CONDITION FACTOR AND ECOLOGY OF ENDOHELMINTHS IN Metynnis lippincottianus FROM THE CURIAí­Å¡ RIVER, IN EASTERN AMAZON (BRAZIL)

Boletim do Instituto de Pesca, 2020
Fish are among the vertebrate groups most susceptible to parasitic infections due to environmental characteristics that can favor the development of parasites; also, position of the host in food web has been associated with the parasitism.

Helminth parasite infracommunities and dietary analysis of the rough-skinned newt, Taricha granulosa from south-eastern Vancouver Island, B.C.

, 2010
The rough-skinned newt, Taricha granulosa, is a common amphibian in the Pacific Northwest, but very little is known about its helminth parasites. This species typically overwinters on land and returns to breeding ponds in the spring and summer.

Host sexual dimorphism and parasite adaptation [PDF]

, 2012
In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response.

Variations of the parasitic infracommunity during the ontogeny of Chromis cyanea (Perciformes: Pomacentridae) in the North coast of Havana, Cuba

, 2015
The infracommunity of parasites of Chromis cyanea (Pisces: Pomacentridae) was studied along the ontogenetic development in the North coast of Havana, Cuba. The objectives were: a- to prove that the core species appears before the strange and stochastic species and they are responsible for the structure in the infracommunity, b- to determine if there is

First study on parasites of Hemibrycon surinamensis (Characidae), a host from the eastern Amazon region

Revista Brasileira de Parasitologia Veterinária
This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (
