Query: NC_012563:4101000 Clostridium botulinum A2 str. Kyoto, complete genome

Lineage: Clostridium botulinum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria

General Information: This strain was isolated from a case of infant botulism in Kyoto, Japan in 1978. This organism produces one of the most potent and deadly neurotoxins known, a botulinum toxin that prevents the release of acetylcholine at the neuromuscular junction, thereby inhibiting muscle contraction and causing paralysis. In most cases the diseased person dies of asphyxiation as a result of paralysis of chest muscles involved in breathing. The spores are heat-resistant and can survive in inadequately heated, prepared, or processed foods. Spores germinate under favorable conditions (anaerobiosis and substrate-rich environment) and bacteria start propagating very rapidly, producing the toxin.Botulinum toxin, and C. botulinum cells, has been found in a wide variety of foods, including canned ones. Almost any food that has a high pH (above 4.6) can support growth of the bacterium. Honey is the most common vehicle for infection in infants. Food poisoning through C. botulinum is the most frequent type of infection caused by this bacterium. The wound botulism that occurs when C. botulinum infects an individual via an open wound is much rarer and is very similar to tetanus disease. There are several types of botulinum toxin known (type A through type F), all of them being neurotoxic polypeptides. The most common and widely distributed are strains and serovars of C. botulinum that produce type A toxin.

Subject: NC_009901:2915939 Shewanella pealeana ATCC 700345, complete genome

Lineage: Shewanella pealeana; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria

General Information: This species was isolated from a microbial community colonizing the accessory nidamental gland of the squid Loligo peali (Atlantic squid) for their capacity to respire on sulfur. It was placed in the Shewanella genus based on physiological and biochemical characteristics and 16S rRNA sequence analysis. Shewanella are ubiquitous in marine environment and play very important role in global carbon and nitrogen cycle. The present strain is moderately halophilic, requiring sodium ions for growth. Shewanella are facultatively anaerobic, Gram-negative bacteria, motile by polar flagella, rod-like, and generally associated with aquatic or marine environments.
