Cezayir’de Sığırlarda Yanıkara Salgınında İzole Edilen Clostridium chauvoei Suşlarının Aşısal Özelliklerinin Araştırılması

Koyun ve Sığırlardan İzole Edilen Arcanobacterium pyogenes Suşlarının Moleküler Karakterizasyonu

The purpose of this study was to determine the presence of virulence genes, perform typing for the characterization of Arcanobacterium pyogenes field strains, and investigate the correlation between clonal types, virulence genes and occurence of disease. The isolates (n=51) used in this study were isolated from different sources (liver (n=4) of sheep; liver (n=25), lungs (n=5), broncho-alveolar...

Complexity of toxins from Clostridium septicum and Clostridium chauvoei.

Production of toxins by Clostridium septicum and Clostridium chauvoei has been the subject of many conflicting reports. Roux and Chamberland (1887) first noted that 3 to 4 day filtrates were antigenic; conferring on guinea pigs an immunity against infection with viable organisms. Production of a lethal toxin by C. septicum was however, demonstrated by Leclainche (1898) and Leclainche and Morel ...

Clostridium chauvoei, an Evolutionary Dead-End Pathogen

Full genome sequences of 20 strains of Clostridium chauvoei, the etiological agent of blackleg of cattle and sheep, isolated from four different continents over a period of 64 years (1951-2015) were determined and analyzed. The study reveals that the genome of the species C. chauvoei is highly homogeneous compared to the closely related species C. perfringens, a widespread pathogen that affects...

Immunizalion of Cattle with Clostridium chauvoei Vaccine

Sığırlardan ve Sektör Çalışanlarından İzole Edilen Metisilin Dirençli Stafilokokların Moleküler Tiplendirmesi

The aims of this study were to isolation and identification of methicillin resistant Staphylococcus aureus (MRSA) from mastitic cow milk and nasal swabs of cows and related workers, investigation presence of Panton-Valentine leucocidin (PVL) genes and molecular characteristics of these isolates. One hundred forty five mastitic milk samples were obtained from of 56 cows and nasal swabs were coll...
