role of opportunistic fungi in ocular infections in nigeria.the importance of opportunistic fungal pathogens in causing ocular infections is emphasized. a study was conducted over a period of 4 years (1974--1977) to investigate the role of opportunistic fungi in causing mycotic keratitis and to elucidate certain aspects of epidemiology of this disease in nigeria. fifty-nine cases of corneal ulcers of suspected mycotic etiology were investigated. fungal etiology was confirmed in 42 of these cases. the predominant etiological agent was fusarium solani in 1 ...1978745623
etiological agents of otomycosis in nigeria.a total of 159 suspected cases of otomycosis comprising 101 adults and 58 children, 61 males and 98 females were investigated. of these, 36 cases were confirmed specifically of mycotic etiology on the basis of microscopic demonstration of fungal structures in epithelial debris/plugs and positive culture. another 31 cases positive for fungi by culture but negative for direct microscopy were considered of doubtful fungal etiology. the predominant etiological agents in the confirmed cases were aspe ...19892503721
phytochemical and antimicrobial properties of constituents of "ogwu odenigbo", a popular nigerian herbal medicine for typhoid fever.the ethylacetate-insoluble fraction of the methanol extract of "ogwu odenigbo" a popular nigerian traditional herbal medicine for typhoid fever prepared from the stem bark of cleistropholis patens benth, (annonaceae), was separated into 13 semi-characterized constituents by preparatory tlc. the in vitro antimicrobial activities of the 13 fractions were quantitatively and/or qualitatively assessed by the agar well diffusion method using staphylococcus aureus, bacillus subtilis, escherichia coli, ...200111180528
pollution status of swimming pools in south-south zone of south-eastern nigeria using microbiological and physicochemical indices.microbiological and physicochemical characteristics of swimming pools in south eastern states of nigeria (akwa ibom and cross river) were investigated. the bacterial isolates included enterococcus faecalis, clostridium perfringens, bacillus cereus and escherichia coli. others were pseudomonas aeruginosa, staphylococcus aureus, proteus vulgaris and staphylococcus epidermidis, while fungal isolates were penicillium sp, rhizopus sp, aspergillus versicolor fusarium sp, trichophyton mentagrophytes, m ...200415691161
otomycosis in western nigeria.otomycosis is a recognized clinical entity in the tropical regions of the world. however, there is scanty information on this disease in some parts of sub-saharan africa. the aim of this study was to determine the prevalence and pattern of etiological agents of otomycosis in western nigeria. medical records of patients with otomycosis seen in the otorhinolaryngology department of the university college hospital, ibadan from 1996-2005 were reviewed for all essential clinical data. of the 5784 pat ...200818076598
isolation and characterization of microorganisms from instruments used by pedicurists operating within lagos metropolis, nigeria.eight bacterial and five fungal species were isolated from swab samples taken from instruments used by pedicurists operating at three different sites in lagos, nigeria. the bacterial isolates included micrococcus luteus, micrococcus roseus, staphylococcus epidermidis, staphylococcus aureus, hafnia spp, shigella spp, bacillus subtilis and bacillus spp. the five fungal isolates were identified as aspergillus niger, aspergillus flavus, mucor spp, trichophyton spp and candida albicans. the presence ...200415816270
prevalence of otomycosis in malnourished children in edo state, nigeria.out of the total number at 200 suspected cases of otomycoses consisting of 40 malnourished and 160 apparently healthy children examined in this study between the months of july and august in edo state, 64 cases (32%) were identified to be of fungal aetiology on the basis of positive culture and careful microscopic examination. the state at protein energy malnourishment was deterwined using physicians' comments in their case files. the fungal agents isolated were aspergillus niger 28 (43.8%); a. ...19979646512
preliminary investigation of in-vitro antimicrobial activity of two nigerian diospyros species (ebenaceae).the aqueous and alcoholic extracts from the leaves of diospyros bateri and d. monbuttensis were studied for their antimicrobial activities. the alcoholic extracts of the two diospyros spp. showed strong antibacterial activity against a wide range of gram-positive and gram-negative bacteria, while only the aqueous extract of d. bateri showed antibacterial activity against all the bacteria tested. the two fungi included in the study aspergillus niger and candida albicans were found to be resistant ...19882845757
