Yenidoğan Bir Buzağıda Zoonotik Campylobacter jejuni'nin İzolasyonu ve İdentifikasyonu

Campylobacteriozis tüm dünyada yaygın görülen zoonoz bir enfeksiyondur. Bu olguda; iştahsızlık ve ishal gözlenen, antibiyotik ve vitamin preperatları ile yapılan semptomatik tedaviye de cevap vermeyerek ölen yeni doğan (yedi günlük) buzağıda Campylobacter jejuni tanımlanmıştır. Otopsisinde akciğerlerde hiperemi, karaciğerde dejenerasyonlar, dalakta nekrotik odaklar, barsaklarda kataral ve hemorajik değişiklikler görülen buzağının dokularının histopatolojik incelemesinde, barsak epitellerinde yer yer dökülmeler görüldü .Akciğerlerinde bağdoku artışı, alveollerde dejenerasyon ve çevrelerinde lenfosit infiltrasyonu, bronşlarda yoğun bakteri kümeleri, damar endotellerinde dökülmeler görüldü. Karaciğerde portal boşluklarda lenfosit infiltrasyonu, damarlarda trombozlar ve çeperlerinde kalınlaşmalar, hepatositlerde erime nekrozu ve dejenerasyon, dalakta kas trabeküllerinde kalınlaşmalar, kalp kasında ödem gözlendi. Bakteriyolojik incelemelerde Campylobacter jejuni izole ve identifiye edildi.

The Isolation and Identification of Zoonotic Campylobacter jejuni from a Newborn Calf

Campylobacteriosis is a worldwide zoonotic infection. In this case report, Campylobacter jejuni was described in a newborn calf (seven days old) that had been suffered from diarrhea and loss of appetite and not responded to symptomatic antibiotic and vitamin treatments. In the necropsy, pulmonary hyperemia in the lungs, degenerations in the liver, focal necrosis in the spleen, cataral and necrotic alterations in the intestines were seen. In the histopathological examinations, desquamation in some areas of the intestinal epithelium of increases in the connective tissues of the lungs, degenerations in alveolus and lymphocyte infiltration around them, bacterial clumpsin bronches, disintegrations of endothelium of blood vessels were seen. Lymphocyte infiltrations in liver portal space, thrombosis in blood vessels and thickness in the blood vessel walls, degeneration in hepatocytes were seen. Thickness of spleen and muscle trabeculas, oedema in heart muscle were observed. In the bacteriological examinations, Campylobacter jejuni was isolated and identified.
