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...

Knowledge of side effects associated with different cephalosporins may be of help to prescribers. There are several side effects that are common to all cephalosporins, but overall, cefotaxime and ceftizoxime cause the fewest adverse reactions. Bleeding is probably the most common serious side effect of cephalosporins. Moxalactam causes coagulopathy and bleeding more often than do other cephalos...

INTRODUCTION An analysis was made about the evolution of resistance to 3rd generation cephalosporins, imipenem, and other antibiotics in invasive isolates of Klebsiella pneumoniae (K. pneumoniae) according to the Spanish EARS-Net database (2010-2014). METHODS Forty-two hospitals from 16 Autonomous Communities with an approximate population coverage of 33% participated. RESULTS A total 7,140...

In this study, the effects of antimicrobial agents on 105 P.aeruginosa strains isolated from various clinical specimens were examined. The frequency as follows; pus (29), urine (28); thorat (17) and ear (13) swabs, feces (10) phlegm (8). Antibiotic susceptibility test was done through Kirby-Bauer Disc Diffusion Method. to 3rd generation cephalosporins, quinolones, carbapenems aminoglycosides fo...

Extended-spectrum-β-lactamases (ESBLs), constitutes the growing class of betalactamses, these are enzymes produced by bacteria which impart resistance against advanced-generation-cephalosporins. SHV enzymes are among the most prevalent ESBLs. The mode of molecular interactions of recent SHV-variants to advanced generation cephalosporins has not been reported yet. This is the first time we are r...

Most drug-induced immune hemolytic anemias since the late 1980s have been caused by the secondand third-generation cephalosporins, cefotetan and ceftriaxone, respectively. Cross-reactivity of cefotetan and ceftriaxone antibodies with other cephalosporins or penicillin has been studied only minimally. We tested 7 serum samples previously identified to contain cefotetan antibodies and one serum s...

Enterobacter cloacae resistant to third generation cephalosporins emerged rapidly during an outbreak of serious infections due to this organism in a neonatal intensive care unit where ampicillin and gentamicin were used as first line antibiotic treatment. Organisms resistant to cephalosporins were isolated from 12 infants, six of whom developed systemic infection. Two infants died. Isolates of ...

The validity of the class representative concept for in vitro susceptibility testing of older cephalosporins was reevaluated. Two oral cephalosporins, cephalexin and cefaclor, were compared with the established cephalosporin class representative, cephalothin, by using reference microdilution minimal inhibitory concentrations of 528 isolates of a wide variety of gram-positive and gram-negative b...

Among 477 patients with susceptible Enterobacter spp., 49 subsequently harbored third-generation cephalosporin-resistant Enterobacter spp. Broad-spectrum cephalosporins were independent risk factors for resistance (relative risk [OR] = 2.3, P = 0.01); quinolone therapy was protective (OR = 0.4, P = 0.03). There were trends toward decreased risk for resistance among patients receiving broad-spec...
