[Fixation of various lectins at the surface of Crithidia luciliae].

Suspensions of Crithidia luciliae have been treated with 30 lectins: protozoans are agglutinated only by lectins inhibited with oses of structures I an II according to Mäkelä, and by lectins the site of fixation of which are unknown. The use of 5 lectins conjugated to fluorescein corroborate that lectins in congruity with group I and II, contrarily to those of group III, fasten upon the membrane and the flagella of Crithidia luciliae.

In vitro cultivation of Cryptosporidium parvum in the non-adherent human monocytic THP-1 cell line.

This study shows that the human monocytic cell line THP-1 supports the growth of C. parvum. Immunofluorescence controls showed that only scarce oocysts remained after infection and disappeared within the first 24 h of culture. A continuous asexual life cycle proceeded throughout the experiments, with at least 15-d cultures. This model provides a useful tool for studies on the biology of C. parvum in cells involved in its transport in immunocompromised host.

[A Gabonese case of paragonimiasis in a child].

We observed a case of lung infection with Paragonimus for a 4 year old child in Gabon. The treatment with bithionol was partially uneffective. Indeed, after the end of this treatment we observed hypereosinophilia, hyper IgG and X Rays pulmonary opacities but without eggs in stools of sputum.

[Helminths of the common fox (Vulpes vulpes L.) from the massif central (France) (author's transl)].

Sixty nine wild foxes originating from Auvergne for the period January 1977 to January 1978 have shown intestinal parasites in the proportion of 76,8 per cent. 59,4 per cent are invaded with Cestodes; 72,4 per cent with Nematodes and none with Trematodes. The list of the identified species is following: 1. Cestodes. A) Adults and fertile forms of: Mesocestoides litteratus in 27,5 per cent of the hosts; Taenia crassiceps in 15,9 p.c.; T. polyacantha in 27,5 p.c.; Echinococcus multilocularis in 7,2 p.c.; Amoebotaenia paradoxa in 4,3 p.c. B) Immature forms of : Taenia pisiformis in 2,89 p.c.; T. ovis in 1,44 p.c. 2. Nematodes. Uncinaria stenocephala in 68,1 per cent of the hosts; Ancylostoma caninum in 1,4 p.c.; Molineus patens in 1,4 p.c.; Oxyurid sp. in 1,4 p.c.; Toxocara canis in 27,5 p.c. and Toxascaris leonina in 33,3 p.c. The composition of the helminth fauna of the foxes in the center countries of France is not different of the European species from the same host, except Amoebotaenia paradoxa, Dilepidid cestode of birds, quite unusual from a carnivorus mammal.
