Nonspore Forming - GPR

Corynebacterium sp. "diptheroids": [blank_start]Small[blank_end], pleomorphic, beaded, palisading "Chinese Letters" -> [blank_start]Dry[blank_end], [blank_start]white[blank_end] colonies -> Catalase [blank_start]positive[blank_end]

Listeria monocytogenes: [blank_start]small[blank_end] coccobacillary -> [blank_start]narrow[blank_end]-zone, [blank_start]beta[blank_end] hemolytic colonies -> catalase [blank_start]positive[blank_end] -> umbrella & tumbling, Motility at 25C, Litmus milk-chalky, white, indicator [blank_start]red[blank_end]. Salicin +, Dextrose +, Trehalose +, Bile esculin +

Erysipelothrix: thin, [blank_start]small[blank_end], pointed rod -> small, [blank_start]alpha[blank_end] hemolytic -> catalase [blank_start]negative[blank_end] -> TSI=H25

Lactobacillus sp: [blank_start]long[blank_end], thin GPR in chains -> small, [blank_start]alpha[blank_end] hemolytic -> catalase [blank_start]negative[blank_end]

Listeria's main source is dairy products such as milk, cheese and icecream

Listeria is manifested primarily as [blank_start]septicemia[blank_end] and [blank_start]meningitis[blank_end] in neonates and immuno-compromised patients

For what microorganism do you use the rabbit monocyte test?

Normal habitat: sewage, silage, soil, fertilizers, decaying vegetation Normal flora of GI tract of many animals-often found in milk (cows, goats) 1-5% of humans are asymptomatic intestinal carriers

Normal habitat: animals such as fish, shellfish, birds (poultry), swine (major reservoir), rodents, cattle, horses, dogs soil, food, water organism is able to survive for long periods outside of the body and survives pickling, salting, or smoking processes used in preservation of meats

Normal Habitat: Female genital tract, GI tract, skin, found in dairy products

Normal habitat: upper respiratory tract, many individuals carry nontoxigenic strains as a part of NF
