Background:
Methicillin resistant
S. aureus
(MRSA) is
responsible for hospital (HA-MRSA) and community-acquired
infections (CA-MRSA). MRSA strains were identified after
the introduction of methicillin in therapy. The purpose was
to evaluate the antibiotic resistance phenotypes of CoNS
strains isolated from hospitalized patients.
Materials & Methods:
The study included strains isolated
from hospitalized patients in the Emergency Hospital
Prof. Dr. O Fodor Cluj-Napoca. The identification and the
antibiotic resistance profiles of the strains were performed
by standard and automated methods (ApiStaph galery and
Vitek2Compact).
Results:
Of all isolates, 37.5% were CoNS:
S. epidermidis
(20.8%),
S. intermedius
(4.2%),
S. capitis
(2.1%),
S. hominis
(2.1%),
S. haemoliticus
(4.2%),
S. saprophyticus
(2.1%) and
other CNS (2.1%). Fromall the CNS strains, 26 strains (27.18%)
showed Meticiline resistance (MR). The CNS strains showed
high rates resistance to Penicillin (25%), to Erythromycin
(22.9%), to Imipenem (16.7%), to Rifampycin (10.41%) and to
Fosfomycin (29.16%). The CNS strains resistant to Meticiline
were:
S. Epidermidis
(20.8%),
S. Intermedius
(4.2%),
S.
Haemoliticus
(4.2%),
S. saprophyticus
(2.1%) and other SCN
(21%). The MR CNS strains were resistant to Eritromycin
(14.6%), Clindamycin (14.6%), Ciprofloxacin (16.7%),
Gentamycin (16.7%), Rifampycin (14.6%), Tetracyclin (25%)
and Imipenem (22.9%). The resistance to Moxifloxacin was
10.41%. All strains were susceptible to Teicoplanin and
Vancomycin.
Conclusion:
Following the strains antibiotics resistance
profile, we conclude to the circulation in our geographic area
of strains with different resistance phenotypes. This finding
indicates the necessity to detect them by PCR, for limiting
the spread of these strains in hospitals and community.
