Ensaios de micologia contribuição para o conhecimento das Esporotricoses

The author describes the forms found in material obtained from a human lesion localized in the mouth. The patient was a farmer and the diagnosis unknown. The author found yeast forms, some germinating, resembling those found in the mycosis of LUTZ. It was Sporotricosis and only once, in 96 cases, has the author found these fungous forms in the suspected material. The cultures in Sabouraud glucose and in many other media were positive for Sporotrichum, resembling that described by BENEDEK in 1926 (variety?) principally by the reddish colour of some cultures. The author thinks there is, perhaps, a mutation influenced by the surroundings and the light in certain cultures and that the dark pigment is the dominant one. He considers that the pigment will not do for the differentiation of species and that it is, really, Sporotrichum Schencki-Beurmanni. The author calls attention to the question of diagnosis and studies separately, each of the elements in which his opinion is based, finding that only a macro and microscopic study of the cultures decides the question.

Contribuição para o conhecimento das doenças do grupo "Tifo Exantemático" do Brasil: (Tifo Exantemático Neotrópico)

O A. recapitula os dados já conhecidos sôbre a filtrabilidade de muitas Rickettsias e sôbre o que êle chama o ciclo evolutivo das mesmas, citando os trabalhos de S. B. Dulky e E. Gordon sôbre a Coxiella papilliae e a observação de A. Donatien e F. Lestoquard bem como os de P. Giraud. Refere-se à filtrabilidade do agente da febre "Q". Reporta-se depois aos trabalhos de Mme. Ruth Rein Gutfreund sôbre os achados de Rickettsia prowazedi em animais domésticos na Etiópia e a transmissão dos mesmos pelos carrapatos, dizendo que isto confirma suas próprias idéias, de há muito emitidas, de que não há no grupo tifo exantemático, de regra, especificidade estrita para os transmissores, não podendo êste carácter servir de base para classificações racionais. Descreve um caso clínico, mostrando a dificuldade de diagnóstico cofundido com a febre tifóide, mesmo com longa prática do exame na doença e que só a inoculação em animais sensíveis - aqui os cobaios - pode decidir a questão. Estuda depois dois surtos epidêmicos de tifo exantemático neotrópico - em 1950 em Carmópolis (Minas Gerais); outro em 1956, Mucuri (Bahia). Em ambos, a percentagem de mortes dos casos graves, não tratados, foi elevada e a terapêutica pelos antibióticos, principalmente a Cloromicetina e Terramicina foi brilhante. Nestes dois surtos epidêmicos com já se vira em 1941 (4 casos na mesma residência) e 1948 (6 casos na mesma moradia), apuraram-se 2 e 3 casos da doença na mesma casa. As reações de Fixação de Complemento (R.F.C.), Weil-Feliz (W.F.) e Widal - confirmam o diagnóstico de tifo exantemático neotrópico.

Contribuição ao conhecimento do gênero Archytas jaennicke, 1867 (Diptera, Tachinidae)

In this paper three species of genus Archytas are studied, the type species A. diaphana (Fabr.), A. shannoni sp. n. and A. willistoni Curran. The definitions of the species are based on the characters of the male and females genitalia.

Segunda contribuição ao conhecimento do gênero Archytas Jaennecke, 1867: (Diptera, Tachinidade)

In the present paper four species of genus Archytas Jaennecke, 1867, are studied and figured in detail: Archytas incertus Macq. (= Pseudoarchytas brasiliensis Towns), Archytas marmoratus Towns. (= Archytas pilifrons Sch.) and Archytas chilensis Curran. A new species Archytas travassosi is described from Angra dos Reis, Brazil. The material studied is deposited in the following collections: Instituto Oswaldo Cruz, Escola Nacional de Veterinária, Departamento de Zoologia da Secretaria de Agricultura do Estado de São Paulo and Departamento de Defesa Sanitária Vegetal, Brasil.

Terceira contribuicäo ao conhecimento do gênero Archytas Jaennicke, 1867: (Diptera, Tachinidae)

Twelve species of the genus Archytas Jennicke, 1867, eight of which described as new are studied and figured in detail. Definitions of the species are based mainly on characters of male genitalia. The male genital characters are the most significant for separation of the species and most demonstrative of their affinities. By examining a long series of species of this genus we came to the conclusion that the presence of one pair of median marginal bristles on the third abdominal tergite seems to be characteristic of the genus. This caracter apparently so important, is not however considered fundamental. The most significant example is found in Archytas lenkoi sp. n. and Archytas vexor Curran, 1928. In A. lenkoi we can find one or two pairs or thay may, less frquently, be absent. In A. vexor these bristles are lacking. The shape of the male copulatory apparatus of Jurinia nitidiventris Curran, 1928 refered to by CURRAN in his "Revision of Archytas", is not characteristic of any species of the group and so, is not considered in this paper. To help in the identification, the species studied here are divided into groups. The analis group" includes: A. apicifer (Walker, 1894), A. californiae (Walker, 1856), A. nivalis Curran, 1928, a. giacomellii (Blanchard, 1941), A. basifulvus (Walker, 1849), A. incasanus Townsend, 1912 and A. cirphis Curran, 1927. The identification of members of these group is extremely difficult owing both to their similarity in colour pattern and to their variability. They all have black testaceous or dark brown abdomen, the last segment pale or brownish pollinose; second segment without bristles; third with a pair of strong marginals, fourth and fifth with two rows of discals on apical third. The final determination often rests upon the structure of the male copulatory apparatus. Fortunately in this group, many of the forcipes superiores and palpi genitalium are strikingly different from one another. The "zikani group" includes: A. zikani sp. n., A seabrai sp. n., A. duckei sp. n. and A. vernalis Curran, 1928. This group may be characterized as follows: forcipes interiores absent; forcipes superiores strongly chitinized an dilated at anex. Within this group, the forcipes of. A. seabrai sp. n. do not present an aberrant form. The "dissimilis group" will be studied in forthcoming papers. The limits of the genus Archyta Jaen. are not as yet sharply difined, the evaluation of the significance of each character used in the definition remaining as most difficult problem. The distinction between Archytas and other related genera is very difficult, chiefly because it is based on variable characters. In this paper we place the genera Parafabricia Towsend, 1931, Itachytas Blanchard, 1940, Archynemochaeta Blanchard, 1941, Proarchytoides Blanchard, 1941 and Archytodejeania Blanchard, 1941 in the synonymy of Archytas Jaen. The detailed examination of the characters used in their definition, proved them to be fundamentally proposed on basis of chaetotasy, these characters alone being precarious, because of the considerabel intraspecifical variation. The type of the new species are in the Oswaldo Cruz Institute collection. Rio de Janeiro, Brazil, and paratypes in the collections of the followings institutions: Departamento de Zoologia da Secretaria de Agricultura do Estado de São Paulo; Instituto de Ecologia e Experimemtação Agrícolas; Departamento de Defesa Sanitária Vegetal; Campos Seabra collection; and Barbiellini collection.

Contribuição ao conhecimento da tribu Ormiini: I: gênero Ormia robineau-desvoidy 1830 (Diptera, Tachinidae)

The author redescribes two species of the genus Ormia: Ormia bilimekii Brauer et Bergenstamm, 1889 and ormia lineifrons Sabrosky, 1953, Brasil. Two new species, Ormia rachoui sp. n. from Corcovado, Estado da Guanabara and Ormia lopesi sp. n. from Angra dos Reis, Estado do Rio de Janeiro, Brasil, are also described.

Primeira contribuição ao conhecimento da tribu Cuphoceratini: (Diptera, Tachinidae)

The author studies 10 species of the Tribu Cuphoceratini, belonging to the genera Ccrpecrypta Townsend, 1908, Cyanopsis Townsend, 1917, Spanipalpus Townsend, 1931, Neocuphocera Townsend, 1927, Beskiocephala Townsend, 1916 and Deopalpus Townsend, 1908. Eight species are identified with previously described species and two species are considered new to science: Neocuphocera aurifacies sp. n. and Deopalpus reinhardi sp. n. The characteristics of the new species are chiefly founded in the male genitalia. Generic definitions are based on the following characters: presence or absence of ocellar bristles, shape and relative length of antennal articles and arrangement of the head bristles in both sexes. The material is located in the Institute Oswaldo Cruz collections, Guanabara, Brazil.

Quarta contribuição ao conhecimento do gênero Archytas Jaennicke, 1867: (Diptera, Tachinidae)

The author studies 5 species of Archytas Jaennicke, 1867, belonging to the "dissimilis group": A. seminigra (Wiedemann, 1830) and four species which are considered as new. The species of this group may be characterized as follow: Species of short body, exceptionally large ones. Abdomen yellowish, with a median blackish V-shapedspot. Second antennal segment with 2/3 length of third. Parafacialia with blackish hairs. Propleura pilose. Post alar wall with few hairs. The following key facilitates the identification of the species: 1. Third article of antennae, strongly convex in the anterior margin (fig. 10); posterior margin straight. Parafacialia with a facio-orbital bristle well differentiated . . . . A. arnaudi sp. n. — Third article of antennae not so convex in the anterior margin; facio-orbital bristle absent, if present not well differentiated [...] 2; 2. Parafrontalia with golden polen [...] 3; — Parafrontalia brownish to shining black with few polen . . . 4; 3. Forcipes superiores slender and sub-truncate apically (figs. 5 and 6)[...] A. seminigra; — Forcipes superiores broad apically (fig .20)[...] A, gongalvesi sp. n.; 4. First, second and third sternites yellowish [...] A. angrensis sp. n.; — All sternites brownish to black [...] A. sabroskpi sp. n.; The material studied belongs to the Instituto Oswaldo Cruz collections, where is located the types of new species.

Contribuição ao conhecimento da sistemática e biologia de buprestídeos minadores do gênero Pachyschelus Solier, 1833: (Coleoptera, Buprestidae)

Buprestid leaf-miners are generally included in the subtribe Trachytes. The genera belonging to this subtribe are commonly very rich in number of species and their systematics envolves huge difficulties. On the other hand the biological knowledge on those insects is very poor. The A. tries to clarify the systematical status of two species of Pachyschelus - P. subundulatus Kerr. and P. fulgidipennis Lucas, and redescribes also P. binderi Obenberger. The hosts of the first two species are recorded, namely: Terminalia catappa (Combretaceae) - host-plant of P. subundulatus and Luhea spp. (Tiliaceae) - host-plant of P. fulgidipennis. The mines, developmental stages and habits of the three species are described and is made a full redescription of the adults, both male and female. The study is based on reared material from mined leaves, as well as insects assembled in several brazilian collections, both private and public ones. The importance of some biological facts as well as some morphological characters are stressed. The knowledge of the host-plants and the shape and other structural features of the mine were found to be helpfull to the identification of the species. Some morphological features of adults also prooved to be of systematical value. Besides the female pygidium and the male genitalia, the tibiae of the third pair of legs show some intersting structural details, reasonably alike in both sexes and quite different in each species.
