Questions and Answers List

level questions: Gram negative facultative anaerobes

QuestionAnswer
Citrobacter- gram negative facultative anaerobes - rods, usually motile - mesophilic - found in the intestinal tract of humans, animals, and birds; in the environment - coliform; indicator organism
Escherichia- gram negative facultative anaerobes - motile or nonmotile rods - mesophilic - found in intestinal tract of humans, warm blooded animals, birds; environment - many strains non-pathogenic - some pathogenic to people and animals - coliform; indicator organism
Enterobacter- gram negative facultative anaerobes - motile rods - mesophile - in the intestinal tract of humans, animals, and birds - coliform; indicator organsim
Klebsiella- gram negative facultative anaerobes - motile, capsulated rods - mesophile - found in intestinal tract of humans, animals, and birds; soil water, and grains - coliform; indicator organsim
Hafnia- gram negative facultative anaerobes - motile rods - mesophilic - found in intestinal tract of humans, animals, birds; in the environment - cause spoilage of refrigerated meats and vegetable products
Salmonella- gram negative facultative anaerobes - typ. motile rods, - mesophilic - > 2000 serovars - human pathogens - in intestinal tract of humans, animals, birds, insects - major cause of foodborne disease
Shigella- gram negative facultative anaerobes - nonmotile rods - mesophilic - in intestinal tract of humans and primates - human pathogen - associated with foodborne disease
Proteus- gram negative facultative anaerobes - motile rods - swarming on agar media - peritrichous flagella - mesophilic, some are psychrotrophic - found in intestinal tract of humans and animals, and in the environment - many involved in food spoilage
Yersinia- gram negative facultative anaerobes - motile and non motile rods - psychrotrophic (can grow at 1 C) - found in the intestinal tract of animals - associated with foodborne disease
Serratia- gram negative facultative anaerobes - motile pink rods - form pink or red colonies on agar media - occur in the environment - some can grow at refrigerator temperatures - food spoilage organism
Vibrio- gram negative facultative anaerobes - motile curved rods - mesophilic - found in fresh water and marine environments - some species req. NaCl for growth - some species are human pathogens - some cause food spoilage (Vibrio alginolyticus)
Vibrio examples- human pathogens: Vibrio cholerae, V. parahemolyticus, V. vulnificusd - food spoilage: V. alginolyticus
Aeromonas- gram negative facultative anaerobes - motile rods - psychrotrophic - large amount of gas produced from sugars - found in intestinal tract of fish - some are fish pathogens
Aeromonas examples- Aeromonas hydrophiliaI: foodborne pathogen
Plesiomonas- gram negative facultative anaerobes - motile rods - pathogen - mesophilic - found in surface water, soil, fresh water fish, aquatic animals - more prevalent during warmer seasons
Plesiomonas example- foodborne pathogen: Plesiomonas shigelloides
