conclusions it was the first report on the blactx-m-15 gene emergence in clinical enterobacter spp. in iran. the current study demonstrated the predominant presence of the gene encoding ctx-m-15 among esbl producing enterobacter spp. commonly with a large plasmid, in the setting. background enterobacter spp. is increasingly recognized as an important nosocomial pathogen and implicated in many e...
to study the resistance to standard dosage of clopidogrel among iranian patients following percutaneous coronary intervention measured by platelet aggregation test.patients undergoing percutaneous coronary intervention in imam hussein medical center, tehran, iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. patients received standard dosage...
emerging new medications in the treatment of hbv produces hope and promises for curing of hbv. over the past decade, the development of oral nucleoside/nucleotide analogs (nas) with favorable potencies and tolerabilities has led to substantial advances in chronic hepatitis b (chb) therapy. the oral anti-hbv agents currently approved are lamivudine, adefovir dipivoxil , entecavir , telbivudine, ...
background and objective: implementation of standard methods for accurate detection of bacteria, correct antibiotic susceptibility testing and effective treatment of bacterial infections play important roles in development of public health and prevention of drug resistance. this study aimed to detect bacteria using standard methods and compare the results with the results obtained in teaching h...
OBJECTIVE To evaluate the rates of penicillin, clindamycin and erythromycin resistance and the serotype distribution among isolates of group B streptococcus (GBS) obtained from pregnant women at the University Hospital of Bern in Switzerland. METHODS We prospectively collected screening samples for GBS colonisation at the University Women's Hospital Bern, Switzerland, between March 2009 and A...
Plasmids of incompatibility group (Inc) HI1 are important vectors of antibiotic resistance in both of the major causal agents of enteric fever: Salmonella enterica subspecies enterica serovar Typhi and S. Paratyphi A. In S. Typhi, IncHI1 plasmids appeared in the 1970s and spread globally. In some circumstances they are maintained within the bacterial population even in the absence of selection ...
Group B streptococci (GBS) comprising three different sets of isolates (31 invasive, 36 noninvasive, and 24 colonizing isolates) were collected in Italy during the years 2002 to 2005. Clonal groups were established by pulsed-field gel electrophoresis (PFGE), and selected isolates were studied by multilocus sequence typing (MLST). GBS isolates were also characterized by classical and molecular t...
Due to frequent antibiotic exposure, swine is now recognized as potential risk in disseminating drug-resistant Salmonella enterica strains. This study thus subjected 20 randomly selected S. enterica isolates from tonsil and jejunum with lymph node (JLN) tissues of swine slaughtered in Metro Manila, Philippines, to VITEK 2 antimicrobial susceptibility testing (AST). The test revealed all 20 isol...
BACKGROUND Introduction of the 7-valent pneumococcal conjugate vaccine (PCV7) in the United States in 2000 was temporally associated with an increase in the incidence of disease caused by Streptococcus pneumoniae serotype 19A (Sp19A) and with increasing drug resistance within this serotype. A causative role of PCV7 was speculated. We prospectively studied the dynamics of acute otitis media (AOM...
BACKGROUND The emergence of resistance to antimicrobial agents within the salmonellae is a worldwide problem that has been associated with the use of antibiotics in livestock. Resistance to ceftriaxone and the fluoroquinolones, which are used to treat invasive salmonella infections, is rare in the United States. We analyzed the molecular characteristics of a ceftriaxone-resistant strain of Salm...
