The Possible Snail Intermediate Hosts of Dicrocoelium Hospes in Nigeria
Fashuyi S. A., G. O. Adeoye: The Possible Snail Intermediate Hosts of Dicrocoelium hospes in Nigeria. Acta vet. Brno, 55, 1986: 85 -88. Limicolaria /lammea. L. striatula and Lamellaxis gracilis were experimentally infected with larval stages of Dicrocoelium hospes after exposure to embryonated eggs. Limicolaria proved to be more suitable, showing higher infection rates, more mature cercariae an...
متن کاملHost diversity begets parasite diversity: bird final hosts and trematodes in snail intermediate hosts.
An unappreciated facet of biodiversity is that rich communities and high abundance may foster parasitism. For parasites that sequentially use different host species throughout complex life cycles, parasite diversity and abundance in 'downstream' hosts should logically increase with the diversity and abundance of 'upstream' hosts (which carry the preceding stages of parasites). Surprisingly, thi...
متن کاملMolecular characterisation of intermediate snail hosts and the search for resistance genes.
The relationship between schistosomes and their intermediate hosts is an extremely intricate one with strains and species of the parasite depending on particular species of snail, which in turn may vary in their susceptibility to the parasites. In order to gain a better understanding of the epidemiology of the disease we have been investigating the use of molecular markers for snail identificat...
متن کاملA method for the isolation of schistosome eggs and miracidia free of contaminating host tissues.
A novel method for the isolation of schistosome eggs and miracidia from livers of mice infected with Schistosoma japonicum or S. mansoni is described. The method employed collagenase B to degrade the interstitial matrix of mouse liver tissue, after which the schistosome eggs were separated from the liver cells by 2 single-step density centrifugations through Percoll. Using this procedure suffic...
متن کاملBiomphalaria tenagophila: genetic variability within intermediate snail hosts susceptible and resistant to Schistosoma mansoni infection.
DNA analysis by molecular techniques has significantly expanded the perspectives of the study and understanding of genetic variability in molluscs that are vectors of schistosomiasis. In the present study, the genetic variability of susceptible and resistant B. lenagophila strains to S. mansoni infection was investigated using amplification of their genomic DNA by RAPD-PCR. The products were an...
