HARO TIRADO, Mario Enrique et al. Detection of pathogens of epidemiological importance in feral pigs from Chihuahua and Durango, Mexico. Rev. mex. de cienc. pecuarias [online]. 2023, vol.14, n.4, pp.915-922. Epub 17-Nov-2023. ISSN 2448-6698. https://doi.org/10.22319/rmcp.v14i4.6501.
This study aimed to evaluate in feral pigs the presence of Salmonella spp (Spp), porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), swine influenza virus (SIV), porcine epidemic diarrhea virus (PEDV), Mycoplasma hyopneumoniae (Mhyo) and Actinobacillus pleuropneumoniae (App). The samples were obtained from pigs in the states of Chihuahua and Durango, Mexico. The tests analyzed for the animals from Chihuahua were nasal swabs for SIV, rectal swabs for Spp and PEDV, serum for PRRSV and PCV2, lung, liver, and lymph nodes for Spp, SIV, PRRSV, and PCV2, as well as serum for serological tests. From animals in the state of Durango, the following was collected: nasal swabs for SIV, rectal swabs for Spp and PEDV, and serum for PCV2 for molecular and serological studies. The molecular results in both states showed samples positive for PCV2, 73.3 % in Chihuahua and 91.3 % in Durango; likewise, two positive samples were obtained for Spp in the state of Chihuahua (13.3 %) and one in Durango (6.6 %), for SIV there were two positive (8.7 %) in Durango. For PRRSV and PEDV, samples were negative in both states. Serological results in pigs from the two states showed positivity for PCV2, Spp, and App. Samples were negative for PRRSV, PEDV, and Mhyo in both states. It is important to highlight the molecular and serological detection of feral pigs positive for various infectious agents important in pig production with zoosanitary repercussions on public health, which implies an epidemiological relevance of these animals in the context of “one health”.
