The GeneOhm MRSA assay detects nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA). We compared the use of seeded swabs with liquid Stuart's medium and that of seeded swabs with Amies gel for the assay. Overall, the swabs with liquid Stuart's medium detected significantly greater numbers of MRSA than the swabs with Amies gel (P = 0.0003).
Four swab materials were evaluated for their efficiency in recovery of Bacillus anthracis spores from steel coupons. Cotton, macrofoam, polyester, and rayon swabs were used to sample coupons inoculated with a spore suspension of known concentration. Three methods of processing for the removal of spores from the swabs (vortexing, sonication, or minimal agitation) and two swab preparations (premo...
Staphylococcus aureus carriers are at higher risk of S. aureus infection and are a reservoir for transmission to others. Detection of nasal S. aureus carriage is important for both targeted decolonization and epidemiological studies. Self-administered nasal swabbing has been reported previously, but the effects of posting swabs prior to culture on S. aureus yield have not been investigated. A l...
شپشه ی دندانه دار برنج oryzaephilus surinamensis l. یکی از مهمترین آفات برنج در طول دوره انبارداری این محصول می باشد. با توجه به ماهیت این آفت، کنترل آن همواره سخت بوده و بکارگیری حشره کش ها و اسانس های گیاهی از گیاهان دارویی با خاصیت دورکنندگی در منابع مختلف علیه این آفت گزارش شده است. ما خاصیت کشندگی و دورکنندگی به لیمو aloysia citriodora، زنیان carum copticum ،لعل کوهستان oliveria decumbens،...
BACKGROUND Modern operating rooms are considered to be aseptic environments. The use of surgical mask, frequent air exchanges, and architectural barriers are used to reduce airborne microbial populations. Breaks in surgical technique, host contamination, or hematogenous seeding are suggested as causal factors in these infections. This study implicates contamination of the operating room air as ...
A study was designed to assess the performance of various swabs and transport media routinely used to collect specimens submitted for Bordetella culture and PCR. Calcium-alginate swabs inhibited the PCR. No inhibition was detected in any PCRs with dacron or rayon swabs. All swab materials performed similarly for recovery of Bordetella pertussis in culture. The Amies with charcoal transport syst...
Among 228 women with gonorrhoea (confirmed by culture), swabs taken blindly from the anal canal gave positive results in 26.3% and those taken from the rectum under direct vision in 27.6%. Swabs from both sites gave positive results in 23.2% of patients, from the anal canal alone in 3.1%, and from the rectum alone in 4.4%. Thus, culuture of anal canal swabs seems to give as reliable results as ...
BACKGROUND Ebola virus emerged in West Africa in December 2013. The high population mobility and poor public health infrastructure in this region led to the development of the largest Ebola virus disease (EVD) outbreak to date. METHODOLOGY/PRINCIPAL FINDINGS On September 26, 2014, China dispatched a Mobile Biosafety Level-3 Laboratory (MBSL-3 Lab) and a well-trained diagnostic team to Sierra ...
اسانس های گیاهی با اثرات شناخته شده ای که روی آفات گذاشته اند، می توانند جایگزین مناسبی برای آفت کش های شیمیایی رایج باشند. در این تحقیق، اثرات سمیت تدخینی، تماسی و دورکنندگی اسانس صمغ، میوه و برگ بنهpistacia atlantica desf. subsp. kurdica (zohary) rech. f. روی حشرات کامل سوسک چهارنقطه ای حبوبات callosobruchus maculatus (fabricius, 1775) و شناسایی ترکیبات، اثرات سمیت تدخینی، تماسی و دورکنندگی ا...
