The spread of carbapenem resistant Enterobacteriaceae (CRE) has recently become a matter of concern in public health, mainly due to the wide distribution of carbapenemase genes. Italy is a country considered endemic for the spread of blaKPC Klebsiella pneumoniae (KP). The aim of this study was to depict the epidemiological trend of CRE in one Italian hospital over a long period (3 years surveil...

CL 188,624, CL 190,294, and CL 191,121 are novel aminomethyl tetrahydrofuranyl (THF)-1 beta-methylcarbapenems. The in vitro antibacterial activities of these THF carbapenems were evaluated and compared with those of biapenem, imipenem, and meropenem against 554 recent clinical isolates obtained from geographically distinct medical centers across North America. The antibacterial activities of th...

We examined the effect of the addition of ertapenem to our hospital formulary on the resistance of nosocomial Pseudomonas aeruginosa to group 2 carbapenems (imipenem, meropenem, and doripenem). This was a retrospective, observational study conducted between 1 January 2000 and 31 January 2009 at a large, tertiary-care hospital. Autoregressive integrated moving average (ARIMA) regression models w...

Enterobacter massiliensis strain JC163(T) sp. nov. is the type strain of E. massiliensis sp. nov., a new species within the genus Enterobacter. This strain, whose genome is described here, was isolated from the fecal flora of a healthy Senegalese patient. E. massiliensis is an aerobic rod. Here we describe the features of this organism, together with the complete genome sequence and annotation....

Coliform tests were performed on 85 hide and 75 meat samples. IMViC reactions were determined on isolates from positive confirmed and fecal tests, and strains other than Escherichia coli were identified. Strains typed as Aerobacter aerogenes types I and II were identified as Enterobacter cloacae (51.4%), Klebsiella pneumoniae (21.5%), Enterobacter aerogenes (15%), and Enterobacter liquefaciens,...

Carbapenem-resistant Enterobacteriaceae (CRE) has increasingly spread worldwide in the past decade. The prevalence and characteristics of CRE in Thailand are unknown. In this study, we conducted a 2-year surveillance of CRE among 12,741 clinical isolates of Enterobacteriaceae at the largest university hospital in Thailand with molecular characterization of beta-lactamase (bla) genes, including ...

BACKGROUND Extended-spectrum β-lactamases (ESBLs) are increasingly prevalent in Enterobacter spp., posing a challenge to the treatment of infections caused by this microorganism. The purpose of this retrospective study was to evaluate the prevalence, risk factors, and clinical outcomes of inpatients with bacteremia caused by ESBL and non ESBL-producing Enterobacter spp. in a tertiary hospital o...

BACKGROUND Emergence of carbapenems-resistant K. pneumoniae represents a serious challenge for antimicrobial therapy. OBJECTIVE The aim of this research is to determine different mechanisms mediating the emergence of K. pneumoniae isolates with high-level carbapenem resistance. METHOD A total of 80 K. pneumoniae isolates were purified from sputum and urine specimens. The minimum inhibitory ...

in recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. the presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. the coal mine area in bokaro is one of the “toxic hotspot” in india. bacteria have evolved uptake and efflux mec...
