Clostridium strains from six phylogenetic groups, C. botulinum groups I to IV, C. baratii, and C. butyricum, display the capacity to produce botulinum neurotoxin. Here, we present the genome sequence of a C. butyricum isolate, the neurotoxigenic strain 5521, which encodes the type E botulinum neurotoxin.

Background Clostridium difficile is currently the most frequent cause of nosocomial diarrhea but also cause of disease in the community, antibiotic therapy and hospitalizations related; advanced age (over 60 years), malignancies, chronic kidney disease are also risk factors for infection with Clostridium difficile. The incidence of Clostridium difficile increases all over the world. The complic...

introduction: clostridium difficile is the etiologic agent of several infections such as pseudomembranous colitis in human. these diseases are frequently associated with antibiotic useage but many infections with this organisms are seen without antibiotic administration. in addition it is believed that clostridium difficile is one of the most important bacteria involved in acquired hospital inf...

clostridial myositis, considered to be rare in pet animals, is an acutely fatal toxaemic condition. some species of clostridia are responsible for necrotic myositis. a 2-year-old male german shepherd dog was admitted with non-weight bearing lameness and massive swelling of the left hind limb. clostridium perfringens type a with alpha toxin was diagnosed as a pathogenic agent. based on the histo...

introduction botulism is an acute form of poisoning resulted from ingestion of clostridium botulinum toxin. case presentation here we present five cases of food-borne botulism poisoning from home produced cheese. five patients from one family referred to our emergency unit with complaints of weakness and two had severe symptoms. in spite of the laboratory negative results antitoxin was administ...

background: reduced susceptibility of clostridium difficile to antibiotics is problematic in clinical settings. there is new evidence indicating the cotransfer of toxin-encoding genes and conjugative transposons encoding resistance to antibiotics among different c. difficile strains. to analyze this association, in the current study, we evaluated the frequency of toxigenic c. difficile among th...

objective botulism is the acute, descending, flaccid paralysis that results when the neurotoxin of clostridium botulinum blocks neuromuscular transmission. c botulinum toxin is the most poisonous substance that blocks neuromuscular transmission and causes death through airway and respiratory muscle paralysis; all forms of botulism manifest neurologically as asymmetric, descending, flaccid paral...

aim : in this study, the prevalence of c. difficile , from patients with gastrointestinal complaints and its association with other enteropathogen microbes were investigated. background : clostridium difficile is an important pathogen associated with outbreaks of pseudomembranous colitis and other intestinal disorders, such as diarrhea. patients and methods : enterotoxin and cytotoxin (toxin a ...

Context. Clostridium perfringens septicemia is often associated with translocation from the gastrointestinal or gastrourinary tract and occurs in patients who have malignancy or are immunocompromised. Clostridium perfringens septicemia is usually fatal without early identification, source control, and antibiotics. Case. We present a case of a 65-year-old female with Clostridium perfringens sept...

clostridium perfringens is an important pathogen that provokes numerous different diseases. this bacterium is classified into five various types, each of which capable of causing a distinct disease. there are various methods for the bacterial identification, many are labor-intensive, time-consuming, expensive and also show low sensitivity and specificity. the aim of this research was to identif...
