Titration of kappa toxin of Clostridium perfringens and kappa antitoxin by a modified azocoll method.

Double Sandwich ELISA Modified Method for the Detection of Clostridium Botulinum Type E

Background & Objective: A very small amount of botulinum toxin can cause death and on the other hand, there is no cure for its poison other than antitoxin. Therefore, a diagnostic method that can detect very small amounts of botulinum toxin in a short time is very important. In this study, rapid and accurate detection of botulinum toxin type E has been performed with the double sandwich ELISA m...

Cloning of Clostridium perfringens iota toxin gene in Escherichia coli

Iota toxin is produced by Clostridium perfringens type E. This toxin causes antibiotic-associated enterotoxemia in lambs and calves. Iota toxin is a binary toxin that has two components including Ia (the enzyme component) and Ib (the binding component). Ib binds to the surface receptor of target cells and translocate Ia into the cytosol of cells. The aim of this study was to clone toxigenic epi...

Preparation of Standard Clostridium perfringens Antitoxin in the Sheep

Genotyping of Clostridium perfringens isolated from broiler meat in northeastern of Iran

Clostridium perfringens is an important cause of bacterial food poisoning worldwide. The disease is caused by C. perfringens enterotoxin (CPE) encoded by cpe gene. The aim of this research was to identify the different types of C. perfringens and the presence of cpe gene in isolated bacteria from broilers’ meat marketed in retail meat shops of Mashha...

Occurrence of Beta2 toxigenic Clostridium perfringens isolates with different toxin types in Iran

Clostridium perfringens is an important cause of enteric diseases in both human and animals. The bacteria produce several toxins which play key roles in the pathogenesis of diseases and are classified into five toxin types, on the basis of the differential production of Alpha, Beta, Epsilon and Iota toxins. In this study a single PCR assay was developed and used for detection of cpb2 gene to id...
