“…The genus Marteilia has also been linked with either the haplosporidians because of the presence of membrane bounded granules similar to haplosporosomes (Comps 1970;Perkins 1976) or the myxosporeans due to the process of development characterised by pluricellularity and early individualisation of somatic elements (Desportes and Ginsburger-Vogel 1977;Desportes and Lom 1981). Corliss (1984), reviewing the kingdom Protista, considered the phylum Ascetospora, created by Sprague (1979) including Haplosporea and Paramyxea, as a polyphyletic assemblage requiring more study (Fig. 1a).…”

-Among mollusc pathogens, paramyxeans are an important group of protistan parasites belonging to the genera Marteilia and Marteilioides. Marteilia refringens and M. sydneyi are of particular concern given their potential impact on mollusc aquaculture world-wide. Aber disease and QX disease are currently listed by the OIE, the World Organisation for Animal Health. After more than thirty years of existence in the scientific literature, these organisms still pose questions and research challenges to investigators. This paper reviews current knowledge of the group and key references. The review was focused on taxonomy, epidemiology, pathology and potential control methods for these organisms in order to enhance understanding of paramyxean infection issues in mollusc aquaculture.Key words: Taxonomy / Epidemiology / Pathology / Diagnosis / Paramyxean parasites Résumé -Marteiliose des mollusques : une synthèse. Au nombre des agents pathogènes des mollusques, les paramyxéens, notamment les agents appartenant aux genres Marteilia et Marteilioides, sont des protistes parasites des plus importants. Marteilia refringens et M. sydneyi constituent un souci majeur compte tenu de leur impact potentiel sur la conchyliculture dans le monde. La maladie des Abers et la maladie du Queensland (QX) sont actuellement répertoriées par l'Office International des Epizooties. Après plus de trente années d'existence dans la littérature scientifique, ces organismes posent encore questions et défis aux investigateurs. Cet article fait l'état des connaissances sur le sujet en s'attachant plus particulièrement à la taxonomie, l'épidémiologie, la pathologie et les méthodes potentielles de contrôle de ces organismes dans l'optique d'une meilleure compréhension de la problématique des paramyxéens en conchyliculture.

“…Powdery scab has been implicated in increasing the susceptibility to late blight (Phytophthora infestans) (Dorojkin, 1936;Beregovoy, 1939;Schultz, 1952;Bonde, 1955), pink rot (Phytophthora erythroseptica) (Diriwächter & Parbery, 1991), dry rot (Fusarium caeruleum) (Foister et al, 1952) and rot caused by Colletotrichum atramentarium (Wade, 1949). CAUSAL ORGANISM While S. subterranea possesses features in common with fungi and protozoa (de Bary, 1858(de Bary, , 1859Martin, 1960;Karling, 1968;Fraser & Buczacki, 1983;Corliss, 1984;Barr, 1988), most mycologists now accept that S. subterranea, together with closely related species, should be regarded as a distinct class of fungi, the Plasmodiophoromycetes (Sparrow, 1958) within the division Myxomycota (fungi that do not produce hyphae but whose vegetative body is a naked holocarpic plasmodium). Braselton (1996), however, advocated erecting a separate phylum (division) for the plasmodiophorid fungi.…”

The chastity of amoebae: re-evaluating evidence for sex in amoeboid organisms

et al. 2011

Amoebae are generally assumed to be asexual. We argue that this view is a relict of early classification schemes that lumped all amoebae together inside the 'lower' protozoa, separated from the 'higher' plants, animals and fungi. This artificial classification allowed microbial eukaryotes, including amoebae, to be dismissed as primitive, and implied that the biological rules and theories developed for macroorganisms need not apply to microbes. Eukaryotic diversity is made up of 70þ lineages, most of which are microbial. Plants, animals and fungi are nested among these microbial lineages. Thus, theories on the prevalence and maintenance of sex developed for macro-organisms should in fact apply to microbial eukaryotes, though the theories may need to be refined and generalized (e.g. to account for the variation in sexual strategies and prevalence of facultative sex in natural populations of many microbial eukaryotes). We use a revised phylogenetic framework to assess evidence for sex in several amoeboid lineages that are traditionally considered asexual, and we interpret this evidence in light of theories on the evolution of sex developed for macro-organisms. We emphasize that the limited data available for many lineages coupled with natural variation in microbial life cycles overestimate the extent of asexuality. Mapping sexuality onto the eukaryotic tree of life demonstrates that the majority of amoeboid lineages are, contrary to popular belief, anciently sexual, and that most asexual groups have probably arisen recently and independently. Additionally, several unusual genomic traits are prevalent in amoeboid lineages, including cyclic polyploidy, which may serve as alternative mechanisms to minimize the deleterious effects of asexuality.
