Hedelmien ja marjojen kasvinsuojelututkimuksen tiedonvaihtoa Norjassa

Publikováno v: Kasvinsuojelulehti

Kirjoittajat osallistuivat syksyllä 2022 Oslossa kahteen tilaisuuteen, joissa kuultiin hedelmien ja marjojen kasvinsuojeluun ja laatuun liittyvää uutta tietoa. Pohjoismainen omenan laatuverkosto piti työpajan 7.-8.11.2022. Suomesta mukana oli sei

Multispecies coinfections and presence of antibiotics shape resistance and fitness costs in a pathogenic bacterium

Autor: Ashrafi, Roghaieh, Bruneaux, Matthieu, Sundberg, Lotta‐Riina, Hoikkala, Ville, Karvonen, Anssi

Increasing antimicrobial resistance (AMR) poses a challenge for treatment of bacterial diseases. In real life, bacterial infections are typically embedded within complex multispecies communities and influenced by the environment, which can shape cost

Genetic variation in resistance against parasite infections is a predominant feature in host–parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally poorly known. We explored wh

Host Developmental Stage Effects on Parasite Resistance and Tolerance

Autor: Ines Klemme, Paul Vincent Debes, Craig Robert Primmer, Laura Sofia Härkönen, Jaakko Erkinaro, Pekka Hyvärinen, Anssi Karvonen

Publikováno v: The American naturalist. 200(5)

Hosts can defend themselves against parasites either by preventing or limiting infections (resistance) or by limiting parasite-induced damage (tolerance). However, it remains underexplored how these defense types vary over host development with shift

Glochidial infection by the endangered Margaritifera margaritifera (Mollusca) increased survival of salmonid host (Pisces) during experimental Flavobacterium disease outbreak

Publikováno v: Parasitology Research

Co-infections are common in host-parasite interactions, but studies about their impact on the virulence of parasites/diseases are still scarce. The present study compared mortality induced by a fatal bacterial pathogen, Flavobacterium columnare betwe

Salmon lice in the Pacific Ocean show evidence of evolved resistance to parasiticide treatment

Autor: Sean C. Godwin, Andrew W. Bateman, Anna Kuparinen, Rick Johnson, John Powell, Kelly Speck, Jeffrey A. Hutchings

Publikováno v: Scientific Reports

Parasitic salmon lice (Lepeophtheirus salmonis) threaten the economic and ecological sustainability of salmon farming, and their evolved resistance to treatment with emamectin benzoate (EMB) has been a major problem for salmon farming in the Atlantic

Sequence variation and regulatory variation in acetylcholinesterase genes contribute to insecticide resistance in different populations of Leptinotarsa decemlineata

Ecology and Evolution, Vol 11, Iss 22, Pp 15995-16005 (2021)

Although insect herbivores are known to evolve resistance to insecticides through multiple genetic mechanisms, resistance in individual species has been assumed to follow the same mechanism. While both mutations in the target site insensitivity and i

Negative associations between parasite avoidance, resistance and tolerance predict host health in salmonid fish populations

Autor: Anssi Karvonen, Pekka Hyvärinen, Ines Klemme

Publikováno v: Proc Biol Sci

Genetic variation in defence against parasite infections is fundamental for host–parasite evolution. The overall level of defence of a host individual or population includes mechanisms that reduce parasite exposure (avoidance), establishment (resis
