520 | |a Introduction: In this study, we aimed to evaluate the macrolide-lincosamide-streptogramin B resistance phenotypes of methicillin-resistant Staphylococcus aureus strains isolated from patients in intensive care units (ICUs). Materials and Methods: A total of 50 MRSA strains isolated from clinical samples (45 blood, 5 tracheal aspirate) of patients in ICUs between 2013-2016 were included into the study. MLSB resistant phenotypes were investigated by D test method using erythromycin (15 μg Oxoid, UK) and clindamycin (2 μg Oxoid, UK) disks. Detecting resistance for both erythromycin and clindamycin were defined as constitutive MLSB (cMLSB), a flattening of the inhibition zone around the clindamycin disk proximal to the erythromycin disk (producing a zone of inhibition shaped like the letter D) as inducible MLSB (iMLSB), non-existence of D zone despite erythromycin resistance and clindamycin susceptibility as MSB, erythromycin and clindamycin susceptible strains as S phenotype. Results: Of all the 50 MRSA strains tested, resistance rates for erythromycin and clindamycin were as 84% and 48%, respectively. Among all tested strains, cMLSB, iMLSB and MSB resistance rates were detected as 57.1%, 35.7% and 7.1%, respectively. Eight strains were susceptible for both erythromycin and clindamycin and defined as S phenotype. Conclusion: iMLSB resistance in staphylococci can be detected easily in the microbiology laboratory by D test, which is an inexpensive but reliable method, by using clindamycin and erythromycin disks. Performing D test routinely in erythromycin resistant staphylococci strains and determining iMLSB resistance will prevent the inappropriate usage of clindamycin and will therefore play an important role in the prevention of treatment failures. | ||

MLSB resistant phenotypes were investigated by D test method using erythromycin (15 μg Oxoid, UK) and clindamycin (2 μg Oxoid, UK) disks. Detecting resistance for both erythromycin and clindamycin were defined as constitutive MLSB (cMLSB), a flattening of the inhibition zone around the clindamycin disk proximal to the erythromycin disk (producing a zone of inhibition shaped like the letter D) as inducible MLSB (iMLSB), non-existence of D zone despite erythromycin resistance and clindamycin susceptibility as MSB, erythromycin and clindamycin susceptible strains as S phenotype. Results: Of all the 50 MRSA strains tested, resistance rates for erythromycin and clindamycin were as 84% and 48%, respectively. Among all tested strains, cMLSB, iMLSB and MSB resistance rates were detected as 57.1%, 35.7% and 7.1%, respectively. Eight strains were susceptible for both erythromycin and clindamycin and defined as S phenotype. Conclusion: iMLSB resistance in staphylococci can be detected easily in the microbiology laboratory by D test, which is an inexpensive but reliable method, by using clindamycin and erythromycin disks. Performing D test routinely in erythromycin resistant staphylococci strains and determining iMLSB resistance will prevent the inappropriate usage of clindamycin and will therefore play an important role in the prevention of treatment failures.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Macrolide-lincosamide-streptogramin B</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Resistance phenotypes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Staphylococcus aureus</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Infectious and parasitic diseases</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Microbiology</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Salih Cesur</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Hatice Uludağ Altun</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Neziha Yılmaz</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">Flora Infeksiyon Hastalıkları ve Klinik Mikrobiyoloji Dergisi</subfield><subfield code="d">Bilimsel Tip Yayinevi, 2018</subfield><subfield code="g">22(2017), 1, Seite 29-33</subfield><subfield code="w">(DE-627)176059993X</subfield><subfield code="x">1300932X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:22</subfield><subfield code="g">year:2017</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:29-33</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.5578/flora.58638</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doaj.org/article/d1910ec955f042a6ba70b790d81bb589</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://www.floradergisi.org/getFileContent.aspx?op=REDPDF&file_name=2017-22-01-029-033.pdf</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">https://doaj.org/toc/1300-932X</subfield><subfield code="y">Journal toc</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">https://doaj.org/toc/1300-932X</subfield><subfield code="y">Journal toc</subfield><subfield code="z">kostenfrei</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_DOAJ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">22</subfield><subfield code="j">2017</subfield><subfield code="e">1</subfield><subfield code="h">29-33</subfield></datafield></record></collection>

Macrolide-Lincosamide-Streptogramin B Resistance Phenotypes in Methicillin Resistant Staphylococcus aureus Strains Isolated from Patients in Intensive Care Units |
abstract |
Introduction: In this study, we aimed to evaluate the macrolide-lincosamide-streptogramin B resistance phenotypes of methicillin-resistant Staphylococcus aureus strains isolated from patients in intensive care units (ICUs). Materials and Methods: A total of 50 MRSA strains isolated from clinical samples (45 blood, 5 tracheal aspirate) of patients in ICUs between 2013-2016 were included into the study. MLSB resistant phenotypes were investigated by D test method using erythromycin (15 μg Oxoid, UK) and clindamycin (2 μg Oxoid, UK) disks. Detecting resistance for both erythromycin and clindamycin were defined as constitutive MLSB (cMLSB), a flattening of the inhibition zone around the clindamycin disk proximal to the erythromycin disk (producing a zone of inhibition shaped like the letter D) as inducible MLSB (iMLSB), non-existence of D zone despite erythromycin resistance and clindamycin susceptibility as MSB, erythromycin and clindamycin susceptible strains as S phenotype. Results: Of all the 50 MRSA strains tested, resistance rates for erythromycin and clindamycin were as 84% and 48%, respectively. Among all tested strains, cMLSB, iMLSB and MSB resistance rates were detected as 57.1%, 35.7% and 7.1%, respectively. Eight strains were susceptible for both erythromycin and clindamycin and defined as S phenotype. Conclusion: iMLSB resistance in staphylococci can be detected easily in the microbiology laboratory by D test, which is an inexpensive but reliable method, by using clindamycin and erythromycin disks. Performing D test routinely in erythromycin resistant staphylococci strains and determining iMLSB resistance will prevent the inappropriate usage of clindamycin and will therefore play an important role in the prevention of treatment failures. |
