Benthic Ciliates

During the period from 2001 to 2002, we examined samples of water and sediment from five stations in Sepetiba Bay, located in the south region of Rio de Janeiro state, Brazil. We identified 32 species of ciliate protists representing seven classes: Karyorelictea, Heterotrichea, Spirotrichea, Litostomatea, Phyllopharyngea, Protostomatea and Oligohymenophorea. Among the Spirotrichea, we discovered Pseudokeronopsis sepetibensis n. sp., characterized by a unique combination of three features: 3 contractile vacuoles, an inconspicuous mid-ventral row, and 4 5 frontoterminal cirri. It showed yellow-greenish coloration and elongated body outline (100 140 m x 20 26 m). On average, there were 44 adoral membranelles, 50 left marginal cirri, 48 right marginal cirri and 41 mid-ventral cirri disposed in a straight row past the level of the oral region. Other features include 4 frontoterminal cirri and a constant number of 3 transverse cirri; 8 frontal cirri (4 anterior and 4 posterior arranged as an atypical bicorone).

Abstract The aim of this study was to analyze the spatial distribution of the tuberculosis endemic in Rio de Janeiro State from 2002 to 2011. A retrospective study was conducted in the state of Rio de Janeiro from 2002 to 2011. Spatial analysis techniques were used to describe the distribution of tuberculosis incidence in the state. Multilevel Poisson regression model was used to access the relationship of tuberculosis and the following factors: “sex”, “age-group” and “diagnostic year” (individual-level factors). Demographic density and municipality were also included in the model as contextual-level factors. A reduction in endemic tuberculosis was observed over the years. The highest incidence rates were concentrated on the south coast of the state, covering Rio de Janeiro City (capital) and neighboring cities. We detected a significant clustering of high TB incidence rates on the south coast of the state and a cluster of low incidence in the northeastern region of state. The risk of tuberculosis was higher in early 2000s, in males and in 40-59 age group. Metropolitan regions are important risk areas for the spread of tuberculosis. These findings could be used to plan control measures according to the characteristics of each region.

This is the first surveillance of calcareous sponges (Porifera, Calcarea) from Ilha Grande Bay in the Southwest coast of Rio de Janeiro, Brazil. Two islands were surveyed and the description of the calcareous sponges collected is presented here. A total of 98 specimens were collected, from five species. Clathrina aspina has its geographic distribution extended to the South of Rio de Janeiro state; Sycettusa cf. hastifera, a species from the Red Sea, and previously cited to the North of Rio de Janeiro state, was now found in Ilha Grande Bay; three new species to science are being described here: Clathrina angraensis sp. nov., Leucandra serrata sp. nov., and Paraleucilla perlucida sp. nov.
