“…Many older and less rigorous studies did not use multivariate regression and did not adjust for individual factors such as age, socioeconomic status, or sanitation access. Additionally, several studies did not report the time and duration of the study, which are important factors for studies on diarrheal diseases since they are subject to seasonal effects (Jagai et al, 2012) and seasonality is known to affect source water quality and choice of source (Kostyla et al, 2015).…”

Many studies have found that household access to water supplies near or within the household plot can reduce the probability of diarrhea, trachoma, and other water-related diseases, and it is generally accepted that on-plot water supplies produce health benefits for households. However, the body of research literature has not been analyzed to weigh the evidence supporting this. A systematic review was conducted to investigate the impacts of on-plot water supplies on diarrhea, trachoma, child growth, and water-related diseases, to further examine the relationship between household health and distance to water source and to assess whether on-plot water supplies generate health gains for households. Studies provide evidence that households with on-plot water supplies experience fewer diarrheal and helminth infections and greater child height. Findings suggest that water-washed (hygiene associated) diseases are more strongly impacted by on-plot water access than waterborne diseases. Few studies analyzed the effects of on-plot water access on quantity of domestic water used, hygiene behavior, and use of multiple water sources, and the lack of evidence for these relationships reveals an important gap in current literature. The review findings indicate that on-plot water access is a useful health indicator and benchmark for the progressive realization of the Sustainable Development Goal target of universal safe water access as well as the human right to safe water.

“…Previous research indicates that drinking water quality is influenced by changing weather patterns, with microbial water quality usually deteriorating in the rainy season. 14,15 In general, high levels of precipitation raise the groundwater table and increase susceptibility to pollution. 16 Furthermore, little is known about the seasonality of packaged water, as previous studies have been cross-sectional.…”

“…16 Furthermore, little is known about the seasonality of packaged water, as previous studies have been cross-sectional. 6,14,17 Our objectives were to compare drinking and domestic water sources and water quality in Port Harcourt between the dry and rainy seasons, specifically evaluating the effects of flooding, rain, and higher water tables on water quality and investigating the influences of sanitation, drainage, and land use on groundwater quality. Given the high prevalence of on-site sanitation systems, identifying patterns in contamination could be helpful for identifying potential hazards and mitigating risks to water quality in non-piped water sources in the Port Harcourt region.…”

Abstract. We compared dry and rainy season water sources and their quality in the urban region of Port Harcourt, Nigeria. Representative sampling indicated that municipal water supplies represent < 1% of the water sources. Residents rely on privately constructed and maintained boreholes that are supplemented by commercially packaged bottled and sachet drinking water. Contamination by thermotolerant coliforms increased from 21% of drinking water sources in the dry season to 42% of drinking water sources in the rainy season (N = 356 and N = 397). The most significant increase was in sachet water, which showed the lowest frequencies of contamination in the dry season compared with other sources (15%, N = 186) but the highest frequencies during the rainy season (59%, N = 76). Only half as many respondents reported drinking sachet water in the rainy season as in the dry season. Respondents primarily used flush or pour-flush toilets connected to septic tanks (85%, N = 399). The remainder relied on pit latrines and hanging (pier) latrines that drained into surface waters. We found significant associations between fecal contamination in boreholes and the nearby presence of hanging latrines. Sanitary surveys of boreholes showed that more than half were wellconstructed, and we did not identify associations between structural or site deficiencies and microbial water quality. The deterioration of drinking water quality during the rainy season is a serious public health risk for both untreated groundwater and commercially packaged water, highlighting a need to address gaps in monitoring and quality control.

САЖЕТАКПрисуство Klebsiella pneumoniae (K. pneumoniae) у пијаћим и површинским водама представља индикатор фекалне контамина-ције хуманог и животињског порекла. K. pneumoniae има способност да стекне и пренесе гене резистенције. Изолати из животне сре-дине могу представљати резервоар ових гена који се могу пренети и на друге бактеријске врсте. Циљ рада је изолација, идентификација и тестирање антибиотске осетљивости K. pneumoniae из пијаћих и површинских вода. Про-спективна студија (спроведена од 1. октобра до 31. децембра 2015. године) испитала је 1276 узорака воде. Узорци су обрађени мем-бран-филтерском методом. За идентифика-цију K. pneumoniae коришћени су стандардни биохемијски тестови. Осетљивост на анти-биотике је тестирана диск-дифузионом мето-дом. K. pneumoniae је пронађена у 2,98% (38/1276) узорака, oд којих су 42,11% (16/38) били узорци површинских, а 57,89% (22/38) узорци пијаће воде. Teстирани изолати су били резистентни на ампицилин, док рези- ABSTRACTPresence of Klebsiella pneumoniae (K. pneumoniae) in drinking and surface water indicates fecal contamination of human or animal origin. K. pneumoniae has the ability to acquire and transfer resistance genes. Isolates found in the environment may represent a reservoir of these genes, which can be transmitted among different bacterial species. The aim of the study was identification and testing susceptibility of K. pneumoniae to antibiotics after isolation from drinking and surface water. Prospective study (conducted from October the 1 st 2015 to December the 31 st 2015) included 1276 samples of drinking and surface water. The samples were processed by membranefilter technique. Standard biochemical tests were used for identification of K. pneumoniae. Antimicrobial susceptibility was determined by diskdiffusion method. K. pneumoniae was found in 2.98% (38/1276) of samples, from both surface 42.11% (16/38) and drinking water 57.89% (22/38). Tested strains were resistant to ampicillin, but resistance to other antibiotics was not confirmed. K. pneumoniae could be found in drinking , која се описује као једна од најчешћих узрочника болничких и ванбол-ничких инфекција, јер се лако преноси кон-тактом и путем заражене хране и воде 4 . Ова бактерија има велику способност стицања и преноса гена резистенције 10,11 . Изолати који се нађу у животној средини, представљају резер-воар тих гена, који се даље могу преносити и на друге бактеријске врсте. Тиме се рези-стентни сојеви могу јавити, не само у болни-чким срединама, где су најчешћи услед се-лективног притиска насталог нерационалном употребом антибиотика, већ и у општој попу-лацији [10][11][12][13][14] . Лечење инфекција узрокованих ре-зистентним сојевима је све већи јавно-здрав-water despite the purification and chlorination. In our study strains isolated from drinking and surface water were susceptible to commonly used antibiotics, without any markers of acquired resistance.Дејан Добријевић, Aника Трудић, Владан Борчић, Maja Бекут 2 стенција на друге антибиотике није забеле
