TL;DR: Genomic comparisons revealed that reduction in genome size implied loss of redundant metabolic pathways, with maintenance of alternative routes in different species, and indicated a likely transfer event of hemagglutinin-coding DNA sequences from M. gallisepticum to M. synoviae.
Journal ArticleDOI
A set of recombinant antigens from Echinococcus granulosus with potential for use in the immunodiagnosis of human cystic hydatid disease.

TL;DR: In subclass‐specific ELISA, different IgG isotypes showed dominance in the response for each of the recombinant antigens, indicating that this would be the subclass of choice to be assessed for these recombinant proteins.
Journal ArticleDOI
Association of slow N-acetyltransferase 2 profile and anti-TB drug-induced hepatotoxicity in patients from Southern Brazil
Lia Gonçalves Possuelo,J. A. Castelan,T. C. de Brito,Andrezza Wolowski Ribeiro,Patrícia Izquierdo Cafrune,P. D. Picon,Adalberto R. Santos,Raquel Lima de Figueiredo Teixeira,Tatiana Schäffer Gregianini,Mara H. Hutz,Maria Lucia Rosa Rossetti,Arnaldo Zaha +11 more
TL;DR: Findings show that HIV-positive patients that have the slow acetylation profile are significantly associated with a higher risk of developing hepatotoxicity due to anti-TB drugs.
Journal ArticleDOI
Mutations in katG, inhA, and ahpC genes of Brazilian isoniazid-resistant isolates of Mycobacterium tuberculosis
Márcia Susana Nunes Silva,Simone Gonçalves Senna,Marta Osório Ribeiro,Andréia Rosane de Moura Valim,Maria Alice da Silva Telles,Afrânio Lineu Kritski,Glenn P. Morlock,Robert C. Cooksey,Arnaldo Zaha,Maria Lucia Rosa Rossetti +9 more
TL;DR: The presence of mutations in specific regions of the katG, inhA, and ahpC genes was analyzed with 69 Mycobacterium tuberculosis isoniazid-resistant isolates from three Brazilian states.
Journal ArticleDOI
Proteomic analysis of the Echinococcus granulosus metacestode during infection of its intermediate host
Karina Mariante Monteiro,Marcos Oliveira de Carvalho,Arnaldo Zaha,Henrique Bunselmeyer Ferreira +3 more
TL;DR: A proteomic analysis of the E. granulosus metacestode during infection of its intermediate bovine host provides valuable information on parasite survival strategies in the adverse host environment and on the molecular mechanisms underpinning CHD immunopathology.
