The Corvus splendens (Indian house crow) normally fed on the garbage therefore, they have many pathogenic bacteria, which can infect the human and cause severe infection in human irrespective to the gender, age and region. The bacteria samples were isolated from the faeces, blood lever, and intestines of the crows in Luria-Bertani (LB) agar plates. The culture plates were incubated at 37 C until the colonies were appeared. The colonies were identified morphologically and through molecular marker using 16S-rDNA. The Commiphora myrrha plant extract was used to determine the antibacterial activities against the pathogenic bacteria isolated from crows. The plant was crushed with 70% methanol and filtered. The filtrates were dried and dissolved in 100% methanol. Antibacterial activities of plant extracts were determined against the pathogenicbacteria isolated from crows. The results showed that the plant extracts were very effective against the pathogenic bacteria and showed 100% antibacterial activities. The plants extracts were analyzed for the characterization of different antimicrobial compound through gas chromatography mass spectrometry (GC-MS). The undecane, tetrasiloxane, hexadecanoic acid, heptasiloxane, benzocyclohepten and many other compounds. The antibacterial activities of the plant extracts were might be because of their compound which had been reported previously as well as an antimicrobial compound.
