| Objective: To carry out a situational diagnosis of interactions among man, animal and environment, to test intervention and control model in dogs and cats and lo make local population aware in order to improve human and animal health. Material and Method: The project "Evaluation of risks to the heath and local intervention associated to living together with dogs and cats" was carried out in the area invaded in Jardim Paraná, District of Brasilândia, São PauLo city, Brazil, in 2003 by the Center of Zoonosis Control of the São Paulo Municipality. Animal census, vaccinations, treatment of ectoparasitosis and endoparasitosis, animal register, animal sterilization, serological and soil examinations and removal of animals was carried through. Forty seven percent... |

| In intertidal mudflats, during low tide exposure, microphytobenthos (MPB) migrate vertically through the surface sediment and form, with the heterotrophic bacteria, a transient biofilm. Inside this biofilm, multiple interactions exist between MPB and bacteria. These micro-organisms secrete a wide range of extracellular polymeric substances (EPS), which are major components of the biofilm matrix. In this study, we used a tidal mesocosm experiment in order to decipher the interactions of the MPB-EPS-bacteria complex within the biofilm. We tried to determine if the EPS could control bacterial activities and/or production and/or richness according to the age of the biofilm and to the immersion/emersion period. The dynamics of biomasses of MPB and prokaryotes,... |

| The community of native bees from a transition area between Atlantic rain forest and Araucaria forest in Joinville, Santa Catarina state, Brazil, was studied regarding to species richness, relative abundance, floral resources and plant interactions. Observations were made monthly from 2008 to 2009, using entomological nets. 710 individuals of 88 species were sampled from the five bee subfamilies existing in Brazil. The bees were sampled on 62 plant species from 29 families. The most visited plant families were Asteraceae (48 %), Lamiaceae (10 %), Saxifragaceae (9 %) and Rosaceae (8 %). The bee subfamily with the highest species diversity was Halictinae (44 %), followed by Apinae (38 %), Andreninae (11 %), Megachilinae (8 %) and Colletinae (1 %). The... |

| Phytoplanktonic communities maintain a high diversity in a seemingly homogeneous environment, competing for the same set of resources. Many theories have been proposed to explain this coexistence despite likely competition, such as contrasted responses to temporal environmental variation. However, theory has developed at a faster pace than empirical evaluation using field data, which requires inferring drivers of community dynamics from observational time series. Here, we combine autoregressive models with a data set spanning more than 20 years of phytoplankton counts every two weeks, together with nutrients and physical variables. By comparing models dominated by nutrients or physical variables (hydrodynamics and climate), we first explore which abiotic... |

| As a contribution to understanding the potential impact of macroalgae on coral communities, this work evaluated the presence and dynamics of algae-coral interactions in two bays of the Santa Marta region. Two stations were sampled in Chengue Bay, located within the Tayrona Natural Park, and two other in the Santa Marta Bay which is adjacent to the city of Santa Marta. Three permanent 10 m belt transects were settled at each station, at which a total of 270 coral colonies were monitored monthly. Algae - coral interactions were recorded from each colony based on five categories defined by the distance between the coral tissue and the algal mat. A total of 1956 interactions were recorded, 67% of which corresponded to direct contacts, 22% to indirect contacts,... |

| Background: Massive mortality outbreaks affecting Pacific oyster (Crassostrea gigas) spat in various countries have been associated with the detection of a herpesvirus called ostreid herpesvirus type 1 (OsHV-1). However, few studies have been performed to understand and follow viral gene expression, as it has been done in vertebrate herpesviruses. In this work, experimental infection trials of C. gigas spat with OsHV-1 were conducted in order to test the susceptibility of several bi-parental oyster families to this virus and to analyze host-pathogen interactions using in vivo transcriptomic approaches. Results: The divergent response of these oyster families in terms of mortality confirmed that susceptibility to OsHV-1 infection has a significant... |

| Trace elements (As, Cd, Cu, Hg, Se and Zn) were determined in liver and kidney of pilot whales Globicephala melas Traill, 1809 collected from 7 schools caught at different seasons around the Faroe Islands. These and other biological data at our disposal enabled us to confirm and to define more accurately the relations shown previously between age, sex and trace element concentrations in marine mammals. The most striking features were: (1) the elevated levels of Cd and Hg in pilot whales compared to other marine mammals and to minimum adverse-effect levels established for humans; (2) the biocumulative behaviour of Cd and Hg; (3) the high correlations between Hg and Se, predominantly influenced by age; and (4) the high correlations between Cd and Zn, the... |

| The study analyzed the effect of mannitol on the pharmacokinetics (PK) of amikacin. Adult Wistar rats were treated as follows: Group 1 (G1) received mannitol for three days, Group 2 (G2) received mannitol plus 10 mg/kg of amikacin simultaneously, and Group 3 only amikacin. The PK study was conducted on the 4th day. For which, blood samples were drawn at fixed times during 24 h and immunoenzymatically analyzed. Results revealed significant differences (p<0.05) between the groups, e.g. Cmax were 62.26 ± 15.75 µg/ml for G1, 72.63 ± 24.80 µg/ml for G2 and 68.61 ± 27.40 µg/ml for G3. The AUC also differed in the three groups, being largest for G2, 222.52 ± 47.30 µg/ml/h, and smallest for G1, 135.59 ± 39.00 µg/ml/h. Alteration of the PK parameters observed... |

| Interactions between photosynthetic and non-photosynthetic microorganisms play an essential role in natural aquatic environments and the contribution of bacteria and microalgae to the nitrogen cycle can lead to both competitive and mutualistic relationships. Nitrogen is considered to be, with phosphorus and iron, one of the main limiting nutrients for primary production in the oceans and its availability experiences large temporal and geographical variations. For these reasons, it is important to understand how competitive and mutualistic interactions between photosynthetic and heterotrophic microorganisms are impacted by nitrogen limitation. In a previous study performed in batch cultures, the addition of a selected bacterial strain of Alteromonas sp.... |

| Macroalgae proliferation on coral reefs has been a recognized phenomenon for the past two decades and is generally entitled to the human activities on the coasts. Even thought, the role of competition in this process is not clear and it has been assumed that algae are competitively superior to corals, even when it has been demonstrated that this is not always the case. It is probable that the result of coral-macroalgae depends upon the species involved. The goal of this study was to demonstrate that there is a dependence relation between interaction category and interacting species. In order to resolve this, quantifications of interactions per category along 20 m transects were done on three representative localities at the Archipielago de San Bernardo.... |
