RESUMO
The prevalence of parasitic helminths in 20 stray dogs from the area of Baghdad was recorded. Taenia spp. were found in 12 dogs, Dipylidium caninum in ten dogs, Toxocara canis in eight dogs, Ancylostoma caninum in seven dogs and Echinococcus granulosus in five dogs. Spirocerca lupi and Dirofilaria immitis were found in three dogs, Mesocestoides lineatus in two dogs and Strongyloides stercoralis in one dog.

The prevalence of infection with hydatid cysts in sheep, goats, cattle and camels slaughtered at Baghdad Abattoir was recorded over a period of 18 months. The infection rates were generally lower than had been reported in previous surveys but remained high in camels. The lower prevalence rates were attributed to the destruction of stray dogs, improved standards of meat inspection and an overall improvements in socio-economic conditions. The fertility rate of the cysts was higher in camels than in sheep or goats. All the cattle cysts were sterile.

The response of Awassi sheep to primary infection with 10 000 Haemonchus contortus larvae and subsequent challenge with 20 000 larvae was studied. Two types of response to re-infection were observed. The first, characterized by a sharp decline in egg counts, progressive improvement in packed cell volume (PCV) and a marked loss of adult worms and challenge larvae, was considered as self-cure and protection. In the second type of response there was a temporary decline in egg counts, no improvement in PCV and necropsy findings indicated hyper-infection with challenge larvae.

Three of the most common species of aquatic snails in Iraq were examined for their susceptibility to infection with Paramphistomum cervi. Bulinus truncatus was the only susceptible species. No development occurred in Physa acuta or Lymnaea lagotis euphratica. These findings and a previous field observation that infection of B. truncatus with amphistome larvae is not uncommon indicate that B. truncatus is an intermediate host of P. cervi in Iraq. Young snails of B. truncatus were more susceptible to infection than older ones.
