Evaluation of efficiency of some disinfectants and antibacterial agents on bacterial pathogens isolated from post-operative wounds

Abstract

The most likely organisms to infect clean operation wounds in hospital are Staph. aureus, Pseudomonas. aerugionsa, and Eschericia.coli, as with accidental wounds local treatment often sufficient.Evaluation the effects of plant extracts of Myrtus communis, Eucalyptus, and Nerium oleander on the types of bacteria , in comparison with the standard antibiotics .A total of 40 specimens were collected from surgery units of teaching Hospital, and AL-Basrah General Hospital during Sep 2007 to April 2008. Four disinfectants :Hibitan, Septol, providine Iodine, and savlon, plant extracts of Myrtus communis, Eucalyptus, and Nerium oleander, in comparison with the standard antibiotics were testing against bacterial pathogens associated with postoperative wounds. From a total of (40) post operative wounds 72.5% are positive cultured cases, while 27.5% are negative cultured cases.Staph. aureus and pseudomonas spp are bacteria in percentage (75.86), while protease is the lowest isolated from (20.68%) from all positive cases.Four disinfectants (Hibitan, Septol, Iodine, and savlon), and three plant extracts of Myrtus communis, Eucalyptus, and Nerium oleander, and eight standard antibiotic were used for determine antibacterial activity of its.Most diluted concentration of disinfectants, lowest con. Of extracts, and some antibiotics are not effective on the bacterial types effects plant extracts are locate within the limits of studied antibiotics that give inhibition zones between 10-30 mm against all bacterial pathogensThere are avariety of effects of various disinfectants in comparison with plant extracts and antibiotics against bacterial pathogens associated with postoperative wounds.
