Leishmaniose Visceral Americana: (Relatorio dos trabalhos realisados pela commissão encarregada do estudo da Leishmaniose Visceral Americana em 1937)

A Leishmania chagasi localisa-se principalmente nas cellulas reticulo-endotheliaaes dos tecidos. No sangue peripherico, o protozoario é visto com maior facilidade nos periodos iniciaes da infecção, quando pode ser observado livre, mais frequentemente no plasma de polynucleares e raramente no interior de macrophagos. Nas phases ulteriores, o parasito é raro no sangue peripherico e, quando encontrado, acha-se localisado no plasma de cellulas mononucleares. No interior dos leucocytos polynucleares apresentam as leishmanias signaes evidentes de degeneração, emquanto que nos macrophagos manteem o aspecto morphologico normal e as formas de multiplicação ocorrem com frequencia. Nos periodos agudos predominam os aspectos histo-pathologicos que traduzem intensa actividade do systema reticulo-endothelial e, nos periodos chronicos, a proliferação do tecido intesticial. O quadro hematologico é o de uma anemia sem signaes periphericos de regeneração. Os orgãos hematopoieticos demonstram signaes de perturbação funccional traduzida pelo exaggero da actividade que, entretanto, não leva á elaboração completa de globulos vermelhos, e á formação de granulocytos em número sufficiente. O quadro evolutivo da doença é o de uma anemia progressiva accompanhada de cachexia.

The Adolpho Lutz collection of Tabanidae: (Diptera): I. The described genera and species, condition of the collection, and selection of lectotypes

A study of the Adolpho Lutz Collection of Tabanidae at the Instituto Oswaldo Cruz and of additional Lutz material at the Instituto Butantan in São Paulo is reported. Of the ninety-four species of Tabanidae validly described by Lutz, type material of eighty-four was recognized, either holotypes, allotypes or syntypes. Lectotypes were selected from among syntype series or remaining specimens and all type material was labelled. Of the ten species of which no type material could be found, neotypes were designated in the case of two species, Erephosis nigricans and Erephosis pseudo-aurimaculata. Types of three species, Chrysops ecuadoriensis, Dichelacera salvadorensis and Esenbeckia nigricorpus are believed to have been in Hamburg and destroyed during the last war. Types of two species, Esenbeckia biscutellata and E. dubia, and additional type material of several others are believed to have been in Montevideo. A request for information about them remains unanswered. Types of the remaining three species, Dichelacera intermedia, Dichelacera laceriascia and Esenbeckia distinguenda could not be found, and it is believed that at least the type of the last species was accidentally destroyed. Three specific of subspecific names proposed by Lutz but palaced by others in synonymy have been revalidated, Acanthocera intermedia, Erephosis brevistria and Esenbeckia fenestrata. Generic placement of two names has been changed, Esenbeckia arcuata ricardoae to Proboscoides, and Selasoma giganteum to Stibasoma. Seven specific names proposed by Lutz appear to be synonyms of earlier names, as follows: Bombylopsis juxtaleonina Lutz and Castro, 1936 = B. leonina Lutz, 1909. Bombylopsis pseudoanalis Lutz, 1909 = B. erythronotata (Bigot, 1892). Esenbeckia fuscipennis var. flavescens Lutz, 1909 = Esenbeckia fuscipennis Wied., 1828. Fidena chrysopyga Lutz and Castro, 1936 = F. atra Lutz and Castro, 1936. Laphriomyia longipalpis Lutz and Castro, 1937 = L. mirabilis Lutz, 1911. Stibasoma semiflavum Lutz, 1915 = St. bicolor Bigot, 1892. Tabanus hesperus Lutz, 1912 = Chlorotabanus (Cryptolylus) innotescens (Walker, 1854). Four Lutz names appear to antedate names proposed by others, viz.: Diachlorus angustifrons Kröber, 1930 and D. ochraceus Kröb., 1928 not Macquart, 1850 = Diachlorus fuscistigma Lutz, 1913. Psalidia fairchildi Barretto, 1950 = dicladocera conspicua Lutz and Neiva, 1914. Fidena pseudo-fulvithorax Kröb., 1931 = Erephopsis flavicrinis Lutz, 1909. Esenbeckia lemniscata Enderlein, 1925 = Esenbeckia clari Lutz, 1909. Some comments on Lutz' system of classification are given together with notes on the genotypes and included species of his genera as revaled by his collection and notes.
