PCR diagnosis of Fasciola hepatica in field-collected Lymnaea columella and Lymnaea viatrix snails.
Fasciolosis, caused by the trematode Fasciola hepatica, is a zoonosis of economic importance in livestock that is emerging as a chronic disease in humans. The intermediate hosts are lymnaeid snails, in which diagnosis of infection is traditionally based on cercarial shedding, tissue sectioning and crushing. We developed a PCR assay for the sensitive and specific detection of F. hepatica in fiel...
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 کاملSympatric and allopatric combinations of Lymnaea columella and Fasciola hepatica from southern and south-eastern Brazil.
Experimental infections of Lymnaea columella with Fasciola hepatica were carried out to test the effect of sympatric and allopatric combinations between parasite and host, by using snails and flukes from southern and south-eastern Brazil. Four groups of 50 snails were infected with four miracidia per snail: two groups in sympatric and two groups in allopatric combinations. Sympatric combination...
متن کاملRearing of Lymnaea columella (Say, 1817), intermediate host of Fasciola hepatica (Linnaeus, 1758).
The intermediate host of Fasciola hepatica, Lymnaea columella, collected in Belo Horizonte, Minas Gerais, Brazil, was reared in our laboratory. The aim of the current study was to standardize a rearing and maintenance technique. Two kinds of diet were tested: fresh lettuce (A) and rodent ration + 10% CaCO3 plus fresh lettuce (B). The age for the beginning of oviposition ranged from 27 to 57 day...
متن کاملDetection of Lymnaea columella infection by Fasciola hepatica through Multiplex-PCR.
From complete mitochondrial DNA sequence of Fasciola hepatica available in Genbank, specific primers were designed for a conserved and repetitive region of this trematode. A pair of primers was used for diagnosis of infected Lymnaea columella by F. hepatica during the pre-patent period simultaneously with another pair of primers which amplified the internal transcribed spacer (ITS) region of rD...
