The objective of this work was to detect the presence of three main pig respiratory viral agents
(porcine rubulavirus [PorPV], porcine circovirus type 2 [PCV-2], and porcine reproductive and
respiratory syndrome virus [PRRSV]) in tissues of emaciated piglets from the Bajío Region
(Mexico). Necropsies and histopathological studies of 37 pigs with poor body condition were
performed; viruses were detected by molecular biology methods and PCV-2 was further assessed
by immunohistochemistry (IHC). Histopathologically, interstitial pneumonia was observed in
25/37 (68%) of the piglets. Also, a varying degree of lymphocyte depletion in lymphoid organs
was found in 14/37 (38%) animals. Through polymerase chain reaction (PCR) and/or reverse
transcription polymerase chain reaction (RT-PCR), from the 37 pigs, 16 were positive for PCV-2,
18 for PRRSV and 1 for PorPV. In accordance with these results, the infection and/or co-infection
with PCV-2 and PRRSV were fairly frequent findings in piglets with poor body condition in
Mexico, while the infection by PorPV was apparently negligible. Wasting of post-weaning piglets
is a global pig farming problem that causes great economic losses and has been associated with
diverse factors: microbial agents, environmental factors, nutritional factors, and management.
When the Blue Eye Disease was first reported in Mexico, it was associated with severe wasting
in post-weaning piglets. This study demonstrated that this disease does not seem to play such an
important role in the wasting as was previously thought.
