SOHAIL, Muhammad  and  LATIF, Zakia. Prevalence and antibiogram of methicillin resistant Staphylococcus aureus isolated from medical device-related infections; a retrospective study in Lahore, Pakistan. Rev. Soc. Bras. Med. Trop. [online]. 2017, vol.50, n.5, pp.680-684. ISSN 0037-8682.


With the advancement of medicine and surgery, various types of medical devices have become part of treatment strategies.


Identification and antimicrobial sensitivity testing were done according to CLSI guidelines following standard microbiological practices.


Urinary catheter infections (31%) were most frequent followed by central venous catheter (18%) and orthopedic implants (15%). Methicillin resistant Staphylococcus aureus (MRSA) was a major cause of device-related infection after Escherichia coli (21%); other pathogens were Klebsiella pneumoniae (14%), Pseudomonas spp. (10%), Acinetobacter spp. (8%) and Candida species (7%). None of MRSA was resistant to vancomycin (MIC ≥16µg/mL). Resistance rates were 98% and 97% for ofloxacin and ciprofloxacin, respectively.


Escherichia coli and MRSA are major pathogens of medical device-related infections.

Keywords : Prosthetic devices; MRSA; Escherichia coli; Vancomycin; Antibiogram.
