Gastrointestinal nematode species diversity in Soay sheep kept in a natural environment without active parasite control
2016, Veterinary ParasitologyCitation Excerpt :Similar interactions driven by differential early stage larval challenge and the onset of protective immunity have been reported between T. colubriformis and Nematodirus spathiger (Dineen et al., 1977), H. contortus and T. axei (Reinecke et al., 1980), T. axei and T. circumcincta (Reinecke et al., 1982), and in cattle between Ostertagia ostertagi and Cooperia oncophora (Bairden et al., 1992). Not all such interactions operate to the detriment of the species involved, for example severity of N. battus infections may be increased by prior or simultaneous infection with coccidian protozoa (Christensen et al., 1987; Catchpole and Harris, 1989), or the establishment of Dictyocaulus viviparus may be enhanced by prior infections with O. ostertagi and C. oncophora (Kloosterman et al., 1990). Thus, regulatory influences of the large number of nematode parasite species on each other in the study Soay sheep flock could have contributed to the less clear pattern of sequential variation in predominance of individual species than is seen in intensively managed flocks.
Protostrongylid infection in meat sheep from Northwestern Spain: Prevalence and risk factors
2011, Veterinary ParasitologyCitation Excerpt :Taking into consideration that both lungworms have different transmission routes it is possible that positive interactions were immunologically mediated so that the presence of one species could facilitate the subsequent establishment of the other. Kloosterman et al. (1989, 1990) found positive interactions between lungworms in calves after previous infections with gastrointestinal nematodes and French et al. (2009) have detected that D. filaria infection generates similar immune response in ovine than Teladorsagia circumcincta infection in abomasal mucosa, so Dictyocaulus infection could provoke a lowered immunity response as described Kloosterman et al. (1989) for gastrointestinal nematodes that could facilitate sheep protostrongylid infection. However, further studies are necessary to elucidate this aspect.
