Coinfections of two or more parasites within one host are more of a rule than an exception in nature. Interactions between coinfecting parasites can greatly affect their abundance and prevalence. Characteristics of the host, such as genetic diversity, can also affect the infection dynamics of coinfecting parasites. Here we investigate for the first time the association of coinfection patterns of two marine apicomplexans, Rhytidocystis sp. and Selenidium pygospionis, with the genetic diversity of their host, the polychaete Pygospio elegans, from natural populations. Host genetic diversity was determined with seven microsatellite loci and summarized as allelic richness, inbreeding coefficient, and individual heterozygosity. We detected nonsignificant correlations between infection loads and both individual host heterozygosity and population genetic diversity. Prevalence and infection load of Rhytidocystis sp. were higher than that of S. pygospionis and both varied spatially. Coinfections were common and almost all hosts infected by S. pygospionis were also infected by Rhytidocystis sp.. Rhytidocystis sp. infection load was significantly higher in dual infections. Our results suggest that factors other than host genetic diversity might be more important in marine apicomplexan infection patterns and experimental approaches would be needed to further determine how interactions between the apicomplexans and their host influence infection.

Idiosyncratic effects of coinfection on the association between systemic pathogens and the gut microbiota of a wild rodent, the bank vole Myodes glareolus
Brila, Ilze; Lavrinienko, Anton; Tukalenko, Eugene; Kallio, Eva R.; Mappes, Tapio; Watts, Phillip C. (Wiley-Blackwell, 2023)The effects of systemic pathogens on gut microbiota of wild animals are poorly understood. Furthermore, coinfections are the norm in nature, yet most studies of pathogen–microbiota interactions focus on effects of single ... -
Spatiotemporal and gender-specific parasitism in two species of gobiid fish
Karvonen, Anssi; Lindström, Kai (John Wiley & Sons Ltd., 2018)Parasitism is considered a major selective force in natural host populations. Infections can decrease host condition and vigour, and potentially influence, for example, host population dynamics and behavior such as mate ... -
Interactions between two parasites of brown trout (Salmo trutta) : Consequences of preinfection
Gopko, Mikhail; Chowdhury, Motiur; Taskinen, Jouni (John Wiley & Sons Ltd., 2018)Preinfection by one parasitic species may facilitate or by contrast hamper the subsequent penetration and/or establishment of other parasites in a host. The biology of interacting species, timing of preinfection, and dosage ...
