BACKGROUND: Chicken meat is susceptible to microbial and chemical contamination and using antimicrobial agents helps to prolong its shelf-life. OBJECTIVES: This study focuses on the effect of chitosan-based coating and Trachyspermum ammi essential oil on qualitative properties of refrigerated chicken fillet meat. MATERIAL and METHODS: chicken fillets treated with chitosan solution (2 %wv-1) and...
The fate of viruses and pathogens discharged into the ocean in municipal effluent is not known for certain. They probably become inactivated in the same manner that coliform bacteria are—through sedimentation, predation by marine bacteria and filter-feeders, damage by ultraviolet light or abrupt changes from reducing to oxidizing environment, or because of some antiviral agent present in the se...
An investigative study was carried out to determine the bacteriological and physicochemical qualities of borehole and well water samples in Ijebu-Ode, Southwestern Nigeria. Ten water samples each of borehole and well water sources were collected within the geographical location. Physicochemical parameters were determined using standard methods. The total bacterial count was determined by pour p...
AIMS Investigations were carried out to observe the influence of winter/spring and summer periods on the survival of Salmonella typhimurium and indicator bacteria (psychrophilic, mesophilic, coliform and faecal coliform bacteria and faecal streptococci) in the solid fraction of pig slurry from agricultural wastewater treatment plant. METHODS AND RESULTS Leather squares and PVC bottles with op...
BACKGROUND Indiscriminate disposal of untreated wastes which are often heavily laden with sewage microorganisms some of which are pathogenic to humans into aquatic environments near cities could serve as potential dangers to human health. OBJECTIVE A prospective study was undertaken to investigate the scope of potential bacterial pathogens and to assess the extent of pollution of the Douala l...
Multiplex PCR amplification of lacZ, uidA and plc genes was developed for the simultaneous detection of total coliform bacteria for Escherichia coli and Clostridium perfringens, in drinking water. Detection by agarose gel electrophoresis yielded a band of 876 bp for the lacZ gene of all coliform bacteria; a band of 147 bp for the uidA gene and a band of 876 bp for the lacZ gene of all strains o...
hyperbilirubinemia is a common problem during neonatal period especially in preterm neonates. transcutaneous bilirubin measurement (tcb) by special devices had been documented as an effective tool for predicting neonatal jaundice in full term neonate, but for preterm infants the present evidences are controversial. we carried out a prospective study in shariati hospital nicu. 126 paired tcb/tot...
Backgrounds and Objectives: Selection of proper coagulants for turbidity removal and determination of effective methods to reduce coagulants dose and related costs in water treatment plants is of critical importance. The present study investigates the effect of returned sludge on improving the performance of poly-aluminum chloride (PAC) in turbidity, coliform bacteria, heterotrophic bacteria r...
Whether all members of the coliform group of bacteria should be accorded equal sanitary significance has been debated for at least a generation. English and German authorities are disposed to assign special significance to the presence of Escherichia coli, whereas it is the American practice, particularly as applied to water analyses, to consider all coliform bacteria of equal sanitary signific...
A bacteriological study of three ponds in Uegwere Bo-ue community, Khana Local Government Area, of Rivers State, Nigeria were investigated to evaluate the water quality of the ponds. Surface water samples were collected monthly for eight months covering both seasons and evaluated. Bacteriological analyses carried out includes: total heterotrophic bacteria counts(THBC), Total coliform counts(TCC...
