conclusions our study showed that the prevalence of esbl-producing k. pneumoniae at king khalid hospital was significantly high. routine detection of esbl-producing microorganisms is required by each of the laboratory standard detection methods to control the spread of these infections and allow a proper therapeutic strategy. for detection, the phenotypic confirmatory disc diffusion test is sim...

Earlier studies showed that phenobarbital feeding enhanced hepatic tumorigenesis in rats previously fed 2-acetylaminofluorene for a brief period. As part of an investigation of the mechanism of this enhancement, the present study evaluated the relative enhancing abilities of amobarbital, diphenylhydantoin, and dichlorodiphenyltrichloroethane (DDT), agents that resemble phenobarbital to varying ...

The study aimed to evaluate the susceptibility of Anopheles species to DDT 4% and deltamethrin 0.05%. Mosquitoes were tested for their susceptibility to both insecticides following WHO standards and using test kit provided by WHO. The study indicated that Anopheles mosquito was found tolerant to DDT 4% and deltamethrin 0.05% in Juba County in all mosquitoes collected from the sentinel sites. Ho...

objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...

Dorsal root ganglion neurones with dichotomising axons are present in several species and are considered to play a role in referred pain. Clinically, patients with lesions in the lower lumbar discs occasionally complain of pain in the groin. We investigated the existence of dichotomising afferent neurones projecting axons both to the lumbar disc and to the groin skin, using the double fluoresce...

One DDT-contaminated soil and two uncontaminated soils were used to enumerate DDT-resistant microbes (bacteria, actinomycetes and fungi) by using soil dilution agar plates in media either with 150 mg DDT ml−1 or without DDT at different temperatures (25, 37 and 55◦C). Microbial populations in this study were significantly (p<0.001) affected by DDT in the growth medium. However, the numbers of m...

BACKGROUND The debate regarding dichlorodiphenyltrichloroethane (DDT) in malaria prevention and human health is polarized and can be classified into three positions: anti-DDT, centrist-DDT, pro-DDT. OBJECTIVE We attempted to arrive at a synthesis by matching a series of questions on the use of DDT for indoor residual spraying (IRS) with literature and insights, and to identify options and opp...

In 1994 and 1995, nesting success of double-crested cormorants (Phalacrocorax auritus) was measured at Cat Island, in southern Green Bay, Lake Michigan, Wisconsin, USA. Sample eggs at pipping and unhatched eggs were collected and analyzed for organochlorines (including total polychlorinated biphenyls [PCBs] and DDE), hepatic microsomal ethoxyresorufin-O-dealkylase (EROD) activity in embryos, an...

background: resistance to contemporary broad-spectrum b-lactam antibiotics mediated by extended-spectrum b-lactamases (esbls) is increasing worldwide. klebsiella pneumoniae , an important cause of nosocomial and community acquired urinary tract infections has rapidly become the most common esbl producing organism. we examined esbl production in urinary isolates of k. pneumoniae in relation to t...
