Abstract Parasite infections are increasingly reported to change the microbiome of parasitized hosts, while parasites bring their own microbes what can be a multi-dimensional interaction. For instance, recent hypothesis suggests that microbial communities harboured by may play role in well-documented ability many manipulate host phenotype, and explain why degree which phenotype is altered varies among conspecific parasites. Here, we explored whether microbiomes both hosts associated with variation manipulation Using colour quantification methods applied digital images, investigated uninfected Transorchestia serrulata amphipods, as well amphipods infected Plagiorhynchus allisonae acanthocephalans dilepidid cestode. We then characterized bacteriota amphipod parasites, looking for correlations between bacterial taxa found large colours, weak support direct impact on hosts. Conversely, most interestingly, parasite’s was more strongly correlated potential amphipod-associated bacteria well. Some have synthesize pigments, propose they interact determination amphipods. This study provides correlational an association evolution host–parasite interactions generally.

For parasites with complex multi-host life cycles, the facultative truncation of cycle represents an adaptation to challenging conditions for transmission. However, why certain individuals are capable abbreviating their while other conspecifics not remains poorly understood. Here, we test whether conspecific trematodes that either follow normal three-host or skip final host by reproducing precociously (via progenesis) in intermediate differ composition microbiomes. Characterization bacterial communities based on sequencing V4 hypervariable region 16S SSU rRNA gene revealed same taxa occur both and progenetic individuals, independent identity temporal variation. all phyla recorded our study, two-thirds families, differed abundance between two morphs, some achieving higher morph others morph. Although evidence is purely correlative, results reveal a weak association microbiome differences intraspecific plasticity pathways. Advances functional genomics experimental manipulation will allow future tests significance these findings.
