microsporum canis ringworm epidemic in tehran

A zoonotic ringworm outbreak caused by a dysgonic strain of Microsporum canis from stray cats.

BACKGROUND Cats are frequent carriers of Microsporum canis and veterinary students are at high risk of exposure and acquisition of the organism a la infección. OBJECTIVES An outbreak of zoonotic ringworm carried by a litter of stray cats is described. Four veterinary students, four dogs, and six cats living in five separate locations were affected. All had direct or indirect contact with the ...

Dermatophytosis, Microsporum canis, Trichophyton mentagrophytes, Microsporum gypseum

Overview: The fungal skin disease dermatophytosis has come to be called ringworm because of the appearance of the skin lesion that characteristically occurs with this disorder: a circular area of hair loss with a red, raised outer rim. These lesions result from an inflammatory reaction to the fungus. Most often, dogs and cats are infected by the Microsporum canis fungus, but other types of fung...

Carbohydrate metabolism in Microsporum canis.

Enzyme systems concerned in the breakdown of carbohydrates by dennatophytes have been little studied, the principal contribution being a study of a number of enzymes of the glycolytic and hexosemonophosphate pathways and of the tricarboxylic acid cycle in cell-free extracts of Trichophyton mentagrophytes (Jensen, Altschuller & Bard, 1957). The effect of different substrates and pH values on the...

Studies of Ringworm. Part I. Microsporum Audouini Infection in India

RNA silencing in the dermatophyte Microsporum canis.

Dermatomycoses caused by Microsporum canis are frequent in domestic animals and easily transmissible to humans. Several proteases secreted by this fungus were identified as potential virulence factors, but the construction of deficient strains is required to investigate their role in the pathogenesis of the disease. Using target genes encoding two of these proteases, a first evaluation of the u...

The routine cultural identification of Microsporum ringworm of the scalp.

Tinea capitis in the United States is caused principally by Microsporum audouini and M. canis (lanosum). Identification of the responsible fungus is important in determining the prognosis. Identification of M. audouini by the usual method of planting infected hairs on agar media in a test tube requires 7 to 14 days. M. canis colonies are recognizable in 5 to 8 days. The method described below p...
