ABSTRACT Changes in Neotropical bat taxonomy in the past two decades have caused significant shifts in our understanding of the diversity and distribution of the group. Taxonomic revisions have shown that the once widespread Platyrrhinus helleri (Peters, 1866) represented a species complex, which resulted in the elevation of Platyrrhinus helleri incarum (Thomas, 1912) to the species level for cis-Andean South America and the restriction of P. helleri to Central America and northern South America west of the Andes. Nevertheless, some studies still mention P. helleri for Brazil. Aiming to investigate if P. helleri occurs in Brazil, we collected specimens of small-sized Platyrrhinus in the Cerrado and Pantanal ecosystems, and revised vouchers in museum collections. Based on DNA sequence data and analysis of the pelage and craniodental morphology, we confirm that the only small Platyrrhinus species occurring in Cerrado and Pantanal of central Brazil corresponds to P. incarum. This is the first study to provide sequence data for Brazilian P. incarum. We also provide new records of P. incarum, extending its range by 390 km to southeast and 480 km to the east in Brazil. group Peters, Peters (Peters 1866 complex Thomas, Thomas (Thomas 1912 cisAndean cis Andean P Andes Nevertheless smallsized sized ecosystems collections morphology 39 48 186 191 3 4 18 19 1

Abstract INTRODUCTION: The Jirau hydroelectric power plant built in Rondônia state has environmental impacts that could be relevant to rabies outbreaks. METHODS: Bat populations were monitored for rabies by fluorescent antibody testing and simplified fluorescent inhibition microtesting between 2010 and 2015. RESULTS: All 1,183 bats tested negative for rabies. The prevalence of rabies antibodies was 17.5% in 1,049 bats. CONCLUSIONS: The rabies antibody dosage was not reactive in samples collected before the environmental changes, and there was a progressive increase in subsequent collections that could indicate an increase in rabies virus circulation among bats and risk of a rabies outbreak.

Introduction Hematophagous Desmodus rotundus bats play an important role in the rabies lifecycle. This study describes the hematological profile of these bats before and after experimental infection with rabies virus. Methods Cells counts were performed in a Neubauer chamber. Results The average values of erythrocytes and leucocytes counts in blood before experimental infections were 9.97 × 106mm3 and 4.80 × 103mm3, respectively. Neutrophils represented 69.9% of white blood cells and the lymphocytes represented 26.9%. Following the experimental infections, the average numbers of erythrocytes and leucocytes was 9.43 × 106mm3 and 3.98 × 103mm3, respectively. Neutrophils represented 40% of white blood cells and the lymphocytes represented 59%. Conclusions The hematological profile given in this study can serve as reference values for D. rotundus bats.

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.

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: Morcegos são um dos mais importantes reservatórios e vetores do vírus da raiva no mundo. MÉTODOS: No período entre 1998 e 2003, o Centro de Controle de Zoonoses da Cidade de São Paulo realizou o diagnóstico de raiva em 5.670 morcegos utilizando as técnicas de imunofluorescência direta e inoculação intracerebral em camundongos. Sangue foi coletado de 1.618 espécimes para pesquisa de anticorpos pela técnica de inibição de foco de fluorescência rápida. RESULTADOS: Quarenta e quatro (0,8%) morcegos foram positivos para raiva. A prevalência de anticorpos foi de 5,9% usando 0,5UI/ml como ponto de corte. Os morcegos de hábito alimentar insetívoro (69,8%) e os morcegos da espécie Molossus molossus (51,8%) representaram a maioria da amostra. Entretanto, as mais altas prevalências de anticorpos foram observadas nos morcegos 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) e Eumops perotis (1/13). A prevalência de anticorpos foi analisada por espécie, hábito alimentar e sexo. CONCLUSÕES: O expressivo nível de anticorpos associado à baixa positividade para o vírus da raiva entre os morcegos estudados indica que o vírus circula ativamente entre morcegos.

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.
