The occurrence of Staphylococcus aureus in the hair of the scalp was investigated in three groups: out-patients, in-patients, and staff of a general hospital. Bacteria were grown from the hair of all the subjects tested and Staphylococcus aureus was the commonest pathogen isolated. It was found more frequently in the hair than in the nose but 20% of hair carriers of Staph. aureus were not nasal...
background staphylococcus aureus (sa) is frequently found on normal human skin and mucous membranes. methicilline resistance s. aureus (mrsa) strains have spread in many hospital isolates world wide since 1970s. hospital personnel tend to have higher colonization rates than the general population. colonized residents and personnel are sources for dissemination of organism. materials and methods...
BACKGROUND Colonization of humans with Staphylococcus aureus is a critical prerequisite of subsequent clinical infection of the skin, blood, lung, heart and other deep tissues. S. aureus persistently or intermittently colonizes the nares of approximately 50% of healthy adults, whereas approximately 50% of the general population is rarely or never colonized by this pathogen. Because microbial co...
BACKGROUND AND OBJECTIVES Staphylococcus aureus (S. aureus) nasal carriage may be responsible for some serious infections in hemodialyzed patients. The main target of this study was to estimate the prevalence of S. aureus nasal carriage in hemodialysis outpatients and medical staff in hemodialysis centers specifically in Fez region. The second target is to identify the risks of colonization, re...
Minimally manipulated nasal secretions, an accessible form of airway surface fluid, were tested against indigenous and added bacteria by using CFU assays. Antimicrobial activity was found to vary between donors and with different target bacteria and was markedly diminished by dilution of the airway secretions. Donor-to-donor differences in electrophoresis patterns of nasal secretions in sodium ...
مقدمه : جراحی رینوپلاستی امروزه یکی از شایعترین اعمال جراحی زیبایی در ایران می باشد که در آن علاوه بر مهارتهای تکنیکی جراح، دارا بودن دانش کامل از وضعیت آناتومیکی ناحیه از اهمیت بسزایی برخوردار است. لذا مطالعه حاضر بر پایه اندازه گیری میزان nasal tip projection در بیماران متقاضی جراحی رینوپلاستی جهت دستیابی به اطلاعات آناتومیک دقیق در بیماران ایرانی طرح ریزی شده است . مواد و روشها: در این مطال...
BACKGROUND Staphylococcus aureus nasal carriage is influenced by multifactorial interactions which are difficult to study in open populations. Therefore, we concomitantly assessed the epidemiological, microbiological, and human-genetic carriage-related factors in a nearly closed population. METHODS In 2006 and 2008, we collected nasal S. aureus strains, human DNA, and epidemiological data fro...
Rabbits were bred at The Rockefeller Institute with special relation to protection from exposure to Bacterium lepisepticum. These healthy rabbits were then submitted to intranasal instillation of a given dose of cultures of Bacterium lepisepticum. The results of the inoculation were various according to the natural degree of resistance of the individual animals. The following graded effects cou...
