Escherichia coli, is intimately associated with both human health and water sanitation. E. coli isolates from water can either be (i) host associated commensals, indicating recent faecal contamination; (ii) diarrheal pathogens or (iii) extra-intestinal pathogens that pose a direct health risk; or (iv) free-living. In this study we genetically characterised 28 E. coli isolates obtained from treated drinking water in south eastern Australia to ascertain their likely source. We used full genome sequencing to assign the isolates to their phylogenetic group and multi-locus sequence type...

The International Agency for Research on Cancer (IARC) has classified two liver flukes as carcinogenic to humans (Group 1): Opisthorchis viverrini in 1994 and Clonorchis sinensis in 2009. This review is focused on O. viverrini, the most studied of these two trematodes, which infects nearly 10 million people in Southeast Asia. The life cycle involves two intermediate hosts living in fresh water: a snail of the genus Bithynia and a ciprinid fish. The definitive hosts (human, cat, dog) become infected by ingesting raw fish containing metacercariae, the infective stage of the parasite...

Triclosan (TCS) is an antimicrobial ingredient found in personal care products that include soaps, shampoos, and other sanitation goods. TCS is moderately hydrophobic and has been shown to be resistant to wastewater treatment and thus accumulates in biosolids. Biosolids are commonly applied to agricultural land but little is known about the risk that TCS in biosolids poses to soil fungal communities following land application. The purpose of this study was to characterize the effects of TCS on the symbiotic colonization of roots in three field crops (soybean, corn, and spring wheat) by arbuscular mycorrhizal fungi (AMF) in soils amended with four different types of biosolids (liquid, dewatered, composted, alkaline and hydrolyzed)...

BACKGROUND: Economic burden to households due to out-of-pocket expenditure (OOPE) is large in many Asian countries. Though studies suggest increasing household poverty due to high OOPE in developing countries, studies on association of multidimensional poverty and household health spending is limited. This paper tests the hypothesis that the multidimensionally poor are more likely to incur catastrophic health spending cutting across countries. DATA AND METHODS: Data from the Poverty and Vulnerability Assessment (PVA) Survey carried out by the International Center for Integrated Mountain Development (ICIMOD) has been used in the analyses...

Favus is an uncommon form of tinea capitis (TC) currently seen in geographic areas with poor sanitation and limited access to health care such as emerging nations. Several variants of this condition have been described including one exhibiting a plaque composed of parchmentlike material. The makeup of this plaque has not been described. Tinea capitis is rare in adults, particularly when the infectious agent is Trichophyton rubrum, and affected patients often exhibit comorbidities associated with diminished immune surveillance...

Porcine Epidemic Diarrhea Virus (PEDV) was the first virus of wide scale concern to be linked to possible transmission by livestock feed or ingredients. Measures to exclude pathogens, prevent cross-contamination, and actively reduce the pathogenic load of feed and ingredients are being developed. However, research thus far has focused on the role of chemicals or thermal treatment to reduce the RNA in the actual feedstuffs, and has not addressed potential residual contamination within the manufacturing facility that may lead to continuous contamination of finished feeds...

Occupational irritant contact dermatitis (ICD) affecting the hands is a common and difficult-to-manage condition. Occupations that necessitate contact with harsh chemicals, use of alcohol-based disinfectants, and frequent hand washing elevate the risk of ICD. Management strategies that do not adequately prevent accumulated damage and repair skin, can develop into chronic dermatoses which negatively impact work productivity and quality of life. A 2-step skin-care regimen (Excipial Daily Protection Hand Cream (EP) and Excipial Rapid Repair Hand Cream (ER), Galderma Laboratories, L...

This study, conducted in 40 selected upazilas covering four hydrological regions of Bangladesh, aimed at determining the risk of selected shallow tubewells (depth<30m) used for drinking purpose (n=26,229). This was based on WHO's sanitary inspection guidelines and identifying the association of sanitary inspection indicators and risk scores with microbiological contamination of shallow tubewells. The main objective of the study was to observe the seasonal and regional differences of microbial contamination and finally reaching a conclusion about safe distance between tubewells and latrines by comparing the contamination of two tubewell categories (category-1: distance ≤10m from nearest latrine; n=80 and category 2: distances 11-20m from nearest latrine; n=80) in different geographical contexts...

Studies assessing the impacts of school-based water, sanitation, and hygiene (WASH) interventions have revealed inconsistent improvements in pupils' health and educational outcomes. This may be in part due to suboptimal project fidelity or adherence. As part of a matched-control trial of a comprehensive school-based WASH project in Mali, we measured the degree to which schools met four prespecified WASH targets, comprised of 15 criteria, 0-3 years after program implementation. We compared achievement of the targets and criteria between beneficiary and matched control schools, and compared achievement within beneficiary schools at baseline and at follow-up visits...

Changes in seroprevalence of cysticercosis diagnosed in Chandigarh, India between 1998 and 2014 were investigated by extraction and analysis of data from records held at the Postgraduate Institute of Medical Education and Research in Chandigarh. Among the total number of samples for which cysticercosis had been suspected during this period (N = 9650), 1716 (17·8%) were seropositive. Adults were more likely to be seropositive than children, and women were more likely to be seropositive than men. In addition to there being fewer patients with suspicion of cysticercosis over the data analysis period, the proportion of patients seropositive also reduced significantly...

The adaptation of the membrane distillation process as a low-cost and sustainable approach to biosolids drying and stabilization is investigated, which may have application in container-based sanitation systems proposed in low-income urban regions. Three-layer laminated, breathable, hydrophobic membranes enclose the biosolids, facilitating drying but preventing transport of contaminants. The membranes used in this process are non-wetting with pore spaces that only allow vapor transport. Water vapor can be expelled due to a moderate vapor pressure gradient...
