Abstract
BackgroundRuminant mycoplasmoses are important diseases worldwide and several are listed by the World Organization for Animal Health to be of major economic significance. In France the distribution of mycoplasmal species isolated from clinical samples collected from diseased animals upon veterinary request, is monitored by a network known as VIGIMYC (for VIGIlance to MYCoplasmoses of ruminants). The veterinary diagnostic laboratories collaborating with VIGIMYC are responsible for isolating the mycoplasmas while identification of the isolates is centralized by the French Food Safety Agency (AFSSA) in Lyon. The VIGIMYC framework can also be used for specific surveys and one example, on the prevalence of M. bovis in bovine respiratory diseases, is presented here.ResultsBetween 2003 and 2008, 34 laboratories were involved in the network and 1904 mycoplasma isolates, originating from the main ruminant-breeding areas, were identified. For cattle, the high prevalence of M. bovis in bronchopneumonia, notably in young animals, was confirmed by VIGIMYC and an associated specific survey, whereas the non-emergence of species such as M. alkalescens and M. canis was also demonstrated. The etiological agent of bovine contagious pleuropneumonia was never isolated. The principal mycoplasmosis in goats was contagious agalactia with M. mycoides subsp. capri as main agent. Ovine mycoplasmoses, most of which were associated with pneumonia in lambs, were infrequently reported. One exception was ovine contagious agalactia (due to M. agalactiae) that has recently re-emerged in the Pyrénées where it had been endemic for years and was also reported in Corsica, which was previously considered free.ConclusionsAlthough VIGIMYC is a passive network and somewhat biased as regards sample collection and processing, it has provided, in this study, an overview of the main mycoplasmoses of ruminants in France. The French epidemiological situation is compared to those existing elsewhere in the world.

As a general rule 1) the number of mycoplasmal cultures received at AFSSA differs from the number of strains identified, this corresponding to a balance between samples containing several strains and negative samples; 2) each outbreak can be represented by one or several cultures as a function of its importance; and 3) each diseased wildlife animal was considered as an outbreak per se
M. dispar is potentially pathogenic for cattle [32] but cannot be grown on the culture media commonly used in laboratories, neither can M. capricolum subsp. capripneumoniae (Mccp), the etiological agent of contagious caprine pleuropneumonia (CCPP), a disease currently absent from France
Summary
Ruminant mycoplasmoses are important diseases worldwide and several are listed by the World Organization for Animal Health to be of major economic significance. In France the distribution of mycoplasmal species isolated from clinical samples collected from diseased animals upon veterinary request, is monitored by a network known as VIGIMYC (for VIGIlance to MYCoplasmoses of ruminants). Capricolum (Mcc) and M. putrefaciens mainly affect goats Another mycoplasmosis in cattle, in which M. bovis is the causal agent, is not on the OIE list but is considered to intensify concomitantly with animal production and international trade. In which M. bovis is the causal agent, is not on the OIE list but is considered to intensify concomitantly with animal production and international trade It is associated with a variety of clinical expressions [10], notably infectious bronchopneumonia (IBP) in young animals, as previously reported in France [11] and several other countries [12,13,14,15,16]
