LABORATORY DIAGNOSIS OF STAPHYLOCOCCUS AUREUS

A range of laboratory diagnostic methods has been developed to support patient management and disease control. The choice of diagnostic method depends on the purpose for which the testing is done (e.g. clinical diagnosis, epidemiological survey, vaccine development), the type of laboratory facilities and technical expertise available, costs, and the time of sample collection. Ideally,“LABORATORY DIAGNOSIS OF STAPHYLOCOCCUS AUREUS”

TOXINS AND PATHOGENESIS OF STAPHYLOCOCCUS AUREUS

TOXINS OF STAPHYLOCOCCUS AUREUS Staphylococcus aureus produces a wide variety of toxins which are important virulence factors and produces various diseases in humans. These are as follows: 1.) Hemolysin – Staphy aureus produces four antigenically distinct types of hemolysin called as alpha, beta, gamma & delta. All these types of toxin are exotoxins. Of these,“TOXINS AND PATHOGENESIS OF STAPHYLOCOCCUS AUREUS”
