Bacteria and protozoa populations in groundwater in landfill area in São Carlos, SP Rev. Microbiol.
Fusconi,Roberta; Godinho,Mirna Januária Leal.
The microbial populations of groundwaters were analyzed in a region under the influence of a landfill (piezometer L12) in the town of São Carlos, São Paulo, Brazil, and in an area not influenced by the landfill (piezometer L5). Heterotrophic bacteria were counted by spread plate method and the number of protozoa was estimated by the most probable number method. There was a larger number of organisms in well L12, with a mean value of 15.76 x 104 CFU/ml for bacteria and 9.7 MPN/ml for protozoa, whereas the mean values for piezometer L5 were 2.88 x 104 CFU/ml for bacteria and 3.4 MPN/ml for protozoa. The greater abundance detected in piezometer L12 may be related to the influence of the leachate through the landfill on the microbial populations, also...

Diseases of cultured molluscs in Australia ArchiMer
Lester, R.
Three mollusc species are cultured commercially in Australian tropical and warm temperate waters: the Sydney rock oyster Saccostrea commercialis , the pearl rock oyster is susceptible to two protozoans: Marteilia sydneyi , which is the cause of QX Disease and infects oysters during the summer; and Mikrocytos roughleyi which is associated with winter mortality. It also harbours mudworm, Polydora websteri a parasite farmers try to avoid by growing oysters on racks. Transported pearl oysters Pinctada maxima die with heavy infections of Vibrio harveyi . Cultured giant clams Tridacna gigas are pestered by pyramidellid snails and some carry Perkinsus sp., a protozoan common in reef bivalves. Deaths in mollusc hatcheries have been associated with Vibrio tubiashi...

Efeito de metodos de coleta de fluido ruminal em bovinos sobre alguns parametros ruminais e microbiologicos. Repositório Alice
OLIVEIRA, M.D.S. de; SAMPAIO, A.A.M.; VIEIRA, P.de F.; FREITAS, J.C.M. de; SHOCKEN-ITURRINO, R.P..
Estudou-se o efeito de tres metodos de coleta (manual, bomba e vacuo e sonda masoesofageana) sobre os teores de acidos graxos volateis totais (AGVt), nitrogenio amoniacal e numero de protozoarios no fluido ruminal de bovino. Utilizou-se o delineamento inteiramente casualizado, com tres tratamentos e cinco repeticoes. Os resultados revelaram que o metodo da sonda masoesofageana proporcionou valores menores dos acidos propionico, butirico, AGVt e de nitrogenio amoniacal no fluido ruminal. O numero total de protozoarios nao foi afetado pelos metodos de coleta de conteudo ruminal. O metodo de coleta manual e por meio de bomba a vacuo mostraram-se eficientes para os parametros estudados.

Effects of Euglena (Euglena gracilis) supplemented to diet (forage: concentrate ratios of 60:40) on the basic ruminal fermentation and methane emissions in in vitro condition OAK
Aemiro, Ashagrie; Watanabe, Shota; Suzuki, Kengo; Hanada, Masaaki; Umetsu, Kazutaka.
An in vitro study was conducted to investigate the effect of different concentrations of Euglena (Euglena gracilis) on CH4 production, dry matter (DM) digestibility, volatile fatty acid (VFA) and ammonia N(NH3-N) concentration as well as on the protozoa population. The treatments considered were Euglena at concentrations of 0.0, 50, 100, 200, 400 and 1000 g/kg dry matter (DM) of the substrate (60:40 forage: concentrate ratio) incubated for 24 and 96 h using an in vitro continuous gas production and in vitro two-stage digestion procedure, respectively. The data were subjected to polynomial regression analysis. Methane emissions (ml/g DM) decreased at an increasing rate, generally with increasing concentration of Euglena but also exhibited quadratic (P<...

Estado de conocimiento de los tecamebianos dulceacuícolas de Chile Gayana
Zapata Madrid,Jaime.
Las tecamebas son un grupo de protozoos que viven principalmente en las comunidades acuáticas y de ambientes húmedos (suelos, turberas, etc.), en donde juegan un importante rol como descomponedoras de celulosa y lignina; además participan activamente en diversos procesos biológicos que ocurren en los ecosistemas acuáticos. Con respecto al conocimiento de las tecamebas en Chile, éste se mantiene en un estado muy incipiente, de ahí la necesidad de contar con más especialistas, ya que este grupo está adquiriendo cada vez más importancia por su uso en problemas de paleolimnología, como bioindicadores de ambientes lacustres contaminados, como indicadores pedológicos, entre otros.

Factors affecting bacterial biomass and growth in the Duplin River estuary and coastal Atlantic Ocean. ArchiMer
Fallon, R; Newell, S; Sherr, B; Sheer, E.
Bacterial numbers and growth rates were measured in coastal, planktonic systems of the Western Atlantic ocean. Seasonal responses in growth rates of the bacterial assemblage were present at some sites, but these may be related to seasonal changes in substrate supply rather than to changes in temperature. Bacterial growth rates tended to decline with increasing distance from shore. There was evidence for predator-prey population cycles in the bacteria and < 17 mu m protozoa in the Duplin River Estuary which may indicate that the bacterial assemblage serves as prey for protozoan populations. In summer, a significant negative correlation between mu (instantaneous growth rate) and cell numbers in the bacterial assemblage indicated that substrate limitation...

Flagellate protist abundance in phytotelmata of Aechmea distichantha Lem. (Bromeliaceae) in the upper Paraná river basin - doi: 10.4025/actascibiolsci.v35i4.17134 Biological Sciences
Duarte, Gisele Silva Costa; Alves, Geziele Mucio; Lansac-Tôha, Fernando Miranda; Velho, Luiz Felipe Machado; Lansac-Tôha, Fábio Amodêo.
In some Bromeliaceae species the leaf sheaths form a tank or phytotelma, accumulating water and organic detritus, conditions that allow the establishment of different communities. Thus, this study evaluated the relationship between diameter and volume of water in the tank of the bromeliad Aechmea distichantha Lem. and density of flagellates found in the phytotelmata, as well as the influence of the hydrological periods and proximity of sampled strata on the phytotelma patterns of abundance distribution. Samplings were conducted in two hydrological periods in 2010. In each sampling, four plants were collected from three different strata, classified according to the distance from the river level. A one-way ANOVA identified significant differences in...

Ingestion of a bacterivorous ciliate by the oyster Crassostrea gigas: Protozoa as a trophic link between picoplankton and benthic suspension-feeders ArchiMer
Le Gall, Solange; Bel Hassen, Malika; Le Gall, Pierre.
The linked concepts of 'microbial loop' and 'protozoan trophic link' have been very well documented in filter-feeding microzooplankton such as copepods, but have not been applied to energy transfer to benthic suspension-feeding macrofauna, with the exception of the recent demonstration of heterotrophic flagellate assimilation by mussels. The oyster Crassostrea gigas obtains energy resources by filtering microalgae (similar to 5 to 100 mu m). However, in turbid estuaries, light-limited phytoplanktonic production cannot entirely account for oyster energy requirements. Conversely, picoplankters (<2 mu m), which are main effecters of coastal energy flow and matter cycling, are not efficiently retained by oyster filtration. Ciliate protozoal as both...

Inhibitory effects of Melia azedarach L. extracts on the growth of Trichomonas vaginalis : Ultrastructural changes of Trichomonas vaginalis treated by Melia azedarach L OAK
Lee, Yun Sik; Chung, In Bai; Choi, Won Hyung; Cho, Yoo Jung; Chu, Jong Phil; Min, Byung-Il; Shin, Eun-Hee.
Meliae cortex (Melia azedarach Linne. var. japonica Makino, M. toosendan Siebold & Zucc) is one of the herbs used in oriental medicine for the treatment of various types of vaginitis. The present study was performed to examine the effects of Meliae cortex extracts on the growth and fine structure of Trichomonas vaginalis (T. vaginalis). Meliae cortex dose-dependently reduced the viability of T. vaginalis. In the electron microscopy study, we also observed the ultrastructural changes of T. vaginalis following the treatment with Meliae cortex. One to two hours after the addition of the extract of Meliae cortex, the movement of flagella and axostyle decreased, but the cell death did not occur. The fine structure of the cytoplasm was changed 30 min to 2...

Intestinal parasites of Alouatta caraya (Primates, Ceboidea): preliminary study in semi-captivity and in the wild in Argentina Mastozool. neotrop.
Milozzi,Carola; Bruno,Gabriela; Cundom,Elisa; Mudry,Marta D; Navone,Graciela T.
Endoparasitic infections are common in nonhuman primates and important factors in regulating their natural populations. Primates are particularly vulnerable to the infections of directly transmitted parasites because they often live in close social groups that facilitate their transmission. The main objective of this study was to provide baseline data on gastrointestinal parasites of semi captive and wild howler monkeys Alouatta caraya troops from Argentina. We collected 110 fecal samples from 38 howler monkeys from four troops, two of them kept in semi-captivity at the CRMAN, Córdoba, and two wild troops from Las Lomas, Corrientes. We identified six species of parasites: four Protozoa, Giardia lamblia, Blastocystis hominis, Eimeria sp. and Entamoeba coli;...

Abstract: This study evaluated the parasite fauna of farmed hybrid surubim (Pseudoplatystoma reticulatum x P. corruscans) and the host-parasite-environment relationship in two fish farms located in Mato Grosso do Sul, Central Brazil, South America. A total of 120 hybrids from two different farms, 60 in each season (30 in the hot and 30 in cold season) were examined during a year. Water quality was weekly measured to evaluate the interaction among environmental conditions and parasitism. Histopathology was used to observe the effects of the parasites and environment on the fish gills. The ciliate protozoan Ichthyophthirius multifiliis and the monogeneans (Ameloblastella sp., Amphocleithrium paraguayensis, Vancleaveus ciccinus, V. fungulus and V....
