ANTAGONISTIC ACTIVITY BETWEEN BACTERIAL SPECIES CARRIED BYADULT HOUSE FLY MUSCA DOMESTICA

Abstract

This study dealt with the isolation and identification of Gram-positive and Gram- negative bacterial
species for 300 samples house fly Musca domestica .L associated with external surface and its body
parts , collected from different areas of kirkuk city including (Kirkuk general hospital , AL-Tapa waste
near the house, Khan- Al-Tamr area , Domez area ,which included vegetable and meat markets ). The
following bacterial species were isolated from the right wing : B.subtilis , Staph.aureus, Staph
xylosus,Micrococcus luteus, Pseudomonas flurescence, E.coli ,K.oxytoca,,P.vulgaris,Acintobacter.spp .
from the left wing the following species were isolated : Bacillus.spp,Strep.iniae,Aerococcus viridansP.
flurescence,Acintobacter.sppandthebodysurfacethesespecieswereisolated:B.cereus,Staph.saprophyticus,
Staph.aureus,P.aeroginosa,E.coli ،K.oxytoca,Serratia fonticola, Hafnia alvei, Enterobacter.spp. The
microbial antagonistic activity was also studied of the bacterial isolates isolated from the right wing
was studied on bacterial isolates from the left wing and vice versa . the results showed that some
isolates showed their ability to inhibit the growth of some other species , the isolates of B.subtilis
isolated from the right wing and Pseudomonas flurescence.
