Massive global spread of multidrug-resistant (MDR) Salmonella spp. expressing extended-spectrum beta-lactamase (ESBL) and additional resistance to fluoroquinolones has often been attributed to high international mobility as well as excessive use of oral antibiotics in livestock farming. However, MDR Salmonella spp. have not been mentioned as a widespread pathogen in clinical settings so far. We...
Resistance to chemotherapeutic agents is a major obstacle in cancer treatment. A recently proposed strategy target the collateral sensitivity of multidrug resistant (MDR) cancer. Paradoxically, toxicity certain metal chelating increased, rather than decreased, by function P-glycoprotein (Pgp), which known confer resistance effluxing compounds from cells. We have characterized and compared solut...
Background: Atypical enteropathogenic Escherichia coli (aEPEC) is regarded as a globally emerging enteropathogen. aEPECs exhibit various level of resistance to a range of antibiotics, which is increasing alarmingly. The present study investigated the antimicrobial resistance of aEPEC isolates recovered from diarrheal patients, healthy carriers, animals, and raw meats. Results: Among 267 aEPEC i...
Antimicrobial resistance to nine anti-pseudomonal agents (azteronam, ceftazidime, cefepime, piperacillin/tazobactam, imipenem, meropenem, ciprofloxacin, amikacin and gentamicin), the magnitude of multidrug resistance, associated underlying conditions, and mortality among patients with Pseudomonas aeruginosa isolates from King Khalid University Hospital, Riyadh, Saudi Arabia from 2001 to 2005 we...
BACKGROUND Overexpression of ATP-binding cassette (ABC) transporters such as P-glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1) or breast cancer resistance protein (BCRP) accounts for majority of cases of multidrug resistance (MDR) of cancer cells. MATERIALS AND METHODS In the present work, the interactions of seven commercially available phenothiazine derivatives, known ...
Drug-resistant Mycobacterium tuberculosis is challenging elimination of tuberculosis (TB). We evaluated risk factors for TB and levels of second-line drug resistance in M. tuberculosis in patients in Europe with multidrug-resistant (MDR) TB. A total of 380 patients with MDR TB and 376 patients with non-MDR TB were enrolled at 23 centers in 16 countries in Europe during 2010-2011. A total of 52....
A survey of the expression of the multidrug-resistance gene (mdr) in mouse tissues revealed that a mdr mRNA species is expressed at extremely high levels in the gravid uterus. mdr mRNA expression levels increase dramatically during pregnancy compared to the relatively low levels of expression observed in the nongravid uterus. In situ hybridization experiments revealed that the increased express...
OC144-093 is a novel substituted diarylimidazole (Mr 495) generated using the OntoBLOCK system, a solid-phase combinatorial chemistry technology, in combination with high-throughput cell-based screening. OC144-093 reversed multidrug resistance (MDR) to doxorubicin, paclitaxel, and vinblastine in human lymphoma, breast, ovarian, uterine, and colorectal carcinoma cell lines expressing P-glycoprot...
Trends of rising rates of resistance in Pseudomonas aeruginosa make selection of appropriate empirical therapy increasingly difficult, but whether multidrug-resistant (MDR) P. aeruginosa is associated with worse clinical outcomes is not well established. The objective of this study was to determine the impact of MDR (resistance to three or more classes of antipseudomonal agents) P. aeruginosa b...
Multidrug-resistant (MDR) Gram-negative infections represent a growing problem and a serious global threat. Carbapenem-resistant Klebsiella pneumoniae is perhaps cause the most difficult infection to treat and is associated with increased morbidity and mortality. Here, we report the draft genome sequence of an MDR K. pneumoniae strain isolated from Makkah, Saudi Arabia.
