The emergent bacterial resistance to antibiotics, most especially Carbapenems, has become a common phenomenon. aim of the recent study was observation and evaluation antibacterial susceptibility Klebsiella pneumoniae in clinical specimens different Carbapenems. One hundred isolates K. isolated from sites, such as leg, caesarean section (CS), head, buttock, breast, thigh, arm were tested. Using ...

background pseudomonas aeruginosais an opportunistic pathogen which causes severe, acute and chronic nosocomial infections. these infections are difficult to eradicate since the organisms are usually multidrug-resistant. carbapenems are considered as the most effective drugs against these isolates. however, recent emergence of carbapenem-resistant p. aeruginosa has become a major healthcare pro...

beta-lactams are a group of antibiotics with a broad spectrum of both gram-negative and gram-positive coverage. the goal of this study is to evaluate the results from studies regarding ig-e mediated hypersensitivity to penicillin and cross-reactivity with other beta-lactams. review was conducted of both retrospective and prospective studies by searching in pubmed and medline for the original an...

Studies performed on subjects with IgE-mediated hypersensitivity to penicillins have demonstrated a 1% rate of cross-reactivity between penicillins and both imipenem and meropenem, while a single study found a 5.5% rate of cross-reactivity with imipenem/cilastatin in subjects with T-cell-mediated hypersensitivity to β-lactams, mostly penicillins. We studied 204 consecutive subjects with a well-...

antimicrobial activity of carbapenems, the postantibiotic effect (PAE) is a prominent feature. Carbapenems have been shown to produce PAEsnot only against Grampositive bacteria but also against Gram-negative bacteria by several investigators1 ~ 5). The aim of the present study was to simultaneously compare the PAE of newer carbapenems (such as meropenemand biapenem) with that of imipenemagainst...

OBJECTIVES The purpose of this retrospective study was to ascertain the clinical safety of administering carbapenems, namely imipenem/cilastatin and meropenem, in patients with a history of penicillin allergy compared with administering carbapenems in patients with no reported penicillin allergy. Carbapenems are similar in chemical structure to the penicillins and therefore are associated with ...

The Ministry of Health and Welfare, Japan banned coadministration of carbapenems, such as panipenem/betamipron (PAPM), meropenem (MEPM), and valproic acid (VPA) because clinical reports have indicated that the coadministration caused seizures in epileptic patients due to lowered plasma levels of VPA. In this study, we have clarified the mechanism of the drug-drug interaction using PAPM, MEPM, a...

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...
