BACKGROUND Klebsiella pneumoniae carbapenemase (KPC) is one of the carbapenemases that can cause multi-antibiotics resistance in Acinetobacter baumannii. A simple phenotypic rapid and accurate test for the detection of A. baumannii - KPC-producer can be useful in treating related infections. The aim of this study was to determine the synergism effect of boronic acid (BA), as an inhibitor, and m...

A 28-year-old woman presented with an erythematous rash involving the nose, nasolabial folds, and philtrum that appeared after she had manipulated a painful vesicular lesion at the base of her nose that she believed to be a pimple. The patient received cloxacillin for presumed erysipelas and had a partial response. However, after cloxacillin therapy, worsening induration (Panel A) prompted trea...

Six Klebsiella pneumoniae isolates that exhibited resistance to a wide spectrum of antibiotics were recovered from the intensive care units in the First Affiliated Hospital, Zhejiang University, Hangzhou, China. All isolates contained two plasmids of approximately 95 kb and 200 kb. The 95 kb plasmid was shown to be transferable by conjugation experiments. Isoelectric focusing patterns of the be...

curves of precipitation are shown in Figure 1. Ampicillin, carbenicillin, amoxycillin, procaine penicillin, cephalothin, salicylic acid, acetylsalicylic acid, and dexamethasone caused no interference. The presence of methicillin in urine may be differentiated from the turbidity attributable to protein by measuring the absorbance at different intervals during the reaction, such as 0.5 and 5.0 mm...

The incidence of resistance by Enterobacteriaceae to β-lactam/β-lactamase inhibitors combination is increasing in Egypt. Three phenotypic techniques, comprising AmpC disk diffusion and inhibition dependent methods using phenylboronic acid (PBA) and cloxacillin, were compared to PCR based method for detection of plasmid mediated AmpC β-lactamase in common urinary tract isolates. A total of 143 i...

We report the first case of supernumerary puncta and canaliculi presented with canaliculitis. A-59 year-old gentleman presented with painful swelling of the left lower lid for a week, which was associated with epiphora. The swelling was confined to the nasal aspect of the left lower lid (0.5×0.5 mm) with inflamed overlying skin. Two puncta (0.5 mm apart) were noted. The outer punctum at the nor...

The aerobic microbial flora of 823 eyes with acute bacterial conjunctivitis, corneal ulceration, dacryocystitis, discharging sockets, blepharitis, and postoperative infections has been investigated. Staphylococci, Streptococcus pneumoniae, and nonfermenting Gram-negative bacilli including Pseudomonas aeruginosa were the main pathogens. Fermenting coliforms were also infrequently isolated. The l...

Two chromosome-encoded beta-lactamases have been purified from Citrobacter diversus ULA-27. They exhibited slightly different isoelectric points (6.8 and 6.2) and very similar Mr values (congruent to 29,000). Their specificity spectrum was rather wide, since they hydrolysed some cephalosporins with kcat: values similar to those observed with the best penicillin substrates. Cloxacillin, methicil...
