The global population of SARS‑CoV‑2 is composed of six major subtypes
Morais, Ivair José; Polveiro, Richard Costa; Souza, Gabriel Medeiros; Bortolin, Daniel Inserra; Sassaki, Flávio Tetsuo; Lima, Alison Talis MartinsThe World Health Organization characterized COVID-19 as a pandemic in March 2020, the second pandemic of the twenty-frst century. Expanding virus populations, such as that of SARS-CoV-2, accumulate a number of narrowly shared polymorphisms, imposing a confounding efect on traditional clustering methods. In this context, approaches that reduce the complexity of the sequence space occupied by the SARS-CoV-2 popul...
Polymorphism analysis of the apxIA gene of Actinobacillus pleuropneumoniae sero...
Santos, Lucas Fernando dos; Polveiro, Richard Costa; Moreira, Thalita Scatamburlo; Vidigal, Pedro Marcus Pereira; Chang, Yung-FuThe bacterium Actinobacillus pleuropneumoniae is the etiological agent of Contagious Porcine Pleuropneumonia, a disease responsible for economic losses in the swine industry worldwide. A. pleuropneumoniae is capable of producing proteinaceous exotoxins responsible for inducing hemorrhagic lesions, one of which is ApxI. Few studies have conducted an in-depth evaluation of polymorphisms of the nucleotides that ma...
Effect of different digestible isoleucine/lysine ratios for broiler chickens
Tavernari, Fernando de Castro; Lelis, Guilherme Rodrigues; Carneiro, Paulo Roberto de Oliveira; Vieira, Rodolfo Alves; Polveiro, Richard CostaTwo experiments were conducted to evaluate different digestible isoleucine/lysine ratios on diets for broiler chickens in the starter (7 to 21 days) and finishing (30 to 43 days) phases. For the tests, the experimental design was of randomized blocks with seven treatments (six different digestible isoleucine/lysine ratios and a control treatment) and eight repetitions of 25 and 20 birds (COBB males) per experim...
