A revision of the taxonomy and nomenclature of the Eimeria spp. (Apicomplexa: Eimeriidae) from rodents in the Tribe Marmotini (Sciuridae)

Coccidia (Apicomplexa: Eimeriidae) Infecting Cricetid Rodents from Alaska, U.S.A., and Northeastern Siberia, Russia, and Description of a New Eimeria Species from Myodes rutilus, the Northern Red-Backed Vole

“…Here we list the 19 putative coccidia species we found in vole genera first, followed by the coccidia found in lemming hosts (see Table 1). For the new eimerian, we give a complete description following the format of Wilber et al (1998). For the coccidia that either have been recorded from a host genus or species before, or those that resemble strongly species described from other host genera, we provide only Dzerzhinskii and Svanbaev (1980) reported finding oocysts they called Eimeria argentata in a species of Alticola from the Altai Mountains in Kazakhstan, but did not describe the oocysts or provide any images.…”

“…Work by Hafner (1984) suggested that sciurids differentiated in the Pleistocene and that many may be able to harbor similar parasites. Based on these efforts, Wilber et al (1998) decided to use the ''morphological species concept'' to revise and summarize the coccidia of the Marmotini, the largest tribe within the Sciuridae. Recently this approach also has been used by others (e.g., Seville et al, 2005).…”

“…Symbiotype host specimens (Frey et al, 1992;Brooks, 1993), in which all oocyst species/forms were seen and identified here, are maintained in the University of Alaska Museum of the North (UAM) All measurements are presented in lm, and we used the abbreviations of Wilber et al (1998) as follows: length (L), width (W), micropyle (M), oocyst residuum (OR), polar granule (PG), Stieda body (SB), sub-Stieda body (SSB), sporocyst residuum (SR), sporozoite (SZ), and refractile body (RB).…”

Species of Coccidia (Apicomplexa: Eimeriidae) in Shrews From Alaska, U.S.A., and Northeastern Siberia, Russia, with Description of Two New Species

“…In general, little is known about host specificity in shrew coccidia. Studies on the coccidia in the mammalian order Rodentia by Hnida and Duszynski (1999b), Upton et al (1992), and Wilber et al (1998) suggest that coccidia specificity varies by host family. Wilber et al (1998) synonymized many of the Eimeria species previously described from Sciuridae (squirrels).…”

“…Skin, skull, skeleton, and tissues of the symbiotype host of both new eimerid species are preserved in the Mammal Division of the University of Alaska Museum (UAM), Fairbanks, Alaska. All measurements are in m (mean values and [ranges]), unless stated otherwise, and abbreviations follow those of Wilber et al (1998): length (L), width (W), micropyle (M), oocyst residuum (OR), polar granule (PG), Stieda body (SB), sub-Stieda body (SSB), para-Stieda body (PSB), sporocyst residuum (SR), and refractile body (RB), but we use SZ for sporozoites.…”
