“…There were abscesses in the lung and liver, fibrinosuppurative pleuritis, polyarthritis, and disseminated microabscesses in various organs [42]. A similar disease was reported from North Dakota (USA), where necrotic pharyngitis associated with M. bovis infection occurred in American bison [43].…”

The biology, epidemiology and pathology of sucking louse infestation and Mycoplasma infection of water buffalo (Bubalus bubalis) herds in Hungarian national parks were studied between 19 December 2011 and 4 May 2012. A total of 333 water buffaloes were examined in buffalo stocks of the Balaton Uplands, Fertő-Hanság and Kiskunság National Parks. The objective was to determine the prevalence and rate of sucking louse infestation and mycoplasma infection among water buffaloes. Always an area of identical size (2 cm 2 ) was examined on the right or left side of the middle part of the animals' neck. A total of 3106 eggs, 10 nymphs and 105 adults of the sucking louse Haematopinus tuberculatus were identified with the help of a Conrad USB microscopic camera and a Wild-Leitz-Leica M420 photomacroscope. The data were evaluated using the Quantitative Parasitology software QP 3.0. The prevalence of mycoplasmas was determined in 20 randomly selected buffaloes of two national parks with the help of sterile nasal and vaginal transport swabs (Sarstedt). All of the 10 nasal swabs collected from buffaloes in the Balaton Uplands National Park contained Mycoplasma bovirhinis and three swab samples yielded M. bovis as well. Mycoplasma bovirhinis was cultured from 8 out of 10 swabs taken from the vagina, and three vaginal samples also yielded M. bovis. Similar results were obtained by testing samples collected from buffaloes in the Kiskunság National Park (Mórahalom). All ten nasal swab samples yielded M. bovirhinis. From two samples a mixture of M. bovirhinis and M. bovis was cultured. Nine out of the 10 vaginal swabs yielded M. bovirhinis while two showed a combined infection by M. bovis and M. bovirhinis.

“…M. bovis as a primary pathogen in bison is in contrast to M. bovis in adult cattle, where the bacterium tends to occur most commonly as 1 component of chronic, polymicrobial respiratory disease (24,27). The pronghorn M. bovis infection is more analogous to mycoplasmosis in bison, where it is known to be a primary cause of pneumonia, arthritis, pharyngitis, and reproductive disorders (6)(7)(8).…”

T he bacterium Mycoplasma bovis is an economically important pathogen of cattle that contributes to the multifactorial bovine respiratory disease complex. In addition to causing respiratory disease, this bacterium can cause polyarthritis, mastitis, otitis media, and a chronic pneumonia-polyarthritis syndrome, impacting beef and dairy cattle worldwide (1). Despite increased recognition of its role in economic loss in the cattle industry, M. bovis remains a clinical challenge because of a common carrier state in clinically healthy animals, variable disease expression, intermittent shedding, and the lack of rapid accurate diagnostic assays (1,2). Clinical disease is not considered necessary to maintain M. bovis in populations, and M. bovis is commonly detected in asymptomatic adult feedlot cattle (2). Although the upper respiratory tract mucosa is a primary site for M. bovis colonization, presence of the bacterium in the lung is variable in occurrence and clinical manifestation. In 1 study, M. bovis was detected in 46% of cattle with normal lungs, 82% of cattle with acute fibrinous pneumonia, and 98% of cattle with chronic pneumonia (3). Manifestation of M. bovis-associated respiratory disease is particularly common in the wake of stress (e.g., from transportation, comingling, feedlot entry, and harsh temperatures or conditions). In the early 2000s, M. bovis caused several highmortality (case-fatality rate 45%) epizootics in bison (Bison bison) in North America (4). These events raised concern about emergent virulent strains, and research began to characterize isolates from different host species (5). An important difference between outbreaks of mycoplasmosis in bison and cattle is that, in the former, few or no co-infecting bacterial or viral pathogens are consistently detected (4,6-8). Although M. bovis virulence factors are poorly defined, evasion of immune response is implicated in maintaining chronic infection (9). One study found that that up to 79% of bison herds in western Canada have >1 M. bovis-seropositive animal and that 8 of 11 herds with no history of M. bovis disease had seropositive animals (10). These findings suggest that host response to M. bovis varies; some exposed bison become subclinical carriers and might also

“…It has not generally been considered a significant infectious disease threat to bison, with only occasional anecdotal reports of outbreaks of pneumonia. In recent years, however, there have been alarming increases not only in the incidence and severity of M. bovis-associated infections in bison but also in the variety of clinical presentations, which currently include pneumonia, polyarthritis, pharyngitis, placentitis, and abortion (2)(3)(4)(5). Particularly of concern is the observation that M. bovis, which typically is a secondary or tertiary pathogen, appears to be acting as a primary pathogen in bison.…”

Mycoplasma bovis has recently emerged as a significant and costly infectious disease problem in bison. A method for the detection of M. bovis-specific serum antibodies is needed in order to establish prevalence and transmission patterns. Enzyme-linked immunosorbent assays (ELISAs) validated for the detection of M. bovis-specific serum IgG in cattle are commercially available, but their suitability for bison sera has not been determined. A collection of bison sera, most from animals with a known history of infection or vaccination with M. bovis, was tested for M. bovis-specific IgG using commercially available kits as well as an inhouse ELISA in which either cattle or bison M. bovis isolates were used as a source of antigen. Comparison of the results demonstrates that ELISAs optimized for cattle sera may not be optimal for the identification of bison seropositive for M. bovis, particularly those with low to moderate antibody levels. The reagent used for the detection of bison IgG and the source of the antigen affect the sensitivity of the assay. Optimal performance was obtained when the capture antigen was derived from bison isolates rather than cattle isolates and when a protein G conjugate rather than an anti-bovine IgG conjugate was used for the detection of bison IgG.
