Development of Graphidium strigosum (Nematoda, Haemonchidae) in its natural host, the rabbit (Oryctolagus cuniculus) and comparison with several Haemonchidae parasites of ruminants.

The morphogenesis (studied for the first time) and the chronology of the life cycle of Graphidium strigosum (Dujardin, 1845) were studied in detail in its natural host, Oryctolagus cuniculus. Naive rabbits were each infected per os with G. strigosum infective larvae (L3).

Moravecnema segonzaci gen. et sp. n. (Nematoda: Cystidicolidae) from Pachycara thermophilum (Zoarcidae), a deep-sea hydrothermal vent fish from the Mid-Atlantic Ridge.

The life cycle of Nematodiroides zembrae (Nematoda, Trichostrongylina) in the rabbit.

The morphogenesis and the chronology of the life cycle of Nematodiroides zembrae (Bernard, 1965), a parasite of Oryctolagus cuniculus from Spain, were studied in detail in its natural host. For each experiment a morphological description of the different stages of the life cycle is provided. The free-living larvae developed in eggs until infective stage.
