Exposure and sensitization to cockroach allergens is an important risk factor for allergic disease in humans. Despite a recent burgeoning of clinical and socioeconomic studies regarding environmental pervasiveness and human exposure to cockroach allergens, little is known about the basic biology of these proteins. The purpose of this study was to ascertain gene expression patterns and the tissu...
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) is a concern in South Africa and worldwide. It is therefore important that these organisms be accurately identified for infection prevention control purposes. METHOD In this study 1193 suspected CREs from 46 laboratories from seven provinces in South Africa were assessed to confirm the prevalence of carbapenemase genes from our referral...
CTX-M-producing Escherichia coli isolates from three Croatian hospitals were analyzed. All bla(CTX-M-15) genes and one bla(CTX-M-3a) gene resided in widely spread ISEcp1 transposition modules, but other bla(CTX-M-3a) genes were in a new configuration with two IS26 copies, indicating a new event of gene mobilization from a Kluyvera ascorbata genome. The study confirmed the role of the E. coli ST...
Carbapenem resistance in Acinetobacter spp. is an emerging problem in China. We investigated the molecular epidemiology and carbapenemase genes of 221 nonrepetitive imipenem-resistant clinical isolates of Acinetobacter spp. collected from 1999 to 2005 at 11 teaching hospitals in China. Genotyping by pulsed-field gel electrophoresis (PFGE) found 15 PFGE patterns. Of these, one (clone P) was iden...
During a regular monitoring of antimicrobial resistance in a farrowing farm in Southern China, 117 Escherichia coli isolates were obtained from sows and piglets. Compared with the isolates from piglets, the isolates from sows exhibited higher resistance rates to the tested cephalosporins. Correspondingly, the total detection rate of the bla CMY-2/bla CTX-M genes in the sow isolates (34.2%) was ...
Individual cloacal swabs of mallards (Anas platyrhynchos) and of herring gulls (Larus argentatus), as well as samples of waterbird feces obtained in 2008 and 2009, were cultivated for Escherichia coli. Isolates of E. coli were tested for susceptibilities to 12 antimicrobial agents by the disk diffusion method. Moreover, the samples were subcultivated on MacConkey agar (MCA) containing cefotaxim...
Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae have emerged as major nosocomial pathogens. bla(KPC), commonly located on Tn4401, is found in Gram-negative bacterial strains, with the two most common variants, bla(KPC-2) and bla(KPC-3), identified in plasmids with diverse genetic backgrounds. In this study, we examined bla(KPC-4)- and bla(KPC-5)-bearing plasmids recovered...
there is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. the present research investigated the possible involvement of lateralization of basolateral amygdala (bla) and central amygdala (cea) in place avoidance memory. for this purpose, male long-evans rats (280-320 g) were im...
conclusions our findings showed a high occurrence of metallo-β-lactamase production among p. aeruginosa isolates in burn patient infections in our region. also, there are p. aeruginosa isolates carrying the bla-vim-1 and bla-vim-2 genes in isfahan province. background metallo-β-lactamase-production among gram-negative bacteria, including pseudomonas aeruginosa, has become a challenge for treatm...
Some studies have shown that acetylcholine muscarinic receptors involved in the opiate reward. In the present study, the effect of intra-basolateral amygdale (BLA) acetylcholine muscarinic like receptor agonist (physostigmine) and antagonist (atropine) on the acquisition of morphine-induced place preference has been investigated in male Wistar rats. For this purpose, two 22 gauges guide cannula...
