Invasive Black Carp as a Reservoir Host for the Freshwater Mollusk Parasite Aspidogaster conchicola: Further Evidence of Mollusk Consumption and Implications for Parasite Dispersal

نویسندگان

چکیده

Black Carp (Mylopharyngodon piceus) has invaded the Mississippi River and is a potential threat to native mollusks. During prior diet research, we discovered that fluke Aspidogaster conchicola, mollusk parasite, occurs regularly in gastrointestinal tract of Carp. The remains fish intestines for extended periods after consumed its host. Flukes were found 33% wild examined, numbers ranged from 1 802, with no pattern evident across seasons capture. Treating flukes as indicators consumption, adjusted percent occurrence mollusks 26.6% 54.1%, indicating previously reported incidences bivalves (22.8%) gastropods (16.5%) are likely be underestimated. Based on occurrences Carp, larger (>791 mm) had significantly higher (42.6%) captured lentic habitats greater fluke-adjusted (87.5%). These diet-occurrence estimates, coupled presence gravid A. conchicola evidence their continued viability intestines, indicate these retain consumption evacuation tract. Consequently, disperse this parasite other

Leishmaniasis: A Review on Parasite, Vector and Reservoir Host

Leishmaniasis is a vector-borne disease affecting millions of people worldwide. The disease is caused by different species of Leishmania, and it is manifested by three major clinical forms namely cutaneous, muco-cutaneous and visceral leishmaniasis. This review is aimed to address briefly the parasite, the vector and the reservoir aspects in transmission of leishmaniasis in different regions of...

The evolution of parasite manipulation of host dispersal.

We investigate the evolution of manipulation of host dispersal behaviour by parasites using spatially explicit individual-based simulations. We find that when dispersal is local, parasites always gain from increasing their hosts' dispersal rate, although the evolutionary outcome is determined by the costs-to-benefits ratio. However, when dispersal can be non-local, we show that parasites invest...

Comparative host-parasite population structures: disentangling prospecting and dispersal in the black-legged kittiwake Rissa tridactyla.

Although much insight is to be gained through the comparison of the population genetic structures of parasites and hosts, there are, at present, few studies that take advantage of the information on vertebrate life histories available through the consideration of their parasites. Here, we examined the genetic structure of a colonial seabird, the black-legged kittiwake (Rissa tridactyla) using s...
