in this research a molecular method based on polymerase chain reaction for typing of clostridium perfringens was developed and toxin genotypes of 64 isolates from sheep and goats in iran were determined. the pcr assays were developed for detection of alpha (cpa), beta (cpb) and epsilon (etx) toxin genes, allowing classification of the isolates into genotypes a b, c and d. the field isolates ...
conclusions periodic evaluation of antimicrobial susceptibility for c. perfringens should be performed. harboring of enterotoxigenic c. perfringens in individuals not necessarily results in diarrhea. results of 136 stool samples including diarrhea [48] and non-diarrhea [88] ones, 83 (61.02%) c. perfringens were cultured. of these 83, 79 c. perfringens isolates showed the alpha-toxin (phospholip...
Tetanus is a life-threatening neurologic disease caused by an infectious agent, Clostridium Tetani, and is one of the infectious diseases that is preventable by vaccination. Tetanus is characterized by painful muscle spasm and increased muscle tone, that is caused by tetanospasmin, a powerful toxin elaborated by Clostridium tetani. Due to worldwide regular vaccination, this disease rarely see...
It is known that the major etiologic agent of pseudomembranous colitis in man is Clostridium difficile. With respect to traditional use of almond paste in the treatment of infantile diarrhea, we studied the effects of the aqueous extract of Amygdalus communis (AEAC) on the growth and toxin production of Clostridium difficile in culture medium and the rabbit ligated ileal loop. Three groups...
Background and purpose: Clostridium difficile is an obligate anaerobic, gram positive bacillus. The purpose of this study was to develop and optimize Loop-mediated Isothermal Amplification (LAMP) technique for assessing the prevalence of Clostridium difficile infection in the samples of watery diarrhea. Material and methods: This cross-sectional qualitative study was performed in 48 samples of...
Abstract Background: Clostridium difficile infection (CDI) has been a major growing problem in hospitals in recent years. Detection of the source of Clostridium difficile strains is of importance for the control of the nosocomial spread of this microorganism. This study was done to identify C.difficile isolates by polymerase chain reaction, (PCR), ribotyping. Materials and methods: The descript...
A Longitudinal epidemiologic study was developed for the isolation, biochemical characterization and molecular typing the bacterial pathogen Clostridium spp found in soil from areas affected by bovine sudden mortality. Weincluded 10 herds, located in three localities. The genetic variability of Clostridium genus was analyzed by DNA sequence of a 1500 bp fragment from the 16S rRNA gene. Twenty f...
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...
conclusions metronidazole and vancomycin still seem to be most effective drugs for treatment cdi. objectives the aim of this study was to investigate the antimicrobial susceptibility patterns of c. difficile clinical isolates against antibiotics commonly used for treatment cdi in hospitalized patients. material and methods during a 12 month study, 75 c. difficile isolates were collected from 39...
