Aspectos gametogênicos e histoquímicos de Iphigenia brasiliana (Lamarck) (Bivalvia, Donacidae) da Lagoa de Itaipu, Niterói, Rio de Janeiro, Brasil
Provedor de dados: Zoologia
Autores: Mesquita,Eliana de Fátima Marques de; Abreu,Marta Guimarães de; Lima,Francisco Carlos de.
Gametogenic and histochemical aspects of an edible bivalve, lphigenia brasiliana (Lamarek, 1818) from Itaipu Lagoon, Niterói, State of Rio de Janeiro, were studied. Between May 1998 and October 1999 a total of 120 clams were picked up. Samples of 10 animals were collected once a month. Specimens were fixed in Bouin's fixative for 4 hours or less and transferred to 10% formalin for 24 hours. The shell lenght has been measured with the valves lightly opened to permit the penetration of fixative solution deeply in the tissues. Transverse sections including digestive diverticula, mantle, gills, gonad and foot were obtained from the total body. After fixative treatment, tissues sections were embedded in paraffin, cut routinely at 5 µm and stained with Harris's...

Anatomia e histologia do conduto genital feminino de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae)
Provedor de dados: Zoologia
Autores: Mesquita,Eliana de Fátima Marques de; Coelho,Arnaldo Campos dos Santos; Santos,Jefferson Andrade dos.
In this paper the authors give an anatomical and histological analysis of the genital duct in mature and immature females of Pomacea canaliculata (Lamarck, 1822). Anatomically, the vagina has an equal dimension in its extension, varying in form and volume, according to the maturation period. In the immaturity, it has a smaller diameter and volume. In the maturity, the vagina increases in volume, having the aspect of a tumescent organ, and in certain specimens shows an albuminous pink thread in its lumen. Histologically, the calcigenic activity of the gland is evidentiated by the presence of an amorphous and basophilic mass, without nuclear material. This material has a fragmented aspect in the vagina lumen that reacts positively in van Kossa's coloured...

Anatomia e histologia do aparelho reprodutor masculino de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae)
Provedor de dados: Zoologia
Autores: Mesquita,Eliana de Fátima Marques de; Coelho,Arnaldo Campos dos Santos; Santos,Jefferson Andrade dos.
In this paper the authors give an anatomical and histological analysis of the male reproductive system of Pomacea canaliculata (Lamarck, 1822). Anatomically, the testis is better evidentiated than the ovary. In the structure of the testis a great number of very small channels converges to a single one. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. Histologically, the testis of immature males shows seminiferous ducts with round egg-shaped forms. In their lumens we could notice masses of cells that will originate spermatozoids. The penis has a conjunctive muscular sheath that can be seen in van Gieson's coloured preparations.

Ciclo reprodutivo do mexilhão Perna perna (Linnaeus) (Molusca, Bivalvia) da Lagoa de Itaipu, Niterói, Rio de Janeiro, Brasil
Provedor de dados: Zoologia
Autores: Mesquita,Eliana de Fátima Marques de; Abreu,Marta Guimarães de; Lima,Francisco Carlos de.
The gametogenic aspects of mussel Perna perna (Linnaeus, 1758) from Itaipu Lagoon, Niterói, were studied through November 1998 to October 1999. Microscopic analysis was carried out at low and high dry magnifications, as well as under oil immersion. The animals collected showed variation of size from 4.8 to 9.1 cm in total length and from 2.0 to 3.9 cm in total width. Most advanced gonadal stage was detected through May, August and October of 1999 for female specimens. Male advanced gonadal stage occurred in September of the same year. The sex-ratio (M:F) for P. perna was 64:52.

Enterococcus spp. Resistant to Multiple Antimicrobial Drugs and Determination of Fecal Contamination Levels in Mangrove Oysters (Crassostrea rhizophorae)
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Rubião,Cynthia Annes; Franco,Robson Maia; Mesquita,Eliana de Fátima Marques de; Miguel,Marco Antonio Lemos; Cabral,Claudius Couto; Fonseca,Ana Beatriz Monteiro.
ABSTRACT The aim of this study was to determine and compare the Most Probable Number (MPN) of Total Coliforms (TC), Escherichia coli and Enterococcus spp. and to characterize the antimicrobial resistance profiles of Enterococcus spp. isolated from oysters collected in the Barra de Guaratiba Mangrove, Rio de Janeiro, Brazil. The enumeration of E. coli has been used to indicate fecal contamination and hygienic-sanitary conditions of bivalve molluscs. Enterococci are capable to transfer several antimicrobial resistance genes to pathogenic bacteria, including those from Gram-negative group. The oysters were bought from local fishermen and a total of 123 individuals were analyzed. The TC, E. coli and Enterococcus spp. MPN mean were 26,300/100 g, 3,260/100 g and...

Cistos branquiais são descritos em oito exemplares de Tilapia nilotica, no Estado do Rio de Janeiro. Os cistos epiteliais consistiam de hipertrofia das células do epitélio branquial que mostravam um único e grande corpúsculo de inclusão basofílico. A enfermidade relatada apresenta as características peculiares da doença epiteliocística.
