Staphylococcus aureus is a major human pathogen associated with nosocomial respiratory tract infections in health care settings, particularly in critical care units. Pathogenesis of S. aureus is contributed to the expression of cell surface protein receptors for Microbial Surface Components Recognizing Adhesive Matrix Molecules (MSCRAMMs) that interact specifically with proteins present in the host plasma and extracellular matrix.[1] Fibronectin-binding proteins (FnBPs) A and B are two of the multifunctional MSCRAMMs of S. aureus, which recognize fibronectin, fibrinogen, and elastin. In this study we have taken 20 clinical isolates of S. aureus which were subjected to antibiotic sensitivity pattern followed by the detection of fnbA gene by PCR. We have observed total resistance to penicillin followed by other group of drugs. 10% of our strains were found to have this gene. This indicates that the presence of this gene has the direct correlation with respiratory tract infections.Keywords

Esp gene is a high molecular weight surface protein whose frequency is significantly increased among infection derived Enterococcus faecalis isolates. Esp gene is an Enterococcal surface protein gene which is present in the opportunistic pathogens Enterococcus faecalis and Enterococcus faecium. It has been proposed that esp gene can be used as a marker of human pollution in environmental waters. This gene has been shown to be a part of a 150-in putative pathogenicity island. A sum of 20 isolates of Enterococci were assessed for the presence of esp gene that encodes for extracellular surface protein. We have observed 5% positivity in our study. This indicates that, the pathogenicity of urinary tract infections by these pathogens might be crucially played by this gene encoding for extra cellular surface protein.Keywords

Bacteriophage has been a known virus from many years and one of the most abundant viruses present. Preying only on bacteria, they don't harm human body. Since many years bacteriophage studies are being carried out. Recent studies shows that bacteriophage are proving to be beneficial to human body. They act as immune barriers with mucus in human body. Also these viruses are playing an important role in vaccines. One of the main recent advancement shows Bacteriophage Therapy which includes dentistry also. This review throws a light on importance of these bacteriophages in science.Keywords

PVL and γ -haemolysin are considered to be members of a toxin family known as synergohymenotropic toxins, as they act on cell membranes by the synergy of two proteins that form a pore. Only 2% of S. aureus isolates produce PVL, while γ -haemolysin is produced by more than 99% of S. aureus isolates. PVL is the most leukocytolytic toxin in the family, however it does not exhibits no haemolytic activity on human erythrocytes. A sum of 20 clinical isolates of S. aureus were subjected to antibiotic sensitivity pattern followed by the detection of pvl gene by PCR. We have observed increased resistance to most of the routinely used antibiotics and 10% of our isolates found to have pvl gene. As this gene is directly associated with skin and soft tissue infections by S. aureus, our two isolates may even cause such infections, although none of these strains were not obtained from cutaneous lesions.Keywords
