ABSTRACT The persistence and transmission of Aeromonas in a duckweed aquaculture-based hospital sewage water treatment plant in Bangladesh was studied. A total of 670 samples from different sites of the hospital sewage water treatment plant, from feces of hospitalized children suffering from diarrhea, from environmental control ponds, and from feces of healthy humans were collected over a period of three years. In total, 1,315 presumptive Aeromonas isolates were biochemically typed by the PhenePlate rapid screening system (PhP-AE). A selection of 90 representative isolates was further analyzed with PhenePlate (PhP) extended typing (PhP-48), fatty acid methyl ester analysis, and amplified fragment length polymorphism (AFLP) fingerprinting. In addition, the prevalence of the putative virulence factors hemolysin and cytotoxin and the presence of the cytolytic enterotoxin gene (AHCYTOEN) were analyzed. Aeromonas was found at all sites of the treatment plant, in 40% of the samples from environmental control ponds, in 8.5% of the samples from hospitalized children suffering from diarrhea, and in 3.5% of samples from healthy humans. A significantly high number of Aeromonas bacteria was found in duckweed, which indicates that duckweed may serve as a reservoir for these bacteria. PhP-AE typing allowed identification of more than 192 distinct PhP types, of which 18 major PhP types (MTs) were found in multiple sites and during several occasions. AFLP fingerprinting revealed the prevalence of genotypically indistinguishable Aeromonas isolates among certain PhP MTs recovered from different sampling occasions and/or at multiple sites. Hemolytic and cytotoxic activities were observed in 43% of the tested strains, whereas 29% possessed the cytolytic enterotoxin gene AHCYTOEN. Collectively, two specific MTs associated with diarrhea were shown to exhibit high cytotoxicity. Furthermore, all tested isolates of these major types were positive for the cytolytic enterotoxin gene. In conclusion, our data indicate that certain phenotypically and genotypically stable clonal lineages of Aeromonas have persisted in the treatment system for a prolonged period and might spread from the hospitalized children suffering from diarrhea to fish produced for human consumption through the sewage water treatment system.

Estrogens are chemical compounds considered to be endocrine disruptors. They are thought to affect the endocrine system even at low concentrations found in water (ng l-1). The aim of this work was to determine estrogenic compound levels in the rivers in the Brno area. The concentration of 17β-estradiol, ethynylestradiol, estrone and diethylstilbestrol was estimated in the water samples collected in the Svratka and Svitava rivers. Estrogens were isolated from the samples using solid-phase extraction with Oasis HLB cartridges and determined by means of reversed phase HPLC with UV detection. The detection limit of the method used was 6 ng l-1, repeatability expressed as RSD was 11%, and recovery was 87 - 103%. Estrogen values detected ranged in the interval of 6-209 ng l-1, depending on the sampling site. After treatment in the sewage water treatment plant, the water displayed markedly lower levels of estrogenic compounds. The results of the experiment demonstrate that HPLC-UV is a suitable method for determination of low concentrations of estrogens in water. The sewage water treatment plant reduces concentrations of estrogens but not sufficiently to prevent their estrogenic effect on fish.

Sewage Water Treatment

A sewage water treatment plant is necessary to receive and treat waste water (Domestic, Commercial, and Industrial). Its objective is to be convert harmful waste water to safe water environmentally and treated effluent and treated sludge suitable for reuse and disposal such as farm fertilizer. The characteristics of waste water have been performed followed by design of sewage treatment plant. The present study includes design of sewage treatment plant and analysis of waste water – PH value, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Solids (TS), Hardness, Chloride, Acidity, Oil, Fats and grease etc. The sample collection of waste water has been done in many times in a day to obtain an average value of major parameter. Followed by values of this parameter, calculations are done for designing the units of sewage treatment plant and layout is prepared for the same

Here, we report the genome sequence of a Siphoviridae phage named vB_SauS_BaqSau1 (BaqSau1), infecting Staphylococcus aureus. Phage BaqSau1 was isolated from a sewage water treatment plant in Sahagún, Córdoba, Colombia. It has a double-stranded DNA (dsDNA) genome of 44,384 bp with 67 predicted genes, including a lysin containing a CHAP (cysteine, histidine-dependent amidohydrolase/peptidase) domain.

ABSTRACT The ability of Enterococcus faecalis to transfer various genetic elements under natural conditions was tested in two municipal sewage water treatment plants. Experiments in activated sludge basins of the plants were performed in a microcosm which allowed us to work under sterile conditions; experiments in anoxic sludge digestors were performed in dialysis bags. We used the following naturally occurring genetic elements: pAD1 and pIP1017 (two so-called sex pheromone plasmids with restricted host ranges, which are transferred at high rates under laboratory conditions); pIP501 (a resistance plasmid possessing a broad host range for gram-positive bacteria, which is transferred at low rates under laboratory conditions); and Tn916 (a conjugative transposon which is transferred under laboratory conditions at low rates to gram-positive bacteria and at very low rates to gram-negative bacteria). The transfer rate between different strains of E. faecalis under natural conditions was, compared to that under laboratory conditions, at least 105-fold lower for the sex pheromone plasmids, at least 100-fold lower for pIP501, and at least 10-fold lower for Tn916. In no case was transfer from E. faecalisto another bacterial species detected. By determining the dependence of transfer rates for pIP1017 on bacterial concentration and extrapolating to actual concentrations in the sewage water treatment plant, we calculated that the maximum number of transfer events for the sex pheromone plasmids between different strains of E. faecalisin the municipal sewage water treatment plant of the city of Regensburg ranged from 105 to 108 events per 4 h, indicating that gene transfer should take place under natural conditions.
