“…Other mycoplasmas isolated from cattle were, unless otherwise stated, from the lungs or upper respiratory tract, and included: Mycoplasma alkalescens (two isolates, one in 1997 and one in 1999); Mycoplasma alvi (three isolates, two in 1993 and one in 1994); Mycoplasma arginini (37 isolates between 1993 and 2000), one from an eye and one from milk; Mycoplasma bovigenitalium (eight isolates, three in 1995 and five in 2000), one in pleural fluid and five from vaginal swabs; Mycoplasma bovoculi (nine isolates, six in 1994, one in 1995 and two in 1997), one in milk, two not known; M canis (78 isolates), three in milk; Mycoplasma dispar (19 isolates); Mycoplasma gallinarum (one isolate from milk in 1991); Mycoplasma verecundum (three isolates, two in 1994 from a sheath washing and vaginal mucus, and one in 1999); Acholeplasma axanthum (three isolates, one from an eye in 1991 and two in 1996); Acholeplasma granularum (three in 1997), one from fetal gut; Acholeplasma modicum (two isolates, one in 1995 and one in 1998), one from an udder; and Acholeplasma oculi (one from a sheath washing in 1992). M canis was first isolated from cattle in the uk in 1995 (Nicholas and others 1995). The number of M canis isolations increased between 1995 and 2000, with one in 1995, two in 1996, 11 in 1997, 13 in 1998, 25 in 1999 and 26 in 2000 (Table 1).…”

Between 1990 and 2000, more than 1600 mycoplasmas and the related acholeplasmas were identified from ruminant animals by the Mycoplasma Group at the Veterinary Laboratories Agency--Weybridge. Mycoplasma bovis was the most commonly identified pathogen, mostly from pneumonic calves but occasionally from cattle with mastitis and arthritis. Mycoplasma canis was first isolated in Britain in 1995 from pneumonic calves and the number of isolates increased to 18 per cent of the total mycoplasmas isolated from cattle in 1999. The ELISA for antibodies to M. bovis detected 1971 positive samples (22 per cent) among 8959 serum samples, mainly from pneumonic cattle. Other mycoplasmas identified included Mycoplasma dispar from the lungs of cattle with respiratory disease, and Mycoplasma bovigenitalium from the reproductive tract of cows with vulvovaginitis and infertility. Mycoplasma bovirhinis and Acholeplasma species were found commonly but are thought to be more opportunistic than pathogenic. In sheep and goats, the majority of Mycoplasma species isolated were identified as Mycoplasma ovipneumoniae from pneumonic sheep, Mycoplasma conjunctivae from sheep with keratoconjunctivitis, and the ubiquitous Mycoplasma arginini.

“…M canis was isolated from 10.7 per cent of the samples which were examined for it, all in association with M dispar. M canis , which is mainly involved in canine urogenital infections (Doig and others 1981), has also been recorded from calves with respiratory disease in the Netherlands (ter Laak and others 1993a) and in the UK (Nicholas and others 1995). Evidence of its pathogenic potential in the bovine respiratory tract was recently provided by Nicholas and others (2000).…”

Isolation ofMycoplasmaspecies from the lower respiratory tract of healthy cattle and cattle with respiratory disease in Belgium

et al. 2002

Between 1997 and 2000, a total of 150 healthy cattle and 238 animals with respiratory disease were examined for six Mycoplasma species. Attempts were made to detect Mycoplasma canis, Mycoplasma dispar and Ureaplasma diversum in calves with recurrent disease, and all three of these species were identified in calves with recurrent disease and in healthy lungs. In healthy calves, 84 per cent of bronchoalveolar lavage fluids were mycoplasma free; when cultures were positive, Mycoplasma bovirhinis was the only species isolated. Mycoplasmas were isolated from 78 per cent of animals suffering recurrent respiratory disease and from 65 per cent of acute respiratory cases. Mycoplasma bovis was isolated from bronchoalveolar lavages from 35 per cent of calves suffering recurrent respiratory disease, and from 50 per cent of acute cases, and from 20 per cent of pneumonic cases examined postmortem. M bovis was associated with other Mycoplasma species in 44 per cent of cases. M dispar was also isolated from 45.5 per cent of calves suffering recurrent respiratory disease, often in association with M bovis. M canis was identified for the first time in diseased Belgian cattle. Other mycoplasmas, including Mycoplasma arginini, Mycoplasma alkalescens and U diversum, were isolated less frequently. Associations between mycoplasmas and other pathogens were often observed. Among lungs infected with Pasteurella and/or Mannheimia species, more than 50 per cent were mixed infections with M bovis.

“…canis has been isolated from cattle with respiratory disease by some researchers, but it is known primarily as a cause of reproductive disease in dogs (2,(4)(5)(6). In our study, M. canis was isolated and identified from two lung samples taken from calves in the same farm.…”

“…It was firstly isolated from pneumonic calves in Holland in 1993 (4). Isolations from calf pneumonia (5,6) and mastitis (29) were later reported. The most important means of M. canis transmission to cattle has been thought to be close contact with dogs, which are the primary hosts.…”
