Several species of aerobic sporulating bacilli recently isolated from soil, sewage, manure, and cheese, as well as authentic strains obtained from type culture collections, have been found to exhibit antagonistic activity against unrelated microorganisms. Cultures of these aerobic sporulating bacilli yield an alcohol-soluble, water-insoluble fraction,-tyrothricin,-which is bactericidal for most...

Background: Isolation of common pathogens involved in ocular infection and their in-vitro susceptibility to commonly used ocular antibiotics, as well as the trends in antibiotic resistance developed by these pathogens were investigated. Material/Methods: All patients with suspected bacterial ocular infections presenting between march 2010 and feb 2011 were examined under slit lamp microscope an...

conclusions all the staphylococcus aureus strains and enterococcus faecium strains were sensitive to members of the oxazolidinone class of linezolid drug. development of multi drug resistance by gram positive bacteria constitutes a very serious challenge for medical practice. despite these rising rates, it is impossible to distinguish where they have originated from and special attention has th...

Serious infections caused by Gram-positive bacteria are currently difficult to treat because many of these pathogens are now resistant to standard antimicrobial agents. As a result of the emergence and spread of multidrug-resistant Gram-positive pathogens, new antimicrobial agents are urgently needed for clinical use. In recent years, there has been an increase in the number of drugs that have ...

Suppression of type 17 immunity by type I interferon (IFN) during influenza A infection has been shown to enhance susceptibility to secondary bacterial pneumonia. Although this mechanism has been described in coinfection with gram-positive bacteria, it is unclear whether similar mechanisms may impair lung defense against gram-negative infections. Furthermore, precise delineation of the duration...

Staphylococcus epidermidis is a well-characterized, nonfastidious, aerobic gram-positive coccus commonly isolated in the clinical microbiology laboratory. Although coagulase-negative staphylococci, including Staphylococcus epidermidis, are often considered a contaminant in the clinical laboratory, an increasing number of reports describe their pathogenesis, in particular in infections of prosth...

Gram positive pathogens mainly Staphylococcus aureus, Enterococcus and Coagulase Negative Staphylococcus are hospital acquired (HA) pathogens. HA strains are usually multidrug resistant (MDR). Monitoring of these strains is essential in order to control their spread in the hospital environment and transmission to the community. The objectives were to assess the prevalence of Gram positive patho...
