Parasites of the flatfish Paralichthys adspersus (Steindachner, 1867) (Pleuronectiformes) from northern Chile

Three species of protistan and 22 species of metazoan parasites were obtained from a sample of 179 flatfish, (Paralichthys adspersus) taken-off Antofagasta, northern Chile. Prevalence of infection of seven parasites (Protista: 1, Copepoda: 2, Digenea: 1, Acantocephala: 1, Nematoda: 2) was significantly and positively correlated with host size. Host's sex do not seem to affect prevalence of infection, except for Nybelinia surmenicola, Capillaria sp. and Anisakis sp. (prevalence of infection significantly greater in males than females) and Philometra sp. (prevalence higher in females). Mean abundance is correlated with size in nine species (Protista: 1, Copepoda: 2, Digenea: 3, Acantocephala: 1, Nematoda: 2). Host's sex do not affect mean abundance, except for Cainocreadium sp. and Philometra sp.(mean abundance higher in females) and Nybelinia surmenicola, Capillaria sp. and Anisakis sp. (mean abundance higher in males).

Studies on Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 (Nematoda: Camallanidae), with new host records and new morphological data on the larval stages

Larval stages and adults of Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 are described from naturally infected Paralonchurus brasiliensis (Steindachner) (Sciaenidae) from the coast of the State of Rio de Janeiro, Brazil. The translucent first-stage larvae have a denticulate process at the anterior end, no buccal capsule or esophagus undifferentiated into anterior muscular and posterior glandular parts and an elongate tail; third-stage larvae have a tail with three terminal projections, a buccal capsule divided into an anterior portion with 12-20 ridges running to the left and a posterior smooth portion, and an esophagus with muscular and glandular regions. Fourth-stage larvae exhibit a buccal capsule lacking a distinct basal ring with ridges running to the right and a tail with two terminal processes, as in adults. New host records are reported and their role in its life-cycle are discussed.

Dieu, vingt-six portraits bibliques

Vingt-six portraits par vingt-six exégètes. Tel est le défi proposé et assumé pour un parcours surprenant de lectures et d'interprétations multiples d'un Dieu unique et en même temps complexe. Quelle cohérence entre le Dieu fracassant de l'Exode et le Dieu crucifié de l'apôtre Paul ? Quelle continuité entre le Dieu de Gédéon et celui de Jésus : " Mon Dieu, mon Dieu, pourquoi m'as-tu abandonné ? " (Mc 15,34) ? Le Dieu de l'entrée en Canaan ressemble-t-il vraiment à l'Agneau immolé de l'Apocalypse ? Mais déjà, au sein de la Bible hébraïque, les trompettes de Jéricho côtoient le Serviteur souffrant d'Isaïe. Comment comprendre aujourd'hui cette diversité de la présence de Dieu dans la Bible, si ce n'est par la diversité des regards d'exégètes dont la lecture croisée des textes bibliques nous invite à renouveler notre compréhension de Dieu ?
