This study clarifies the important role of nanofibers produced from polyacrylonitrile after reinforcement with iron nanoparticles (γ-Fe2O3), to expand applications these fibers and combine their ability remove Nickel (II) aqueous solutions pollutants such as total suspended solids, nitrogen, chemical oxygen demand, cyanide well killing bacteria in wastewater. The results absorption treatment so...

objective: to estimate incidence of reactive thrombocytosis among febrile infants and assess utility of platelet count as a potential predictor and diagnostic tool of serious bacterial infection .design:prospective non randomized study conducted between april 2011 to march 2012setting: tertiary care pediatric unit.inclusion criteria:all infants 30 to 89 days of age, admitted with rectal tempera...

background and objectives: pulsed electric field (pef) is a novel emerging technology which is believed to have the potential to substitute conventional thermal pasteurization (htst). in the current study pef was compared with htst based on microbial inactivation and quality attributes. materials and methods: juice was prepared by extracting it from semirum apples. they were chilled to 4ºc over...

AIM To study the effect of preputial washing on bacterial load, preservability and semen quality in Murrah buffalo bulls. MATERIALS AND METHODS A total of 36 collections of three Murrah buffalo bulls maintained at Artificial Breeding Research Centre, ICAR-National Dairy Research Institute, Karnal, were collected at weekly intervals from each bull without preputial washing and latter ejaculate...

background and aims: in iran herbal water and dried herb are as traditional medicinal and are consumed widely. therefore, microbial evaluation of these products in term of public health is important. the aim of the present study was to study the contamination of some dried medical plants and distillates in the groceries of shahrekord city. methods: in this descriptive study, 35 samples of herba...

Analysis of 100 bagged lettuce and spinach samples showed mean total bacterial counts of 7.0 log(10) CFU/g and a broad range of < 4 to 8.3 log10 CFU/g. Most probable numbers (MPN) of > or = 11,000/g coliforms were found in 55 samples, and generic Escherichia coli bacteria were detected in 16 samples, but no E. coli count exceeded 10 MPN/g.

The effect of the addition of 2, 3, 5, 7 and 10% respectively of propionic acid on known numbers of bacteria added to or contained in carcass meal was examined. Escherichia coli was totally inhibited by 2% propionic acid, while 5% of the acid both inhibited Salmonella typhimurium and brought about a 74,7% reduction in the total aerobic bacterial count.

Research involving bacterial pathogens often requires enumeration of bacteria colonies. Bacterial colony enumeration is an essential tool for many widely used biomedical assays. Bacterial colony enumerating is a low throughput, time consuming and labor intensive process. Since there might exist hundreds or thousands of colonies on a Petri dish, and the counting process is often manually perform...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.
