The liver fluke, Fasciola hepatica, is considered as the most common cause of fasciolosis in both domestic livestock and human. This study was carried out to detect the prevalence of the larval stages of F. hepatica in the snails Galba truncatula and Lymnaea stagnalis in West Azarbaijan, Iran. Snail collection was performed through searching 28 freshwater habitats from May to December 2010. Fol...

A naturally occurring Salmonella mikawasima serologically converted by phage 14 (6,7,14:y:e,n,z15) has been isolated for the first time. An S. tennessee variant seroconverted by phage 14 (6,7,14:z29:-) was also isolated. The source of these salmonellae was the common freshwater aquarium snail Ampullaria. Phage 14 prepared from these serovariants was lytic for S. bovis-morbificans (6,8:r:1,5) an...

The biological control of freshwater snail hosts of schistosome parasites has attracted much attention in recent years, but the efficiency of such bio-control agents has rarely been tested outside laboratory conditions. The present paper attempts to summarize the present status of biological control of snails intermediate hosts, to indicate some major gaps in our knowledge of this subject, espe...

We characterized 10 variable microsatellite loci in the freshwater snail Biomphalaria kuhniana, as well as conditions for multiplexing and co-loading sets of loci. Two to five alleles were detected per locus over the two studied populations in Venezuela. High inbreeding coefficients suggest high selfing rates. Cross-species amplification provided some variability at eight and three loci in the ...

The red-rimmed melania or Malaysian Trumpet Snail, Melanoides tuberculata, is a common exotic freshwater snail that has been invading an increasing number of water bodies in North America. As well-known host for trematodes causing human and animal diseases, the pattern invasion parasitic infection this species great concern. Snail specimens were collected from urban stream Los Angeles drains in...

Disease distribution is correlated to the of freshwater snails which in turn influenced by physicochemical status habitats. This study aimed evaluate snail species diversity, abundance, and KwaZulu-Natal (KZN) province, South Africa, between December 2020 February 2021. A total 4576 consisting 8 were collected from 127 sites 11 districts. Tarebia granifera most abundant (n = 2201), while bivalv...

Problem: It is often assumed that the heritability of performance traits (function) can be estimated by the heritability of primary traits (e.g. form). It is also frequently assumed that performance traits should be less heritable than primary traits. These assumptions should be carefully evaluated rather than assumed. One common area of study in which these assumptions have been made is anti-p...

The present communication deals with the distribution and population fluctuation of Indoplanorbis exustus under the impact of variant abiotic factors in Doon Valley, Uttarakhand. Further the study also revealed the effects of some physico-chemical parameters, like pH, water temperature, dissolved oxygen, free carbon dioxide on the occurrence and abundance of snail Indoplanorbis exustus in the v...

The use of snails as biocontrol agents against other snails and against aquatic weeds is reviewed, evaluating their success and their impacts on non-target organisms. The predatory snail Euglandina rosea (and other species), although widely used against Achatina fulica (the giant African land snail) on Pacific and Indian Ocean islands, has not been shown to control A. fulica but has seriously i...
