pseudostertagia bullosa (nematoda: trichostrongyloidea) in artiodactyl hosts from north america: redescription and comments on systematics. | a relationship for pseudostertagia bullosa within the trichostrongyloids has been enigmatic or unresolved. studies of the synlophe in males and females of p. bullosa revealed a tapering system anterior to the deirids and a pattern of parallel ridges extending to near the caudal extremity in both lateral and median fields. structurally, the synlophe differs considerably from that seen among the cooperiinae and exhibits homoplasy with respect to ridge systems among some ostertagiinae. other struct ... | 2005 | 15986613 |
a key for the identification of genera of the nematode family trichostrongylidae leiper, 1912. | the nematode family trichostrongylidae is divided into six subfamilies trichostrongylinae, libyostrongylinae, haemonchinae, cooperiinae, ostertagiinae and graphidiinae which are briefly reviewed. the key is based mainly on specimens examined by the authors and includes one genus in the trichostrongylinae, three genera in the libyostrongylinae, six in the haemonchinae, seven in the cooperiinae, 17 in the ostertagiinae and two in the graphidiinae. pseudostertagia, pararhabdonema, parostertagia, ob ... | 1982 | 7175163 |
