Development of antimicrobial resistance has been assigned to excess and misuse of antimicrobial agents. Staphylococci are part of the normal flora but are also potential pathogens that have become essentially resistant to many known antibiotics. Resistances in coagulase negative staphylococci (CoNS) are suggested to evolve due to positive selective pressure following antibiotic treatment. This ...

BACKGROUND Increasing multidrug resistance in gram-negative bacilli (GNB) infections poses a serious threat to public health. Few studies have analyzed co-resistance rates, defined as an antimicrobial susceptibility profile in a subset already resistant to one specific antibiotic. The epidemiologic and clinical utility of determining co-resistance rates are analyzed and discussed. METHODS A 1...

conclusions the clinical klebsiella strains isolated from lahore region, pakistan exhibited resistance to most commonly used antibiotics, which can be a serious threat to public health. the study reported some potential actinomycetes strains, which exhibit promising activity against multidrug resistant klebsiella strains. results the isolated klebsiella strains showed resistance against most of...

nosocomial infections of multidrug-resistant pseudomonas aeruginosa (mdrpa) are a growing concern in hospitalized patients in burn centers. the aim of this study was to investigate the flagellin profiling and antibiotic susceptibility of p. aeruginosa isolated from burn wound infections. during 8 month study, 73 clinically p. aeruginosa isolates collected from patients hospitalized in burn ward...

Photodynamic antimicrobial chemotherapy (PACT), as a novel and effective therapeutic modality to eradicate drug resistant bacteria without provoking multidrug resistance, has attracted increasing attention. This study examined the antimicrobial efficacy of the novel cationic amino acid-porphyrin conjugate 4I with four lysine groups against two different clinical isolated strains (drug sensitive...

background: this study was done to detect multidrug resistant (mdr) and extremely drug resistant (xdr) of pseudomonas aeruginosa among strains isolated from patients in tehran, iran, due to importance of these phenotypes in treatment of human infections. methods: eighty eightp. aeruginosa were isolated from patients in tehran, iran, and identified by routine methods and pcr for oprl gene. their...

The prevalence of antimicrobial resistance in 128 Escherichia coli isolates was investigated in two species of invasive alien mammals (IAMs): the small Asian mongoose (SAM) and Japanese weasel (JW). The SAM is found on the main island of Okinawa, Japan, where a large number of livestock is available, and the JW is present on a small island, where is isolated from the main island, and have a sma...

BACKGROUND Several studies have reported higher rates of antimicrobial resistance among isolates from intensive care units than among isolates from general patient-care areas. The aims of this study were to review the pathogens associated with nosocomial infections in a surgical intensive care unit of a university hospital in Turkey and to summarize rates of antimicrobial resistance in the most...

Cladophora and Enteromorpha are the filamentous green-algal genuses that have a widespread distribution in Caspian Sea Coast. The aim of this study was to assess the antimicrobial activities of Cladophora and Enteromorpha in South of Caspian Sea. Antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including Staphylococcus aureus, Bacillus su...
