## Abstract Humans are a natural reservoir of __Staphylococcus aureus__ and asymptomatic colonization is far more common than infection. The aim of this work was to characterize genotypically 68 __S. aureus__ strains isolated from nasal swabs of healthy people and from human clinical infections. A

✦ Synopsis
Abstract
The majority of S. aureus strains isolated from beak‐swabs and pathological processes in chicken shows coagulation of human plasma (not of bovine plasma), crystal violet‐type A, hemolysine‐type A, formation of fibrinolysin, not formation of DNase and reactions with the experimental phage A1591. Because of the absence of DNase‐formation and the reaction‐specificity for phage A1591 we propose to designate these strains as host‐specific variety gallinae of S. aureus. The strains from chicken are compared with strains of human, bovine, and ovine origin. An ecological study in a chicken farm has shown that S. aureus strains from chicken are not found in man and vice versa.

## Abstract Staphylokinase is one of virulence factors produced by __Staphylococcus aureus__ strains. Producing it is associated with the presence of prophage in a bacterial cell which carries the __sak__ gene. In this study, we examined the ability to produce staphylokinase by 257 __S. aureus__ st
## Abstract __Staphylococcus aureus__ is a common infecting agent of many surgical sites. As a commensal organism to humans and rabbits, the infection process may occur due to native or exogenous __S. aureus__. We applied exogenous __S. aureus__ ATCC 49230 once weekly to the surgical site of an oss

An experimental and theoretical study was performed on the anti-staphylococcal activity of 18 natural and synthetic #avonoids against methicillin-resistant Staphylococcus aureus strains. The analysed #avonoids belong to three well-di!erentiated structural patterns: chalcones, #avanones and #avones.
Kanamycin nucleotidyltransferase (KNTase) catalyzes the transfer of the adenyl group from MgATP to either the 4Ј or 4Љ-hydroxyl group of aminoglycoside antibiotics. The steady state kinetic parameters of the enzymatic reaction have been measured by initial velocity, product, and dead-end inhibition
