| antibodies against mycoplasma bovigenitalium in free-living european bison (bison bonasus) with balanoposthitis. | since 1980 severe chronic balanoposthitis has been observed in free-living european bison (bison bonasus) in the białowieza primeval forest (poland). sera of 50 bison with balanoposthitis and 48 clinically healthy male and 49 female bison were investigated for antibodies against mycoplasma bovis and m. bovigenitalium by western blot analysis. prevalence of antibodies against m. bovigenitalium was significantly higher in bison with balanoposthitis than in unaffected male bison. mycoplasma bovigen ... | 2002 | 12528443 |
| an outbreak of chronic pneumonia and polyarthritis syndrome caused by mycoplasma bovis in feedlot bison (bison bison). | mycoplasma bovis was identified by a specific lesion, conventional bacterial culture, immunohistochemistry, and polymerase chain reaction in 2 feedlot bison found dead with severe, chronic, caseonecrotic pneumonia; polyarthritis; and laryngitis. on microscopic examination, pulmonary lesions were characterized by prominent, well-defined areas of caseous necrosis and bronchiectasis. immunohistochemical analysis of lung exhibited staining in bronchiolar epithelium and in random areas of caseous nec ... | 2008 | 18460630 |
| mycoplasma bovis outbreak in a herd of north american bison (bison bison). | a disease outbreak of high morbidity and high mortality in bison (bison bison) was investigated. clinical signs included lameness, swollen joints, respiratory distress, and lethargy. fifty-three of 194 animals died. cows between 5 and 10 years of age were the most affected group, in which 40 of 88 animals died. necropsies were performed on several animals. there were abscesses in the lung and liver, as well as fibrinosuppurative pleuritis, polyarthritis, and disseminated microabscesses in variou ... | 2010 | 20807947 |
| clinical presentation, prevalence, and risk factors associated with mycoplasma bovis-associated disease in farmed bison (bison bison) herds in western canada. | | 2017 | 28467749 |
| a serologic survey of mycoplasma spp. in farmed bison ( bison bison) herds in western canada. | mycoplasma bovis is emerging as an important pathogen of farmed bison in north america and is associated with high morbidity and mortality in affected herds. we developed an in-house elisa to detect antibodies against mycoplasma spp. in bison sera. the aims of the study were to estimate the seroprevalence against mycoplasma spp. in bison herds with or without past history of m. bovis-associated disease, and to determine potential risk factors for seropositivity to mycoplasma spp. in farmed bison ... | 2017 | 28578617 |
| necrotic pharyngitis associated with mycoplasma bovis infections in american bison (bison bison). | mycoplasma bovis has emerged as a significant and costly infectious disease problem in bison, generally presenting as severe, caseonecrotic pneumonia. three diagnostic cases in which m. bovis is associated with necrotic pharyngitis in bison are described in the current study. the bacterium was isolated from lesions of the pharynx or lung of 3 american bison (bison bison), at 2 different locations in the upper midwestern united states, with severe, necrotic pharyngeal abscesses. chronic caseonecr ... | 2013 | 23512925 |
| systemic mycoplasmosis with dystocia and abortion in a north american bison (bison bison) herd. | the current study describes a fatal mycoplasma bovis infection in a north american bison (bison bison) cow and her aborted fetus in a herd suffering unusual mortality associated with dystocia and abortion. postmortem evaluation of the subject case found severe caseonecrotic bronchopneumonia, chronic fibrinous pleuritis and pulmonary sequestra, foci of caseous necrosis in the kidneys, and necrotizing endometritis and placentitis. histologic findings in the maternal tissues include endometrial and ... | 2013 | 23847228 |
| a serological and molecular study on the occurrence of mycoplasmas in european bison (bison bonasus) from two areas of eastern poland. | european bison (bison bonasus) from two different areas of eastern poland showing gross pathology possibly associated with mycoplasma infections were tested for ruminant mycoplasma species using serological and molecular methods. fifty-five samples, blood or tissue were collected from 28 animals during 2013-2014. six sera were positive for mycoplasma bovis. the elisa and complement fixation test for mycoplasma mycoides subsp. mycoides gave a few weak reactions, but were negative by immunoblottin ... | 2015 | 26812834 |
| in vitro antimicrobial susceptibility of mycoplasma bovis clinical isolates recovered from bison (bison bison). | mycoplasma bovis is a pathogen globally affecting cattle and bison herds, causing pneumonia, arthritis, mastitis, abortions, and other symptoms, leading to huge economic losses. many studies have been done regarding the antimicrobial susceptibility of m. bovis isolated from cattle, but no such study is available for isolates recovered from bison. for the first time, in vitro susceptibilities of 40 m. bovis clinical isolates collected from bison herds in canada are reported here. minimal inhibito ... | 2016 | 26854525 |
| mycoplasma bovis isolates recovered from cattle and bison (bison bison) show differential in vitro effects on pbmc proliferation, alveolar macrophage apoptosis and invasion of epithelial and immune cells. | in the last few years, several outbreaks of pneumonia, systemically disseminated infection, and high mortality associated with mycoplasma bovis (m. bovis) in north american bison (bison bison) have been reported in alberta, manitoba, saskatchewan, nebraska, new mexico, montana, north dakota, and kansas. m. bovis causes chronic pneumonia and polyarthritis syndrome (cpps) in young, stressed calves in intensively-managed feedlots. m. bovis is not classified as a primary pathogen in cattle, but in b ... | 2016 | 27016754 |
| risk factors for mycoplasma bovis-associated disease in farmed bison (bison bison) herds in western canada: a case-control study. | north american bison producers have been attempting to control and prevent mycoplasma bovis-associated disease without the benefit of bison-specific knowledge. the objective of this study was to determine the clinical presentation of disease associated with m. bovis infection in western canadian farmed bison, and to identify herd-level risk factors for m. bovis-associated disease. bison producers (n=49) from western canada (manitoba, saskatchewan, alberta, and british columbia) were selected for ... | 2016 | 27317324 |
| serological studies to determine the occurrence of johne's disease and mycoplasma infection in the northern-east polish population of european bison (bison bonasus). | a serological study of twenty three european bison (bison bonasus) derived from northern-east poland for the seroprevalence of mycobacterium avium subsp. paratuberculosis, mycoplasma bovis, mycoplasma mycoides subsp. mycoides sc, mycoplasma agalactiae and mycoplasma capricolum subsp. capripneumoniae was conducted. only specific antibodies to m. bovis were detected in two animals (8.7%) which were connected with the clinical signs and macroscopic anatomopathological lesions. | 2014 | 25638988 |
| histophilosis as a natural disease. | histophilus somni is responsible for sporadic disease worldwide in cattle and, to a lesser extent, in small ruminants, bighorn sheep (ovis canadensis), and north american bison (bison bison). the importance of h. somni diseases can be attributed to improved clinical and laboratory recognition, combined with the growth in intensive management practices for cattle. although outbreaks of bovine histophilosis can occur year-round, in northern and southern hemispheres, it is most frequent in late fal ... | 2016 | 26847357 |
