Dominant factors influencing leptospira sp infection in rat and suncus

Abstract


Abstrak

Latar belakang: Tikus dan cecurut dapat menularkan leptospirosis. Setiap jenis tikus dan cecurut mempunyai habitat masing-masing, antara lain jenis, daerah, dan ketinggian. Tujuan penelitian ini untuk menganalisis pengaruh ketinggian, variasi spesies, jenis tanah, tata guna lahan, dan banjir terhadap infeksi Leptospira sp pada tikus dan cecurut.

Metode: Penelitian potong lintang dilakukan di beberapa lokasi pada bulan April-November 2011 di Jawa Tengah (kota dan kabupaten Semarang, kabupaten Demak, kabupaten Sleman dan Wonogiri). Tikus dan cecurut yang tertangkap diidentifikasi, dan diambil ginjal untuk diperiksa keberadaan bakteri leptospira dengan Polymerase Chain Reaction (PCR). Untuk mengidentifikasi faktor yang mempengaruhi infeksi leptosira sp pada tikus, analisis data memakai pendekatan risiko relatif.

Hasil: Spesies tikus dan cecurut, tingkat elevasi dan jenis tanah berpengaruh terhadap risiko infeksi Leptospira sp. Dibandingkan dengan S. murinus, Rattus norvegicus spesies hampir 78 kali lipat berisiko infeksi Leptospira sp (risiko relatif rasio suaian (RRa = 77.87, P = 0,001], dan R. tanezumi memiliki risiko yang lebih rendah (RRa = 7,95, P = 0,048). Menurut tingkat elevasi tanah, elevasi yang rendah (0-100 m) dibandingkan dengan yang lebih tinggi (101-600 m) berisiko 2,3 kali lipat terinfeksi Leptospira sp (RRa = 2,27, P = 0,132).

Kesimpulan:Infeksi leptospirosis pada tikus berkaitan dengan species tikus dan cecurut serta tingkat elevasi serta jenis tanah. (Health Science Indones 2012;2:xx-xx)

Kata kunci:species tikus dan cecurut, leptospirosis

Abstract
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)
