Molecular characteristics and virulence gene profiles of Staphylococcus aureus causing bloodstream infection 55
Li,Xuehan; Fang,Fang; Zhao,Jin; Lou,Ning; Li,Chenglin; Huang,Tao; Li,Yirong.
ABSTRACT Background: The rate of methicillin-resistant Staphylococcus aureus (MRSA) among the total of S. aureus isolates decreased to 35.3% in 2017 in China. It is unclear whether the molecular characteristics of S. aureus isolates have changed as the rate decreased. Objective: This study aimed to investigate the molecular characteristics and virulence genes profile of S. aureus isolates causing bloodstream infection and analyze the correlation between the prevalence rates of the common sequence types and MRSA. Methods: A total of 112 S. aureus strains from eight hospitals of four cities, including 32 MRSA isolates, were identified and evaluated through multilocus sequence typing, spa typing, and determination of virulence genes. Results: Twenty-five...

Staphylococcus aureus nasal carriage among outpatients attending primary health care centers: a comparative study of two cities in Saudi Arabia and Egypt 55
Shady,Hala M. Abou; Bakr,Alaa Eldin A.; Hashad,Mahmoud E.; Alzohairy,Mohammad A..
Epidemiological and molecular data on community acquired methicillin resistant Staphylococcus aureus(CA-MRSA) are still scarce in both Egypt and Saudi Arabia. There is almost no data regarding methicillin resistant Staphylococcus aureus (MRSA) prevalence in both countries. This study was conducted to investigate the prevalence and molecular epidemiology of S. aureusand MRSA nasal carriage among outpatients attending primary health care centers in two big cities in both countries. A total of 206 nasal swabs were obtained, 103 swabs from each country. S. aureusisolates were characterized by antibiotic susceptibility, presence of mecAand PVL genes, SCCmec-typing and spa typing, the corresponding Multi locus sequence typing clonal complex was assigned for each...
