Abstract

The porcine circovirus type 2 (PCV2) is commonly present along with the porcine reproductive and respiratory syndrome virus (PRRSV). These are the most important pathogens for pig industry worldwide. In this study, we determined frequencies for both viruses, as well as coinfection, in farrow to finish farms from México. For this, pigs from 28 farms in different states were sampled for tonsils, lungs and lymphatic nodes and assayed for PCV2 and PRRSV by polymerase chain reaction (PCR) and reverse transcription-polymerase chain reaction (RT-PCR). Herds detected positive were: 16 PCV2 (57%), 10 PRRSV (36%); and 5 had both viruses (18%). Samples detected positives were: 49% PCV2, and 39% PRRSV. Coinfection frequency observed in this work contrasted those observed in other countries. We think that these data will contribute to a better understanding of both diseases in order to take better measures for preventing and controlling them.

Key words: Laboratory diagnosis, viral frequency, viral coinfection, PCV2, PRRSV, farrow to finish farm.
