fa شناسایی باسیلهای گرم منفی مولد بتالاکتاماز طیف وسیع از باکتریهای جدا شده از موارد بالینی Screening of Extended Spectrum Beta lactamase Producing Gram Negative Bacilli Isolated from Clinical Cases 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 Key words:   Extended Spectrum Betalactamase.
