RESUMEN
Nakuru North sub-county is a peri-urban area which has both dry and wet seasons. Its residents rely mostly on untreated water sources for daily water needs due to unreliable water supply from the urban council. However, this water has not been evaluated on its quality despite residents solely depending on it. This study was aimed at determining the physico-chemical and bacteriological quality of water drawn from River Kandutura and water taps in Nakuru North sub-county. In addition, the study was aimed at carrying out sensitivity test of the isolates to antibiotics and determining effectiveness of solar disinfection in water treatment. A total of 510 water samples; river (255) and taps (255) were collected and analyzed between January and December 2013. Antimicrobial sensitivity test was carried out using Kirby Bauer disk diffusion test. Out of five hundred and ten (510) samples examined for microorganisms, 36.86 % (188/510) were positive for E. coli, Shigella and Salmonella. Water used by Nakuru North sub-county residents is highly contaminated thus posing public health risk. Solar disinfection experiment indicated a possibility of effective decontamination of water up on exposure to sun light for 3-5 h. E. coli showed the highest resistance (26.3 %) followed by Salmonella (17.4 %) while Shigella showed the least (17.1 %). However, there was no significant deference (p=0.98) in resistance among total coliforms, Total heterotrophic and Salmonella at 0.05 level of significant. There is a need to enforce laws and policies on proper waste disposal as part of water pollution control.
RESUMEN
BACKGROUND: Tinea capitis is a common infection especially in poor resource settings. This study was aimed at determining the prevalence Tinea capitis in children from selected schools from an urban slum in Nairobi city of Kenya. METHODS: A cross-sectional study was carried out in 150 school going children during the period between May and September 2013. A questionnaire was administered and cultures of scalps, skin scrapping/hair stubs samples were performed and the etiological agents identified and confirmed. RESULTS: In a total of one hundred and fifty (150) children recruited 89 (59.3%) were males and 61 (40.7%) females aged between 3 and 14 years. The overall prevalence rates in dermatophytes infection was 81.3% (122/150) with etiological agents consisting Trichophyton spp. (61.3%), Microsporum spp. (13.3%) and Epidermophyton spp. (7.3%) infections with infections occurring either singly (56%), duo (38%) or tipple co-infections (6%). CONCLUSION: This study demonstrates a high prevalence of Tinea infections with Trichophyton tonsurans as the predominant etiological agent in school going children of the urban slums of Nairobi.
