BACKGROUND: Domestic animals are known to be either maintenance or accidental hosts of Leptospira. Determination of seroprevalence of leptospirosis among these animals is of great importance due to their close association with humans, economic loss as well as the public and veterinary health problems caused by the said zoonosis.

OBJECTIVE: This study aimed to determine the seroprevalence of leptospirosis among water buffaloes, pigs, and dogs in selected areas in the Philippines.

METHODS: Microscopic agglutination test (MAT) was used to test for leptospirosis. Testing was done from January 2007 to August 2008.

RESULTS: With the cut-off titer set at 1:80, the MAT-positivity rates were 82%, 67%, and 79% for 190 water buffaloes, 45 pigs, and 106 dogs, respectively. The most common prevailing serovars detected were Hardjo, Tarassovi, and Hebdomadis for water buffaloes; Semaranga, Grippotyphosa, and Patoc for pigs; and, Manilae, Patoc, and Autumnalis for dogs. MAT-positivity rates among these animals in terms of age (except for water buffaloes), sex and sample collection sites were not statistically significant. No Leptospira was isolated from the blood, urine, and kidney samples of these animals.

CONCLUSION: Results indicate a high seroprevalence of leptospirosis among the animals studied and that several pathogenic leptospires are causing infection in these animals.

In this study, we examine prevalences of three infectious pathogens with different transmission modes (Bartonella henselae, hemoplasma, and Toxoplasma gondii) in feral cats from urban and rural habitats. Infection status of the three pathogens in blood samples (n = 117) was determined through molecular or serological diagnostic methods. Overall prevalence of hemoplasma, Toxoplasma gondii, and Bartonella henselae was 47.9%, 50%, and 35.7%, respectively. Comparing the two habitats, only seroprevalence of Bartonella henselae was significantly higher in urban cats. Based on the results, we discuss how pathogens with distinct transmission modes may show different prevalence between urban and rural habitat types.

Proliferative enteropathy caused by Lawsonia intracellularis is one of the most common enteric diseases in pigs. The objective of this study was to determine the prevalence of serum antibodies against L. intracellularis in the general swine population of Korea from 2005 to 2008. In total, 8,008 swine serum samples obtained from 1,001 herds were tested. The samples were analyzed with an immunoperoxidase monolayer assay to detect anti-L. intracellularis antibodies. The overall 4-year average true prevalence was 40.0% (CI: 39.4 - 40.6%) at the individual animal level and 71.9% (CI: 70.3-73.4%) at the herd level.
