“…Several reports have described the presence of double-stranded ribonucleic (dsRNA) viruses in di¡erent protozoa [2]. These dsRNA viruses have been found among some isolates of T. vaginalis [3,4], Giardia [5], Leishmania [6], and Eimeria [7]. These protozoa dsRNA viruses share several features.…”

Trichomonas vaginalis is a flagellated, parasitic protozoan that inhabits the urogenital tract of humans. Some isolates of T. vaginalis are infected with a double-stranded RNA (dsRNA) virus, which was described in the literature as homogeneous icosahedral viral particles with an isometric symmetry and 33 nm in diameter. This study examined in detail the viral particles in T. vaginalis isolate 347 and describes a heterogeneous population of viral particles. The different dsRNA viruses were only observed after a change in the technique. The sample was prepared by the negative staining carbon-film method directly onto freshly cleft mica. The detected viruses ranged in size from 33 to 200 nm. Among the shapes observed were filamentous, cylindrical, and spherical particles. These results show that T. vaginalis may be a reservoir for several different dsRNA viruses simultaneously.

“…Since then there have been several reports on the isolation and characterization of viruses in Giardia lamblia (Wang and Wang 1986b), Leishmania spp. (Tarr et al 1988), Eimeria stiedae (Revets et al 1989), and E. necatrix (Lee et al 1996). In addition, dsRNA segments indicative of viral infections have been found in the Houghton strain of E. necatrix and in several strains of E. maxima (Ellis and Revets 1990).…”

“…The genetic relatedness among the dsRNAs of some of these viruses have been studied with varying results (Wang and Wang 1986b;Revets et al 1989;Ellis and Revets 1990). Using dsRNA of E. stiedae as a probe in Northern hybridization studies, Revets et al (1989) found strong cross-reactivity between it and the dsRNA of G. lamblia.…”

Genetic relatedness was examined among putative viral double-stranded RNA (dsRNA) genomes of Eimeria acervilina, E. maxima, and E. necatrix using Northern hybridization. No cross-hybridization was found among these dsRNAs, revealing little sequence homology, if any. In addition, dsRNAs from eight E. acervulina strains collected from different localities in the United States were also examined for genetic relatedness. The putative viral dsRNAs from these eight strains, including the Guelph strain, hybridized with one another to varying degrees, indicating that they are related but divergent.

“…It is estimated that there are many thousands of Eimeria species [87]. Coccidiosis is primarily associated with enteric disease with few exceptions [88][89][90]. The avian coccidiosis can be subdivided into hemorrhagic and malabsorptive pathologies related to Eimeria brunetti, Eimeria necatrix and Eimeria tenella; or Eimeria acervulina, Eimeria maxima, Eimeria mitis and Eimeria praecox, respectively [91].…”

Apicomplexa is a eukaryotic phylum of intracellular parasites with more than 6000 species. Some of these single-celled parasites are important pathogens of livestock. At present, 128 genomes of phylum Apicomplexa have been reported in the GenBank database, of which 17 genomes belong to five genera that are pathogens of farm animals: Babesia, Theileria, Eimeria, Neospora and Sarcocystis. These 17 genomes are Babesia bigemina (five chromosomes), Babesia divergens (514 contigs) and Babesia bovis (four chromosomes and one apicoplast); Theileria parva (four chromosomes and one apicoplast), Theileria annulata (four chromosomes), Theileria orientalis (four chromosomes and one apicoplast) and Theileria equi (four chromosomes and one apicoplast); Eimeria brunetti (24,647 contigs), Eimeria necatrix (4667 contigs), Eimeria tenella (12,727 contigs), Eimeria acervulina (4947 contigs), Eimeria maxima (4570 contigs), Eimeria mitis (65,610 contigs) and Eimeria praecox (53,359 contigs); Neospora caninum (14 chromosomes); and Sarcocystis neurona strains SN1 (2862 contigs) and SN3 (3191 contigs). The study of these genomes allows us to understand their mechanisms of pathogenicity and identify genes that encode proteins as a possible vaccine antigen.
