Abstract:
LC50 for heavy metals Cadmium, Lead, Cobalt, Nickel, Silver and Mercury to two snails species Lymnaea auricularia and Physa acuta had been Estimated during 96 h. LC50 was high for Lead 9.667 ppm for Physa acuta and low for Mercury 0.281 ppm for Lymnaea auricularia. significant correlations for LC50 had been found between Lymnaea auricularia and Physa acuta . heavy metals toxicity followed this order Pb < Cd< Ni< Co< Ag <Hg. Mortality percentage did not occur for strontium on study snails with concentration from 1 until 30 ppm.

Abstract:
SUMMARYMethodology is described for the laboratory maintenance of the life-cycle of Sanguinicola inermis, using common carp (Cyprinus carpio) as the definitive host and Lymnaea peregra as the intermediate host. Lymnaea auricularia was also infected but is not considered to be a suitable laboratory host. Tench (Tinca tinca) were susceptible to infection at high cercarial doses but subsequent infection rates were low. Goldfish (Carassius auratus) and Lymnaea stagnalis were refractory to laboratory infection.

Abstract:
Radix auricularia (Lymnaea auricularia) snails are the main intermediate host of Fasciola gigantica in the middle and South of Iraq. Recently, some studies suggest these snails are not present in Iraq, in particular Basrah province. Thus, the current study was aimed to use the bioinformatics analysis in the determination of Radix sp. in Basrah and also aimed to identify morphological characteristics of this species in the AL-Sewaib river, Basrah. Four hundred R. auricularia snails were collected from the AL-Sewaib river during May 2018 to March 2019. The results of the bioinformatics analysis

Different species of vector snails carry larval stages of different trematodes. Studies were performed to investigate different snail species and parthinate of trematodes carried by them, in some selected areas of Mymensingh Sadar, Mymensingh. Snails were collected by hand picking method and examined after crushing. Among 864 tested snails, it revealed the presence of six species of snails like Lymnaea auricularia 145 (16.8%), Lymnaea luteola 205 (23.7%), Indoplanorbis exustus 273 (31.6%), Vivipara spp. 164 (18.9%), Brotia spp. 35 (4.1%) and Pila spp. 42 (4.8%) in the study areas.

The causative agents&#x0D; of cercariasis consist of two clearly differentiated cercariae groups: Schistosoma and&#x0D; Bilharziella.
