Query: NC_004344:257471 Wigglesworthia glossinidia endosymbiont of Glossina brevipalpis,
Lineage: Wigglesworthia glossinidia; Wigglesworthia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis. As Wigglesworthia brevipalpis resides intracellularly, the resulting co-evolution with its host over millions of years has led to a drastic reduction in the bacterium's genome size, resulting in this its inability to survive outside the host. Tsetse fly endosymbiont. This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis, Glossina tachinoides, Glossina palpalis palpalis, and Glossina austeni. The tsetse fly is a vector for African trypanosomes, and is the main transmitter of deadly diseases in animals and humans in Africa. The fly feeds on a restricted diet, exclusively consisting of vertebrate blood, and lacks certain metabolic compounds needed for survival and reproduction. To complement this lack in nutrients, the tsetse fly relies mainly on the intracellular bacterial symbiont, Wigglesworthia glossinidia for its viability and fecundity.
Subject: NC_005139:2731623 Vibrio vulnificus YJ016 chromosome I, complete sequence
Lineage: Vibrio vulnificus; Vibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: This is a Biotype 1 hospital isolate from Taiwan. It contains larger chromosomes and >1000 genes as compared to Vibrio cholerae and contains a conjugative plasmid, pYJ016. There are numerous virulence factors including a cytolysin, protease, capsular polysaccharide as well as iron-uptake systems encoded in the genome. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. Organisms of this species are opportunistic pathogens that can attack immunocompromised patients and causes gastroenteritis (inflammation of mucous membranes of stomach and intestine), wound infections, and primary septicemia (spread of the organism through the blood). This organism is the major cause of death from eating raw oysters, especially in people with liver damage. It only affects humans and other primates.
