... | 1993 | 8269363 |
| survey of mycobacterium avium subspecies paratuberculosis serological status in beef herds on community pastures in saskatchewan. | johne's disease is a well recognized problem in dairy herds. relatively little information is available on either the prevalence or the control of johne's disease in commercial cow-calf operations. in the fall of 1999, blood samples were collected during pregnancy testing from cows on community pastures in saskatchewan. sera from these cows were analyzed using a commercial elisa for antibodies to mycoplasma avium subspecies paratuberculosis. all cows from each herd examined at the community past ... | 2002 | 12125186 |
| mycoplasma haemofelis and mycoplasma haemominutum detection by polymerase chain reaction in cats from saskatchewan and alberta. | hemobartonellosis is caused by mycoplasma haemofelis, previously known as haemobartonella felis. cats infected with this organism typically develop regenerative anemia. the related species mycoplasma haemominutum may also cause anemia. the purposes of this study were to use polymerase chain reaction technology to determine if both organisms exist in naturally infected cats from saskatchewan and alberta, and to determine if disease manifestation corresponds to mycoplasma species. thirteen of 18 c ... | 2004 | 15510683 |
| hemotropic mycoplasma prevalence in shelter and client-owned cats in saskatchewan and a comparison of polymerase chain reaction (pcr) - results from two independent laboratories. | the primary objective of this study was to determine the prevalence of subclinical hemotropic mycoplasma (hm) infections in 2 distinct feline populations: cats from a local shelter and client-owned cats presented for elective procedures (vaccination, ovariohysterectomy, orchiectomy) at the western college of veterinary medicine - veterinary teaching hospital (wcvm-vth). the second objective of this study was to evaluate the inter-test agreement of 2 independent conventional polymerase chain reac ... | 2010 | 20592837 |
