| Abstract Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus disease, a complex multisystem syndrome in domestic pigs. Despite the significant economic losses caused by porcine circovirus disease, the mechanisms of pathogenesis underlying the clinical findings remain largely unclear. As various reports have highlighted the potential key role of vascular lesions in the pathogenesis of porcine circovirus disease, the aim of this work was to investigate effects of PCV2 infection on vascular endothelial cells, focusing on cell viability and expression of adhesion/junction molecules. PCV2 infection reduced endothelial cell viability, while viral infection did not affected the viability of several other classical cell lines.... |

| The genomic DNA of thirty strains of Aujeszky's disease virus (ADV) isolated in the South and Southeast regions of Brazil from 1982 to 1996 were characterized by restriction endonuclease analysis with BamHI. Twenty seven strains were isolated from pigs, 1 from cattle, 1 from cat and 1 from dog. Using a systematization previously described, the 30 ADV strains could be classified as genomic types I (n = 2) and II (n = 28). Genomic type III was not observed. In this first study of genomic type characterization of brazilian ADV strains, we could demonstrate the occurence in Brazil of the genomic types I and II, with a large predominance of genomic type II. |

| Diarrhoea among growing and finishing pigs is an important problem in many herds. The prevalence of L. intracellularis, B. pilosicoli, B. hyodysenteriae, Salmonella spp., enterotoxigenic E. coli, Trichuris suis and the occurrence of mixed infection were investigated. Fecal samples for forty-six herds with diarrhea or a history of diarrhea were randomly collected in Minas Gerais state, Brazil. The enteric pathogens were detected by culture (E. coli and Salmonella sp.), PCR (L. intracellularis and Brachyspira spp.) and eggs counts (T. suis). The overall herd prevalence of L. intracellularis, Salmonella enterica serotype Typhimurium and enterotoxigenic E. coli were 19.56%, 6.52%, 10.86% respectively. Mixed infection was diagnosed in 30.43% of herds, and L.... |

| There is no information about evidence of hepatitis E virus (HEV) infection in swines in Central Brazil. In order to assess if HEV circulates in swines of the State of Mato Grosso, Central Brazil, a seroprevalence study was conducted including pigs from 17 farms, corresponding to 13 counties. The animals were randomly chosen among pigs arriving to two slaughterhouses between December 2002 and February 2003. Serum samples were collected and tested for IgG antibodies against HEV (anti-HEV) by enzyme immunoassay (EIA). This EIA uses two HEV recombinant proteins as antigens, a mosaic protein (MP-II) and a protein containing region 452-617 of the ORF2 of the HEV Burma strain as coating antigens. 211 out of 260 pigs (81.2%; 95CI = 75.7%, 85.6%) were anti-HEV... |

| ABSTRACT Corn is one of the primary ingredients in swine diets, but there is a variation in its chemical composition and metabolizable energy (ME) content. Therefore, faster methods are required that can determine more accurate ME values to improve piglet diets. This study determined and predicted the ME of corn from first and second harvests for piglets. Two experiments were conducted to determine the ME values for 18 corn batches, evaluating corn from first and second harvests. The corn batches were analysed to determine the concentration of dry matter (DM), starch (ST), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), ether extract (EE), ash, calcium (Ca), phosphorus (P) and gross energy (GE). To determine the ME values, 40... |

| Clostridium perfringens is a gram-positive, anaerobic, fermentative, spore-forming bacillus that may be found in the environment but is more commonly found as part of the microbiota of humans and animals. The bacterium is considered a common enteric pathogen; however, the pathogenesis and predisposing factors of the disease can differ among species. Therefore, specific studies are necessary for understanding the role of this pathogen, how to diagnose it and which control measures are applicable. The aim of this paper is to review the current knowledge regarding C. perfringens infections in pigs, horses and broiler chickens |

| ABSTRACT: This study investigated the occurrence of antibodies for BVDV-1 in swine herds located in the region of Mossoró city of the state of Rio Grande do Norte, Brazil. A sample size of 412 animals was estimated assuming unknown prevalence (set at 50%). Virus neutralization assay was used to the detect the presence of antibodies for BVDV-1 and the results found were analysed using multivariable logistic regression model. The obtained prevalence was 4% at animal level and 45% at the animal and herd level. The titers were highly variable between animals and within farms. The multivariable logistic regression analysis showed an association between being housed outside and exposure to BVDV-1 (OR=0.24, 95% CI:0.06, 0.96, P=0.04). Highly correlated data and... |

| Deep litter systems represent low cost alternatives to raise growing-finishing pigs, reducing slurry accumulation, although pig's thermal comfort may be negatively affected by the heat produced inside the litter. This study compared environmental and performance parameters for growing-finishing pigs raised on deep litter systems having distinct depths and on solid floor. The experiment was conducted in a region of temperate climate of Brazil, comparing three treatments: litter having rice husk 0.5m (T1); and 0.25m deep (T2); and solid concrete floor (T3). The first litter was used in two lots and replaced by a second litter used in other two lots, during 52 weeks. Each lot included five pigs in a 7m² pen, from 60 to 145 d of age. Environmental parameters... |

| The purpose of this study was to evaluate the effects of a dietary added formaldehyde-propionic acid blend on feed enterobacteria counts and on growing pig performance and fecal formaldehyde excretion. Forty pigs (34.2±1.8kg BW) were used in a randomized complete block design experiment with four treatments, five replications per treatment and two animals per experimental unit (pen). The treatments were: 0.0, 1.0, 2.0, and 3.0g of blend kg-1 of feed. No effects (P>0.05) of dietary added blend levels were observed on average daily gain, average daily feed intake and feed:gain ratio during 1 to 14 and 1 to 28 days of experiment. Increasing dietary levels of blend reduced quadratically (P<0.01) total Enterobacteriaceae counts on 1st and 14th day after... |

| ABSTRACT: To assess the success of a segregated medicated early weaning protocol for elimination of Actinobacillus pleuropneumoniae, ten consecutive batches of 100 pigs per batch weaned at 7-9 days of age were monitored at 21-22 weeks of age looking for presence of productive cough, presence of antibodies against the agent and pleuropneumonia-compatible lung lesions at slaughter. Also, whole tonsils were processed for A. pleuropneumoniae identification by both bacteriological isolation and nested-PCR using a direct method. Positive serological test (1.4%) and PCR (3.5%) results, suggested that A. pleuropneumoniae could not be eradicated in all batches, even using segregated medicated early weaning protocol. |

| Clostridium perfringens is an anaerobic Gram-positive bacterium known as common pathogen for humans, for domestic and wildlife animals. Although infections caused by C. perfringens type C and A in swine are well studied, just a few reports describe the genetic relationship among strains in the epidemiological chain of swine clostridioses, as well as the presence of the microorganism in the slaughterhouses. The aim of the present study was to isolate C. perfringens from feces and carcasses from swine slaughterhouses, characterize the strains in relation to the presence of enterotoxin, alpha, beta, epsilon, iota and beta-2 toxins genes, using polymerase chain reaction (PCR) and comparing strains by means of Pulsed field gel electrophoresis (PFGE).... |

| ABSTRACT: Zeolites are minerals that have intriguing properties such as water absorption, ion adsorption and cation exchange capacity. There are approximately 80 species of natural zeolites recognized and hundreds of artificial zeolites, which have been researched in several fields. Due to their chemical characteristics, zeolites have great potential for use in animal production, especially in poultry and swine farms, as food additives, litter amendment and treatment of residues, with direct and indirect effects on performance, yield and quality of carcass, ambience of farm sheds and reduction of environmental pollution. |
