Microscopic observation of human hairs infected with Microsporum ferrugineum.

Human hairs infected with Microsporum ferrugineum were examined by light and scanning electron microscopy to obtain information on the parasitic form. The fungus invaded the hair filaments and developed hyphae between the hair cuticles and cortex. Spheroids of arthroconidia were frequently observed to invade the hair follicle. A mosaic sheath of massive spheroids was observed around the hair filaments. The smooth-walled arthroconidia with chitinous surfaces were single, spherical or subspherical particles of 2.0-2.5 X 2.5-3.5 microns, and 2-celled, gourd-shaped (constricted at the septum) particles of 2.5-3.0 X 5.0-7.0 microns.

Fungal flora of the conjunctival sac.

We studied the fungal flora of the conjunctival sac in 919 eyes and air-borne fungi between November 1979 and February 1980. Fungi were cultured from 39 of 587 swabs (6.6%) from healthy conjunctivas. This incidence fluctuated with the number of air-borne fungi. The incidence of positive cultures was significantly higher in diseased eyes (32 of 184 eyes; P less than .005). Under ordinary conditions, it may be difficult for a fungus to remain or proliferate in the conjunctival sac. Most (97 of 103) positive cultures yielded only one colony and the same fungus was seldom cultured more than once from the same eye. We found 49 strains of yeast among the 107 isolated conjunctival fungi, including 15 Mycelia sterilia, 12 Cladosporium, and several Aspergillus, Fusarium, and Rhizoctonia species. THe air-borne fungi were mainly the filamentous types, especially Cladosporium and Alternaria.

Dermatophytosis of tiger caused by Microsporum canis.

Microsporum canis was isolated from the inflammatory skin lesions of a Bengal tiger in April, 1979. In clinical findings rounded area of alopecia, 3 to 8 cm in size was observed on the right haunch and the tail. The skin lesions were covered with thin scales, but the inflammatory changes were not severe. Findings, on physical examination, were unremarkable and the animal appeared healthy except for the skin lesions. The infected hairs were invaded by the fungal elements and arthroconidia were around the hair shaft. Cuticles and cortex of the infected hairs were brittle. They were evidently digested and were easily pulled out from the hair follicles. In mycological findings numerous and typical macroconidia were observed. By cross mating of a isolate from tiger and Nannizzia otae(-) strains, cleistothecia were produced. Both organic iodide and undecylenic acid ointment were effective for therapy. In this paper the dermatophytosis of tiger caused by M. canis is described.
