Coccidia of Canada geese(Branta canadensis) at Kortright Waterfowl Park, Guelph, Ontario, Canada, with description of Isospora anseris n.sp.

A survey of adult Canada geese, Branta canadensis, at Kortright Waterfowl Park in Guelph, Ontario, Canada, showed that 20% of the geese sampled passed small numbers of coccidial oocysts throughout the winter months (October 1975 to February 1976). Four species of coccidia, Eimeria hermani Farr, 1953, E. magnalabia Levine, 1951, E. truncata (Raillet and Lucet, 1891) Wasielewski, 1904, and Tyzzeria parvula (Kotlan, 1933) Klimes, 1963, were identified from the samples examined. A hitherto undescribed Isospora sp. was found in 5% of the fecal samples. It is named Isospora anseris and described as a new species. In the spring goslings were found to be passing E. hermani oocysts between the 8th and 13th day of hatching.

A New Species

Species in Lecanicillium are pathogens that parasitize various arthropods, nematodes, and other fungi. In an investigation of intestinal fungi associated with Marmota monax in China, three strains belonging to the genus Lecanicillium were isolated from the fresh fecal samples. Based on multi-locus phylogenetic analysis of the combined sequences (ITS, LSU, SSU, TEF, RPB1 and RPB2) and morphological characteristics, all species in Lecanicillium were well-separated. The three intestinal strains were assigned to a new species described as L. coprophilum in this paper. The new species differs morphologically from other Lecanicillium species by its dimensions of conidiogenous cells and conidia, the shape of conidia, dictyochlamydospores and swollen hyphae. The differences of L. coprophilum from other Lecanicillium species and closely related taxa are briefly discussed.

A New Species

Out of 77 of local meriz goats (Capra ibex), 29 (37.67%) were diagnosed as infected with coccidia. The infection percentage was 22.08% in kids less than six months of age as compared with older age (15.59%). A moderate diarrhea was the only clinical sign which was observed in three infected kids (3.9%). Six Eimeria (E.) species were diagnosed, they were E.alijevi, E.christenseni, E.caprovina, E.minasensis, E.megaembryonica, E.ninakohlyakimovae. E.megaembryonica was suggested to be a new species as it has a bigger embryonic mass which could be depended as a new parameter for coccidia classification. The germinal disk with two layers was very clear and observed in pre-sporulation Oocyst of most diagnosed species. The last three criteria are new in their mentioning. Also, Pot. Dichromate with 5% concentration is essential for follow-up of sporulation process to prevent of high bio - pollutants of fecal samples but without any effects upon biological features of isolated coccidia species.
