LEI0258 microsatellite variability and its relationship to B-F haplotypes in Brazilian (blue-egg Caipira) chickens
Provedor de dados: 74
Autores: Lima-Rosa,Carlos André da Veiga; Canal,Cláudio Wageck; Fallavena,Paulo Roberto Vargas; Freitas,Loreta Brandão de; Salzano,Francisco Mauro.
A total of 149 chickens from two different sources (one non-commercial, the other commercial) was tested for variability of the LEI0258 microsatellite. Fifty- three genotypes, explainable by 15 alleles, were found. There are clear allele and heterozygosity differences between the two samples. One of them was simultaneously studied for the MHC B-F haplotypes. Strong genetic disequilibrium was observed between the variants of the two systems, therefore providing a cheap alternative for MHC genotyping.

Performance comparison between broilers positive and negative for antibodies against the chicken anemia virus
Provedor de dados: 58
Autores: Rubin,Lauricio Librelotto; Ávila,Luiz Antônio Faccenda de; Ribeiro,Andréa Machado Leal; Wald,Vera; Canal,Cláudio Wageck.
The chicken anemia virus (CAV) is present in virtually every country investigated, Brazil including. The aim of this study was to determine what the difference in performance is between positive (progeny of breeders vaccinated or with natural infection) and negative broilers to the presence of antibodies against the CAV in currently intensive raising systems. As a result, it was observed that negative broilers were significantly heavier than positive broilers. Negative males had a final weight 5.43% higher than positive males. There was no significant difference among different treatments in relation to parameters as mortality and feeding conversion. These study indicated that the presence of antibodies against CAV in broilers - may it be through...

Provedor de dados: 58
Autores: Souza,Carine Kunzler; Streck,André Felipe; Gonçalves,Karla Ratje; Pinto,Luciane Dubina; Ravazzolo,Ana Paula; Barcellos,David Emílio dos Santos Neves de; Canal,Cláudio Wageck.
Abstract Ungulate tetraparvovirus 2 (UTV2) , formerly known as porcine hokovirus due to its discovery in Hong Kong, is closely related to a Primate tetraparvovirus (human PARV-4) and Ungulate tetraparvovirus 1 (bovine hokovirus). Until now, UTV2 was detected in European, Asian and North American countries, but its occurrence in Latin America is still unknown. This study describes the first report of UTV2 in Brazil, as well as its phylogenetic characterization. Tissue samples (lymph node, lung, liver, spleen and kidney) of 240 piglets from eight different herds (30 animals each herd) were processed for DNA extraction. UTV2 DNA was detected by PCR and the entire VP1/VP2 gene was sequenced for phylogenetic analysis. All pigs from this study displayed...

Provedor de dados: 58
Autores: Oliveira,Sílvia Dias de; Bessa,Marjo Cadó; Santos,Luciana Ruschel dos; Cardoso,Marisa Ribeiro de Itapema; Brandelli,Adriano; Canal,Cláudio Wageck.
In order to study the epidemiology of Salmonella Enteritidis outbreaks and determine the source of contamination so that a recurrence can be avoided, detailed characterization is necessary. Thus, the purpose of this study was to verify whether rep-PCR was able to discriminate among Salmonella Enteritidis isolates. Phage typing, detection of virulence genes and antimicrobial resistance testing were also associated to rep-PCR results. One hundred and two S. Enteritidis isolates from broiler carcasses, food, human, pigs, poultry-related samples, and nine isolates from other countries were genotypically typed by REP-PCR, ERIC-PCR and BOX-PCR, collectively called rep-PCR. Phage typing, detection of virulence genes and antimicrobial resistance testing were also...

Autores: Castagna,Sandra Maria Ferraz; Muller,Monika; Macagnan,Marisa; Rodenbusch,Carla Rosane; Canal,Cláudio Wageck; Cardoso,Marisa.
The aim of this study was to compare a polymerase chain reaction (PCR) method combined with selective enrichment in Rappaport-Vassiliadis broth (PCR-RVB) with standard microbiological techniques (SMT) for the generic detection of Salmonella in samples of porcine origin. Two hundred sixty eight field samples consisting of 42 sets of pooled porcine mandibular lymph nodes and tonsils, 44 samples of intestinal content, 38 pork sausage meat samples and 144 samples of feed collected from swine farms were submitted to the PCR-RVB and SMT protocols. Salmonella was detected in 54 samples using the PCR-RVB assay and in 42 samples by SMT, three of the SMT Salmonella-positive samples (one each of S. Derby, S. Panama and S. Typhimurium) being Salmonella-negative by...

Detection of virulence genes in Salmonella Enteritidis isolated from different sources
Provedor de dados: 58
Autores: Oliveira,Sílvia Dias de; Rodenbusch,Carla Rosane; Michael,Geovana B.; Cardoso,Marisa I.R.; Canal,Cláudio Wageck; Brandelli,Adriano.
The presence of three virulence genes, invA, spvR, and spvC, was determined in Salmonella Enteritidis isolated from poultry, pigs, humans and food. All isolates were positive for the invA gene, with 91.2% being positive for spvR and 90.2% for spvC. There was no significant difference in the prevalence of the virulence genes between isolates from different sources. The results indicate that there is a putative high virulence potential for the S. Enteritidis isolates characterized.
