background nasal carriage of staphylococcus aureus is a substantial source of human infections. detection and treatment of nasal carriage in children with methicillin-resistant and multidrug resistant s. aureus (mrsa and mdrsa, respectively) may be an important modality in prevention of infections. objectives this study determined the prevalence, antibiotic resistance patterns and risk factors ...

Staphylococcus epidermidis is the most important member of coagulase negative staphylococci responsible for community and hospital acquired infections. Most clinical isolates of S. epidermidis are resistant to methicillin making these infections difficult to treat. In this study, correlation of methicillin resistance phenotype was compared with methicillin resistance (mecA) gene carriage in 55 ...

conclusions: our findings suggest the possible co-carriage of some blashv genes and aris on the same plasmids harboring the mdr genes. possible role of integrons in dissemination of esbl-encoding blashv genes among esbl-producing k. pneumoniae nosocomial isolates may be inferred. background: some genetic and phenotypic variables are associated among distinct microbial populations. objectives: t...

BACKGROUND The prevalence of infections caused by extended-spectrum beta -lactamase (ESBL)-producing Enterobacteriaceae is increasing worldwide. The influx of these bacteria into hospitals has major implications for infection-control and empirical treatment strategies. METHODS Isolates from 2 patient cohorts--patients with gram-negative bacteremia within 2 days after admission and patients sc...

background: streptococcus pneumoniae is a major cause of childhood morbidity and mortality worldwide . several studies have explored the nasopharyngeal carriage of s. pneumonia in iran. this meta-analysis is aimed at exploring the overall prevalence of nasopharyngeal carriage of s. pneumoniae among healthy children and its resistance to antibiotics. method : we have systematically reviewed publ...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}, $h$-...

Background: Nosocomial infections are an important cause of hospital mortalities. Staphylococcus aureus (S. aureus) carriers among medical staff are an important source of nosocomial infections. The purpose of this study was to investigate the prevalence of the nasal carriers of S. aureus and antibiotic resistance in staff of Nikuee Hospital, Qom, Iran. Materials and Methods: In this cross-s...
