Abstract
Out of 150 cockroaches examined in this study, 125 cockroaches (83. 33%) were infected with one or several species of external parasites (33.3) or gastro-intestinal helminthes (80%). The percentage infection and number of parasites of Cockroaches trapped in the toilets of houses more than infection of cockroaches trapped from the kitchens of houses (100% and 50%respectively) and 2-62 parasites/ml of Cockroaches trapped in the toilets while those trapped from the kitchens was1- 28 parasites/ml houses. A seven species were isolated from the external surface and intestinal tract represented two protozoa and five nematodes. This species were:Entamoeba blatti (33%), Nyctotherus ovalis (65.3 %), Hammersmiditiella diesingi (83.3 %), Thelastoma bulhoe (15.4 %), Gordius robustus (Horsehair worm) (1.3%), Enterobius vermicularis eggs , (2%) Ascaris lumbricoids eggs (1.3%). No Cestodes were records in the study. Prevalence of intestinal worms was statistically higher significant than the protozoa in (P<0.05). The number of worms per cockroaches ranged from 1-3 while protozoa 42 parasites/ml. Prevalence of endoparasites were higher than ectoparasites and intestinal worms was statistically higher significant than the protozoa in (80%; 3. 3%) and (83. 3%; 65.3 %) respectively.This study revealed Cockroach represent an important reservoir or carrier for medical importance parasites of human in houses as Enterobius vermicularis and Ascaris lumbricoids .The work presents the first record of cockroach's parasites in Al-Diwaniya.
