Detection and expression of SapS, a class C nonspecific acid phosphatase with O-phospho-Ltyrosine- phosphatase activity, in Staphylococcus aureus isolates from patients with chronic osteomyelitis

ABSTRACT:

Introduction

The identity of Staphylococcus aureus virulence factors involved in chronic osteomyelitis remains unresolved. SapS is a class C non-specific acid phosphatase and a well-known virulence factor that has been identified in S. aureus strain 154 but in protein extracts from rotting vegetables.

Objective

To identify the SapS gene and characterize the activity of SapS from S. aureus strains: 12 isolates from bone infected samples of patients treated for chronic osteomyelitis and 49 from a database with in silico analysis of complete bacterial genomes.

Materials and methods

The SapS gene was isolated and sequenced from 12 S. aureus clinical isolates and two reference strains; 49 S. aureus strains and 11 coagulase-negative staphylococci were tested using in silico
