ترجمة الملخص

The aim of this study was concerned with the occurrence of water snails in some creeks of Karbala provinceIraq including Al-Husseinia, Al-Duwaihia and Al-Hunaidia creeks in addition to Musaida canal. The study also included investigation of infection of the snails with larval stages of digenean worms . Al-Husseinia creek was used as a major site for study, from which samples were collected during  6 months started from March to the end of August 2010. The water temprature in this creeks ranged from 17.8-30.8°c and it was a little tend to alkalinity, the pH values ranged between 7.1-8.3. The salinity values ranged from 0.79-0.91‰, while the turbidity ranged between 29-54 nephlometric, dissolved oxygen values ranged between 4.5-7.3 mg/L and water velocity between 16.84-20.84 cm/sec. In Al-husseinia creek The observed species of snails were observed  which are Melanopsis nodosa Ferussac, Theodoxus  jordani (sowerby), Physa acuta (Draprand) and Viviparous bengalensis (Lamarck), and the results revealed the dominance of M. nodosa during study period , the highest abundance and of this species was 261 individuals collected per one hour of time during August and species recorded percentage ranged from 55-78%,followed by the species V. bengalensis which recorded percentage ranged from 11-29%,while the species P. acuta was the lowest abundance which records a percentage ranged between 2-9% throught the study periods, while the percentage of the species T. jordani was recored percentage between 4-19% througth study periods.          Samples from Al-Duwaihia creek were collected during July and Augest 2010 ,five species of snails were observed in this site, That were Melanoidis tuberculata (Muller), M. nodosa, V. bengalensis, Lymnaea auricularia Linaeus, and P.acuta, and it was clear the M.nodosa was most abundance species giving 63.4% in the August followed by M.tuberculata, V. bengalensis , L. auricularia and P. acuta .        The third site was Al-Hunaidia creek, which is one of Al- Husseinia branches, located on the south-Karbala city, the samples were collected from this creek during July 2010. Four species of snails were observed in the water of this site which L. auricularia ,M. tuberculata, V. bengalensis and P.acuta. the species L.auricularia was the dominance which percentage reached to 81.8% in the same month.         The fourth site was Musaieda canal which branched from Beny-Hassan creek on the AL-Hindia town, the samples were collected from this canal during July 2010,six species of snails were observed in the water of this site which were L.auricularia , M. tuberculata , V. bengalensis , P. acuta and T. jordani . P. acuta was dominant species in this site giving values reaching to 64.96%.  Concerning snails infection with digenean larvae, in Al-Husseinia site 1773 individuals of M.nodosa ,54 individuals of P.acuta , 145 individuals of T.jordani and 244 individuals of V.bengalensis were examined.496 (27.98%) of M.nodosa infections were found, No other snails infections were found. In Al-Duwaihia site 142 individuals of M. tuberculata ,382 individuals of M. nodosa, 40 individuals of V. bengalensis , 26 individuals of L. auricularia and 14 individuals of P. acuta were examined. 30 (21.13%) of  M. tuberculata and 90(23.56%) of M. nodosa  infections were found, and no infections were found in other snails.  In Al-Hunaidia 184 individuals of L. auricularia ,20 individuals of M. tuberculata , 15 individuals of V. bengalensis and 6 individuals of P. acuta were examined, 36 (19.57%), of L. auricularia infections were found.     In Musaieda canal, 22 individuals of species L. auricularia ,76 individuals of species P. acuta ,4 individuals of species M. tuberculata , 6 individuals of species M. nodosa and 5 individuals of species T. jordani were examined, no snails species infections with any digenea larvae parasites were found. Eigth types of cercaria isolated from three species of snails which were M. nodosa , M. tuberculata and L. auricularia collected from different study sites.These types included Cercaria1(59.92%), Cercaria2 (12.81%), Cercaria 3(22.52%), Cercaria 4(1.03%), Cercaria 5(3.1%) and Cercaria 6(0.62%) were isolated from the first snails species in the Al-Husseinia creek. Types of the digenean larvae included Cercaria 1 (40%) Cercaria 7 (60%) were isolated from M. tuberculata and Cercaria 1(80%) , Cercaria 2(4.4%) , Cercaria 3(8.89%) and Cercaria 7(6.67%) were isolated from M. nodosa in Al-Duwaihia creek, while one types of parasite larvae which C9 were isolated from L. auricularia ,recoded in Al-Hunaidia creek. The results revealed double infections of two types of trematodes larvae in the species M. nodosa in the same time, in the Al- hussaeinia creek, which were (Cercaria 1+ Cercaria 2) in the March and April with percentages 9.52% and 2.75% respectively, infections with (Cercaria1+ Cercaria3) in May with percentage 1.02% and (Cercaria1+ Cercaria5) in July with percentage 1.79%.      And the statical analysis revealed significant positive correlation realationship between M. nodosa density and the infection percentages  with digenean parasite in Al-Husseinia and Al-Dhuwaihia creeks waters through study periods.
