Abstract Many parasites and pathogens are transmitted via water, including through faecal contamination of water sources. Yet water is essential for survival, and some species gain nutritional and other benefits from coprophagy. We investigated how primates balance the risks of faecal pathogen transmission with potential benefits of faeces ingestion in their selection of water sources by conducting behavioural experiments with five species of lemurs (Family Lemuridae) in captivity. Subjects were given a choice between clean water and water ‘contaminated’ with disinfected faecal material, which

Microbial contamination of small streams in agricultural areas was monitored for two years. Microbiological indicators of faecal pollution (faecal coliforms, <I>Escherichia coli</I> and intestinal enterococci were detected by standard methods based on the cultivation of bacteria on selective media). The obtained results showed that running contamination of streams from agricultural areas was not extremely high, but it showed marked seasonal fluctuations (the average values and maximal values revealed great differences). Microbial contamination also increased several times in relati

AbstractWastewater containing human sewage is often discharged with little or no treatment into the Antarctic marine environment. Faecal sterols (primarily coprostanol) in sediments have been used for assessment of human sewage contamination in this environment, butin situproduction and indigenous faunal inputs can confound such determinations. Using gas chromatography with mass spectral detection profiles of both C27and C29sterols, potential sources of faecal sterols were examined in nearshore marine sediments, encompassing sites proximal and distal to the wastewater outfall at Davis Station.

The faecal contamination of drinking water sources can lead to waterborne disease outbreaks. To estimate a potential risk for waterborne infections caused by faecal contamination of drinking water sources, knowledge of the pathogen concentrations in raw water is required. We suggest a novel approach to estimate pathogen concentrations in a drinking water source by using microbial source tracking data and fate and transport modelling.

In risk assessment, great advances have been made in recent years with the introduction of microbial source tracking (MST) techniques.

SUMMARYEarlier studies showed that the minimum infective dose (>106 organisms) of a virulent strain of Fusobacterium necrophorum could be greatly reduced by suspending the fusobacteria in sub-lethal doses of cultures of other bacteria such as Escherichia coli before inoculating mice subcutaneously.In the present study the infective dose of the same strain of F. necrophorum was reduced by a factor of >103 by suspending the fusobacteria in sub-lethal doses of 5% homogenate of gaur or wallaby faeces. Sterile faecal filtrate had no such effect. The sites of low grade infection produced by th

Access to clean and safe drinking water still remains a major challenge in the developing world, causing public health risks in terms of waterborne infections, especially in rural areas of sub-Saharan Africa. This study aimed to track and detect enteric pathogens (Salmonella enterica subsp. enterica serovar Typhimurium str. LT2, Shigella flexneri, and Campylobacter jejuni subsp. jejuni) in rural water sources. It also sought to establish a correlation between these pathogens and the sources of faecal pollution. Multiplex qPCR and specific primers and probes were used for detection and tracking

The health risk posed by effluent irrigation in a semi-arid area of Portugal was assessed. The residual contamination found on lettuces spray-irrigated with the effluent from a conventional trickling filter plant was compared to that of locally marketed lettuces and to the ICMSF (1974) standards. The 2-year study indicated initially high levels of faecal indicator bacteria on lettuces, but after irrigation ceased, the restricting climatic conditions sufficed to decontaminate them to local market quality within 5 days when no salmonellae could be detected. Although high, E.coli I levels were wi

Tree frogs commonly access drinking water tanks; this may have human health implications. Although amphibians might not be expected to host mammalian faecal indicator bacteria (FIB), it is possible that they may have human FIB on their skin after exposure to human waste. We collected faeces and skin wash from green tree frogs (Litoria caerulea) from a natural environment, a suburban site, and a suburban site near a creek occasionally contaminated with sewage effluent. We used molecular techniques to test for FIB that are routinely used to indicate human faecal contamination. Enterococci coloni

Toxocariasis is one of the most important parasitic zoonoses affecting human health. The main source of toxocariasis in humans is dog and cat faeces, which are primarily responsible for the contamination of urban areas with Toxocara spp. eggs. In this study, the relationship between dog or/and cat faeces and contamination of sand playgrounds in public parks with Toxocara spp. eggs was investigated. A total of 596 sand and 276 faecal samples (148 dog and 128 cat faeces samples) were collected from 52 public parks in Samsun. Toxocara spp. eggs were identified in 7% of sand samples, 33% of cat fa

Ground water is one of the most important natural resource next to air being essential for life. Quality of ground water depends upon natural process, such as wet/dry condition, salts, many geogenic and anthropogenic activities. Among all contamination ground water is more susceptible to microbial contamination. According to WHO report about 80% of all diseases in human being are caused due to drinking water contaminated by bacteria of faecal origin.

Viral extraction was performed on dissected tissues and the clinically most important enteric viruses (hepatitis A virus, small round structured virus, rotavirus and enterovirus) were searched for by RT-PCR and hybridization. Among the 104 samples analysed, 66% were contaminated by at least one virus and 34% were negative for any virus. The two sites regularly contaminated by faecal coliforms had the highest percentage of viral contamination and HAV was detected only in these sites. However, sampling site

Traditionally, water quality regulation and protection of public health has relied on culture-based methods that quantify faecal indicators such as the coliforms. Since Escherichia coli represents over 97% of the thermotolerant coliforms, it has been used extensively as a key indicator of faecal contamination in water testing industry. However the presence of E. coli or other coliforms (and more recently enterococci) does not provide any information regarding the source of contamination and therefore is not always an effective indicator of actual risk to humans.
