The morbidity and mortality rates associated with Streptococcus pneumoniae remain very high worldwide. The virulence of this bacterium is largely dependent on its polysaccharide capsule, which is quite heterogeneous and represents a serious obstacle for designing effective vaccines. However, it has been demonstrated that numerous protein virulence factors are involved in the pathogenesis of pne...
متن کاملA Review on Environmental Mycobacteria in Iran
Abstract Mycobacterium genus, including pathogenic and environmental species, is called non-tuberculosis mycobacteria. In this review, we assessed the research about the frequency of non-tuberculosis mycobacteria in Iran. The analyses showed that there are 16 and 28 mycobacterial species isolated in water and soil samples, respectively. The most frequent mycobacterial species in water were M. f...
متن کاملPolar Localization of Virulence-Related Esx-1 Secretion in Mycobacteria
The Esx-1 (type VII) secretion system is critical for virulence of both Mycobacterium tuberculosis and Mycobacterium marinum, and is highly conserved between the two species. Despite its importance, there has been no direct visualization of Esx-1 secretion until now. In M. marinum, we show that secretion of Mh3864, a novel Esx-1 substrate that remains partially cell wall-associated after transl...

During the past decade, there has been a worldwide increase in occurrence of enterococcal infections. Though more than 28 enteroccocal species described, Enterococcus faecalis and Enterococcus faecium are isolated most frequently. This might be explained by t...
