摘要: There are evidences that wild boar and domestic pig populations share the vulnerability to certain pathogens and, in consequence, risk of pathogen transmission. Based on serological evidences, it is known Mycoplasma hyopneumoniae (Mhyo) able infect boar. However, if this infection causes lesions disease species still unknown. The objectives present study were assess seroprevalence Mhyo, as well rates detection Mhyo (by nested polymerase chain reaction, nPCR) upper lower respiratory tract Moreover, presence enzootic pneumonia (EP)-like gross microscopic these animals was also assessed. Antibodies against detected 92 out 428 (21%) serum samples tested. DNA by nPCR 17 85 (20%) nasal swabs 12 156 (8%) lung samples. No EP-like observed any studied pigs. Besides, 18 63 (29%) animals. at level 2 (11%) Presence significantly related (p 0.05) with its samples; such linked < Metastrongylus spp.-like parasite structures. Results confirm might be cause but, apparently, a subclinical impact.
