| Sumari: | Leptospirosis and brucellosis are important zoonotic diseases worldwide with high
incidence in tropical countries affecting biodiversity, human and livestock health, animal
welfare and the economy (OIE, 2014; WHO, 2011). The expanding human population
along with rapid urbanization have increased the likelihood of wildlife and human
interaction. In Malaysia, the increased human-macaque conflicts (Hambali, 2012) have
resulted in the concern about zoonotic disease transmission. This study was conducted to
determine the seroprevalence of leptospirosis and brucellosis in wild long-tailed
macaques of Peninsular Malaysia. A hundred serum samples were screened for
antibodies against Leptospiraand Brucella using microscopic agglutination test (MAT)
and Rose Bengal Plate test (RBPT) respectively. Fourteen percent of macaques were
seropositive for leptospirosis with serovar Cellodoni(4%), and Pyrogenes (4%) as the
most common serovar identified, followed by Icterohaemorrhagiae (3%), Bataviae(2%) and Lai(1%). The prevalence in males were significantly higher than females. Males
were 4.5 times more likely to be seropositive for leptospirosis compared to females. This
suggests that sex differences in behaviour influences exposure of macaques to
leptospirosis. There were no significant difference in seroprevalence with age, habitat
and region. All samples were seronegative for brucellosis. This study concludes that
leptospirosis are prevalent in long-tailed macaques and poses a public health risk of
cross-species transmission. |
