Rv2617c and P36 are virulence factors of pathogenic mycobacteria involved in resistance to oxidative stress
(Taylor & Francis, 2019-12)In this study, we characterized the role of Rv2617c in the virulence of Mycobacterium tuberculosis. Rv2617c is a protein of unknown function unique to M. tuberculosis complex (MTC) and Mycobacterium leprae. In vitro, this ... -
Analysing nonsynonymous mutations between two Mycobacterium bovis strains with contrasting pathogenic profiles
(Elsevier, 2019-12)Mycobacterium bovis (M. bovis) is the causative agent of bovine tuberculosis, a chronic infectious disease that can affect cattle, other domesticated species, wild animals and humans. This disease produces important economic ... -
Symbionts do not affect the mating incompatibility between the Brazilian-1 and Peruvian morphotypes of the Anastrepha fraterculus cryptic species complex
(Springer Nature, 2019-12)The South American fruit fly, Anastrepha fraterculus, is clearly undergoing a speciation process. Among others, two of their morphotypes, the Brazilian-1 and Peruvian, have accumulated differences in pre- and post-zygotic ... -
Highly efficient production of rabies virus glycoprotein G ectodomain in Sf9 insect cells
(Springer, 2019-11)In the present study, we developed a complete process to produce in insect cells a high amount of the ectodomain of rabies virus glycoprotein G (GE) as suitable antigen for detecting anti-rabies antibodies. Using the ... -
Ursolic acid : a novel antiviral compound inhibiting rotavirus infection in vitro
(Elsevier, 2019-11)Rotavirus is one of the leading causes of severe acute gastroenteritis in children under 5 years of age, mainly affecting developing countries. Once the disease is acquired, no specific treatment is available; as such, the ... -
Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
(Academia Brasileira de Ciências, 2019-10)Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical ... -
The overexpression of antifungal genes enhances resistance to rhizoctonia solani in transgenic potato plants without affecting arbuscular mycorrhizal symbiosis
(Elsevier, 2019-10)The biological control of fungal diseases through the use of genetically modified (GM) plants could decrease the input of chemical pesticides. To overcome possible losses in potato (Solanum tuberosum) yield because of ... -
Draft genome sequence data of Cercospora kikuchii, a causal agent of Cercospora leaf blight and purple seed stain of soybeans
(Elsevier, 2019-10)Cercospora kikuchii (Tak. Matsumoto & Tomoy.) M.W. Gardner 1927 is an ascomycete fungal pathogen that causes Cercospora leaf blight and purple seed stain on soybean. Here, we report the first draft genome sequence and ... -
A thermostable GH8 endoglucanase of Enterobacter sp. R1 is suitable for β- glucan deconstruction
(Elsevier, 2019-11)Glycoside hydrolase family 8 (GH8) includes endoglucanases, lichenases, chitosanases and xylanases, which are essential for polysaccharides breakdown. In this work, we studied a thermally stable GH8 from the cellulose ... -
Diversity of Empruthotrema Johnston and Tiegs, 1992 parasitizing batoids (Chondrichthyes: Rajiformes and Myliobatiformes) from the Southwest Atlantic Ocean, with description of three new species
(Springer, 2019-11)During an extensive research project involving 519 specimens of batoids, including 13 species of Rajiformes and Myliobatiformes (Chondrichthyes) from the Argentine Sea, three new species of Empruthotrema were found and are ... -
Immunisation of cattle against Babesia bovis combining a multi-epitope modified vaccinia Ankara virus and a recombinant protein induce strong Th1 cell responses but fails to trigger neutralising antibodies required for protection
(Elsevier, 2019-10)Protection against the intraerythrocytic protozoan parasite Babesia bovis depends on both strong innate and adaptive immune response, this latter involving the presentation of parasite antigens to CD4+ T-lymphocytes by ... -
L-cysteine transporter-PCR to detect hydrogen sulfide-producing Campylobacter fetus
(2019-11)Phenotypic differences between Campylobacter fetus fetus and C. fetus venerealis subspecies allow the differential diagnosis of bovine genital campylobacteriosis. The hydrogensulfide production,for example,is atrait exclusive ... -
Matrix assisted laser desorption ionization-time-of-flight mass spectrometry identification of mycobacterium bovis in bovinae
