OBJECTIVES: Pentavalent antimonials have been used for the treatment of leishmaniasis for more than 70 years; however their toxicity limits their benefits. Unfortunately, the efficacy of the first line drugs has been decreased and resistance seems to be noticeable. Luliconazole is a new azole with unique effects on fungi which has not been tested on Leishmania parasites yet. METHODS: In the present study, we evaluated cytotoxicity and anti-leishmanial activities of Luliconazole on promastigotes and intracellular amastigotes of Leishmania major (L...

INTRODUCTION: Although Corynebacterium species are part of the skin and mucous membranes microbiota, human infections caused by Corynebacterium spp. have been reported and the multidrug resistance pattern of the recovered isolates was emphasized. Due to the usefulness of disk diffusion in daily practice, the purpose of this work was to compare disk diffusion against agar dilution to determine disk diffusion breakpoints and to review the antimicrobial susceptibility of the most frequent Corynebacterium spp...

OBJECTIVES: Carbapenemase-producing Escherichia coli are of major clinical concern. The present study aimed to identify NDM-5 producing E.coli associated with community-acquired urinary tract infection, co-harboring ESBL genes and a pattern of imipenem MIC creep. METHODS: A total of 973 urine samples were collected from females of age between 18-49 diagnosed with UTI. Isolates were identified by standard microbiological procedures. Presence of blaNDM and ESBL genes was determined by PCR assay and sequencing...

OBJECTIVE: Glycopeptides are being increasingly used to multi-resistant MRSA infections. We report MRSA with low level teicoplanin resistance recovered from a patient treated with teicoplanin for fatal necrotizing fasciitis. PATIENT AND METHODS: MRSA recovered from a patient with necrotizing fasciitis was treated with teicoplanin. The minimum inhibitory concentration (MIC) for vancomycin and teicoplanin was determined using E-test. Reduced glycopeptide susceptibility was screened using GRD E-test and population analysis profile (PAP) method...

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is a threat to clinical treatment. Besides high resistance, presence of heterogeneous vancomycin intermediate S. aureus (hVISA) and heterogeneous daptomycin non-susceptible S. aureus (hDNSSA) in the hospital environment are underestimated and associated with treatment failure. OBJECTIVES: To investigate a MRSA dissemination in a Brazilian hospital and to evaluate the efficacy of some treatment options in vitro...

OBJECTIVES: This study assessed trends and patterns in antimicrobial resistant intensive care unit (ICU)-acquired infections caused by Gram-negative bacteria (GNB) in Istanbul, Turkey. METHODS: Bacterial culture and antibiotic susceptibility data were collected for all GNB causing nosocomial infections in five adult ICUs of a large university hospital during 2012-2015. Multi-resistance patterns were categorised as multidrug (MDR), extensively-drug (XDR) and pandrug (PDR)-resistance...

BACKGROUND: Fluoroquinolones (FQs) are recommended as the drug of choice for the empirical treatment of urinary tract infections (UTIs).We aimed to investigate the molecular determinants of FQ resistance in Escherichia coli and Klebsiella pneumoniae isolates. METHODS: A total of 364 clinical isolates of E. coli (n=144) and K. pneumoniae (n=220) were collected from patients with UTI. Susceptibility of the isolates to ciprofloxacin, levofloxacin, gatifloxacin and nalidixic acid was evaluated by using disc diffusion method...

OBJECTIVES: Although blaNDM-1 has now been widely detected in various Enterobacteriaceae clinical isolates, multiple blaNDM-1 colonizations within the same patient remain rare. The aim of the study was to describe a patient with respiratory tract colonization of NDM-1-producing Escherichia coli and Citrobacter freundii during a hospitalization in China. METHODS: Two carbapenem-resistant isolates were analysed. Susceptibility testing, metallo-β-lactamase production, conjugation, plasmid analysis, and molecular typing were performed...

OBJECTIVES: Candida albicans is a commensal pathogen associated with both superficial (mucosal and cutaneous) and systemic infections. The extensive use of antifungal agents has led to reduced susceptibility to the few existing drugs. This situation has encouraged the search for novel antifungal agents. Therefore, in the present study, we investigated the antifungal activity of 2,6-bis[(E)-(4-pyridyl)methylidene]cyclohexanone (PMC). METHODS: We evaluated its in vitro activity against C...

OBJECTIVES: The effectiveness of disinfectants can vary according to the microorganism, type of residues and surface. Hence, the aim of this study was to determine the effectiveness of four disinfectants in the presence of organic matter and their residual effect on stainless steel grade 304 (SS) and polypropylene B (PP-B). METHODS: The disinfectant effectiveness in the presence of meat extract, yolk egg and whole milk was determined according to AOAC and UNE-EN 1040:2015; the residual effect was realized according to UNE-EN 13697:2015, using approved strains...

OBJECTIVES: Brucellosis, is among one of the most widespread important global zoonotic diseases which is endemic in many parts of India. Brucella melitensis is supposed to be the most pathogenic species for humans. Here, we report draft genome sequence of B. melitensis strain 2007BM/1 isolated from human in India. METHODS: Genomic DNA was extracted from Brucella culture and was sequenced using an Illumina MiSeq platform. The generated reads were assembled using three de novo assemblers and the draft genome was annotated...
