Contribution à l'étude des infusoires parasites du coecum de l'hydrocheire (Hydrocheirus capybara L.): I. La famille des cycloposthiidae

Os autores referem inicialmente que os ciliados da capivara (Hydrochoerus capibara L.) são conhecidos pelos estudos de MARQUES DA CUNHA & MUNIZ bem como de FLÁVIO DA FONSECA. Fazem o estudo em material recentemente colhido em viagem ao Brasil e agradecem às pessoas que facilitaram êstes estudos. Dizem das técnicas usadas na coleta e estudo do material. Trabalhando o material colecionado em uma capivara sacrificada em Ribeirão Prêto estudam os representantes da família Cycloposthidae. Dividem as espécies do gênero Cycloposthium em três secções: a primeira com C. hydrochoeri Cunha, 1915; a segunda com C. minutum Cunha & Muniz, 1927; C. lenticularis sp. n. e C. elongatum sp. n.; a terceira com C. caudatum Cunha & Muniz, 1927 e C. compressum Cunha 1915 incluidas em novo subgênero: Diplolophus. Estudam pormenorisadamente C. hydrochoeri fazendo numerosas observações da morfologia em exemplares de preparação total, bem como em cortes. Na segunda secção dão a diagnose das 3 espécies nela incluídas, das quais duas novas para a ciência: C. lenticularis, com corpo quase tão largo como longo, 40 a 60 μ de comprimento por 40 a 45 μ de largura e processos caudais muito curtos ora acuminados ora arredondados. C. elongatum, de tamanho relativamente grande, medindo de comprimetno 160 a 200 μ por 60 a 90 μ de largura. Para a terceira secção estabelecem um novo subgênero - Diplolophus - com D.(D.) compressum e D.(D.) caudatum. O subgênero é caracterisado, principalmente, por serem os cirros adorais distribuídos em duas espirais: uma interna e outra mais externa. Finalisando o trabalho fazem comentários sôbre os componentes da família Cycloposthidae.

The Paranuclear corpuscles in poikilothermic vertebrates: description of a new species of Pirhemocyton in Iguana iguana of Venezuela, with remarks on the nature of these organisms and their relation to applied parasites

This paper discusses the relations between the genera Toddia and Pirhemocyton, describing certain cytochemical reactions that clarify their nature, and discussing the position of these organisms as being of a parasitic or viral nature. A new species of Pirhemocyton is described form Iguana iguana from Mamo, Marapa (Dto. Federal) of Venezuela; characterized by rectangular globoids with rounded borders. Attempts at experimental infections of other genera of lizerds indicate that the new species, Pirhemocyton iguanae, is specific to the natural host, Iguana iguana. The course of the parasitemia in the lizard is described.

A contribution to the study of the Haematozoon parasites of bats: a new mammalian haemoproteid, Polychromophilus deanei n. sp

Polychromophilus deanei n. sp. (Haemosporidiidea, Haemoproteidae) is described from a vespertilionid bat, Myotis nigricans nigricans (SCHINZ, 1821), captured on the Rio Maracapuçu, Município of Abaetetuba, Pará, Brasil. Mature oocysts were found in 2 specimens of the ectoparasite Basilia sp., taken form the infected animal. The parasite is probably the same as that previously described in another bat, Glossophaga soricina soricina, from the same general area, by DEANE & DEANE in 1961.

Blood parasites of some birds from São Paulo State, Brazil

A total of 3.449 birds, representing 195 species of 33 families from three areas in São Paulo State, Brazil, were examined for hematozoa during the period 1967-1972. Only 268 birds (7.8%) of 21 families harbored a blood parasite, which represented by species of Haemoproteus (3.5%), microfilaria (2.6%), Plasmodium (1.8%), Trypanosoma (0.8%) and Leucocytozoon (0.06%). The prevalence was similar in each of the six years of the study but a marked decrease in prevalence was noted in February and June of each year. The prevalence of parasitism was significantly different in each of the three areas sampled.

Maritremopsis mariettavogeae sp. n. (Trematoda, Microphallidae) and Amphimerus lancea (Diesing, 1850) (Trematoda, Opisthorchiidae) parasites of Nectomys Squamipes (Rodenta) in Brazil

In this paper two species of trematodes recovered from nectomys squamipes from Goiás State, Brazil, are presented. Maritremopsis mariettavogeae sp. n. is compared to M. proxilum (Caballero & Montero-Gei, 1961) and M. belopolskaiae (Caballero, 1964). Amphimerus lancea originally described from a cetacean host, is for the first time referred in a rodent.
