Última A preliminary survey of M. hyopneumoniae virulence factors based on comparative genomic analysis Genet. Mol. Biol. Ferreira,Henrique Bunselmeyer; Castro,Luiza Amaral de. Mycoplasma hyopneumoniae is the etiological agent of porcine enzootic pneumonia (PEP), a major problem for the pig industry. The mechanisms of M. hyopneumoniae pathogenicity allow to predict the existence of several classes of virulence factors, whose study has been essentially restricted to the characterization of adhesion-related and major antigenic proteins. The now available complete sequences of the genomes of two pathogenic and one non-pathogenic strain of M. hyopneumoniae allowed to use a comparative genomics approach to putatively identify virulence genes. In this preliminary survey, we were able to identify 118 CDSs encoding putative virulence factors, based on specific criteria ranging from predicted cell surface location or variation between...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572007000200012 Necrotic enterocolitis in pigs naturally infected by porcine circovirus type 2 Ciência Rural Zlotowski,Priscila; Corrêa,André Mendes Ribeiro; Barcellos,David Emílio Santos Neves de; Cardoso,Marisa Ribeiro de Itapema; Vasconcelos,Anílton Cesar; Castro,Luiza Amaral de; Driemeier,David. Samples of intestine with necrotic enteritis from 63 pigs naturally infected with porcine circovirus type 2 (PCV2) were studied. Colon was the main target of PCV2 associated necrotic enteritis in 60 cases. Immunohistological investigations were carried out to detect the presence of PCV2 in necrotic lesions and to identify the type of cells infected by the virus. Crypt epithelial cells had positive labelling for PCV2 in 17 cases. Depletion of goblet cells occurred in 10 cases. In 24 necrotic enteritis cases, co-infection of PCV2 and Salmonella was identified. An increased rate of apoptosis in the crypt epithelial cells of the large intestine from PCV2 of naturally infected pigs was observed. Immunohistochemical findings confirmed the presence of PCV2 within... Tipo: Info:eu-repo/semantics/article Palavras-chave: Necrotic enterocolitis; PCV2 infection; Swine.
