Abstract
Bursa ili İznik ilçesinde 120 adet koyun ve keçinin birarada yetiştirildiği bir işletmede akut eksudatif dermatitis olgusu gözlendi. Sürüdeki 50 adet keçinin yaklaşık %70’i, 70 adet koyunun ise %25’inde semptomlar gözlendi. Lezyonların genellikle baş bölgesinde olduğu saptandı. Deri lezyonlarından alınan kabuk örnekleri bakteriyolojik ve mikolojik yönden incelendi. Bakteriyoskopide; örneklere Giemsa boyama uygulandı ve ardışık dizili koklar düzensiz, uzun ve büyük filamentler halinde gözlendi. Kabuklarda %10 KOH ile yapılan incelemede, mikolojik bulguya rastlanmadı. Bakteriyolojik tanı amacıyla %5 koyun kanlı agara yapılan ekimler 37°C’de, %5-10 CO2 ‘li ortamda 24-48 saat inkübe edildi. İnkübasyon süresi sonunda; ilk 24 saatte çapı 1 mm’nin altında olan ince koloniler, 48 saat sonunda ise yaklaşık 1 mm çapında β-hemolizli, kuru, agara gömülü koloniler gözlendi. Gram boyama sonucunda koloniler Gram pozitif kokoid formda görüldü. Bakteriyoskopi ve kültür incelemeleri sonucunda yapılan değerlendirmede etken Dermatophilus congolensis olarak
A case of acute exudative dermatitis was observed in a herd breeding of totally 120 goats and sheeps in Bursa İznik district. The symptoms were observed approximately 70 % of 50 goats and 25 % of 70 sheeps. The lesions generally were located around head parts of animals. Scabs that collected from skin lesions were investigated bacteriologically and mycologically. Giemsa stain was applied and the bacteria was seen as branching filaments containing multiple rows of cocci. No mycologic findings were determined in scabs that applied 10% KOH. The samples were inoculated 5% sheep blood agar and incubated at 37 0 C in 5-10% CO2 atmosphere at 24-48 hours for bacteriological examination. While the colonies were formed under of 1 mm diameter after 24 hours, colonies were observed β-hemolytic, hard, adherent to agar surface and about 1 mm diameter after 48 hours. Gram-positive coccoid forms were seen in Gram stain. Dermatophilus congolensis was identified after bacterioscopy and culture.
