Abstract:
The article deals with analysis of a detection frequency and antibacterial treatment resistance of
Acinetobacter spp.of different species affiliation. Strains of bacteria detected in patients with pyo-
inflammatory complications after surgeries (period from 2010 to 2012) were involved in the study. 137 strains
of Acinetobacter spp. were detected and studied. Fraction of Acinetobacter spp. in 2010, 2011 and 2012 was
2.3, 3 and 3.4% respectively. Fraction of P.aeruginosain all non-fermentative Gram-negative bacteria
(NFGNB) decreased by 120% and fraction ofAcinetobacter spp. increased by 200-250%. Acinetobacter
spp.detection frequency was not significantly changed in the period from 2006 to 2012. However the fraction
of Acinetobacter spp. in NFGNB increased by 150% and was 29% in 2012. Detection frequency of
A.baumanii sharply increased in 2012. A study of antibacterial treatment resistance of Acinetobacter spp. (10
antibacterial medicines) showed that Polymyxin B and E (Colistin) was the most effective medicine for
A.baumanii and A.calcoaceticus infection. 85-95% of Acinetobacter spp.strains kept sensitivity to this
antibacterial medicine. 66-88.9% of A.baumaniistrains, 66.7-81.8%of A. alcoaceticus and 66.6% of other
Acinetobacter spp.weresensitive to Tigecycline. Dioxidine effectiveness was close to Tigecycline in 66.7-80%
of A.baumaniistrains. 85-100% of A.calcoaceticusstrainswere sensitive toDioxidine. There is a trend of
decreasing of A.baumaniisensitivity toCarbapenems by 200%. Fraction ofstrainssensitive toMeropenem and
Imipenem in 2012 was 21.4% and 16.7% respectively. All studied strains of A.lwoffii and A.haemolyticuskept
sensitivity toCarbapenems. In 2012 23.8% of A.baumaniiand 50% of A.calcoaceticusstrains were sensitivity
toAmikacin, meanwhile A.lwoffii and A.haemolyticus were not sensitive to this medicine. 31.3% of
A.baumaniiand 50% ofA.calcoaceticus strains were sensitive to Ceftazidime/Sulbactam. 5.3% of A.baumanii
and 15.8% of A.calcoaceticus strains were sensitive toPiperacillin/Sulbactam. Gentamicin effectiveness was
fixed in 12.5% of A.baumanii and 45.5% of unidentified Acinetobacterstrains.Gentamicin was not effective
against A.lwoffii and A.haemolyticus. Thus Polymyxins (in monotherapy or in combination with
glycopeptides), Dioxidine and Tigecycline in combination with Carbapenems or Ceftazidime/Sulbactam are to
be drugs of choice in treatment for pyo-inflammatory complications caused by Acinetobacter spp.
