INDENTIFY OF SEROVAR THAT CAUSED CANINE LEPTOSPIROSIS IN YOGYAKARTA

AbstractLeptospirosis is a zoonotic disease of global concern, and is caused by pathogenic serovar Leptospire interrogans. Canine Leptospirososis is widespread throughout the world, dogs can act as incidental hosts or maintenance hosts for various serovars. The purpose of this reaserch was to identify leptospire serovars that infect healthy and suspected leptospirosis dogs in Yogyakarta. A total of 56 dogs (36 healthy dogs and 20 suspect leptospirosis dogs) were done blood collection from cephalica vein 3 ml, serum was separated for leptospirosis examination with Microscopic Aglutination Test (MAT) which conducted at the Research Center for Veterinary Science, Bogor. Microscopic Aglutination Test carried out on various Leptospire serovar, namely: Ichterohaemorrhagiae, Javanica, Celledoni, Ballum, Pyogenes, Cynopeteri, Rachmati, Auatralis, Pomona, Canicola, Grippotyphosa, Bataviae, Hardjo, and Tarrasovi. The results showed that Celledoni serovars infected 25% of healthy dogs and 5% of suspect leptospirosis dogs, Javanica serovar infected 19% of healthy dogs, Bataviae serovars infected 15% of suspect leptospirosis dogs, Grippotyphosa serovar infected 11% of healthy dogs, Tarrasovi serovar infected 10% of suspect leptospirosis dogs, serovars Cynopteri infects 5% of healthy dogs and 5% of suspect leptospirosis dogs, serovar Pyrogenes infects 5% of healthy dogs and 5% of suspect leptospirosis dogs, and serovar Rachmati infects 5% of suspect leptospirosis dogs. Seven healthy dogs (19%) and 2 suspect leptospirosis dogs (10%) were infected with more than 2 leptospire serovars. From the results of this study it can be concluded that Celledoni serovar of Leptospira interrogans infection causes subclinical leptospirosis, while Bataviae serovar infection causes clinical leptospirosis in dogs in Yogyakarta. Abstrak Leptospirosis adalah penyakit zoonosis yang menjadi perhatian global, dan disebabkan oleh serovar patogen Leptospira interrogans. Leptospirososis pada anjing tersebar luas di seluruh dunia, anjing dapat berperan sebagai incidental host ataupun maintenance hosts untuk berbagai serovar. Tujuan penelitian ini untuk mengidentifikasi serovar leptospira yang menginfeksi anjing sehat maupun anjing terduga leptospirosis di Yogyakarta. Penelitian ini menggunakan serum yang diambil dari 56 ekor anjing di Yogyakarta, yang terdiri dari 36 anjing tanpa gejala leptospirosis (sehat) dan 20 anjing dengan gejala leptospirosis (sakit). Serum dikoleksi untuk pemeriksaan Microscopic Agglutination Test (MAT) yang dilaksanakan di Balai Besar Penelitian Veteriner (BBLitvet), Bogor. Uji dilakukan terhadap 14 serovar Leptospira, yaitu: Ichterohaemorrhagiae, Javanica, Celledoni, Ballum, Pyogenes, Cynopeteri, Rachmati, Australis, Pomona, Canicola, Grippotyphosa, Bataviae, Hardjo, dan Tarrasovi. Hasil penelitian menunjukkan bahwa serovar Celledoni menginfeksi 25% anjing sehat dan 5% anjing sakit, serovar Javanica meninfeksi 19% anjing sehat, serovar Bataviae menginfeksi 15% anjing sakit, serovar Grippotyphosa menginfeksi 11% anjing sehat, serovar Tarrasovi menginfeksi 10% anjing sakit, serovar Cynopteri menginfeksi 5% anjing sehat dan 5% anjing sakit, serovar Pyrogenes menginfeksi 5% anjing sehat dan 5% anjing sakit, dan serovar Rachmati menginfeksi 5% anjing sakit. Tujuh ekor anjing sehat (19%) dan dua ekor anjing sakit (10%) terinfeksi lebih dari dua serovar leptospira. Dari hasil penelitian ini dapat disimpulkan bahwa infeksi Leptospira interrogans serovar Celledoni menyebabkan terjadinya leptospirosis subklinis, sedangkan infeksi serovar Bataviae menyebabkan leptospirosis klinis pada anjing-anjing di Yogyakarta.
