Subperiodic, asymptomatic microfilaremia in an adult male from Mysore: a nonendemic area.

Wuchereria bancrofti is found throughout tropics and subtropics like Asia, Pacific islands, Africa, areas of South America and Caribbean basin. In all these areas, except Pacific islands, microfilaria occurs in the periodic form, in which case the microfilaria are found in large numbers in the peripheral blood during night. In the Pacific islands, they occur in the subperiodic form, i.e., microfilaria are present in the peripheral blood at all times and reach the maximum level of parasitemia in the afternoon. Microfilaria of Wuchereria bancrofti and Brugia malayi occurring in India displays a nocturnal periodicity, appearing in large numbers at night. This is the biological adaptation to the nocturnal biting habits of the vector mosquitoes. The maximum density in blood is reported between 10 PM and 2 AM. Here is a case report of asymptomatic microfilaremia showing subperiodicity, which is very unusual in India.

A study of dermatophytes and their in-vitro antifungal sensitivity.

Of the 150 clinically suspected cases of Dermatophytosis studied, majority of the cases were from age group 11-20 and 21-30 (51.4%), Tinea corporis (48.7%) and Tinea capitis (18%) were the commonest clinical types. The isolation rate was 24% (36) of which 19 (52.7%) were Trichophyton rubrum, 11 (30.55%) were Trichophyton mentagrophytes and 4 (11.1%) were Trichophyton violaceum. One isolate each of Microsporum gypseum & Epidermophyton floccosum were obtained. Griseofulvin proved to be the best drug with a sensitivity of 94.4% followed by Miconazole (75% sensitive). Tolnaftate showed a sensitivity of 47.22%. For Clotrimazole only 30.55% of the isolates were sensitive.
