“…A large number of positive bats and also rabid stray dogs and cats are found in many places around the City, and could be unnoticed because of underreporting. These observations are in agreement with those of Silva et al 9 . Despite this not being the focus of this study, the necessity for the effective control of stray animals in the urban environment is evident.…”

“…In the City of Rio de Janeiro, a larger study with more samples is required in order to reveal the true prevalence of rabies in non-hematophagous bats. Except for the report of Silva et al 9 , similar studies are lacking in the city and even in the State of Rio de Janeiro. Thus, this paper seeks to contribute to a better understanding of this disease in the city, and to encourage the implementation of health education programs and investment in monitoring systems of these reservoirs in order to increase the number of animals sent for diagnosis.…”

Introduction: Rabies is one of the most known lethal zoonosis, responsible for 55,000 human deaths per year. It is transmitted to humans mainly by the bite of domestic or wild animals infected with the virus. This paper shows the circulation of this virus in non-hematophagous bats in the City of Rio de Janeiro, Brazil. Methods: A survey was performed on the number of bats that had been sent for diagnosis by the Seção de Virologia of the Instituto Municipal de Medicina Veterinária Jorge Vaitsman and were positive for rabies. The positive animals were identified, and the isolated viruses were sent for antigenic typification with indirect immunofluorescence. The results were compared with the antigenic panel of the Centers for Disease Control and Prevention. Results: During 2001-2010, the laboratory received 555 non-hematophagous bats for rabies diagnosis, with 198 (35.7%) from Rio de Janeiro City. A total of 11 (5.5%) animals were positive for this disease. Antigenic typification revealed the predominance of variant 3 in 9 (81.8%) of the isolated viruses; 1 virus was classified as variant 4 and 1 variant was identified that segregated with the viruses in insectivorous bats. Conclusions: The data obtained in this study showed the presence of the rabies virus in synanthropic populations of non-hematophagous bats in the City of Rio de Janeiro. The circulation of this agent in these animals represents a serious risk to human and animal health and requires attention and control measures by the authorities.

“…In urban areas, this virus has been isolated mainly from insectivorous and frugivorous bats [8][9][10][11][12] . However, up to now, no human rabies cases have been registered in Brazil resulting from aggression by these bats involving viral variants related to these species.…”

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.

“…It is highly likely that these results are underestimated due to the limited number of published reports concerning positive bats in these regions of the country. Among the few papers 11,14,17,20,21,25,43,52,62,66,67,70,78,79,81,82 reporting the sex of rabies positive bats, 47 were female: 13 belonging to Molossidae, 23 to Vespertilionidae and 11 A. lituratus of the Phyllostomidae family; 43 were male belonging to Molossidae (13), Vespertilionidae (14) and Phyllostomidae (16). CUNHA et al (2006) 21 reported 68 positive bats, 33 females and 35 males, but species were not shown.…”

“…Regarding bat age, reports are also scarce 20,21,25,43,66,67,70,78,82 . The majority were adults (88%) belonging to Molossidae (7), Vespertilionidae (7) and Phyllostomidae (8).…”

SUMMARYThis paper presents an updated list of bat species positive for rabies in Brazil. It was developed based on database research via the internet, of international and national literature and annals of the most important technical and scientific meetings related to rabies and chiroptera in Brazil from 1996 to 2009. The new list of rabies positive bats consists of 41 species, belonging to 25 genera and three families: Phyllostomidae 43.9%, Vespertilionidae 29.3% and Molossidae 26.8%. In addition, questions were raised regarding the lack of data, including sex, age, circumstances and location of bat capture and incomplete and outdated species identification. Results of genetic and antigenic studies performed on Brazilian rabies positive bats were shown.
