Water is a valued natural resource for the existence of all living organisms. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution in the Unity Road stream segment of Asa River in Ilorin, Nigeria. Juvenile samples of Clarias gariepinu...

Microbial quality of air in a dairy processing plant was evaluated to ascertain the contribution of air as a source of contamination and spoilage of milk and milk products. The mean total aerobic counts obtained in the air by sedimentation method were 32.66 ± 3.82, 25.32 ± 4.17 and 33.36 ± 3.53 cfu/ m in raw milk reception dock, pasteurization room and product preparation room respectively. The...

Multiplex polymerase chain reaction (PCR) and gene probe detection of target lacZ and uidA genes were used to detect total coliform bacteria and Escherichia coli, respectively, for determining water quality. In tests of environmental water samples, the lacZ PCR method gave results statistically equivalent to those of the plate count and defined substrate methods accepted by the U.S. Environment...

This study was conducted to assess the effects of 0.5% Preservative Mixture (PM) containing calcium lactate (40%), sodium diacetate (40%) and sodium chloride (20%) on the microbiological, chemical and sensory quality of chicken meat nuggets stored at 4±2 C and under Modified Atmosphere Packaging o (MAP). There were two experimental groups of samples, namely control and PM-treated. The results s...

The present study was aimed to determine the chemical quality and microbiological safety of some selected milk products retailed in Hisar city of Haryana state. Samples of burfi, paneer, rasogolla and gulabjamun were collected three times from five different sweet shops of Hisar city. The chemical and microbiological analysis of samples were carried out and compared with Indian standard (IS) as...

BACKGROUND The objective of this study was to evaluate the efficacy of Sanitization of Lettuce according to the protocols set forth by Iranian Ministry of Health and Medical Education for reducing populations of total coliform, fecal coliform, and helminth eggs present on lettuce. METHODS In the present study, we determined the load of total coliform, fecal coliform, and parasites of lettuce....

In this research, a lab scale wastewater treatment plant was locally designed as continuous culture of activated sludge and using dual water purification system titanium oxide nanoparticles (TiO2 NPs). Biosynthesis TiO2NPs characterization were done, then nanofilter prepared by tightly wrapping the filter with gauze moistened it 1% TiO2 NPs solution until saturation, control also prepared. Wast...

In this study, we present a method for identifying sources of water pollution and their relative contributions in pollution disasters. The method uses a combination of principal component analysis and factor analysis. We carried out a case study in three rural villages close to Beijing after torrential rain on July 21, 2012. Nine water samples were analyzed for eight parameters, namely turbidit...

On examination, she was febrile, toxic and was complaining of pain in the shoulder joint. The examination of the shoulder joint was normal. Liver was enlarged 5 cm below the right costal margin and was tender. She did not have intercostal tenderness. The white cell count showed a neutrophil leucocytosis with a total count of 16.8 x 10 9 /L. Ultra sound scan of the abdomen revealed a large absce...
