Abstract

This study examined 215 samples of soil from burrows of rats, other sites in bamboo plantations in different parts of India and Nepal by dilution plating and mouse passage technique for occurrence of Penicillium marneffei and other pathogenic fungi. None of the samples including 25 collected from the burrows of a bamboo rat (Cannomys badius) known to be a carrier of P. marneffei, was positive for the fungus. Among the pathogenic fungi recovered were four isolates of Pseudallescheria boydii (including one from Nepal), two of Trichosporon asteroides, one of Scytalidium hyalinum, 23 isolates of Trichophyton mentagrophytes var. mentagrophytes (including two from Nepal), and two of Microsporum gypseum. Fourteen of the 23 isolates of T. mentagrophytes var. mentagrophytes when tested with the mating types of Arthroderma vanbreuseghemii were found to be of the '+' mating type. The frequent recovery of this dermatophyte from soils of bamboo plantations in several parts of India is remarkable. The study also demonstrates for the first time the occurrence of P. boydii and T. mentagrophytes var. mentagrophytes in Nepalese soil. Among the other fungi recovered were several isolates of species of Aspergillus, Penicillium, Paecilomyces, Fusarium, Chrysosporium, Acremonium, Rhizopus, Mucor, Geotrichum, Trichosporon and Rhodotorula.
