Future water temperature changes may have a profound impact on fish-parasite interactions. However, while the effect of fish, and particularly salmonids, is well-understood, its combined effects with parasitic exposure are not. Here, we use multi-stage experimental approach to explore increased temperatures consistent persistent climate change-induced warming extreme thermal fluctuations from h...

The Arctic is rapidly warming and host-parasite relationships may be modified by such environmental changes. Here, I showed that the average winter temperature in Svalbard, Arctic Norway, explained almost 90% of the average prevalence of ticks in an Arctic seabird, the Brünnich's guillemot Uria lomvia. An increase of 1°C in the average winter temperature at the nesting colony site was associate...

  Two hundred forty seven species of parasites from Iranian freshwater fishes are presented in this synopsis. The parasites were recorded from infestations in fish from different parts of the country and summarized according to host species, organs were the parasite infestations occurred, province, faunal region and reference numbers. The following aspects of parasite infestations were also dis...

the possible existence of equine piroplasmosis was investigated in the province of quezon, philippines. blood samples of 269 horses from selected municipalities of quezon province were gathered. parasitological test namely blood parasite examination was employed and the test yielded negative results for the presence of the parasite. similarly, polymerase chain reaction assay was performed using...

Numerous methods exist for molecular-based detection of Nosema ceranae. Here we determine location of parasite loads, the optimal tissue for pathogen detection, and the likely sources of variability among assays. Bee washes and head/thorax samples revealed substantial N. ceranae loads (2.67×10(4)±1.12×10(4) and 1.83×10(4)±4.14×10(3)). Midgut samples carried the highest parasite loads (3.42×10(6...

The Phylum Protozoa brings together several organisms evolutionarily different that may act as ecto or endoparasites of fishes over the world being responsible for diseases, which, in turn, may lead to economical and social impacts in different countries. Apart from the recent advances for the diagnosis of fish diseases in Brazil, little is known on the protozoan parasites and their relationshi...

Although research into the ecology and impacts of invasive species is prevalent, there are knowledge gaps relating to role in parasite transmission. This work synthesises host–parasite interactions impacts, using marine bivalves as a model group, consider how global movement shellfish consignments for aquaculture purposes facilitates unintentional transfer invasives. We discuss can act both hos...

The fishery of bony fishes has an economic important in southern part of Caspian Sea ,but there are few reports about the pathogens of them in this area .Eustrongylides excisus , a parasite (Nematoda: Dioctophymidae) can damage the muscles of bony fishes . So, consumers avoid to buy the infected fish. Hence , the parasite can cause economic loss.In order to determine the occurance and intensity...
