Toxinotype of Clostridium perfringens (CP) isolates collected from the Bernam River, Selangor River and Tengi Canal between April 2007 and January 2008 were determined by Polymerase Chain Reaction (PCR) using published primers. All the 147 isolates were toxinotype Type A, harbouring the alpha toxin gene. In addition, 5 of the isolates also had the enterotoxin (CPE) gene. Clostridium perfringens...

Alzheimer disease (AD) is the most frequent cause of dementia in Western countries. Putative genetic risk factors for AD are polymorphisms in the apolipoprotein E (APOE) gene and in the low-density lipoprotein receptor-related protein (LRP) gene. Our objective was to investigate the role of the APOE coding region polymorphisms epsilon 2, epsilon 3, and epsilon 4 and APOE promoter variants A/T a...

background: the mesobuthus eupeus scorpion venoms are known to contain α-toxin peptides, many of which interfere with k+ ion channel function. these toxin peptides have important value in  the pharmacology and physiology studies of specific k+ channel of cells. objectives: given the  lack of information of the molecular biology of peptides in the toxin of iranian scorpions, the aim of this stud...

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 mashhad city in northeastern of iran. after isolati...

We describe the genetic and kinetic defects for a low-affinity fast channel disease of the acetylcholine receptor (AChR) that causes a myasthenic syndrome. In two unrelated patients with very small miniature end plate (EP) potentials, but with normal EP AChR density and normal EP ultrastructure, patch-clamp studies demonstrated infrequent AChR channel events, diminished channel reopenings durin...

The objective of this study was isolating and characterising Clostridium perfringens from chickens in Vietnam identifying virulence factors involved with enteritis. Five hundred thirty-one faecal sixty-eight intestinal samples were collected healthy diseased for the C. isolation. presence determined by multiplex PCR. netB gene selected isolates sequenced checked its expression SDS-PAGE. Two sev...
