Abstract
In 2008, 102 rodents and 24
stray cats from the areas around 9 pig farms in northeast South Korea were used to
determine the prevalence of the following selected swine pathogens: ten viral pathogens
[porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV),
rotavirus, classical swine fever virus (CSFV), porcine circovirus type 2 (PCV2),
encephalomyocarditis virus (EMCV), porcine reproductive and respiratory syndrome virus
(PRRSV), porcine parvovirus (PPV), pseudorabies virus (PRV) and Japanese encephalitis
virus (JEV)] and four bacterial pathogens (Brucella,
Leptospira, Salmonella and Lawsonia
intracellularis). In total, 1,260 tissue samples from 102 rodents and 24 stray
cats were examined by specific PCR and RT-PCR assays, including tissue samples of the
brain, tonsils, lungs, heart, liver, kidneys, spleen, small intestine, large intestine and
mesenteric lymph nodes. The percentages of PCR-positive rodents for the porcine pathogens
were as follows: 63.7% for Leptospira, 39.2% for
Brucella, 6.8% for Salmonella, 15.7% for L.
intracellularis, 14.7% for PCV2 and 3.9% for EMCV. The percentages of
PCR-positive stray cats for the swine pathogens were as follows: 62.5% for
Leptospira, 25% for Brucella, 12.5% for
Salmonella, 12.5% for L. intracellularis and 4.2% for
PEDV. These results may be helpful for developing control measures to prevent the spread
of infectious diseases of pigs.
