Larval stages of digenetic trematodes in Melanopsis praemorsa snails from freshwater bodies in Palestine.
OBJECTIVE To detect the species of larval trematodes (cercariae) in Melanopsis praemorsa snails from 5 different fresh water bodies in Palestine. METHODS A total of 1 880 Melanopsis praemorsa snails were collected from different fresh water bodies in Palestine from October, 2008 to November, 2010. Cercariae in Melanopsis praemorsa snails were obtained by lighting and crushing methods. The beh...

متن کاملThe Helminth Parasites of Birds , Iii : Dicrocoeliid Trematodes from North American Birds
During the past several years we have examined, for helminth parasites, more than 700 specimens of wild birds, which represent 14 orders, 40 families, and 134 species. Although the avian hosts came from various localities throughout the southeastern section of the United States, the greater concentrations were collected from State College, Miss. ; Athens and Augusta, Ga. ; Highlands, N.

متن کاملDetermination of the infection of Lymnaea-gedrosina to trematodes Larval in the water region of Khuzestan
Background & Objective: The province of Khuzestan with its wide geographical area and its tropical climate is susceptible for the maintenance of snails. One of the prevalent intermediate hosts for trematode in this area is the gasteropode snail, Lymnaea gedrosina. This study is the first research, undertaken to determine the infection rate, biological characteristics and Longevity Lymnaea gedro...
متن کاملCommunity Structure : Larval Trematodes in Snail Hosts
In species assemblages of larval trematodes in individual snail hosts, fewer multispecies infections are observed than might be expected by chance. Both interspecific competition and the isolating effect of heterogeneity inrecruitment may explain this pattern of community structure. Here, we analyzed the expected and observed frequency of double infections, using data culled from 62 studies. Ou...
