Isolation of bacteria from milk and study the senestivity of bacterial isolates to antibiotic and medical plants

Abstract

This study was carried out to Isolation of bacteria from milk & study the senestivity of bacterial isolates to antibiotic & medical plants 100 milk samples.Were collected from Abu – Graib city in Baghdad samples culturing on different Media the result revealed that isolation rate was Staphylococcus aureus, , ( 31%) Streptococcus group D ( 73%), Escherichia coli ( 31%) Klebsiella SPP ( 13%)Pasteurella spp( 4%) Salmonella spp( 3%) . studying the senestivity of bacteria isolates to 8 types of antibiotic: (TOB) Tobramycin , Ceftazidime (CAZ) , Vancomycin (VA) , (SAM) Sulbactam Ampicillin , Cloxacillin (CX) , Cefalothin (KF) , Colistin (CL ), Amoxacillin Clavulanic acid(AMC) the result revealed that S. aureus & Streptococcus group D more sensitive to (KF) , E . coli more sensitive to (CL ) , Klebsiella & Salmonella more sensitive to (CAZ) , Pasteurella more sensitive to (TOB) . studying sensivity of bacterial isolates to alcoholic extracts of these plants: (Piper nigrum), cubeb seeds (Piper cubeba), (Cinnamomuum camphora), (Commiphora mol mol), seeds (Trigonella foenum- graecum) and seeds of Lepidium sativum. the result revealed that the bacterial isolates in this study more sensitive to alcoholic extracts of (Piper cubeba) & (Cinnamomuum camphora) . the other of alcoholic extracts had no inhibition effect on the bacteria isolated in this study
