Chromosome number and morphology are relevant aspects of genomic organization of eukaryotes and are considered key components to comprehend evolutionary mechanisms and karyotypic differentiation. Social wasps belonging to the tribe Epiponini show complex social characteristics that make these insects interesting models for genetic and evolutionary studies.(More)
Toxin A (TxA) is able to induce most of the classical features of Clostridium difficile-associated disease in animal models. The objective of this study was to determine the effect of an inhibitor of adenosine deaminase, EHNA [erythro-9-(2-hydroxy-3-nonyl)-adenine], on TxA-induced enteritis in C57BL6 mice and on the gene expression of adenosine receptors.(More)
We describe here the genome sequencing and annotation of Weissella ceti strains WS74 and WS105, isolated from diseased rainbow trout in Brazil. The two genomes were sequenced with an Ion Torrent personal genome machine (PGM) using a fragment library. The genomes of strains WS74 and WS105 consist of circular chromosomes 1,389,513 bp and 1,390,396 bp long,(More)
The pathogenesis of the Brucella-induced inflammatory response in the bovine placenta is not completely understood. In this study we evaluated the role of the B. abortus Type IV secretion system and the anti-inflammatory factor BtpB in early interactions with bovine placental tissues. Transcription profiles of chorioallantoic membrane (CAM) explants(More)
This paper describes the complete genome sequence of Francisella noatunensis subsp. orientalis strain FNO01, which was isolated during the first outbreak of francisellosis in cultured Nile tilapia in Brazil. The genome is composed of a circular chromosome with 1,859,830 bp and a G+C content of ~32%.
In this study, we isolated and characterized a lytic Lactococcus lactis bacteriophage from the sera of a failed fermentation. The phage was isolated and cultured in L. lactis subsp. cremoris in M17 medium. The isolated bacteriophage was characterized by multiplex PCR, pulsed-field electrophoresis, DNA restriction digestion, analysis of the N-terminal(More)
Partamona rustica is a stingless bee that occupies dry forests of Brazil, such as the cerrado (savanna-like biome) and caatinga (xeric shrubland and thorn forest), ranging from the northern portion of the state of Minas Gerais to the southwestern portion of the Bahia state. As this bee is endemic to these environments and its biology is poorly known, the(More)
In 1985, Laudau & Gleitman first outlined the syntactic bootstrapping hypothesis, in their book Language and Experience – Evidence from a blind child, followed in 1990 by Lila Gleitman’s article “The structural sources of verb meanings” (in Language Acquisition). They proposed that young children might learn the meaning of words (and in particular, verbs),(More)
