Streptococcus β-hemolisis merupakan bakteri yang dapat melisiskan darah dan biasanya bersifat patogen dapat menyebabkan penyakit strangles pada kuda. penelitian ini bertujuan untuk mengidentifikasi keberadaan bakteri streptococcus β-hemolisis pada luka kuda akibat penggunaan aksesoris di kabupaten aceh besar. penelitian dilaksanakan di laboratorium mikrobiologi fakultas kedokteran hewan universitas syiah kuala pada bulan desember 2024 – januari 2025. sampel yang digunakan berupa swab luka dari empat ekor kuda yang diambil dari tiga stable di kabupaten aceh besar. penelitian menggunakan metode cross sectional study. isolasi dan identifikasi bakteri dilakukan dengan metode carter (1987) yang dimodifikasi, menggunakan media nutrient broth (nb), dan blood agar plate (ba). identifikasi dilakukan melalui pewarnaan gram, uji katalase, dan uji hemolisa. hasil penelitian menunjukkan satu dari empat sampel positif terhadap streptococcus β-hemolisis. berdasarkan hasil penelitian dapat disimpulkan bahwa, streptococcus β-hemolisis dapat diisolasi dari 25% kuda yang terluka di kabupaten aceh besar.

Streptococcus β-hemolysis is a bacterium capable of lysing red blood cells and is generally pathogenic, known to cause strangles in horses. This study aimed to identify the presence of Streptococcus β-hemolysis in wounds on horses caused by the use of accessories in Aceh Besar District. The research was conducted at the Microbiology Laboratory of the Faculty of Veterinary Medicine, Syiah Kuala University, from December 2024 to January 2025. Samples were obtained by swabbing wounds from four horses collected from three stables in Aceh Besar District. This study employed a cross sectional study design. Bacterial isolation and identification were carried out using a modified version of the Carter (1987) method, utilizing Nutrient Broth (NB) and Blood Agar Plate (BA) media. Bacterial identification was performed through Gram staining, catalase test, and hemolysis test. The results showed that one out of four samples tested positive for Streptococcus β hemolysis. Based on these findings, it can be concluded that Streptococcus β-hemolysis can be isolated from 25% of horses with wounds in Aceh Besar District.
