This mutation is also responsible for BZ resistance in other nematode species, including Caenorhabditis elegans, CylicCyclus nassatus and Cyathostomum
coronatum (Kwa et al., 1993; Kwa et al., 1994; Kwa et al., 1995; Pape et al., 1999; Samson- Himmelstjerna et al., 2001).
quadrispinulatum were determined by comparing these sequences with the previously published IGS rDNA sequences of Skrjabingylus chitwoodorum (AY295819), Cylicocyclus nassatus (AJ223348), and Cyathostomum
catinatum (AJ223339); the 18S rDNA sequences of Chabertia ovina (AJ920341) and Labiostrongylus bipapillosus (AJ920337); and the 28S rDNA sequences of Chabertia ovina (AM039733) and Labiostrongylus bipapillosus (AJ512837).
Among internal parasites, Oxyuris (O.) equi was recorded in maximum number of equines (n=40/450) followed by Parascaris (P.) equorum (n=36/450), Trypanosoma (T.) evansi (n=35/450), Strongylus (S.) vulgaris (n=12/450), Theileria (T.) equii, and/or Babesia (B.) caballi (n=11/450), Habronema (H.) muscae (n=05/450), Setaria (St) equina (n=04/450), Cyathostomum (C.) catinatum (n=04/450) and Cylicocyclus (Cy.) nassatus (n=02/450).
Note: There are 651 total entries for different diseases/conditions in 450 animals indicating that 44.7% of animals had more than one disease/condition [Gasterophilus nasalis (stomach), Habronema muscae (intestine), Setaria equina (liver), Cyathostomum catinatum (intestine), Cylococyclus nassatus (intestine) were recovered in autopsy of equines]
Small strongyles of genus Trichonema (Cyathostomum
) were identified in 47.86% of samples.
