Over the past two decades Branhamella catarrhalis (now known as Moraxella catarrhalis) has come out as a major pathogenic bacteria in humans. Different researches have uncovered its association in respiratory tract infections (e.g., otitis media, sinusitis, pneumoniaandbronchitis). In children eye infections while in adultlaryngitis, bronchitis, and pneumonia commonly occurred. There is rising number of beta lactamase positive strains in this genus, we designed a study project in which we evaluated the sensitivity pattern of Moraxella catarrhalis isolated from sputum. Total 124 sputum samples were analysed. Confirmation was done by using chocolate agar a typical golden yellow which can be distinguished by hockey puck like colony. Further identifications were done by gram staining, oxidase test &other biochemical tests. Antibiogram was done by CLSI method. Sensitivity pattern showed Amoxicillinclavunate v 99%, Teicoplanin 49%, Ceftrioxone 01%, Erythromycin 30%, Trimethoprim -sulphamethoxazole 04%, Ciproflaxacin 50%,Cefexatin 84%. To control the resistivity of this organism some preventive measurements should be taken.
