Abstract
SOTO PRIANTE, Ernesto; LEMUS FLORES, Clemente and ORTIZ MUNIZ, Ariel. First isolation and identification of Ureaplasma spp and Mycoplasma lipofaciens in commercial hens in Mexico. Rev. mex. de cienc. pecuarias [online]. 2011, vol.2, n.1, pp.85-92. ISSN 2448-6698.
During a study carried out in Mexico in 2003 and 2004, both Ureaplasma spp and Mycoplasma lipofaciens were isolated from the upper trachea of live, healthy commercial White Leghorn (Gallus gallus domesticus) birds. In total 13 U. spp and 8 M. lipofaciens isolates were identified among the 223 Mycoplasmas isolated. U. spp was isolated from one single farm located in the state of Jalisco, housing 50-wk-old hens. M. lipofaciens was isolated from several farms in the States of Jalisco and Puebla, including 50-80 wk-old birds. This is the first report about the isolation and identification of both U. spp and M. lipofaciens in Mexico. This can be considered relevant since Ureaplasmas can be of avian or human origin, so that determining the potential interspecies transmission is required. In addition, M. lipofaciens yields positive reactions when serological tests for M. synoviae are performed, which can result in diagnostic errors and unnecessary treatments.
