Larval Ascaridoid Nematodes from Fishes near the Hawaiian Islands, with Comments on Pathgenicity Experiments

A total of 134 species of finfishes and 8 species of invertebrates, which were caught near the Hawaiian Islands over a 26-month period, were examined for larval nematodes. A total of 21,746 ascaridoid larvae were recovered. Larval nematodes of the genera Anisakis (two types), Hysterothylacium (three types), Raphidascaris (one type), and Terranova (two types) were identified. Descriptions and illustrations are provided for most larvae. A key is included. No anisakine larvae were found in the invertebrates. Inoculations of laboratory rats with various larvae demonstrated that at least Anisakis type II and Terranova type HA harm the host

El veneno y el mosquito: aspectos epistemológicos de la etiología y la profilaxis de la fiebre amarilla Poison and the mosquito: epistemological aspects of the etiology and prophylactics of yellow fever

En el II Congreso Médico Latinoamericano (Buenos Aires, 1904) se discutieron las estrategias que Argentina y Brasil delinearon para combatir la fiebre amarilla. El análisis de la controversia entre sanitaristas brasileños y argentinos en torno a los modelos explicativos y a las estrategias de profilaxis internacional de esa enfermedad, nos permite una comprensión epistemológica de la ruptura operada por la emergencia de la medicina de los vectores. Este capítulo de la historia de la medicina latinoamericana constituye una oportunidad privilegiada para analizar esa reorganización del saber que permitió integrar seres intermediarios vivos en el discurso médico y epidemiológico.<br>The strategies against yellow fever developed by Argentina and Brazil were discussed at the Second Medical Congress of Latin America which was held in Buenos Aires in 1904. The study of the controversy between physicians from Argentina and Brazil around the existing explanatory models of this illness and the international prophylactic strategies in use at the time enables an epistemological understanding of the breakthrough brought about by the emergence of the medicine of vectors. This chapter of Latin American medicine history constitutes a unique opportunity to analyze that reorganization of knowledge, which permitted the inclusion of intermediary living beings into the medical and epidemiological discourse
