| an atypical microsporum canis isolate. | an atypical strain of microsporum canis isolated from a two-year-old boy with tinea corporis is described. when cultured on lactritmel agar the strain presented the typical pigment of m. canis without developing characteristic macroconidia. after 6 weeks, scarce, rudimentary, fusiform macroconidia 120-150 microns long developed on lactritmel and sablac microcultures. in vitro, the strain developed hair perforating organs. experimental inoculation of a healthy volunteer produced a tinea with typi ... | 1991 | 1824421 |
| microsporum canis with polymorphous macroconidia. | an atypical strain of microsporum canis was isolated in our laboratory, which was characterized by a variety of polymorphous macroconidia. these are demonstrated by illustrations. based on our observation and literature, the relationship between microsporum canis and microsporum distortum is discussed. epidemiologic aspects are mentioned. | 1989 | 2747740 |
| the changing clinical picture of microsporum canis infections in sweden. | all 22 cases of infections with microsporum canis verified by culture during a five-year period were surveyed. only tinea corporis was found. the clinical picture was varied and in more than half of the cases the preliminary diagnosis was other than tinea. the classical tinea capitis was not found in any case. direct koh-mounts showed poor correlation to the cultural findings (positive in 33%). it is concluded that mycological screening of certain dermatological disorders should be performed by ... | 1982 | 6187167 |

| an outbreak of dermatophytosis in pigs caused by microsporum canis. | an outbreak of dermatophytosis caused by microsporum canis in a porcine farm is described. the morbidity was 100% among sows, 95% among new-borns and 75% among feedlot animals. microsporum canis was also isolated from walls and environmental air. | 1995 | 7544873 |
| experimental immunity to microsporum canis and cross reactions with other dermatophytes of veterinary importance. | an inactivated, broad-spectrum dermatophyte vaccine was used to produce an active immunity in guinea-pigs against microsporum canis. none of the vaccinates developed infection from a contact exposure challenge that produced clinical infections in 70% of the unvaccinated controls. infection with m. canis induced antibody titres (elisa) and delayed cutaneous hypersensitivity (dch) reactions to itself as well as cross-reacting titres to trichophyton equinum and t. mentagrophytes and dch reactions t ... | 1995 | 7658308 |
| [spread of a microsporum canis infection in an agricultural facility (case description)]. | in a combined pig production and fattening unit the weaned piglets on the flatdecks and some young fattening pigs were suffering from a microsporum canis-infection. besides the pigs the children of the farmer showed skin alterations. the infection was spread probably by the cats, which had access to the houses for sows and for sows with piglets. in cases of uncertain skin alterations, a mycologic etiology should be considered. | 1994 | 7717960 |
| immunogenicity in guinea-pigs of a crude ribosomal fraction from microsporum canis. | the immunogenicity of a crude ribosomal fraction (crf) extracted from microsporum canis was tested by assessing protection of vaccinated guinea-pigs (gp) against a challenge with the dermatophyte. stimulation of the humoral as well as the cellular immune systems of these animals was evaluated by elisa and the lymphocyte stimulation tests, respectively. in addition, the immune response elicited by the m. canis crf was examined for cross-reactivity towards trichophyton verrucosum antigen. the dura ... | 1994 | 8147094 |
| [microsporum canis as the origin of an enzootic outbreak in swine. a case report]. | we report on the outbreak of dermatomycosis caused by microsporum canis at a bavarian pig breeding and fattening farm. clinical signs were shown mainly by younger pigs. microsporum canis could be identified in skin scrapings of pigs, cats, and the farmer's daughter by culture and fluorescence microscopy. questions of epizootiology, diagnostics and therapy are discussed. | 1995 | 8585059 |
| dermatophytes isolated from domestic animals in barcelona, spain. | this retrospective study deals with the main samples studied at the mycology diagnostic service of the faculty of veterinary science of barcelona: animals with suspected dermatophytosis. over a ten-year period from 1986 to 1995, 136 dermatophytes were identified from dog and cat cultures submitted for identification and from specimens submitted for mycological examination from a variety of other domestic animals. the most frequent dermatophytes isolated were microsporum canis (55.9%), trichophyt ... | 1997 | 9335154 |
| butenafine. | butenafine is a new antifungal agent with primary fungicidal activity against dermatophytes such as trichophyton mentagrophytes, microsporum canis and trichophyton rubrum which cause tinea infections. 14c-labelled butenafine (approximately 30 micrograms/g tissue) was found within guinea-pig dorsal skin 24 hours after topical application. most of the drug was distributed into the epidermis including the horny layer. small amounts were found in the dermis, probably transported via sebaceous glands ... | 1998 | 9530545 |
| ultraviolet c inactivation of dermatophytes: implications for treatment of onychomycosis. | onychomycosis responds to systemic antifungals and sometimes to topical lacquers, but alternative treatments are desirable. topical application of germicidal ultraviolet (uv) c radiation may be an acceptable and effective therapy for infected nails. | 2008 | 18410410 |
| dermatophytoses in animals. | dermatophytoses are one of the most frequent skin diseases of pets and livestock. contagiousness among animal communities, high cost of treatment, difficulty of control measures, and the public health consequences of animal ringworm explain their great importance. a wide variety of dermatophytes have been isolated from animals, but a few zoophilic species are responsible for the majority of the cases, viz. microsporum canis, trichophyton mentagrophytes, trichophyton equinum and trichophyton verr ... | 2008 | 18478363 |
| secreted dipeptidyl peptidases as potential virulence factors for microsporum canis. | dermatophytoses caused by microsporum canis are frequently encountered in cats and dogs; they are highly contagious and readily transmissible to humans. in this study, two single genes, respectively coding for dipeptidyl peptidases iv and v (dppiv and dppv), were isolated and characterized. both proteins share homology with serine proteases of the s9 family, some of which display properties compatible with implication in pathogenic processes. both genes are expressed in vivo in experimentally in ... | 2008 | 19049642 |
| secreted subtilisin sub3 from microsporum canis is required for adherence to but not for invasion of the epidermis. | microsporum canis is a pathogenic dermatophyte that causes a superficial cutaneous mycosis, mainly in cats and humans. proteolytic enzymes, including subtilisins, have been postulated to be key factors involved in adherence and invasion of the stratum corneum and keratinized epidermal structures. | 2010 | 19995373 |
