Cytological observations on the sporulation process of Clostridium perfringens.

Some Observations on Clostridium perfringens Strains Isolated in IRAN

Identification and characterization of sporulation-dependent promoters upstream of the enterotoxin gene (cpe) of Clostridium perfringens.

Three promoter sites (P1, P2, and P3) responsible for the sporulation-associated synthesis of Clostridium perfringens enterotoxin, a common cause of food poisoning in humans and animals, were identified. Nested and internal deletions of the cpe promoter region were made to narrow down the location of promoter elements. To measure the effects of the deletions on the expression of cpe, translatio...

Genome-Wide Transcriptional Profiling of Clostridium perfringens SM101 during Sporulation Extends the Core of Putative Sporulation Genes and Genes Determining Spore Properties and Germination Characteristics

The formation of bacterial spores is a highly regulated process and the ultimate properties of the spores are determined during sporulation and subsequent maturation. A wide variety of genes that are expressed during sporulation determine spore properties such as resistance to heat and other adverse environmental conditions, dormancy and germination responses. In this study we characterized the...

Sporulation of Clostridium botulinum types A, B, and E, Clostridium perfringens, and putrefactive anaerobe 3679 in dialysis sacs.

Schneider, Morris D. (Quartermaster Food and Container Institute for the Armed Forces, U.S. Army, Chicago, Ill.), Nicholas Grecz, and Abe Anellis. Sporulation of Clostridium botulinum types A, B, and E, Clostridium perfringens, and Putrefactive Anaerobe 3679 in dialysis sacs. J. Bacteriol. 85:126-133. 1963.-Concentrated cultures of spores of Clostridium botulinum type A (33A, 37A), B (41B, 51B)...

The Agr-like quorum-sensing system regulates sporulation and production of enterotoxin and beta2 toxin by Clostridium perfringens type A non-food-borne human gastrointestinal disease strain F5603.

Clostridium perfringens type A strains producing enterotoxin (CPE) cause one of the most common bacterial food-borne illnesses, as well as many cases of non-food-borne human gastrointestinal disease. Recent studies have shown that an Agr-like quorum-sensing system controls production of chromosomally encoded alpha-toxin and perfringolysin O by C. perfringens, as well as sporulation by Clostridi...
