| This report describes the first preliminary characterization of porcine circovirus type 2 (PCV2) isolates from pigs affected with post-weaning multisystemic wasting syndrome (PMWS) in Brazil. Diseased pigs were examined at necropsy and by histopathology. Macroscopic and microscopic analyses revealed lesions reported to be typical of PMWS, which included, respectively, emaciation, enlargement of lymph nodes, thymus atrophy and interstitial pneumonia, and granulomatous lymphadenitis with syncytial cells, among others. Using nested polymerase chain reaction (PCR) or imunoperoxidase it was possible to detected DNA or antigen of PCV2, respectively. The PCR' s amplified fragment could be differentiated from PCV1 and PCV2 from one another by restriction fragment... |

| In a commercial herd of 1250 wild boars, 56 animals were affected by anorexia, diarrhea, and wasting. Enlargement of mesenteric lymph nodes, thickening of ileal wall, and a white-yellowish ileal content were observed in two of the four animals necropsied. Microscopically, ileal crypts showed epithelial hyperplasia, moderate decrease in goblet cell density, lymphohistiocytic infiltrate in the lamina propria, and moderate depletion with histiocytic infiltrate in Peyer's patches. Curved rod-shaped organisms within the apical cytoplasm of enterocytes were observed in both Warthin-Starry and Lawsonia intracellularis-immunostained sections. PCV2 antigen was observed in ileal Peyer's patches of 3 wild pigs. Trichuris suis nematodes were found in the cecum of the... |

| Los objetivos de este trabajo fueron la cuantificación de circovirus porcino tipo 2 (PCV2) de virus del síndrome respiratorio y reproductivo porcino (PRRSV), así como la expresión de citocinas (IL-6, IL-12, TNF-α, e IFN-γ) en nódulos linfáticos inguinales superficiales (NLIS) de cerdos afectados por el síndrome de desmedro posdestete (postweaning multisystemic wasting syndrome, PMWS) y en cerdos sanos. Con base en el diagnóstico clínico y a la cuantificación de PCV2 por hibridación in situ y qRT-PCR, los cerdos se distribuyeron en tres grupos: 1) PMWS, cerdos con signos de desmedro y con cargas virales altas en NLIS (n = 4); 2) con desmedro sin PMWS, cerdos con signos de desmedro y cargas virales de intermedias a bajas en NLIS (n = 3); y 3) cerdos sanos,... |

| ABSTRACT: Modern swine production employs a high degree of technology and is organized in various production stages, in which reproduction is one of the most significant. However, reproductive losses associated to fetal death are still high. Fetal losses, including fetal mummification, may occur at a rate below 1.5% in a sound herd. The causes of fetal death can be very diverse, and include various infectious agents. Therefore, investigating the causes of fetal losses is important in the decision-making process related to the control and prophylaxis of the herd. The goal of this study was to carry out a molecular survey, analyzing porcine circovirus 2 (PCV2), porcine parvovirus (PPV), and pathogenic Leptospira as potential agents related to fetal death in... |

| A circovirose suína é uma doença infecciosa cujo agente é o circovírus suíno tipo 2 ou PCV2 e é considerada uma das principais enfermidades da suinocultura. A circovirose ou doença associada ao PCV2 (PCVAD ou PCVD), por ser causada por um agente imunossupressor, deixa os suínos mais vulneráveis a outros agentes de doenças respiratórias e entéricas (CIACCI-ZANELLA, 2015). Seu controle é realizado por meio da correção de fatores de risco e utilização de vacinas (ZANELLA; MORÉS et al. 2016). |
