Dominant Factors Influencing Leptospira Sp Infection in Rat and Suncus
Background: Mice and suncus may transmit leptospirosis. Each type mice and suncus had different habitat, among other, types, regions, and altitude. The purpose of this study to analyze the effect of altitude, variety of species, soil type, land use and flood against Leptospira sp infection in mice and sucus.
Methods: A cross-sectional study conducted at several locations in April-November 2011 in Central Java (the town and district of Semarang, district of Demak, district of Sleman and Wonogiri). Mice and suncus caught were identified, kidney were taken for the existence of bacteria leptospira by Polymerase Chain Reaction (PCR). To identify factors affecting leptosira sp infection, analysis of data using relative risk approach.
Results: Species of rats and suncus, elevation level, soil types and area related to risk Leptospira sp infection. Compared with S. murinus, Rattus norvegicusspecies had almost 78-fold to be Leptospira sp infected (adjusted relative risk ratio (RRa = 77.87; P = 0.001], and R. tanezumi had less risk (RRa = 7.95; P = 0.048). In term of elevation level, Lower elevation level (0-100 m) compared with higher level (101-600 m) had 2.3-fold risk to be Leptospira sp infection (RRa = 2.27; P = 0.132).
Conclusion: Species of rats and suncus, elevation level, soil types and area related to risk Leptospira sp infection. (Health Science Indones 2012;2:xx-xx)
