Use of a standard kit for the diagnosis of respiratory viral infections in pigs.
Proceedings of the 4th International Symposium on Emerging and Re-emerging Pig Diseases, 2003, 268-269
A standard kit for the diagnosis of viral pathogens involved in acute respiratory disorders in pigs in the fields.The kit allowed the practicioner to take nasal swabs and blood sample at the first visit and another blood sample on the same pigs (ear tagged) one month later. Different diagnosis methods focused on PRRS, ADV and SIV were applied, including PCR, virus isolation in cells and eggs and serology depending on the pathogen. SIV was found to be a player in 12 out of t a total of 15 cases and in 9 out of 12 the virus was evidenced using a virological method. On the contrary, PRRS was found only twice by PCR in the swabs and 3 times by seroconversion. It is concluded that Flu is dramatically underestimated in acute respiratory episodes occuring in Italy.
