Nasal colonization of mecA-positive, oxacillin-susceptible, methicillin-resistant Staphylococcus aureus isolates among nursing staff in an Iranian teaching hospital

Colonização bacteriana e resistência antimicrobiana em trabalhadores de saúde: revisão integrativa

“…The studies were published in 2008, (22) 2009, (14,15) 2010, (25) 2011, (23) 2012, (21) 2013, (12,13,16) 2014, (14,15,18) 2016, (20) 2017, (24) all in English. (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) In terms of level of evidence, 13 articles were cross-sectional, observational studies (level of evidence 6), (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) whereas one was a cohort study (level of evidence 4).…”

“…(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) The main data collection sectors in the articles were intensive care units, (17,22,25,27) emergency departments, (12,17,18) operating rooms, (17,22) and hemodialysis and nephrology units. (22) To detect colonizing microorganisms, the samples were collected through nasal swab specimen techniques, (12)(13)(14)(15)(20)(21)(22)(23)(24) as well as from saliva (17,19) and the hands. (18) Some studies collected samples from more than one anatomic site.…”

“…(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) (19,25) Of the samples with colonization by Staphylococcus aureus, some researchers isolated strains of methicillin-resistant Staphylococcus aureus (MRSA) from strains that were susceptible to methicillin (MSSA). (12,13,15,17,18,21,24) These strains of MRSA were resistant to antibiotics such as ciprofloxacin, (12,17) clindamycin, (12,17,21) pristinamycin, (13) oxacillin, (13,17,21,24) penicillin G, (15) ampicillin, (15) amoxicillin, (15) tetracycline, (13) erythromycin, (17,21) mupirocin, (21) sulfamethoxazole (21) and cefoxetin. (17) A study which considered Staphylococcus aureus as the colonizer of its samples and did not separate the MRSA and MSSA strains noted there was resistance to Imipenem.…”
