Miscellaneous Human Pathogens

摘要: Besides three clinically important species in the genus Vibrio-V. cholerae, V. parahaemolyticus, and vulnificus-nine other Vibrio have been isolated from human infections. They include mimicus, Grimontia hollisae, fluvialis, furnissii, which are solely or principally gastroenteritis cases, alginolyticus Photobacterium damselae, chiefly associated with wound In addition, metschnikovii, cincinnatiensis, harveyi extraintestinal infections, but these isolations less frequent. The nine currently considered to be potential pathogens reportable public health surveys marine environment seafood. rare isolation of is partly due its unique growth biochemical characteristics. G. hollisae does not grow, grows very poorly, on selective media for enteric pathogens, including thiosulfate citrate bile salt sucrose (TCBS) agar MacConkey agar. Two factors that may play roles diarrhea studied. produces a hemolysin similar TDH (thermostable direct hemolysin) parahaemolyticus. Extracellular proteins (ECPs) cell-associated studied experimental models determine if furnissii possible diarrheagenic factor(s), results indicating culture filtrates some strains cause mortality suckling mice. virulence cultures depend production factors, nature differs strain strain.
