Growth of Saccharomyces cerevisiae ure2Δ mutant strain was investigated in the presence of diverse oxidant compounds. The inability of the strain to grow on a medium supplemented with H2O2 was confirmed and a relationship between diminishing levels of glutathione (GSH) and peroxide sensitivity was established. Data for the lack of significant effect of URE2(More)
The response of Saccharomyces cerevisiae to arsenic involves a large ensemble of genes, many of which are associated with glutathione-related metabolism. The role of the glutathione S-transferase (GST) product of the URE2 gene involved in resistance of S. cerevisiae to a broad range of heavy metals was investigated. Glutathione peroxidase activity,(More)
Mycobacterium peregrinum is a member of the group of rapidly growing Nontuberculous Mycobacteria (NTM). It can be found in high frequency in natural and laboratory environments and is considered to be uncommonrare pathogen for both immunocompetent and immunosuppressed individuals. Currently, pulmonary infections caused by Mycobacterium peregrinum are(More)

The aim of the present study was to assess the prevalence of hepatitis B surface antigen among pregnant women in Varna Region, Bulgaria. During the period 2009-2013, an average prevalence of 2.26% (95%CI 1.75, 2.91) was measured in a total number of 2,700 samples. Analysis demonstrated that rural residence and minority ethnic origin are important risk(More)
http://www.journal-imab-bg.org / J of IMAB. 2015, vol. 21, issue 3/ ABSTRACT: Background: Mycobacterium gordonae is a slow growing mycobacterium usually found in soil, tap water, and as laboratory contaminant. It is occasionally implicated in different infections in immunosuppressed patients. In contrast, there have been few case reports of active infection(More)
BACKGROUND Human cytomegalovirus is a ubiquitous, large enveloped DNA β-herpesvirus that, like other herpesviruses, establishes lifelong latency following primary infection. It is the most frequent cause of congenital, neonatal and early postnatal infections with long lasting sequelae. AIM The aim of the present study was to assess the prevalence of(More)
BACKGROUND Varicella is a common and usually mild disease but it has great importance in regard to general infectious morbidity. The current study aimed to characterize possible risk factors of varicella epidemiology in Bulgaria, a country where infection follows its natural epidemiological pattern as no mandatory or recommended vaccine is currently(More)
Tuberculosis (TB) and HIV/AIDS infection are one of the most ubiquitous and deadli‐ est communicable diseases in the world. They cause millions of deaths each year and are recognized as major threats for public health worldwide. The corresponding pathogens (Mycobacterium tuberculosis and HIV) share overlapping epidemiology— they affect low-income countries(More)
Syphilis is a sexually transmitted disease with continuously rising rates among European countries. The vertical (mother to child) transmission is an important way of dissemination, often leading to stillbirth and permanent impairment of the newborn. We present a retrospective cross-sectional analysis of 2702 pregnant women tested for syphilis(More)
