Antimicrobial Resistance Pattern of Moraxella catarrhalis and Haemophilus influenza in Iran; a Systematic review

Abstract

Introduction: Haemophilus. influenzae and Moraxella. catarrhalis are two common pathogens in respiratory tract infections. Antimicrobial resistance to these pathogens occurs over years. Therefore, we decided to carry out a systematic review to investigate the antibiotic resistance and sensitivity of these pathogens in Iran.Material and method: All recent original articles and studies related to the antimicrobial resistance in H. influenza and M. cattarhalis in Iran up to 2022 were investigated in English and Persian databases. Result: The prevalence of antibiotic susceptibility in H. influenza to levofloxacin (100%), cefotaxim (78.8%), clarithromycin (71.4%) and ceftriaxone (71.4-80%) was upmost. Resistances to ciprofloxacin were varied. In addition, about 50% of isolated had resistant to ampicillin. The prevalence of M. cattarhalis resistance in Iran including penicillin was 70-100%, erythromycin was 0%, and in three of our study of our studies, the resistance rate of ciprofloxacin was 0% whereas in one study 70% of isolated M.cattarhalis had resistance to ciprofloxacin also, resistances to amoxicillin/clavulanate were varied.Conclusion: According to the study, most isolates of H. influenzae are sensitive to levofloxacin, but resistance to macrolides and third generation cephalosporins are increasing; and the majority of M. cattarhalis was resistant to penicillin.
