Greater care and a more thorough approach to intravenous catheter site disinfection may be important for the prevention of catheter related sepsis, especially with coagulase negative staphylocci in preterm infants. The efficacy of skin disinfection was evaluated in preterm infants using a skin swabbing technique after disinfectant exposure. In the first part of the study, 25 peripheral intravas...

background: central venous (cv) catheters play an essential role in the management of critically ill patients in the intensive care unit (icu). cv lines are, however, allied to catheter-associated blood stream infections. bacterial colonization of cv lines is deemed the main cause of catheter-associated infection. the purpose of our study was to compare bacterial colony counts in the catheter s...

Introduction: Oral hygiene aids including toothbrushes if not rinsed in a proper disinfectant can affect oral bacterial translocation and re-infection of the oral cavity due contamination. Aim of the study: The aim of this study was to investigate the survival rate of total oral bacteria on toothbrush and miswak. Material and methods: Totally, 12young individuals with age range 22-28 years and ...

The bacterial flora of blue crabs (Callinectes sapid us) from Chesapeake Bay was examined. Hemolymph of normal, healthy blue crabs was found non-sterile, with total bacterial counts ranging from <100 to >3.0 x 10 5 on a seawater-based medium and 0 to >10 5 on Standard Methods Agar. Counts of 0-10 3 were observed on TCBS agar. Vibrio spp., including Vibrio parahaemolyticus, were the major taxono...

OBJECTIVE To compare the root carious lesion arrest of chlorhexidine (CHX) and silver diamine fluoride (SDF) varnishes and/or sodium fluoride rinses (NaF) in vitro. BACKGROUND Effective and easily applicable interventions for treating root carious lesions are needed, as these lesions are highly prevalent amongst elderly individuals. METHODS In 100 bovine dentin samples, artificial root cari...

OBJECTIVE To assess the relationship of bacterial and fungal contamination on used surgical masks worn by the hospital personnel and microbial air quality in their working wards. METHODS This is a cross-sectional study of 230 used surgical masks collected from 214 hospital personnel, and 215 indoor air samples collected from their working wards to culture for bacterial and fungal counts. This...

Hydrocarbon Utilizing Bacteria (HUB) were isolated at the juvenile and maturity stages from the core and rhizosphere of Tianung 1, Tianung 2 and Cuba 108 accessions of Kenaf (Hibiscus cannabinus) plant grown in a hydrocarbon unimpacted soil in the Niger Delta Area. Standard culture dependent techniques were used for the enumeration of heterotrophic and hydrocarbon-utilizing bacteria while PCR a...

OBJECTIVE To measure effects of Reiki treatments on growth of heat-shocked bacteria, and to determine the influence of healing context and practitioner well-being. METHODS Overnight cultures of Escherichia coli K12 in fresh medium were used. Culture samples were paired with controls to minimize any ordering effects. Samples were heat-shocked prior to Reiki treatment, which was performed by Re...

Bacteriological quality of homologous breast milk Sir, In a recent report Carroll et al.1 showed that the bacterial colony counts of early drip breast milk did not differ from midstream samples and they concluded that early milk was suitable for milk banks and should not be discarded. We report our findings of 'significant' bacterial counts in early milk samples, since we were interested in the...

This study examined the effect of permanent swards and bare soil (by repeated herbicide treatment) on soil microbial counts in Australian cool and warm climate vineyards. In both climates, hot water extractable soil C (HWC) in the vine row was increased by 73% after 3 years of sward development. Most of the soil bacterial counts were greatly decreased by the herbicide treatment and principal co...
