Ichthyological Overview and Remarks on Freshwater Fishes from Capim River, Lower Amazon Basin, Brazil  [PDF]
Júlio Cesar Garavello, Alexandre Kannebley de Oliveira
Open Journal of Ecology (OJE) , 2014, DOI: 10.4236/oje.2014.413068
Abstract: The Capim River drainage should be considered small and thin by comparison with large Amazonian rivers. It rises by confluence of the Surubiú and Ararandeua rivers near 400 m high and their headwaters would be comfortably included in the Dry Emerged Lowland (terra firme) forest area of Sternberg’s Amazonian concept. Because of this reason the freshwater fish fauna of Capim River is comprised mainly by Amazonian fish families found in tributaries also with origin in terra firme areas. The ichthyofauna from the main channel of the poorly sampled Capim River, in the stretch between its confluence with Tauarí River and its mouth at Guamá River, is herein reported by way of rapid assessment. Also broad comparisons were made among freshwater fishes of the Capim with that from Tocantins and Guamá rivers. Two rapid access research surveys of collecting ichthyological material were performed in dry and humid periods of the year 1998 comprising the regional hydrologic cycle. The ichthyological diversity showed by the 461 studied specimens includes 79 species probably derived from Guamá and Tocantins rivers. These species are distributed between two situations: 1) downstream Capim River, at confluence with Guamá River, where is under tidal waters influence and periodically flooded, and 2) upriver Capim that is less humid and with water rapids, independent from sea hydrologic influence. This fish fauna includes local species common at high areas of the Amazonian Dry Emerged Lowland that are in part shared with that from Tocantins River. In view of these observations, we assume that the Capim River freshwater ichthyofauna may reflect diverse origin from the simple transfer of populations from Guamá River, but originate through a more complex process including the past ichthyofauna of the earlier drainages of terra firme forest and their reorganization.

Abstract: OBJETIVO: Reconhecer as características e trajetória da Revista de Saúde Pública pela análise da produ o científica por ela veiculada, no período de 1967-2005. MéTODOS: Foram analisados por métodos cientométricos dados referenciais dos artigos publicados na Revista e recuperados nas bases de indexa o do Institute for Scientific Information (ISI)/Thomson Scientific (Web of Science), National Library of Medicine (PubMed) e Scientific Eletronic Library Online (SciELO). RESULTADOS: A Revista, sendo a única na área da saúde pública no Brasil, indexada pela ISI/Thomson Scientific, destaca-se como veículo de divulga o da produ o científica brasileira em saúde pública e exibe crescimento geométrico de publica es e cita es, cujas taxas anuais s o de 4,4% e 12,7%, respectivamente. O número de autores cresceu de uma média de cerca de dois por item publicado até 3,5 para os dias atuais. Embora os artigos originais de pesquisa predominem, nos últimos anos aumentou o número de revis es, estudos multicêntricos, ensaios clínicos e de valida o; cresceu também o número de artigos publicados em língua estrangeira, com 13% do total, destacando-se a participa o da Inglaterra, Estados Unidos, Argentina e México. Aumentou o número e diversidade de revistas que citam a Revista de Saúde Pública, com expressiva participa o de revistas internacionais. A distribui o de autorias por autor da Revista ajusta-se muito bem à Lei de Lotka, mas seus parametros sugerem maior concentra o e menor dispers o do que o esperado. Entre os temas de interesse dos itens publicados, doen as infecto-parasitárias e vetores, promo o, políticas, administra o de saúde e epidemiologia, vigilancia e controle de doen as responderam por mais de 50% do volume total. CONCLUS ES: A Revista mostra grande dinamismo sem sinais que sugiram qualquer esgotamento ou estabilidade em futuro próximo. Há sinais de progressivo aumento de complexidade dos estudos publicados, bem como de maior multidisciplinaridade. A Revista parece alargar seu alcance e repercuss o embora continue fiel aos temas de interesse da saúde pública do Brasil.

Abstract:

Streptococcosis is one of the most important diseases in aquaculture, causing high rates of mortality in fish. ArtinM, an immunostimulant obtained from jackfruit (Artocarpus integrifolia) seed extract, enhances the innate immune response. The aim of this study was to examine the action of ArtinM on neutrophil haptotaxis to the peritoneal cavity of juvenile Nile tilapia (Oreochromis niloticus) inoculated intraperitoneally with Streptococcus agalactiae. After establishing the LD50 of S. agalactiae and the effective dose of ArtinM, 120 animals randomly distributed in 12 aquaria were divided into the following four treatment groups: G1, control; G2, via the intraperitoneal (i.p.) route inoculation with ArtinM; G3, i.p. inoculation with S. agalactiae and G4, i.p. inoculation with ArtinM and challenge with S. agalactiae. Six and 24 hours after treatment, the fish were sacrificed and peritoneal exudate and caudal vein blood samples were collected for analysis of the total number of leukocytes and neutrophils. To establish the optimal ArtinM concentration, the results were analyzed with a chi-square test at a 1% significance level. The experimental inoculation and challenge results were analyzed with the SASM-Agri software developed by Canteri et al. (2001) using the Scott-Knott’s test at a 5% significance level. The results of this study showed that i.p. inoculation with 1.0 μg ArtinM/animal has an effect on neutrophil haptotaxis to the peritoneal cavity in juvenile Nile tilapia. Therefore, ArtinM might represent a suitable prophylactic alternative in juvenile Nile tilapias inoculated with S. agalactiae.
