“…Scarce or no differences were found between the nodular Eimeria subepithelialis and Goussia balatonica; similarly, two epicellular species (Goussia pannonica and Goussia janae) were found to be closely related. Lovy and Friend (2015) who described G. ameliae, an epicellular coccidium infecting a clupeid fish, concluded that sequences of this species show a great similarity to sequences of epicellular Goussia spp. (G. koertingi, G. pannonica and G. janae) of cyprinid fishes.…”

“…Only a few representatives of fish Goussia (G. janae, G. metchnikovi, G. kuehae, G. ameliae) and three species from tadpoles (G. neglecta, G. noelleri and an unnamed Goussia sp) have yet been included in molecular phylogenies of the coccidia (Jirku et al, 2002, 2009, Gibson-Kueh et al 2011a,b, Székely et al 2013, Lovy and Friend, 2015, in spite of the fact that such Apicomplexan protozoans are prevalent in both freshwater and marine fishes (recently reviewed by Molnár, 2005, 2006and by Steinhagen et Davies, 2008. Although these sequences are dissimilar from those previously described from piscine Eimeria, sampling has not yet sufficed to determine whether other types of Goussia belong to this same lineage.…”

“…Genetic data provide a means to evaluate which, if any, of these developmental characteristics demarcate groups of parasites sharing specific evolutionary histories. A few studies have begun to evaluate phylogeny using 18S rDNA (Molnar et al, 2012;Lovy and Friend, 2015;Bartosová-Sojková et al, 2015) and one has used a transcriptomic approach to evaluate the position of an epicellular species of Goussia using several single-copy housekeeping genes (Dogga et al, 2015). The latter found that genes of Goussia janae typically were inferred as basal to the sarcocystids or as basal to the whole eimeriorinid clade; less frequently, a gene from this epicellular parasite was placed at the base of the Eimeriid subclade or as within the sarcocystid subclade (Dogga et al, 2015).…”

Fish are the oldest and most diverse group of vertebrates; it therefore stands to reason that fish may have been the original hosts for many types of extant vertebrate parasites. Here, we sought to determine whether coccidian parasites of fish are especially diverse. We therefore sampled such parasites from thirty-nine species of fish and tested phylogenetic hypotheses concerning their relationships, using 18S rDNA. We found compelling phylogenetic support for distinctions among at least four lineages of piscine parasites presently ascribed to the genus Goussia. Some, but not all parasites attributed to Eimeria were confirmed as such. Major taxonomic revisions are likely justified for these parasites of fish, which appear to have given rise to each of the major lineages of coccidian parasites that subsequently proliferated in terrestrial vertebrates, including those such as Toxoplasma gondii that form tissue cysts in intermediate hosts.

Wild bluegill, Lepomis macrochirus Rafinesque, succumb to seasonal mortality in the early spring during cool water temperatures, shown previously to be related to bacteraemia caused by a psychrotrophic bacterium, Pseudomonas mandelii. In the study herein, intestinal coccidiosis in wild bluegill had seasonal prevalence causing heavy intestinal infections and sloughing of intestinal epithelium occurring in late winter/early spring. Infections were predominantly related to two different species, Goussia washuti n. sp., an epicellular coccidium, and a coccidium closely resembling Goussia desseri Molnár 1996, previously only described in percid fish in Europe. In 2019, co‐infections of bacteraemia and intestinal coccidiosis occurred in bluegills. Evaluating coccidium infection intensity by fresh parasite examination and histology, an association was observed in which fish with moderate‐to‐heavy intestinal coccidiosis were 8–12 times more likely to have bacteraemia compared to fish with no or light coccidiosis. The association of these co‐infections suggests that intestinal coccidiosis could contribute to seasonal bacterial epizootics of wild bluegill.

“…In the 18S rDNA-based phylogeny, some piscine coccidians (e.g. G. janae, G. ameliae, G. pannonica, G. szekelyi) form basal lineages of the species-rich eimeriorinid clade, or of its sarcocystid subclade, which encompass economically important parasites of both homeothermic and poikilothermic vertebrate hosts (Bartošová-Sojková et al 2015;Jirků et al 2002;Lovy and Friend 2015;Molnár et al 2012;Whipps et al 2012).…”

To fill the knowledge gap on the biology of the fish coccidian Goussia janae, RNA extracted from exogenously sporulated oocysts was sequenced. Analysis by Trinity and Trinotate pipelines showed that 84.6% of assembled transcripts share the highest similarity with Toxoplasma gondii and Neospora caninum. Phylogenetic and interpretive analyses from RNA-seq data provide novel insight into the metabolic capabilities, composition of the invasive machinery and the phylogenetic relationships of this parasite of cold-blooded vertebrates with other coccidians. This allows re-evaluation of the phylogenetic position of G. janae and sheds light on the emergence of the highly successful obligatory intracellularity of apicomplexan parasites. G. janae possesses a partial glideosome and along with it, the metabolic capabilities and adaptions of G. janae might provide cues as to how apicomplexans adjusted to extra-or intra-cytoplasmic niches and also to become obligate intracellular parasites. Unlike the similarly localized epicellular Cryptosporidium spp., G. janae lacks the feeder organelle necessary for directly scavenging nutrients from the host. Transcriptome analysis indicates that G. janae possesses metabolic capabilities comparable to T. gondii. Additionally, this enteric coccidium might also access host cell nutrients given the presence of a recently identified gene encoding the molecular sieve at the parasitophorous vacuole membrane.
