Albinism in Carollia perspicillata (Chiroptera; Phyllostomidae), in the state of Rondônia, Brazil. A brief review of albinism in bats

Albinism is a phenomenon that is not very common in bats. In the literature, sixty-seven bat species with this mutation have been reported. The purpose of this paper is to report a case of complete albinism in Carollia perspicillata. A young male albino bat was captured in a culvert under the BR 364 highway, located within an anthropogenic area in the district of Caiçara, municipality of Porto Velho, in the northern Brazilian state of Rondônia. The animal was apparently well integrated into the group, healthy and of normal size for the species. A brief review of albinism in bats is also provided

A proposta desse artigo é relatar um caso de albinismo completo em Carollia perspicillata. Um morcego, jovem, macho, albino foi capturado em um bueiro sob a rodovia BR364, localizado em uma área antropogênica na Vila de Caiçara, município de Porto Velho, no estado de Rondônia. O animal estava aparentemente bem integrado ao grupo, saudável e de tamanho normal para a espécie. Um breve resumo de albinismo em morcegos é apresentado.

Rabies diagnosis and serology in bats from the State of São Paulo, Brazil

INTRODUCTION: Bats are one of the most important reservoirs and vectors of the rabies virus in the world. METHODS: From 1988 to 2003, the Zoonosis Control Center in São Paulo City performed rabies diagnosis on 5,670 bats by direct immunofluorescent test and mouse inoculation test. Blood samples were collected from 1,618 bats and the sera were analyzed using the rapid fluorescent focus inhibition test to confirm rabies antibodies. RESULTS: Forty-four (0.8%) bats were positive for rabies. The prevalence of rabies antibodies was 5.9% using 0.5IU/ml as a cutoff. Insectivorous bats (69.8%) and bats of the species Molossus molossus (51.8%) constituted the majority of the sample; however, the highest prevalence of antibodies were observed in Glossophaga soricina (14/133), Histiotus velatus (16/60), Desmodus rotundus (8/66), Artibeus lituratus (5/54), Nyctinomops macrotis (3/23), Tadarida brasiliensis (3/48), Carollia perspicillata (3/9), Eumops auripendulus (2/30), Nyctinomops laticaudatus (2/16), Sturnira lilium (2/17) and Eumops perotis (1/13). The prevalence of rabies antibodies was analyzed by species, food preference and sex. CONCLUSIONS: The expressive levels of antibodies associated with the low virus positivity verified in these bats indicate that rabies virus circulates actively among them

Avaliação da imunidade ativa de cães primovacinados (Fuenzalida & Palácios) no intervalo de campanhas anuais de vacinação contra a raiva no município de Botucatu/SP

Rabies is a worldwide zoonoses, with fatal prognosis in almost 100% of the cases. Rabies control in companion animals by mass vaccination must culminate in the break of the epidemiological link. The aim of the present study was to evaluate the active immunity of primo vaccinated dogs in urban area of Botucatu/SP, using 576 serum samples, collected in five different moments. The technique used to quantify antibodies titers against rabid virus was rapid fluorescent focus inhibition test. Results conclude that from all dogs, 54.7% had protector titer after 12 months.A Raiva é uma zoonose de distribuição mundial, com prognóstico fatal em quase 100% dos casos. O controle da Raiva em animais de companhia por meio da vacinação em massa deve culminar na quebra do elo epidemiológico. Com o objetivo de avaliar a imunidade ativa de cães primovacinados na zona urbana do município de Botucatu/SP, foram analisados 576 soros, colhidos em cinco momentos diferentes. A técnica utilizada para quantificação dos títulos de anticorpos antirrábicos neutralizantes foi à inibição de focos de fluorescência rápida. Os resultados permitiram concluir que do total dos cães, apenas 54,7% tiveram título protetor após 12 meses

First report of rabies infection in bats, Molossus molossus, Molossops neglectus and Myotis riparius in the city of São Paulo, State of São Paulo, southeastern Brazil Primeiro relato de infecção de vírus da raiva em morcegos, Molossus molossus, Molossops neglectus e Myotis riparius na cidade de São Paulo, Estado de São Paulo

INTRODUCTION: This paper presents the first report of rabies in three bat species, Molossus molossus, Molossops neglectus and Myotis riparius in the city of São Paulo, Brazil. METHODS: Bats were diagnosed as positive for rabies using the fluorescent antibody test and mouse inoculation test. The isolates were characterized antigenically using a panel of eight monoclonal antibodies. The samples were also genetically analyzed by partial sequencing of the portion of nucleoprotein gene between positions 1157 and 1445nt. RESULTS: Analysis of the results verified that the sample isolated from the species M. molossus presented antigenic variant 6, while the other two samples showed a different profile from that established in the panel, one not previously reported in the literature. The results of genetic analysis revealed that the M. molossus sample segregated with Lasiurus sp. isolates, M. neglectus segregated with a subgroup of Eptesicus furinalis isolates and the Myotis riparius sample segregated with Myotis sp. isolates. CONCLUSIONS: The cases reported in this paper emphasize the need for clarification of the circumstances in which cases of rabies in wildlife occur, principally in urban areas.INTRODUÇÃO: Esse trabalho apresenta o primeiro registro de raiva em três espécies de morcegos: Molossus molossus, Molossops neglectus e Myotis riparius na Cidade de São Paulo, Brasil. MÉTODOS: Os morcegos foram diagnosticados como positivos para raiva usando as técnicas padrão de imunofluorescência direta e o teste de inoculação em camundongo. Os isolados foram caracterizados antigenicamente usando um painel de oito anticorpos monoclonais (CDC/Atlanta/USA). As amostras também foram analisadas geneticamente por sequenciamento parcial do gene da nucleoproteína entre as posições 1157 e 1445nt. RESULTADOS: O resultado das análises mostrou que as amostras isoladas da espécie M. molossus apresentou variante antigênica 6, enquanto as outras duas amostras mostraram um perfil diferente daquele estabelecido no painel e ainda não registrado em literatura. Os resultados da analise genética revelaram que a amostra de M. molossus segrega com isolados de Lasiurus sp., M. neglectus segrega com o isolado do subgrupo de Eptesicus furinalis e uma amostra de M. riparius segrega com isolados de Myotis sp. CONCLUSÕES: Os casos relatados neste estudo enfatizam a necessidade do esclarecimento da ocorrência de casos de raiva em morcegos, principalmente em áreas urbanas
