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...
Nematophagous fungi combinations reduce free-living stages of sheep gastrointes...
Silveira, Wendeo Ferreira da; Braga, Fabio Ribeiro; Tavela, Alexandre de Oliveira; Santos, Lucas Fernando dos; Domingues, Rafael ReisGastrointestinal nematodes (GIN) can reduce or limit sheep production. Currently there is a clear deficiency in the action of drugs for the control of these parasites. Nematophagous fungi are natural enemies of GIN. Fungal combinations have potential for reducing GIN populations. The aim of this study was to evaluate the efficiency combinations of nematophagous fungi in sodium alginate matrix pellets for the bi...
Investigation of genetic diversity in Mycoplasma hyopneumoniae and Mycoplasma h...
Santos, Lucas Fernando dosFundação de Amparo a Pesquisa do Estado de Minas Gerais; Coordenação de Aperfeiçoamento de Pessoal de Nível Superio; As duas espécies de Mycoplasma mais prevalentes na indústria suinícola são Mycoplasma hyopneumoniae e Mycoplasma hyorhinis. Estes patógenos podem causar perdas econômicas significativas para os produtores e para a indústria. Variabilidade genética tem sido observada em cepas de M. hyopneumoniae u...
Estudo filogenético do gene apxIA de Actinobacillus pleuropneumoniae sorotipo 5...
Santos, Lucas Fernando dosFundação de Amparo a Pesquisa do Estado de Minas Gerais; The toxins produced by Actinobacillus pleuropneumoniae (App) are recognized as major virulence factors found in this pathogen. Apx toxin I has strong hemolytic and cytotoxic activity, and this toxin has a high cytotoxic activity against pulmonary macrophages and neutrophils in swine. This exotoxin is produced by different serotypes, including the serotype...
