Abstract
Background and objectives:
(ESBL) strain is one of the emerging health related problems in the world recently.
Some of the species of the gram-negative bacilli including Klebsiella Pneumonia &
Escherichia Coli are well known ESBL producing among bacteria, and they cause
uncontrollable infections. This Cross-sectional study was designed to asses the
ESBL producing gram negative bacilli among inpatients of Shohada-ye- ashayer
hospital (Khorram Abad).
Extended Spectrum Betalactamase producing
Materials and methods:
methods. ESBL producing gram negative bacilli were screened with MacConkey
Agars containing 4 mg/liter Ceftazidime and confirmed with double disk synergy
method as recommended by national standard laboratory institute.
Samples were processed with routine laboratory
Results:
positive for ESBL.The most isolated species of ESBL are 20 Klebsiella
pneumonia(8.88%), 10 Escherchiia coli(4.44%) and 10 pseudomonas
aeruginosa(4.44%). The most ESBL producing gram-negative bacilli were Isolated
from urine samples (21 cases 39.62%).and Ten cases (18.86%) from bronchoscopy
sterile samples.
Fifty- there cases (23.55%) of 225 total isolated gram negative bacilli are
Conclusion:
frequently isolated from Shohada-ye-Ashaier Hospital. Regarding the high
resistance of these strains against many of the antibiotics and even against
Carbapenems, health- care providers need to plan controlling policies for such
strains.
The Results indicate that ESBL producing gram-negative bacilli are
