The effect of oxidative stress exerted by 0.03% crystal violet, 0.3% bile salt, 4.0% NaCl and 8% ethanol on the survival and production of virulence factors among Acinetobacter haemolyticus isolates obtained from wastewater and river water samples was investigated. Though generally there was insignificant lethal effect against all the isolates, crystal violet exerted the highest lethal effect f...

It is generally accepted that the main route for human pharmaceuticals to the aquatic environment is via sewage treatment plants receiving wastewater from households and hospitals. We have analysed pharmaceuticals in the effluent from a wastewater treatment plant serving about 90 bulk drug manufacturers in Patancheru, near Hyderabad, India--a major production site of generic drugs for the world...

BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...

introduction: recently, the accreditation program has been used increasingly by an emphasis on patient safety. in iran, efforts have been made to establish the accreditation program. in 2011, it replaced previous standards of traditional evaluation system. as the impact of accreditation plan need internal self assessment against minimal standards, this study aimed to survey the readiness of sel...

introduction : it is clear that if the discharge process takes less time and the patient leaves the hospital bed earlier, the length of hospitalization, and consequently, the waiting time for admission decreases. therefore, the method of use of treatment facilities is somewhat improved. the hospital discharge process, from when the discharge authorization is issued until the patient leaves the ...

(Received: June 6, 2013; Accepted in Revised Form: Nov. 13, 2013) Abstract: Although medical wastewaters are considered as hazardous, little attention is paid to their proper management and disposal. This study conducted on two typical educational hospitals with 300 and 220 beds capacity for parasite cysts and Ova reduction by the hospital wastewater treatment plants. Samples were collected fro...

Introduction: Large quantities of antimicrobials are used in hospitals for patient care and disinfection. Antibiotics are partially metabolized and residual quantities reach hospital wastewater, exposing bacteria to a wide range of biocides that could act as selective pressure for the development of resistance. Methodology: A cross-sectional study was conducted between December 2010 and Februar...
