| molecular characterisation of the microsporidia of the amphipod gammarus duebeni across its natural range revealed hidden diversity, wide-ranging prevalence and potential for co-evolution. | microsporidia comprise an unusual group of intracellular, eukaryotic parasites that exhibit ubiquitous distribution throughout the animal kingdom. we analysed the small subunit ribosomal gene (ssurdna) using pcr and sequencing and screened 894 gammarus duebeni (crustacea, amphipoda) specimens from 35 european marine and freshwater populations. we discovered considerable hidden microsporidian diversity. blast searches, sequence analysis and phylogenetic analysis revealed intraspecific sequence va ... | 2010 | 20601176 |
| microsporidia parasites disrupt the responses to cadmium exposure in a gammarid. | microsporidia parasites are commonly found in amphipods, where they are often asymptomatic, vertically-transmitted and have several effects on host sexuality and behaviour. as amphipods are often used as models in ecotoxicological studies, we investigated the effect of microsporidian infections on energy reserves and defence capacities of gammarus roeseli under cadmium stress. only females were infected by two microsporidia parasites: dictyocoela roeselum or dictyocoela muelleri. in physiologica ... | 2012 | 22035920 |
