Coban, AY; Cihan, CC; Bilgin, K; Uzun, M; Akgunes, A; Cetinkaya, E; Durupinar, B (Int Union Against Tuberculosis Lung Disease (I U A T L D), 2006)OBJECTIVE: To evaluate the performance of blood agar for the susceptibility testing of 50 Mycobacterium tuberculosis clinical isolates against isoniazid (INH), rifampicin (RMP), streptomycin (SM) and ethambutol (EMB). ... -
A comparison of the E-test and proportion methods for susceptibility testing of Mycobacterium tuberculosis
Sanic, A; Gunaydin, M; Coban, AY; Tokac, MS; Cetin, M (Taylor & Francis Ltd, 2000)The aim of this study was to investigate the correlation between three antibiotic susceptibility methods, the proportion method on Lowenstein Jensen medium (LJ medium), the proportion method on Middlebrook 7H11 agar (7H11 ... -
Comparison of the proportion method with mycobacteria growth indicator tube and E-test for susceptibility testing of Mycobacterium tuberculosis
Birinci, A; Coban, AY; Ekinci, B; Durupinar, B (Fundaco Oswaldo Cruz, 2002)The aim of this study was to investigate the correlation between proportion method with mycobacteria growth indicator tube (MGIT) and E-test for Mycobacterium. tuberculosis. Foro, clinical isolates were tested. MGIT and ... -
Drug susceptibility testing of Mycobacterium tuberculosis by the broth microdilution method with 7H9 broth
Coban, AY; Birinci, A; Ekinci, B; Durupinar, B (Fundaco Oswaldo Cruz, 2004)In this study, we have evaluated the broth microdilution method (BMM) for susceptibility testing of Mycobacterium tuberculosis. A total of 43 clinical isolates of M. tuberculosis and H37Rv as a control strain were studied. ... -
Drug susceptibility testing of Mycobacterium tuberculosis with nitrate reductase assay
Coban, AY; Birinci, A; Ekinci, B; Durupinar, B (Elsevier Science Bv, 2004)The nitrate reductase assay (NRA) was evaluated for susceptibility testing of Mycobacterium tuberculosis using 80 clinical isolates of M. tuberculosis and H37Rv as a control strain. All isolates were tested by the proportion ... -
The effect of nitric oxide combined with fluoroquinolones against Salmonella enterica serovar Typhimurium in vitro
Coban, AY; Durupinar, B (Fundaco Oswaldo Cruz, 2003)Two regulons, soxRS and marRAB, are associated with resistance to quinolones or multiple antibiotic in Salmonella enterica serovar Typhimurium. These regulons are activated by nitric oxide and redox-cycling drugs, such as ... -
Effects of acetyl salicylate and ibuprofen on fluoroquinolone MICs on Salmonella enterica serovar typhimurium in vitro
Coban, AY; Birinci, A; Ekinci, B; Durupinar, B (Taylor & Francis Ltd, 2004)In this study, the effects of acetylsalicylate and ibuprofen at 2, 4 and 8 mM concentration were investigated on ofloxacin, ciprofloxacin, levofloxacin and pefloxacin minimum inhibitory concentrations (MICs) for 14 Salmonella ... -
HLA alleles and lung cancer in a Turkish population
Ozbek, N; Birinci, A; Karaoglanoglu, O; Coban, AY; Okumus, B; Cakir, S; Durupinar, B (K Faisal Spec Hosp Res Centre, 2004)Background: The concept of genetic factors playing a role in the pathogenesis of lung cancer has gained increased attention. The present,study was undertaken to examine the question of HLA association with lung cancer and ... -
In vitro effects of cefotaxime and ceftriaxone on Salmonella typhi within human monocyte-derived macrophages
Ekinci, B; Coban, AY; Birinci, A; Durupinar, B; Erturk, M (Blackwell Publishing Ltd, 2002)The main objective of this in vitro study was to assess the effects of cefotaxime and ceftriaxone in killing Salmonella typhi in infected human macrophages. Human monocyte-derived macrophages isolated from peripheral blood ... -
A multidrug efflux pump inhibitor reduces fluoroquinolone resistance in Pseudomonas aeruginosa isolates
Coban, AY; Ekinci, B; Durupinar, B (Karger, 2004)In general, resistance to fluoroquinolones (FQs) in gram-negative bacteria is acquired either by mutations in DNA gyrase and topoisomerase IV or by active export of the agents via antibiotic efflux pumps. Reduced porin ... -
The resazurin microplate method for rapid detection of vancomycin resistance in enterococci
Coban, AY; Darka, O; Fisgin, NT; Cihan, CC; Bilgin, K; Akgunes, A; Durupinar, B (Taylor & Francis Ltd, 2005)Vancomycin-resistant enterococci (VRE) are a serious challenge for physicians because of the limited treatment options for infections caused by this organism. Prevention of VRE transmission in hospitals requires early ... -
Susceptibilities of Mycobacterium tuberculosis to isoniazid and rifampin on blood agar
Coban, AY; Bilgin, K; Uzun, M; Fisgin, NT; Akgunes, A; Cihan, CC; Durupinar, B (Amer Soc Microbiology, 2005)In this study, blood agar was used instead of 7H10 agar for the susceptibility testing of 34 clinical isolates of Mycobacterium tuberculosis to isoniazid (INH) and rifampin (RIF) in accordance with the NCCLS. The BACTEC ... -
Two new colorimetric methods for early detection of vancomycin and oxacillin resistance in Staphylococcus aureus
Coban, AY; Bozdogan, B; Cihan, CC; Cetinkaya, E; Bilgin, K; Darka, O; Appelbaum, PC (Amer Soc Microbiology, 2006)We developed two colorimetric methods for the detection of vancomycin- and oxacillin-resistant Staphylococcus aureus in <= 6 h: (i) a nitrate reductase assay and (ii) a resazurin microplate method. MICs agreed with results ...
