TY - JOUR ID - TI - Studying the Sensitivity of Bacteria Isolated From Respiratory Tract Infections To Peanut and Various Antibiotics دراسة حساسية البكتريا المعزولة من الإصابات النفسية للفول السوداني ومختلف المضادات الحيوية AU - ميسون صباح عباس AU - إنعام جاسم لفتة الجبوري AU - بان صاحب عبد النبي الناصري PY - 2011 VL - 29 IS - 16 SP - 672 EP - 681 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - The sensitivity of bacteria isolated from respiratory tract infections for variousantibiotics and peanut was studied. These bacteria included 5 gram- negativespecies: Klebsiella pneumoniae (1 isolate), K. oxytoca (1 isolate), Pseudomonasaeruginosa (6 isolates), Escherichia coli (2 isolates) and Neisseria meningitidis (1isolate), while gram- positive bacteria included: Staphylococcus aureus (6 isolates),Streptococcus pneumoniae (6 isolates), Micrococcus antarcticus, coagulasenegativeStaphylococci (CNS) and Corynebacterium spp., one isolate of each. Wetested the sensitivity of bacteria to 16 antibiotics as follows: Tobramycin (10 ìg),Ceftazidime (30 ìg), Vancomycin (30 ìg), Ampicillin (10 ìg), Cefaclor (30 ìg),Ofloxacin (5 ìg), Cloxacillin (1 ìg), Cefalothin (30 ìg), Erythromycine (15 ìg),Clindamycin (2 ìg), Oxytetracycline (30 ìg), Enrofloxacin (5 ìg), Neomycin (30ìg), Amoxicillin/Clavulanic acid (30 ìg),Ampicillin/ Cloxacillin (30 ìg) andCefotaxime (30 ìg). Also the sensitivity of bacteria to ethanolic extracts of peanut(Arachis hypogaea) was tested. We found that S. aureus was resistant to mostantibiotics (13 antibiotics), and was sensitive to vancomycin, ofloxacin andenrofloxacin. As well as S. pneumoniae which was sensitive to the same antibioticsabove in addition to ampicillin/ cloxacillin, while was resistant to 12 antibiotics. K.oxytoca was more resistant than K. pneumoniae and both were sensitive toenrofloxacin. Both E. coli and P. aeruginosa were resistant to 13 antibiotics andboth were more sensitive to tobramycin and ofloxacin . N. meningitidis resisted 9antibiotics , where as all of CNS , M. antarcticus and Corynebacterium spp. weresensitive to most antibiotics. When we studied the sensitivity of bacteria toethanolic extracts of Arachis hypogaea ,four isolate ofS. aureus were sensitive with zones of inhibition 7- 11 mm and two isolates werenegative. The growth of two isolates of S. pneumoniae was inhibited withinhibition zones of 8 and 10 mm, while 4 isolates were not inhibited. The herbextract recorded zone of inhibition of 8 mm in only one isolate of P. aeruginosa.
