Rabies transmitted by vampire bats was diagnosed in pigs with paralysis of the pelvic limbs. Diffuse non-suppurative encephalomyelitis, affecting mainly the spinal cord, was observed histologically. Despite the various diagnosis of rabies in pigs this is the first report of clinical signs and pathology of rabies transmitted by vampire bats.
526Pesq. Vet. Bras. 29(7): 526-532, julho 2009 RESUMO.-A tuberculose é uma enfermidade infecciosa, de distribuição mundial, provocada por micobactérias patogênicas, que afeta o homem e diversas espécies de mamíferos. Visando determinar a prevalência da Tuberculose Caprina e identificar fatores de risco associados à infecção foram tuberculinizados, através do Teste Tuberculínico Comparado (TCC), 1.866 caprinos de diferentes raças e idades, oriundas de 84 propriedades localizadas na microrregião de Monteiro, Estado da Paraíba, Brasil. A interpretação do TCC foi aferida pelo cálculo da diferença obtida entre as cutimetrias correspondentes às respectivas tuberculinas, antes e 72 horas após a inoculação: negativa, quando PPD bovina for menor que a aviária ou maior em até 1,8mm; suspeita ou inconclusiva, reação à PPD bovina maior que a aviária entre 1,9 e 2,4mm; positiva, reação à PPD bovina maior ou igual a aviária em 2,5mm. Das cabras submetidas ao TCC, 0,47% (9/1866), reagiram positivamente (IC 95% = 0,23-0,94% Tuberculosis is an infectious disease of world wide distribution caused by pathogenic mycobacteria that affect humans and several mammals species. In order to determine the prevalence of tuberculosis in goats and to identify risk factors associated with infection, 1,866 goats of different breeds and ages from 84 herds in the microregion of Monteiro, State of Paraíba, Northeast Brazil, were tuberculinized by the Comparative Cervical Test (CCT). Interpretation of the CCT was checked by calculation of the difference obtained between skin measures correspondent to respective tuberculins, before and 72 hours after inoculation: negative, when bovine PPD is smaller than avian PPD or larger in up to 1.8mm; suspicious or inconclusive, reaction to bovine PPD larger than avian PPD between 1.9 and 2.4mm; positive, reaction to bovine PPD larger than or equal to avian PPD in 2.5mm. From goats submitted to CCT, 0.47% (9/1866) reacted positively (95% CI = 0.23%-0.94%). The prevalence of positive herds to caprine tuberculosis was 10.71% (95% CI = 5.02-19.37%). When submitted to necropsy and histopathologic examination, a positive goat at tuberculin test presented tuberculosis-like lesions. The presence of Acid-Alcohol Resistant Bacilli (BAAR) was also detected by direct bacterioscopy; in relation to herd size, herds with larger number of animals (>25) with high incidence of the disease, and presence of the infection was evidenced in properties that raised cattle in association with goats and did not carry out tuberculin tests in cattle.INDEX TERMS: Caprine tuberculosis, prevalence, tuberculin test.
To determine the presence of rabies virus in the parotid salivary glands, 12 road-killed rabies-positive hoary foxes (Pseudoalopex vetulus) were tested by using the fluorescent antibody test (FAT) and mouse inoculation test (MIT). All 12 parotid salivary glands were positive for both tests, although in some cases several passages were required. The findings of this study support the importance of the hoary fox as rabies reservoir in the sem-iarid region of Paraíba State, Northeastern Brazil.
The present report describes the first case of vesicular stomatitis in the State of Paraíba, Brazil. Records from the Official Veterinary Services of the State of Paraíba were analyzed while responding to a suspected case of vesicular disease at a property (property I) in the municipality of Pombal in which the cattle showed clinical signs and lesions of vesicular disease. Surveillance in the surrounding area revealed similar lesions in cattle at two other properties (II and III). Based on these events, the suspicion was considered well founded, and samples were collected for evaluation at the National Agricultural Laboratory of the State of Pará. The property was interdicted, and those located within a 3 km radius (perifocal) from the focus were inspected. At property I, 42.86% (6/14) of the cattle showed vesicular disease lesions characterized by intense sialorrhea, ruptured oral vesicles, epithelial detachment of the tongue and muzzle, and vesicular lesions in the udder and interdigital space. Similar lesions were detected in cattle at properties II and III, affecting 80.95% (34/42) and 11.54% (3/26) of the animals, respectively. Tissue samples collected from the three properties were positive for the vesicular stomatitis virus (Indiana 3 subtype). The properties were monitored for 21 days after the last infected animal was cured, and afterwards, the three properties were released. Key words: Vesicular stomatitis, vesicular disease, cattle, State of Paraíba ResumoO presente trabalho teve como objetivo relatar o primeiro diagnóstico de Estomatite Vesicular no Estado da Paraíba. Foram analisados os documentos produzidos pelo Serviço Veterinário Oficial do Estado da Paraíba durante o atendimento de uma notificação de suspeita de doença vesicular em uma propriedade (propriedade I) do município de Pombal em que bovinos apresentavam sinais clínicos e lesões compatíveis com doença vesicular. Durante a vigilância das propriedades vizinhas, em outras duas propriedades (II e III) foram encontradas lesões similares. Diante desse quadro, a suspeita foi considerada fundamentada e foi feita a colheita de material para diagnóstico no Laboratório Nacional Agropecuário no Estado do Pará (LANAGRO-PA), interdição da propriedade e investigação das propriedades de um raio de
O objetivo do presente trabalho foi determinar a ocorrência de anticorpos anti Brucella abortus, anti Brucella canis e anti Leptospira spp. em raposas (Pseudalopex vetulus). Para tanto, foram utilizadas 60 raposas atropeladas em rodovias no semiárido da Paraíba, Nordeste do Brasil. Para a detecção de anticorpos anti Brucella abortus, o teste do antígeno acidificado tamponado (AAT) foi empregado como teste de triagem, e a prova do 2-mercaptoetanol foi empregada como método confirmatório. Para o diagnóstico sorológico das infecções por Brucella canis e Leptospira spp., foram utilizados os testes de imunodifusão em gel de agar (IDGA) e soroaglutinação microscópica, respectivamente. Todas as amostras foram negativas na pesquisa de anticorpos anti Brucella canis e anti Leptospira spp. Das 60 raposas testadas, 16 (26,6%) foram positivas para anticorpos anti Brucella abortus no teste de AAT, e quatro (6,7%) amostras foram confirmadas no teste de 2-mercaptoetanol, sendo duas amostras com título 100 e duas com título 50.
The rabies virus propagates through several epidemiological cycles, which makes it difficult to control and predict. Thus, this study was structured with the aim of establishing the geospatial characterization of bat shelters in different semi-arid mesoregions of the state of Paraíba, Northeastern region of Brazil. Data provided by the Secretaria de Estado do Desenvolvimento da Agropecuária e da Pesca da Paraíba (SEDAP-PB), from 2007 to 2015 and data from digital platforms were used. The geographic representation was produced using the software QGIS 2.16.0 - Nodebo. To verify virus circulation sites, buffers were plotted within a 10-km radius from the registered shelters and rabies incidence sites in the state. A registry of 93 shelters in the period between 2007 and 2015 were distributed in 22 municipalities and 15 microregions. All mesoregions were represented, though 47.31% of the bat shelters were located in Agreste Paraibano. Of the total registered shelters, 66 (71%) are classified as artificial, and 27 (29%) as natural. The underreporting of rabies occurrences reveals the need to improve the registration of hematophagous bat shelters, specifically those for the D. rotundus species.
