Background & objectives: Staphylococcus aureus could produce different
toxins such as alpha, beta, and gamma-toxins and leukocidin Penton -
Valentine. Leukocidin (PVL) is a cellular toxin which acts against
polymorphonuclear cells, monocytes, and macrophages and causes an increase
in cellular membrane permeability and leukocytes lysis and tissue necrosis.
This study intends to determine the prevalence of PVL positive strainsof
Staphylococcus aureus by Real-Time PCR method.
Material & Methods: This descriptive study was done during the last 6
months of the 2011. 47 Staphylococcus aureus strains from the clinical samples
of Imam Reza Hospital and 53 strains from Shohada Hospital were collected
from Tabriz- Iran. Real-Time PCR method was done by using specific primers
and probes.
Results: From 100 Staphylococcus aureus isolates, 18 strains (18%) were PVL
positive. Eleven strains belonged to Imam Reza Hospital and 7 strains to
Shohada Hospital isolates.
Conclusion: By regard to producing PVL-toxins in Staphylococcus aureus
strains accounts as a serious threat for human health. So rapid and accurate
diagnosis of this gene in these bacteria is necessary. Therefore, it seems that
access a rapid and repeatable method will help in rapid diagnosis and timely
control of PVL- producing strains in clinical centers
