The female of Amblyomma multipunctum Neumann, 1899 is described for the first time, the species being easily recognized by the unusual formula 5/5 in the female's hypostoma, the formula of the male's being 4/4. A redescription of the male is presented.

Based on the available data from the Hospital responsible for the care of paralitic poliomyelitis cases in Rio de Janeiro City (Guanabara State) and adjacent areas, and the laboratory studies carried out on these patients, the authors analize epidemiological aspects of poliomyelitis in a period of ten years (1961 to 1970). Paralitic poliomyelitis remains a public health problem, with a typical incidence in the less than 4 year age group. All three poliovirus types have been prevalent for at least one period of time during the last ten years. Trivalent oral vaccine has been used since 1961 but the vaccination levels achieved were not enough to a permanent control of the disease. A definite seasonal distribution of cases could not be observed with the available data. Active mass campaign vaccinations with previous motivation of all segments of the population, specially the low-income groups instead of passive waiting of children in Vaccination Centers seems to be the best aproach to control poliomyelitis in this area.

Os autores estudam todo o material brasileiro pertencente ao gênero Prosthogonimus Luehe, 1899, depositado na Coleção Helmintológica do Instituto Oswaldo Cruz, determinado e sem determinação, e concluem que apesar de apresentar grande variação em seus caracteres, pertence à uma única espécie Prosthogonimus ovalus (Rudolphi, 1803). Essa variação já havia sido observada anteriormente por Travassos (1922-1928) e confirmada experimentalmente por Boddeke (1960). São apresentadas 49 figuras e 5 quadros com as medidas correspondentes, mostrando as variações encontradas.

Phyllodistomum rhamdiae n. sp. is described based on specimens collected from the urinary bladder of freshwater catfishes, Rhmdia quelen, caught from the Guandu river, outskirts of Rio de Janeiro, State of Rio de Janeiro, Brazil. The new species is characterized by its sucker width ratio equal to 1:1, by the large size of the gonads and their spatial arrangement.

A description is given of the shell, head-foot, pulmonary wall, reproductive system and radula of Biomphalaria subprona (Martens, 1899). A diagnosis between it and two other congeneric species under 10 mm in shell diameter occurring in Middle America (Biomphalaria helophila and B. schrammi) is presented.

The ultrastructure of endogenous stages of Eimeria ninakohlyakimovae was observed in epithelial cells of cecum and colon crypts from a goat experimentally infected with 2.0 x 105 oocysts/kg. The secondary meronts developed above the nucleus of the host cell. The nucleus first divides and merozoites then form on the surface of multinucleated meronts. Free merozoites in the parasitophorous vacuole present a conoid, double membrane, one pair of rhoptries, micronemes, micropore, anterior and posterior polar ring, a nucleus with a nucleolus and peripheral chromatin. The microgamonts are located below the nucleus of the host cell and contain several nuclei at the periphery of the parasite. The microgametes consist of a body, a nucleus, three flagella and mitochondria. The macrogamonts develop below the nucleus of the host cell and have a large nucleus with a prominent nucleolus. The macrogametes contain a nucleus, wall-forming bodies of type I and type II. The young oocysts present a wall containing two layers and a sporont

Panstrongylus rufotuberculatus is reported for the first time in Argentina. Four adults were attracted by the light of human dwellings in Calilegua National Park, Jujuy, at 1150 masl within the subtropical humid forest. The individuals were similar to those described in the literature. The epidemiological significance of this species is very low in the area, although deforestation might increase its role in the transmission of Trypanosoma cruzi.

O objeto desse estudo é a reconfiguração do Serviço de Enfermagem do Hospital Estadual Santa Maria, frente a uma nova política contra a tuberculose no Brasil. Objetivos: descrever as circunstâncias que ensejaram a implantação do novo Programa de Ação na Luta contra a Tuberculose no Brasil, e discutir as estratégias utilizadas pelas enfermeiras diplomadas do Hospital Estadual Santa Maria, no Estado da Guanabara, para adequar a assistência de enfermagem ao novo programa de combate à tuberculose. Estudo histórico-social. Para sua elaboração, foi realizada pesquisa documental, entrevistas e depoimentos de enfermeiras da época. A análise do corpus documental, apoiada pelos conceitos de habitus, campo e poder simbólico de Pierre Bourdieu, se fez com base em documentos escritos, orais e fontes secundárias. Resultados: a reconfiguração do serviço de enfermagem se deu sob a liderança de uma enfermeira cujo capital simbólico lhe conferia poder e prestígio para implementar as mudanças necessárias. Pode-se concluir que a atuação dessa enfermeira possibilitou a implantação do novo programa, e contribuiu para demarcar o espaço e a importância da enfermeira diplomada na assistência aos acometidos de tuberculose, tanto nos aspectos de prevenção quanto nos de cura.

Prof. Ernest Wenkert's connections with Brazil on this side of the Atlantic Ocean involved two important links: Profs. Jayr de Paiva Campello and Otto R. Gottlieb. The former, along with Prof. Giuseppe Cilento, was one of those responsible for setting up the Institute of Chemistry of UNICAMP, while Otto Gottlieb was the great pioneer of Natural Products Chemistry in Brazil. The bridge between these two professors and Wenkert paved the way for several Brazilian chemists to visit the USA, and was also important for bringing some PhDs to Brazil.
