comparison of european systemic piscine and amphibian iridoviruses with epizootic haematopoietic necrosis virus and frog virus 3.iridovirus-like agents isolated from systemic infected fish (silurus glanis, sfir; ictalurus melas, cfir i, cfir ii, cfir iii) and from frogs (rana esculenta, reir) in europe, epizootic haematopoietic necrosis virus (ehnv) isolated in australia from redfin perch (perca fluviatilis), and frog virus 3 (fv 3) isolated from frogs (rana pipiens) in the usa were investigated by electron microscopy, polypeptide composition, immunofluorescence, restriction endonuclease digestion, southern-blot hybridiza ...19989719770
the benefits of coinfection: trematodes alter disease outcomes associated with virus infection.1.coinfections are increasingly recognized as important drivers of disease dynamics. consequently, greater emphasis has been placed on integrating principles from community ecology with disease ecology to understand within-host interactions among parasites. using larval amphibians and two amphibian parasites (ranaviruses and the trematode echinoparyphium sp.), we examined the influence of coinfection on disease outcomes. 2.our first objective was to examine how priority effects (the timing and s ...201728317105
environmental dependency of amphibian-ranavirus genotypic interactions: evolutionary perspectives on infectious diseases.the context-dependent investigations of host-pathogen genotypic interactions, where environmental factors are explicitly incorporated, allow the assessment of both coevolutionary history and contemporary ecological influences. such a functional explanatory framework is particularly valuable for describing mortality trends and identifying drivers of disease risk more accurately. using two common north american frog species (lithobates pipiens and lithobates sylvaticus) and three strains of frog v ...201425469155
inactivation of viruses infecting ectothermic animals by amphibian and piscine antimicrobial peptides.the ability of five purified amphibian antimicrobial peptides (dermaseptin-1, temporin a, magainin i, and ii, pgla), crude peptide fractions isolated from the skin of rana pipiens and r. catesbeiana, and four antimicrobial peptides (amps) from hybrid striped bass (piscidin-1n, -1h, -2, and -3) were examined for their ability to reduce the infectivity of channel catfish virus (ccv) and frog virus 3 (fv3). all compounds, with the exception of magainin i, markedly reduced the infectivity of ccv. in ...200415193922
inactivation of frog virus 3 and channel catfish virus by esculentin-2p and ranatuerin-2p, two antimicrobial peptides isolated from frog skin.while it is clear that some amphibian populations have recently experienced precipitous declines, the causes of those die-offs are complex and likely involve multiple variables. one theory suggests that environmental factors may trigger events that result in depressed immune function and increased susceptibility to infectious disease. here we examine one aspect of innate immunity in amphibians and show that esculentin-2p (e2p) and ranatuerin-2p (r2p), two antimicrobial peptides isolated from ran ...200111601906
new disease records for hatchery-reared sturgeon. i. expansion of frog virus 3 host range into scaphirhynchus albus.in 2009, juvenile pallid sturgeon scaphirhynchus albus, reared at the blind pony state fish hatchery (missouri, usa) to replenish dwindling wild stocks, experienced mass mortality. histological examination revealed extensive necrosis of the haematopoietic tissues, and a virus was isolated from affected organs in cell culture and then observed by electron microscopy. experimental infection studies revealed that the virus is highly pathogenic to juvenile pallid sturgeon, one of several species of ...201425320034
