The incidence of Clostridium botulinum in fresh crabmeat of blue crab was six out of 986 samples; in pasteurized crabmeat one sample out of 1,000 contained the organism.

Sixty-two isolates of Clostridium sporogenes from canned foods were examined for cultural properties, heat resistance and DNA-DNA homology to Clostridium botulinum type A190. Sporulation was observed in most of 21 umbonate and rhizoidal colony-forming strains (colony-type I strains), but not in most of the 41 strains with convex and circular or crenate colonies with a mat to semi-glossy surface...

One strain of Clostridium botulinum belonging to type F has been isolated from a soil sample taken in Buenos Aires Province, Argentina. Comparative studies carried out with strain Langeland of C. botulinum type F have shown a few differences between the two strains.

Twelve strains of Clostridium botulinum type A and seven strains of Clostridium sporogenes were screened for plasmids by agarose gel electrophoresis of cleared lysates of cells from 5 ml of mid-log-phase culture. Nine type A strains had one or more plasmids of 4.3, 6.8, or 36 megadaltons (MDa); several strains showed a large plasmid of 61 MDa, but it was not consistently recovered. Four C. spor...

Soils from beaches in northwestern Alaska have been found to contain Clostridium botulinum type E, providing evidence of one environmental source of food contamination.

The first complete genome sequence of Clostridium sporogenes DSM 795(T), a nontoxigenic surrogate for Clostridium botulinum, was determined in a single contig using the PacBio single-molecule real-time technology. The genome (4,142,990 bp; G+C content, 27.98%) included 86 sets of >1,000-bp identical sequence pairs and 380 tandem repeats.

Food-borne diseases constitute a major public health problem. Due to increased morbidity and mortality leading to time loss in the work place and reduced productivity, food-borne diseases across the world cost billions of dollars annually1. The Clostridium group of bacteria is commonly found in soil everywhere in the world, and some of its species live harmlessly in our intestines. Clostridium ...

Here, we report the draft genome sequence of Clostridium botulinum B2 450, responsible for the first reported case of wound botulism in a drug user in Italy.

Botulism is one of the most important foodborne diseases and is caused by Clostridium botulinum toxin. The main manifestations are flaccid muscle paralysis and cranial nerve palsies. Botulism is an essential health problem because of its high mortality. The diagnosis of botulism, especially in sporadic cases, is a medical challenge and a high clinical suspicion is necessary for early recognitio...
