ABSTRACT.- Donin D.G., Leme R.A., Alfieri A.F., Alberton G.C. & Alfieri A.A. 2015. Molecular survey of porcine teschovirus, porcine sapelovirus, and enterovirus G in captive wild boars (Sus scrofa scrofa) of Paraná state, Brazil. Pesquisa Veterinária Brasileira 35(5):403-408. Laboratório de Virologia Animal, Departamento de Medicina Veterinária Preventiva, Universidade Estadual de Londrina, Rodovia Celso Garcia Cid, Campus Universitário, Cx. Postal 10011, Londrina, PR 86057-970, Brazil. E-mail: alfieri@uel.br Porcine teschovirus (PTV), porcine sapelovirus (PSV), and enterovirus G (EV-G) are infectious agents specific to pig host species that are endemically spread worldwide. This study aimed to investigate the natural infection by these porcine enteric picornaviruses in wild boars (Sus scrofa scrofa) of Paraná state, Brazil, and to evaluate peccaries (Pecari tajacu and Tayassu pecari) as alternative host species for these viruses. Fecal samples (n=36) from asymptomatic wild boars (n=22) with ages ranging from 2 to 7 months old (young, n=14) and 2 to 4 years old (adult, n=8) and from peccaries (6 to 8 months old, n=14) were collected from a farm and a zoo, respectively, both located in Paraná state. Reverse transcription-polymerase chain reaction (RT-PCR) and nested-PCR (n-PCR) assays targeting the 5’non-translated region of the virus genome were used for screening the viruses. Porcine enteric picornaviruses were detected in 12 out of the 22 wild boar fecal samples. According to each of the viruses, EV-G was most frequently (11/22, 50%) detected, followed by PTV (10/22, 45.5%) and PSV (4/22, 18.2%). Regarding the age groups, young wild boars were more frequently (9/14, 64.3%) infected with PTV, PSV, and EV-G than adult animals (3/8, 37.4%). One n-PCR amplified product for each of the viruses was submitted to sequencing analysis and the nucleotide sequences were compared with the related viruses, which showed similarities varying from 97.7% to 100% for PTV, 92.4% to 96.2% for PSV, and 87.1% to 100% for EV-G. Peccaries tested negative for the viruses and in this study they did not represent infection reservoirs. This study is the first to report the molecular detection of PTV, PSV, and EV-G from captive wild boars in a South American country and the first to screen peccaries as alternative host species for porcine enteric picornavirus.

E-mail: alfieri@uel.br Teschovírus suíno (PTV), sapelovírus suíno (PSV) e enterovírus G (EV-G) são agentes infecciosos específicos da espécie suína que estão endemicamente disseminados em todo o mundo. O objetivo deste estudo foi investigar a infecção natural por estes picornavírus entéricos suínos em javalis (Sus scrofa scrofa) do estado do Paraná, Brasil e avaliar pecaris (Pecari tajacu e Tayassu pecari) como hospedeiros alternativos para estes vírus. Amostras fecais (n=36) de javalis assintomáticos (n=22) com idades de 2 a 7 meses (jovens, n=14) e 2 a 4 anos (adultos, n=8) e de pecaris (6 a 8 meses de idade, n=14) foram coletadas em um cativeiro e zoológico, respectivamente, ambos localizados no estado do Paraná. A transcrição reversa seguida por reações da polimerase em cadeia (RT-PCR) e nested-PCR com alvo na região 5’-não traduzida do genoma viral foram utilizadas para a identificação dos vírus. Picornavírus entéricos suínos foram detectados em 12 das 22 amostras fecais de javalis. De acordo com cada um dos vírus, EV-G foi mais frequentemente (11/22, 50%) detectado, seguido pelo PTV (10/22; 45,5%) e PSV (4/22; 18,2%). Considerando os grupos de idade, javalis jovens foram mais frequentemente (9/14; 64,3%) infectados com PTV, PSV e EV-G do que os javalis adultos (3/8; 37,4%). Um produto amplificado na nested-PCR para cada um dos vírus foi submetido à análise de sequenciamento e as sequências de nucleotídeos foram comparadas com vírus relacionados, o que mostrou que as similaridades variaram entre 97,7% a 100% para o PTV, 92,4% a 96,2% para o PSV e 87,1% a 100% para o EV-G. Os pecaris foram negativos para as viroses investigadas e neste estudo não se apresentaram como hospedeiros alternativos para as infecções. Este estudo é o primeiro a relatar a detecção molecular de PTV, PSV e EV-G em javalis de cativeiro de um país da América Latina e o primeiro a avaliar pecaris como espécie hospedeira alternativa para picornavírus entéricos suínos.

E-mail: ivansantos7@hotmail.com Considering the importance of umbilical cord blood as a potential source of stem cell and, on the other hand, the use of the domestic swine (Sus scrofa) as a useful model for biomedical research in regenerative medicine and aiming to contribute about the quantification of lymphocyte subsets in umbilical cord blood and peripheral blood of newborn piglets, this study aimed to quantify CD4+, CD5+ and CD8+ cells from umbilical cord blood and peripheral blood from pigs at term blood samples. Were analyzed samples of the umbilical cord blood and peripheral of 48 piglets of Topigs lineage, from healthy mothers, artificially inseminated and natural birth. Blood samples were collected from the umbilical cord at birth, by the umbilical vein, and peripheral blood by venous sinus retro-ophthalmic. The immunological measurements of CD4+, CD5+ and CD8+ were obtained by flow cytometry. The relative average values for the CD4+, CD5+ e CD8+ counts in umbilical cord blood and peripheral blood of newborn piglets were inferior to those reported for peripheral blood in adult pigs, suggesting immunological immaturity. The ratio CD4+:CD8+ in umbilical cord blood (3.2±1.2%) and peripheral blood (3.2±1.7%) showed a predominance of TCD4+ over TCD8+. The percentage of CD4+ and CD8+ cells was 1.37±0.86% and 1.15±0.57%, respectively, in umbilical cord blood and peripheral blood.

Analisaram-se as amostras do sangue do cordão umbilical e periférico de 48 leitões de linhagem Topigs, provenientes de porcas hígidas, inseminadas artificialmente e de parto natural. Foram coletadas amostras de sangue do cordão umbilical e periférico no momento do nascimento, por meio de venopunção da veia umbilical e seio venoso retro-oftálmico, respectivamente. As quantificações imunofenotípicas de células CD4+, CD5+ e CD8+ foram obtidas por citometria de fluxo. Os valores médios obtidos para as contagens das células CD4+, CD5+ e CD8+ do sangue do cordão umbilical e periférico apresentaram-se inferiores aos reportados para o sangue periférico de suínos adultos, sugerindo um componente imunológico imaturo. A proporção CD4+:CD8+ obtida no sangue do cordão umbilical (3,2±1,2%) e no sangue periférico (3,2±1,7%) ilustrou a predominância dos linfócitos TCD4+ com relação aos TCD8+. A quantidade relativa de células CD4+ e CD8+ no sangue do cordão umbilical e periférico foi de 1,37±0,86% e 1,15±0,57%, respectivamente.

E-mail: savasco@usp.br The diagnostic value of the cutaneous allergic response to tuberculin in piglets experimentally sensitized intramuscularly with the oily suspensions of heat inactivated M. bovis or M. avium was investigated. Ninety-one animals were used and divided into four groups: groups A and B were formed each with 25 individuals, and groups C and D, with 21 and 20 individuals, respectively, balancing the characteristics of race, ancestry, age and sex. At the age of 30 days, all the animals were submitted to the screening test with the use of M. bovis PPD, by the intradermal route at the base of the ear and no reaction was detected. Sixty days after the screening tuberculin test, animals of the group A were injected intramuscularly with 0.5 mL of oily suspension of M. avium D4 strain; animals of the group B received 0.5 mL of an oily suspension of M. bovis, AN5 strain; group C (control I) received 0.5 mL of an oily adjuvant; and the individuals of the group D (control II) received 0.5 mL of saline solution. Following 30 days of sensitization, comparative skin reactions were measured by the variation in skin thickness with a caliper at 0h, 24h, 48h an 72h after applications of tuberculins. In the comparative test measured at 48 or 72h, the reaction was considered negative when the difference of the reactions between bovine PPD and avian PPD was less than 6.7 mm; suspected or inconclusive, when the difference stood in the range of 6.7 to 7.5 mm; and positive according to the type of PPD, considering tuberculosis the M. bovis PPD and mycobacteriosis the M. avium PPD, when the difference of the reaction was greater than 7.5 mm.

E-mail: ecco@vet.ufmg.br The aim of this paper is to describe the clinical, epidemiological, pathological, bacteriological and immunohistochemical aspects of a pneumonia outbreak in a wild pig farm in the Distrito Federal, Brazil. Ninety wild pigs died in a period of five months, and 63 of these had pulmonary lesions. Clinically, the pigs presented reduced growth rate, anorexia, lethargy, cough and dyspnea, especially after they were moved. High body temperature (40oC in average) was verified in some animals. Auscultation revealed moderate pulmonary crepitation and stertors. Pulmonary gross lesions were typical of lobular bronchopneumonia. Lung lesions were characterized by ventral-cranial consolidation in the majority of the cases. The color of affected pulmonary areas varied from diffuse dark red to mosaic pattern (dark red lobule intercalate by grayish lobule) or diffusely grayish. The majority of the lungs had mucopurulent exsudate in the bronchial lumen that also drained from the parenchyma cut surface. Upon microscopy, the changes were characterized by purulent and histiocytic bronchopneumonia with necrotic foci. In some animals, there was BALT hyperplasia associated with perivascular and peribronchial plasma cells and lymphocytes infiltration in most of these cases. Bordetella bronchiseptica and Streptococcus spp. were the most frequently isolated bacteria. Immunohistochemistry evaluation demonstrated Mycoplasma hyopneumoniae on the luminal surface of bronchial and bronchiolar epithelial cells, and the DNA of bacteria was detected by PCR. This is the first report of bronchopneumonia in wild boars associated with M. hyopneumoniae infection.

Enhanced lymph nodes and spleens, ascites, hydrothorax, and non collapsed lungs were the principal gross lesions. Varying degrees of lymphohistiocytic infiltrates in lymph nodes, spleen, and intestines were the most significant microscopic changes. Although a total of 26 animals had showed clinical and pathological findings consistent with the disease, only in 11 of them it was possible to confirm a PMWS diagnosis through the association of specific lesions in lymphoid tissues with the presence of the viral antigen detected by immunohistochemistry. These findings were similar to those reported in the swine disease.
