Dermatophyties, dépilations pseudo-dermatophytiques et portage sain cutané observés sur des Primates Platyrhiniens et Cynomorphes

Abstract

Résumé.Les teignes le plus fréquemment rencontrées chez les singes Platyrhiniens et Cynomorphes sont des microspories à Microsporum canis ou des trichophyties à Trichophyton mentagro phytes ou T. simii. Espèce anthropo-zoophile, le T. mentagrophytes doit être distingué plus spécialement de T. rubum et T. interdigitale, dermatophytes de l'homme ; en cas d'isolements atypiques, différents tests sont utilisés pour la diagnose.Sur les 226 sujets examinés, il a été enregistré : 2 trichophyties à T. mentagrophytes (un onyxis chez un Sajou capucin et une implantation dorsale chez une Mone de Campbell) et 13 cas de lésions pseudo-dermatophytiques, sans isolement de dermatophyte. Parmi 40 des 211 singes sans lésions de la peau et des phanères, il a été décelé 14 porteurs de champi gnons kératinophiles (2 T. terrestre, 1 Keratinomyces ajelloi, 5 Chrysosporium keratinophilum et 7 Chrysosporium sp.). La question des dépilations des primates d'origine non dermatophytique a été discutée. Summary.Dermatophytosis, pseudo-dermatophytosis and healthy cutaneous portage observed in Platyrhini and Cynomorpha monkeys.

Skin mycoflora of Cebus primates kept in captivity and semicaptivity

“…The lack of dermatophyte fungi isolated from the skin of the 134 primates of the genus Cebus used in this study corroborates the findings of other authors . However, in a study conducted with 226 animals of 27 primate species, there were two isolations of Trichophyton mentagrophytes : a capuchin monkey ( Cebus capucinus ) with a nail lesion and a mona monkey with a dermatophytic lesion on its thoracic dorsal region ( Cercopitecus mona ) .…”

“…Due to the lack of similar studies performed in primates of the genus Cebus, the results can only be partially compared. Thus, it was only possible to compare the [31,32] and Japan [15]. The lack of dermatophyte fungi isolated from the skin of the 134 primates of the genus Cebus used in this study corroborates the findings of other authors [2, 15,31].…”

“…Due to the lack of similar studies performed in primates of the genus Cebus , the results can only be partially compared. Thus, it was only possible to compare the data obtained here with those of surveys carried out on other species of primates that were performed in the USA , France and Japan .…”

“…This hypothesis differs from results of others who stated that the variation found in the skin of primates was due to the environmental conditions of animal care . Another publication asserted that the skin microbiota of the monkeys reflected that of the soil where the animals were kept in the study , and another one, in turn, considered that keratinophilic fungi found in healthy primates were transferred from the dirt floor of the enclosure to the animals . Finally, another study concluded that the isolated fungi from cynomolgus monkeys came from the air, the natural habitat or contamination, and the author did not observe a clear correlation between the genera of fungi and the anatomical region from which they were isolated .…”

Use of a Sustained Release Preparation of Clotrimazole to Treat Dermatophytosis in a Siamang (Hylobates syndactylus)

“…In captive primates, there was one survey of 226 captive New World primates that documented two clinical cases and 40 positive cultures from nonsymptomatic animals. 10 Dermatophytosis in a rhesus monkey (Macaca mulatta) due to M. canis was reported in a biomedical research colony. Clinical signs were generalized alopecia and numerous circumscribed raised plaques.…”
