“…The authors concluded that puppies should receive a second vaccine dose as a complement of primevaccination to increase the antibodies titers. Similar results were observed in other studies (ALMEIDA et al, 1997;SEGHAIER et al, 1999;SILVA et al, 2009), reinforcing the need for complementation of primary vaccination in those animals receiving the first anti-RABV vaccine.…”

The present study investigated the frequency and magnitude of neutralizing antibodies to rabies virus (RABV) in dogs with and without historic of vaccination in Santa Maria/RS. Group A included serum samples from 440 dogs with recent historic of vaccination against rabies, obtained during the 2015 rabies vaccination campaign. Group B included 300 serum samples from dogs submitted to the Veterinary Hospital of the Universidade Federal de Santa Maria in 2015, whose historic of rabies vaccination was unknown. Serum samples were submitted to the rapid fluorescent focus inhibition test (RFFIT) to detect neutralizing antibodies against RABV. In group A, 70.6% (310/440) of the samples had neutralizing antibody titers ≥0.5 international units per milliliter (IU mL-1), considered an indicative of protection against rabies by the World Health Organization. However, approximately 30% of the dogs did not contain antibodies in adequate levels. In group B, 42.3% (127/300) of the samples contained neutralizing antibody titers ≥0.5IU mL-1 and 57.7% (173/300) were negative or contained titers below of the value considered immunized. These results demonstrate that an important proportion of vaccinated dogs (~30%) did not develop adequate antibody levels, mainly those receiving a single vaccine dose. Serologic testing of animals with unknown historic of vaccination revealed relatively low vaccine coverage in the general dog population. Thus, reformulation of immunization strategies - especially the recommendation of a boost vaccination 30 days after the primary dose - and extension of vaccination campaigns are necessary to reach adequate levels and coverage of immunity against RABV in the canine population.

“…Segundo esses autores, já foram isolados vírus rábico em outros animais como raposas (Dusicyon vetulus), demonstrando que esse animal no Nordeste é considerado um reservatório silvestre importante do vírus da raiva. Outras variantes já foram isoladas em saguis no Ceará (18) e em outra espécie de raposa (Pseudoalopex vetulus) na Paraíba (19) , enfatizando que esses animais também podem estar envolvidos na manutenção da doença (17,20) . Deve-se considerar que os dados de outros estados comentados anteriormente são apenas estimativas e não dados oficiais, ou seja, aqueles que são notificados ao Serviço Oficial de Defesa Sanitária Animal, e que, no Brasil, esses dados oficiais são registrados em publicações oficiais no site do Ministério da Agricultura, Pecuária e Abastecimento -MAPA.…”

Distribuição Espaço-Temporal Dos Diagnósticos Laboratoriais Da Raiva Animal

Resumo:A raiva é uma enfermidade infectocontagiosa que afeta mamíferos, inclusive o homem. Estima-se que a raiva dos herbívoros seja responsável por enormes prejuízos econômicos na América Latina. O morcego hematófago Desmodus rotundus é o principal transmissor do vírus rábico (VR). Este estudo teve como objetivo avaliar a evolução do diagnóstico laboratorial para raiva animal em cinco espécies animais, na série cronológica 1990-2010, na microrregião Quirinópolis, Goiás, Brasil. Para avaliação da distribuição dos casos diagnosticados foram utilizados resultados de diagnóstico laboratorial, realizados pelo Laboratório de Diagnóstico da Agência Goiana de Defesa Agropecuária. A partir destes, foi construído um banco de dados com as variáveis: município de origem do animal, resultado, mês e ano. Das 116 amostras analisadas, 9% (10) foram positivas para oVR e 91% (106) negativas. Todos os resultados positivos foram provenientes de bovinos. Dentre os municípios da microrregião, Itarumã apresentou maior número de casos positivos e Caçu enviou mais amostras. Houve tendência de aumento no envio de amostras e no número de exames laboratoriais. Também houve tendência ao aumento de diagnósticos positivos. Amostras da espécie bovina foram as mais analisadas, seguida de morcegos hematófagos. Em relação à época do ano, foram observados mais casos positivos no período da seca. Palavras-chave: Animais domésticos; epidemiologia; quirópteros; vírus rábico. Abstract:Rabies is an infectious contagious disease that affects mammals, including humans.

“…Na ordem Carnivora, destacam-se as famílias Canidea (cães, raposas etc), Procyonidae (guaxinim), Mustelidea (gambá) e Herpestidae (mangosta) (KOTAIT et al, 2007). Os reservatórios domésticos mais importantes para a raiva humana na América Latina são os cães e os animais selvagens considerados reservatórios nessa região que são as raposas e os morcegos (SILVA et al, 2009;MASCARENHAS et al, 2009). A infecção é fatal quando o infectado pelo VR não recebe profilaxia pós-exposição adequada.…”

The rabies is a zoonotic infection that attacks the central nervous system, being caused by a virus of RNA belonging to the Lyssavirus genus. The present study aimed to gather information about the importance of rabies virus (VR) control, correlating with its geographical distribution, biological cycle, pathogenesis and prophylactic measures. This is a review study in which the databases Medline/Pubmed, Lilacs, Scielo, Science Direct, thesis and dissertation bank of public universities and the national and international health committees were used. We analyzed 105 materials, of which 52 were included in this study, those that did not have relevant aspects about the proposed theme, were excluded. Rabies has a worldwide distribution, where its mortality reaches almost 100%. Therefore, permanent surveillance of the different components of the RV transmission chain is essential, in addition vaccination of domestic animals (dogs and cats) and post-exposure prophylaxis should be well performed to promote better prevention against this virus and to prevent possible development of this disease.
