Yersinia ruckeri was isolated from diseased unvaccinated rainbow trout obtained from a farm in which vaccination against enteric redmouth disease (ERM) has been systematically performed for more than 10 years. Affected fish presented typical signs of yersiniosis including exophthalmia and eye haemorrhages. Serological characterization of the isolate demonstrated that it belongs to the serotype ...

Rainbow trout infected with Yersinia ruckeri, the causative agent of enteric redmouth disease (ERM), produce a pro-inflammatory and acute-phase response attributed in part to the innate recognition of bacterial-produced flagellin. Recently, variants of Y. ruckeri have been identified that lack flagella and associated motility. These strains are classified as biotype 2 (BT2) Y. ruckeri and these...

Çalışmada gökkuşağı alabalıklarından izole edilen 20 adet Yersinia ruckeri izolatının biyofilm oluşturma yeteneği ve bazı virülens faktörleri fenotipik olarak incelendi. İzolatların yeteneklerinin belirlenmesinde Kongo Red Agar (CRA), Modifiye Tüp Aderans (Christensen) Mikroplak yöntemleri kullanıldı. hareket özelliği, hemolitik aktivitesi, lipaz aktivitesi proteaz metotlar ile ortaya konuldu. ...
