The incidence of extended-spectrum beta-lactamases (ESBLs) was analyzed in Enterobacteriaceae population circulating in the Upper Silesian Child and Mother Health Center in Katowice (USC&MHC). Altogether 1164 clinical specimens, collected from children hospitalized in 8 different hospital units of USC&MHC were investigated. Five hundred and eighty-five clinical isolates of the family Enterobact...
Background. Enterobacteriaceae play an important role in the pathogenesis of hospital infections worldwide. The Tigecycline Evaluation Surveillance Trial (TEST) examines the susceptibility of pathogens isolated from multiple infectious processes from patients in geographically diverse populations. With the increase of antimicrobial resistance, continued surveillance and susceptibility testing o...
Increasing resistance to third generation cephalosporins has become a cause for concern especially among Enterobacteriaceae that cause nosocomial infections. The prevalence of extended spectrum beta-lactamases (ESBLs) among members of Enterobacteriaceae constitutes a serious threat to current beta-lactam therapy leading to treatment failure and consequent escalation of costs. A detailed study w...
During the last decade, Gram-negative clinical isolates, including Enterobacteriaceae, Pseudomonas spp. and Acinetobacter spp. with decreased susceptibility to carbapenems, have been increasingly reported in Europe. Carbapenem resistance in Enterobacteriaceae may be related either to the association of a decrease in bacterial outer-membrane permeability with overexpression of b-lactamases posse...
This study compared the in vitro activities of ertapenem, ceftriaxone, co-amoxiclav, ciprofloxacin and piperacillin-tazobactam against 314 aerobic bacteria and of ertapenem, piperacillin-tazobactam, cefoxitin, ceftriaxone, chloramphenicol, ticarcillin-clavulanate, ampicillin-sulbactam, clindamycin and metronidazole against 500 anaerobic bacteria from 212 patients with acute pelvic infection. An...
Limited data identify the risk factors for infection with Enterobacteriaceae resistant to third-generation cephalosporins among residents of long-term-care facilities. Using a nested case-control study design, nursing home residents with clinical isolates of Enterobacteriaceae resistant to third-generation cephalosporins were compared to residents with isolates of Enterobacteriaceae susceptible...
High quinolone resistance rates were observed among oxyiminocephalosporin-resistant enterobacteria. In the present study, we searched for the prevalence of plasmid-mediated quinolone resistance (PMQR) genes within the 55 oxyiminocephalosporin-resistant enterobacteria collected in a previous survey. The main PMQR determinants were aac(6')-Ib-cr and qnrB, which had prevalence rates of 42.4% and 3...
Objective To investigate the risk factors underlying the occurrence and mortality of bloodstream infections (BSIs) with carbapenem-resistant Enterobacteriaceae (CRE). Methods Medical information was retrospectively analyzed from 148 cases of patients with Enterobacteriaceae BSIs at a medical center in China, between 2013 and 2015. Results The 30-day mortality rate in the CRE group was 65.4%...
Enterotube, a multiple-test system which combines nine biochemical tests useful in the identification of members of the family Enterobacteriaceae, was tested and compared with the PathoTec test system in the identification of gram-negative bacilli isolated from clinical specimens. It was found that both the Enterotube and the PathoTec systems rapidly and accurately defined the position of the o...
β-lactamases are the primary cause of resistance to β-lactams among members of the family Enterobacteriaceae. SHV enzymes have emerged in Enterobacteriaceae causing infections in health care in the last decades of the Twentieth century, and they are now observed in isolates in different epidemiological settings both in human, animal and the environment. Likely originated from a chromosomal peni...
