Query: NC_009443:277246 Streptococcus suis 98HAH33, complete genome

Lineage: Streptococcus suis; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: Isolated from a human in Haian County, Jiangsu Province, China, 1998. Causative agent of meningitis, endocarditis, septicemia and arthritis in swine. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Streptococcus suis is a pathogen of pigs and is responsible for a variety of diseases including meningitis, arthritis and pneumonia. Occasionally this organism can infect humans causing septicemia, meningitis and endocarditis.

Subject: NC_012225:236490 Brachyspira hyodysenteriae WA1, complete genome

Lineage: Brachyspira hyodysenteriae; Brachyspira; Brachyspiraceae; Spirochaetales; Spirochaetes; Bacteria

General Information: Brachyspira hyodysenteriae is the causative agent of swine dysentery, which is a severe mucohemorrhagic diarrheal disease of pigs that has economic significance for pork-producing countries. The bacterium can survive for several weeks in cold moist conditions but not under warm dry conditions. It spreads slowly, building up in numbers as the dose rate of the causal agent builds up in the environment. Pigs that recover develop a low immunity and rarely suffer from the disease again. It can be spread by other organisms (flies, mice, birds and dogs) or external mechanical factors; its main habitat is the porcine cecum and colon. It is chemotactically attracted to mucin which it penetrates with a corkscrew-like motility.
