“…Despite this, our results suggest that the camels do not pose a potential risk of transmitting CA to the small ruminants. No other information is available on dromedaries but our results are partially consistent with the findings of Hung et al (1991) in South American camelids (alpacas, llamas and vicuñ as), who were unable to detect any serological reactants to M. agalactiae although their results revealed evidence of exposure to MmmLC.…”

“…Although slightly positive complement fixation tests (CFT) have been recorded from wildebeest and hippopotami (Shifrine and Domermuth, ), subcutaneous inoculation of live Mycoplasma did not induce any typical lesion as compared to control bovines inoculated in parallel, so these species are not likely natural hosts despite these findings. Positive complement fixation tests have been detected only in camels (Paling et al., ) but no mycoplasmas were isolated from nasal secretions from camels or buffaloes, which is similar to findings in American camelids (Hung et al., ). While CFT was performed with a crude antigen, it is highly probable that the positives were in fact cross‐reactors with other mycoplasmas or bacteria.…”

Contagious bovine pleuropneumonia has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on the eligibility of contagious bovine pleuropneumonia to be listed, Article 9 for the categorisation of contagious bovine pleuropneumonia according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species related to contagious bovine pleuropneumonia. The assessment has been performed following a methodology composed of information collection and compilation, expert judgement on each criterion at individual and, if no consensus was reached before, also at collective level. The output is composed of the categorical answer, and for the questions where no consensus was reached, the different supporting views are reported. Details on the methodology used for this assessment are explained in a separate opinion. According to the assessment performed, contagious bovine pleuropneumonia can be considered eligible to be listed for Union intervention as laid down in Article 5(3) of the AHL. The disease would comply with the criteria as in Sections 4 and 5 of Annex IV of the AHL, for the application of the disease prevention and control rules referred to in points (d) and (e) of Article 9(1). The animal species to be listed for contagious bovine pleuropneumonia according to Article 8(3) criteria are species of the family Bovidae as susceptible.

“…mycoides large-colony are exceptional because strains of each have been shown to infect goats, sheep, and cattle, and titers of antibody against M. mycoides subsp. mycoides large-colony have been found in other animals (8,14,37). The high degree of host fidelity previously ascribed to other members of the mycoides cluster may have been due to a lack of extensive sampling from different ruminant species or the use of relatively insensitive culture techniques (41).…”

In the winter of 2002, an outbreak of mycoplasma infection in Vaal rhebok (Pelea capreolus) originating from South Africa occurred 15 weeks after their arrival in San Diego, Calif. Three rhebok developed inappetence, weight loss, lethargy, signs related to pulmonary or arthral dysfunction, and sepsis. All three rhebok died or were euthanized. Primary postmortem findings were erosive tracheitis, pleuropneumonia, regional cellulitis, and necrotizing lymphadenitis. Mycoplasmas were detected in numerous tissues by electron microscopy, immunohistochemistry, and PCR. The three deceased rhebok were coinfected with ovine herpesvirus-2, and two animals additionally had a novel gammaherpesvirus. However, no lesions indicative of herpesvirus were seen microscopically in any animal. The rheboks' mycoplasmas were characterized at the level of the 16S rRNA gene, the 16S-23S intergenic spacer region, and the fructose biphosphate aldolase gene. Denaturing gradient gel electrophoresis was carried out to address the possibility of infection with multiple strains. Two of the deceased rhebok were infected with a single strain of Mycoplasma capricolum subsp. capricolum, and the third animal had a single, unique strain most closely related to Mycoplasma mycoides subsp. mycoides large-colony. A PCR survey of DNA samples from 46 other ruminant species demonstrated the presence of several species of mycoplasmas in the mycoides cluster, including a strain of M. capricolum subsp. capricolum identical to that found in two of the rhebok. These findings demonstrate the pervasiveness of mycoplasmas in the mycoides cluster in small ruminants and the potential for interspecies transmission and disease when different animal taxa come in contact.Mycoplasmas of the mycoides cluster are pathogens of ruminants and comprise six closely related species that are subdivided into two subgroups based on genetic similarity. The capricolum subgroup includes Mycoplasma capricolum subsp. capricolum, Mycoplasma capricolum subsp. capripneumoniae, and Mycoplasma subsp. bovine group 7 (BG7). The mycoides subgroup consists of Mycoplasma mycoides subsp. capri, Mycoplasma mycoides subsp. mycoides small-colony, and Mycoplasma mycoides subsp. mycoides large-colony (45). All six species of the mycoides cluster can cause respiratory, arthral, genitourinary, or mammary disease, although significant hostand strain-related variation in virulence exists. M. mycoides subsp. mycoides small-colony and M. capricolum subsp. capripneumoniae, the etiologies of contagious bovine pleuropneumonia (CBPP) and contagious caprine pleuropneumonia (CCPP), respectively, are the most virulent and typically induce fatal systemic disease in their hosts. Other members of the mycoides cluster, while pathogenic, do not usually cause life-threatening illness and, instead, establish protracted infections that result in low levels of chronic inflammation (8, 37).Infection of sheep and goats with mycoplasmas in the mycoides cluster occurs worldwide. The insidious nature of many of these infections al...
