We report here the draft genome sequence of the first isolated NDM-4-producing Escherichia coli strain, isolated from sewage water at a North Indian hospital. The genome has an assembly size of 5,076,053 bp, arranged in 129 contigs, with 5,271 genes and a G+C content of 50.47%.
Pseudomonas aeruginosa phage phiIBB-PAA2 is a broad-host-range virus isolated from raw hospital sewage (Porto, Portugal). This phage has a terminally redundant (183 bp), 45,344-bp double-stranded DNA (dsDNA) genome encoding 66 coding sequences (CDSs) and 3 tRNAs. It belongs to the family Podoviridae and the genus Luz24likevirus.
Multidrug resistant microbes present in the environment are a potential public health risk. In this study, we investigate the presence of New Delhi metallo-β-lactamase 1 (NDM-1) producing bacteria in the 99 water samples in Beijing City, including river water, treated drinking water, raw water samples from the pools and sewage from 4 comprehensive hospitals. For the bla NDM-1 positive isolate, ...
In June and July of 1858, oppressed by one of the hottest summers on record—a summer which, among other things, required parliamentary staff to hang lime-soaked cloths across the riverside windows of the Houses of Parliament to filter out the stench of a 20 per cent concentration of sewage in the Thames—the United Kingdom parliament agreed to the passage of a Medical Act. The Act gave statutory...
Wastewater consists of a complex mixture of substances. During wastewater treatment these harmful substances can be eliminated or degraded. However, persistent compounds released with the treated sewage effluents enter the environment and pose a risk to animal and human life. To determine the potential risks involved, screening tests are needed to monitor wastewater for potential toxic contamin...
The health impact of utilization of raw domestic sewage for vegetable cultivation in the suburbs of Asmara, Eritrea, was assessed. Results showed heavy contamination of vegetables by fecal coliforms and Giardia cysts as well as other pathogenic bacteria such as Shigella and Salmonella. Stool samples from 75 occupationally exposed farmers revealed that 45% of them were harboring Giardia cysts. D...
A study was undertaken to assess the health impact of utilization of the raw domestic sewage for vegetable cultivation in the suburbs of the capital city of Asmara, Eritrea. Standard techniques were adopted for the analysis of the samples. Results showed heavy contamination of vegetables by faecal coliforms as well as with Giardia cysts. Stool samples of 75 farmers who were occupationally expos...
Microalgal blooms can result from anthropogenic nutrient loadings in coastal ecosystems. However, differentiating sources of nutrients remains a challenge. The response of phytoplankton and benthic microalgae (BMA) to nutrient loads was compared across tropical tidal creeks with and without secondary treated sewage. Primary productivity in the water column was limited by nitrogen availability i...
Sewage is a kind of ideal low-temperature heat sources. Sewage heat source pump system uses heat energy in sewage, and it is a method of utilizing sewage resources. In this article we analyze sewage’s characteristics and sewage source heat pump system; introduce its practical applications in sewage treatment plants in China, analyze its technical and economic characteristics, and discuss its ap...
