canimorsus was previously known as CDC group DF-2 (dysgonic
fermenter type 2) and was first isolated from a man who had experienced multiple dog bites and developed septicemia and meningitis.
A zoonotic ringworm oubreak caused by a dysgonic
strain of Microsporum canis from stray cats.
A zoonotic ringworm outbreak caused by a dysgonic
starin of Microsporum canis from stray cats.
The bacterium can be identified now by the characteristic disease it produces in guinea pigs, the characteristic death pattern in eggs, the at best dysgonic
growth on the bacterial media tried, and by the fluorescent antibody staining results.
bovis shows a dysgonic
colony shape on Lowenstein-Jensen medium, is negative for niacin accumulation and nitrate reduction, is susceptible to thiophene-2-carboxylic acid hydrazide (TCH), and shows microaerophilic growth on Lebek medium (1-3).
canirnorsus, previously classified as CDC Group Dysgonic Fermenter-2 (DF-2), is a slow-growing, gram-negative bacterium that requires carbon dioxide for growth (2).
Dysgonic fermenter-2: a clinico-epidemiologic review.
bovis shows dysgonic
growth on Lowenstein-Jensen (LJ) medium and has been described as negative for nitrate reduction and niacin accumulation (2).
Subcultures remained negative on L6wenstein-Jensen slants but after approximately 4 weeks became positive on mycobactin-supplemented Middlebrook slants with colorless dysgonic
