Bac­terial species; general health care of the patient; and type of dental procedures are effective on the emergence of bacteremia complications. lessThan i greaterThan Moraxella catarrhalis lessThan /i greaterThan is an exclusively human commensal of the upper respiratory tract and oral cavity. As lessThan i greaterThan Moraxella catarrhalis lessThan /i greaterThan has been considered as a harmless commensal , very less is known about its pathogenic characteristics and virulence. However its role as a potential pathogen, has long been questioned. The aims of this study were to investigate the prevalence of transient bacteremia caused by lessThan i greaterThan Moraxella catarrhalis lessThan /i greaterThan after third molar impactions. Also to find whether lessThan b greaterThan lessThan /b greaterThan lessThan i greaterThan Moraxella catarrhalis lessThan /i greaterThan bacteremia can occurs even after prophylactic administration of Amoxicillin N.CHITRA Moraxella, bacteremia, third molar surgery, antibiotic resistance 609-615
