Morphogenesis and larval morphology were studied in the guinea pig and described herein. Host infection were achieved either by subcutaneous or by oral inoculation. The entsheathed infective larvae moult soon after penetration in the vertebrate host. Following subcutaneous inoculation, they reach the lungs very probably through the lymphatic vessels and the right heart at H8, and the stomach as soon as D2. However, a possible direct migration by the mesenteric lymphatic vessels and crossing of the digestive wall cannot be excluded as a few larvae were found in the peristomachal mesentery. Following ingestion, L3 larvae reached the stomach directly. 24 hours post-ingestion, they were localized deep inside the gastric mucosa crypts lumen. The same larval localization was observed at D3 after a subcutaneous inoculation. At D5, regardless of the inoculation route, larvae reached their definitive position, embedded in the gastric mucosa mucus lining, where they underwent the 3rd moulting (L3-L4) followed by the 4th moulting (L4-Ad) at D19. Eggs appeared at D28. Except for the inflammatory granuloma seen in the lungs and the mesentery from H24 to D3, the nematode induced no tissue lesion. The genus Paralibyostrongylus is one of the most primitive in the Libyostrongylinae-Cooperiinae line.

Both series had a high prevalence of Leishmania major infection. Lesions were small in November and large in May. Assuming the two collections were representative of typical years, it is inferred that the breeding season is between October and May: there is high winter mortality of animals born early in the breeding season, but high survival of their parents, and there is high mortality in summer of animals aged between 17 and around 20 months. Transmission in summer is, therefore, between old adults shortly before their death and young adults born in late winter or spring. Juvenile animals are not exposed to the infection.

Two factors significantly influenced the presence of snails in this zone : the water current velocity, and parasitic infection of the molluscs. In the presence of other factors (lack of food, the presence of the snail Physa acuta ), the L. truncatula were recovered more frequently in zones outside of the water and just beneath the water’s surface. Despite the modifications noted in snail distribution, Bulinus truncatus did not appear to be a competitor.
