We present here a case report of a suspected leptospiral infection in a Nepali soldier, and the results of a serological survey of 188 residents of Eastern Nepal that indicate the infection may be common there. This is the first report of leptospirosis in Nepal although it is known to affect man and animals in most of the temperate and tropical regions of the world, and apparently occurs widely in India (Das Gupta, 1938; Khanna & Iyer, 1971).
The common etiological agents of onychomycosis are dermatophytes, molds and yeasts. A mycological nail investigation of onychomycosis using direct microscopy and culture was conducted by the Mycology Unit, Department of Medical Microbiology, University of Malaya from March 1996 to November 1998. The study involved 878 nail clippings or subungal scrapings from subjects with onychomycosis. On direct microscopy examination, 50% of the specimens were negative for fungal elements. On culture, 373 specimens had no growth; bacteria were isolated from 15 nail specimens. Among the 490 specimens with positive fungal cultures, 177 (36.1%) were dermatophytes, 173 (35.5%) were molds and 130 (26.5%) were Candida. There were 2% (10/490) mixed infections of molds, yeasts and dermatophytes. Trichophyton rubrum (115/177) and Trichophyton mentagrophytes (59/177) were the main dermatophytes isolated. The molds isolated were predominantly Aspergillus niger (61/173), Aspergillus nidulans (30/173), Hendersonula toruloidea (26/173) and Fusarium species (16/173). 96.9% of the Candida species identified were Candida albicans.
To enhanced the development and reproduction of Eri silkworm incorporation of Coal Flyash Liquid (CFL) in their natural diet was developed to evaluate the growth and fecundity rate of eri silkworm. energy dispersive analysis of castor leaves treated with CFL at 10% concentration revealed the presence of five major minerals viz., magnesium (Mg), silica (Si), chlorine (Cl), potassium (K) and calcium (Ca). While CFL incorporated castor leaf enhanced the pupation rate, shell weight, cocoon shell ratio, fecundity and egg hatchability of the silkworm. In contrast, pupal weight was increased at lower concentration of CFL with a weight of 2.39 mg. A significant difference was observed in rearing performance of eri silkworm at different concentrations of CFL incorporated castor leaf. Relative growth rate of the eri silkworm was increased to 84% when larvae treated with CFL at 5% concentration. Further, CFL at the concentration of 5% enhanced the seed germination percentage and at the higher concentration of 10% increased the root-shoot ratio, relative water content and vigour index of cucumber. Similar response of increase in studied growth parameters was also observed in radish seedlings when treated with CFL. The physiochemical properties of CFL amended soil (5%) showed that available phosphorous level and potassium level was increased respectively to 9.52% and 53.92% in comparison to control. It could be concluded that minerals present in CFL may be influential and responsible for the growth of eri silkworm and seedling of cucumber and radish.
The distribution of Candida species was examined using 1114 yeasts isolated from various clinical specimens. The isolates were identified by germ tube test, hyphal/pseudohyphae and chlamydoconidia production and carbohydrate assimilation test using ten carbohydrates (glucose, sucrose, trehalose, cellobiose, arabinose, galactose, mannitol, raffinose, lactose and maltose). Among the 1114 isolates studied, 9 species of Candida were identified and the relative frequency of isolation was C. albicans (44.2%), C. parapsilosis (26.0%), C. tropicalis (17.7%), C. glabrata (9.6%), C. krusei (1.2%), C. rugosa (0.6%), C. guilliermondii (0.2%), C. lusitaniae (0.08%) and C. kefyr (0.08%). Non-C. albicans was the most common Candida species isolated from blood, respiratory system, urine and skin. The isolate from vaginal swabs was predominantly C. albicans. 82.2% of C. glabrata and 64.2% of C. krusei isolated in this study were from vaginal swabs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
