Helminths, hosts, and their microbiota: new avenues for managing gastrointestinal helminthiases in ruminants
2020
Evidence is emerging of complex interactions occurring between gastrointestinal (GI) parasites of ruminants and the resident gut flora, with likely implications for the pathophysiology of worm infection and disease. Similarly, recent data point toward the occurrence of a GI nematode (GIN)-specific microbiota, with potential roles in worm fundamental physiology and reproduction. Parasite-microbiota relationships might represent potential targets for the development of novel parasiticides.In this article, we review current knowledge of the role(s) that host- and helminth-associated microbiota play in ruminant host-parasite relationships, and outline potential avenues for the control of GIN of…
Ecological, morphological and genetic characterization of sympatric Haemonchus spp. parasites of domestic ruminants in Mauritania
1995
SUMMARYThe 4 species of ruminants (dromedary, zebu cattle, sheep and goat) in arid areas of Mauritania harboured Haemonchus spp. as the most frequent internal parasite. This was a rare situation where the 3 putative species, H. longistipes (dromedary), H. placet (zebu cattle) and H. contortus (sheep and goat) occurred sympatrically. The study was undertaken on hosts slaughtered at the Nouakchott abattoir, on the basis of monthly collection of worms. The environment was very unfavourable to H. placei and unfavourable to H. contortus, as intensity of infection remained low throughout the year, whereas infection in the dromedary was 10 to 20-fold higher. The survival strategies during the long…
