BACKGROUND Gonorrhoea and widely spread antimicrobial resistance (AMR) in its etiological agent Neisseria gonorrhoeae are major public health concerns worldwide. Gonococcal AMR surveillance nationally and internationally, to identify emerging resistance and inform treatment guidelines, is imperative for public health purposes. In 2009, AMR surveillance was(More)
The ultra-structure of Mycobacterium tuberculosis (MTB) was examined by transmission electronic (TEM)) and atomic force microscopy (AFM). The study was performed to describe the morphology of susceptible, multidrug-resistant (MDR), extensively drug-resistant (XDR) and extremely drug-resistant tuberculosis isolates (XXDR-TB) during their exponential growth(More)
The aim of this study was to investigate the frequency, location and type of katG mutations in Mycobacterium tuberculosis collected from patients in southern endemic region of Iran. Drug susceptibility testing was determined by using the BACTEC system and CDC standard conventional proportional method. All 28 isolates were resistant to isoniazid (100%),(More)
An immunochromatographic strip (ICS) test was developed for the detection of diphtheria toxin by using an equine polyclonal antibody as the capture antibody and colloidal gold-labeled monoclonal antibodies specific for fragment A of the diphtheria toxin molecule as the detection antibody. The ICS test has been fully optimized for the detection of toxin from(More)
OBJECTIVE Autoantibodies against C1q (anti-C1q) have been found in a number of autoimmune and renal diseases. They are best described in adult patients with systemic lupus erythematosus, where a strong correlation between the occurrence of anti-C1q and severe lupus nephritis (LN) has been observed. However, the role of anti-C1q in children with systemic(More)
Identification of Mycobacterium tuberculosis and M. bovis is necessary for the application of adequate drug therapy. PCR amplification is a good tool for this purpose, but choosing proper target is of a great concern. We describe a PCR assay for fast detection of M. tuberculosis and M. bovis.As a BLAST and BLASTP search we selected regulatory gene whiB7(More)
A total of 32 unimmunized children (median age 5 months) living in an orphanage in Minsk, Belarus, were vaccinated with three doses of oral poliovirus vaccine (OPV) with a 60-day interval between the doses. Blood samples were drawn before the immunizations and 45-50 days after each vaccine dose. Excretion of the vaccine viruses was followed by examining(More)
The mutation in KatG315 is found in the majority of isoniazid resistant strains worldwide, especially in areas with a high incidence of tuberculosis. A total of 138 isoniazid (INH)-resistant strains of Mycobacterium tuberculosis consisting of 108 MDR (multidrug resistant) and 30 XDR (extensively drug resistant) isolated from patients in different regions of(More)
