[Can arboviruses from seabird colonies in Brittany infect man?].

Four tick-borne arboviruses circulate heavily and permanently among the seabirds colonies located along the coasts of Brittany: Soldado, Zaliv Terpeniya, Avalon and a member of Tyuleniy subgroup of flaviviruses. In order to appreciate the ability of these viruses to infect man, the authors studied for antibodies the sera of farmers living in South-Finistere, in the vicinity of Cape Sizun seabirds reserve. Antibodies were actually found on 14 of 474 farmers, or 3.0 per cent, substantiating the reality of infection by these agents. The possible mechanisms of the contamination and the eventual pathologic results of these viral infections are discussed.

Studies on Bunyaviridae including Zaliv Terpeniya virus isolated from Ixodes uriae ticks (Acarina: Ixodidae) in Brittany, France.

Three viruses were isolated from ticks parasitizing nesting seabirds on Cape Sizun, Brittany, France, during the spring of 1979: Soldado like virus (Bunyaviridae, Nairovirus genus) from Ornithodoros (Alectorobius) maritimus (Argasidae), Zaliv Terpeniya (ZT) virus (Bunyaviridae, Uukuvirus genus) from Ixodes (Ceratixodes) uriae (Ixodidae) parasitizing chicks of the kittiwake (Rissa tridactyla), and a virus of the Sakhalin group from I. (C.) uriae. Certain virological and ultrastructural properties of ZT virus were studied and the antigenic relationships between th French isolate and other UUK serogroup viruses from I. (C.) uriae were analyzed in the complement fixation and immune diffusion tests. Cape Sizun is notable for the unusual presence of both argasied (Ornithodoros) and ixodid (Ixodes) ticks infesting seabirds in adjacent niches in a single locality, where they are infected by different viruses.

[Serum IgE values in human scabies: study of 79 cases (author's transl)].

The authors studied seric IgE levels in 79 patients with scabies: 48 p. 100 had significant elevated concentration of IgE (greater than 300 U. I./ml) (p less than 0,001). This is the fact of scabies infestation and is not the result of internal parasitic infestation, associated illnesses or atopic disease. There is a statistically significant correlation between high IgE levels and degree of extension (p less than 0,1) and, overall, eczematization (or) and superinfection (p less than 0,001).

[Human trichostrongyloidosis: case report and microscopic difficulties to identify ankylostomidae eggs].

We present the case of a 53 year old woman living in a rural area and which suffered from gastric pain and high blood eosinophil polymorphonuclear counts for several years. The parasitological stool examination showed Trichostrongylus sp. larvae and eggs. Clinical and biological signs resolved after 2 courses of treatment with albendazole. We also report the microscopic difficulties to identify Ankylostomidae eggs.

[2 Breton cases of autochthonous malaria, in reality the first French cases of "airport malaria"].

Two cases of Plasmodium falciparum malaria encountered in Finistere in 1969 are regularly referred to in the literature as infections acquired in Brittany. In view of the extreme rarity of such an occurrence, it was decided to reexamine the data and consider in detail the biological and epidemiological factors for and against the possibility of infection occurring in Brittany.
