Background & Aim: In the previous years, CTX-M extended spectrum β-lactamases (ESBLs) have emerged worldwide and have
replaced classical TEM and SHV-type ESBLs in many countries. CTX-M-15 is currently the most frequent, with a pandemic
distribution, and the rapid spread is facilitated by incorporation of resistance genes in mobile genetic elements. This successful ESBL
in Gram negative bacteria is closely associated with nosocomial environments and as an intestinal colonized, particularly in old and
dependent patients. Little is known about the CTX-M ESBLs among Klebsiella pneumonia in Adjara. Our goal is the detection and
characterization of ESBLs among Klebsiella pneumonia isolates from patients in two different hospitals in Adjara.
Material & Methods: Susceptibility profile and identification of the infection of Klebsiella pneumonia (n=23) isolates collected from
different hospital services (2013-2015) were performed by disc diffusion methods according to the CLSI guidelines and API 20E,
respectively. ESBL producers were detected and/or confirmed by the double disk synergy test using oximino-β-lactamic antibiotics
with and without clavulanic acid. Genes of families’ blaTEM, blaOXA, blaSHV and blaCTX-M group 1 were investigated by PCR. Sequencing
was performed using group specific primers for CTX-M group 1.
Results: Fourteen Klebsiella pneumonia producing CTX-M group 1 ESBL infection isolates were detected in different biological
samples, namely in sputum (n=8), urine (n=5) and abdominal fluid (n=1), collected in different hospital services. The infection
isolates showed an extended resistance profile to aminoglycosides, fluoroquinolones and tetracycline. CTX-M group 1 ESBL isolates
showed specific amplification for blaTEM, blaOXA and blaSHV families.
Conclusion: This is the first report of CTX-M group 1 in infection Klebsiella pneumonia isolates in Adjara. This situation might
represent the spread of these multidrug resistant Gram negative in acute care hospital in Adjara. The implementation and/or
reinforcement of infection control measures, active antibiotic resistance surveillance and colonization screening of high risk patients
is important in order to limit the dissemination of CTX-M ESBL producing Klebsiella pneumonia in health care institutions and to the
people of Georgia. Colonization screening in elderly and/or dependent patients, upon admission at different health care institutions
and their evaluation before discharge are extremely important to prevent the spread of cycle of multidrug resistant Klebsiella
pneumonia in various healthcare facilities.
