“…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.…”

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raised regarding the lack of data, including sex, age, circumstances and location of bat capture and incomplete and outdated species identification.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.

“…Although some kinds of insectivorous bats have been diagnosed as RV-positive in Brazil, there have been no reports of the human case on infection with insectivorous bat RV variants until now. RVpositive insectivorous bats were, however, found in urban areas, and this fact has been considered as important problems in public health [1,6,17,21].As there is little information about the genetic characteristics of bat-related RVs in Brazil, authors determined nucleotide sequences on the N gene of RVs isolated from 9 Brazilian bat species. Phylogenetic analysis was also performed for the epidemiological study with the isolates identified previously.…”

ABSTRACT. A molecular epidemiological analysis was performed in 19 rabies viruses (RVs) isolated from haematophagous, frugivorous and insectivorous bats, in Sao Paulo, Brazil. The authors carried out RT-PCR for amplification of the RV nucleoprotein (N) gene, and determined 1,335 nucleotide sequences of N gene by direct sequencing method. Phylogenetic analysis, which was based on the N gene of Brazilian RV isolates identified presently and previously, revealed that RVs isolated from bats were genetically divided into four lineages had a tendency to depend on the host bat species. Rabies viruses (RVs) isolated in Brazil belong to genotype 1 of genus lyssavirus, family Rhabdoviridae. Ito et al. [7,8] reported that main reservoirs of RVs were dogs and vampire bats and that the RVs were classified into dogrelated RVs and vampire bat-related RVs in Brazil. In some areas of Brazil, the rabies outbreaks by both dog-and batrelated RVs occurred at the same time [7]. RVs have been isolated from not only haematophagous bats but also frugivorous and insectivorous bats in Brazil. In Argentina, RVs isolated from frugivorous bats (Artibeus lituratus) were identified to be the variant of RV associated with haematophagous bats by use of the monoclonal antibody panels [4]. Recently we have demonstrated that RVs isolated from Brazilian frugivorous bats (Artibeus spp.) were phylogenetically characterized as the vampire bat-related RV [18].There are many reports of human cases on infection with insectivorous bat RVs, and the number of the cases tend to increase in North America [10][11][12]. In 2002, Favi et al. [5] reported that insectivorous bat (Tadarida brasiliensis) RV variant was isolated from a human patient in Chile. In Colombia and Venezuela insectivorous bat RV variants were also isolated from dogs and cats, which were main RVtransmitters to human [2,14]. Although some kinds of insectivorous bats have been diagnosed as RV-positive in Brazil, there have been no reports of the human case on infection with insectivorous bat RV variants until now. RVpositive insectivorous bats were, however, found in urban areas, and this fact has been considered as important problems in public health [1,6,17,21].As there is little information about the genetic characteristics of bat-related RVs in Brazil, authors determined nucleotide sequences on the N gene of RVs isolated from 9 Brazilian bat species. Phylogenetic analysis was also performed for the epidemiological study with the isolates identified previously. MATERIALS AND METHODS Viruses:In this study, 19 RVs were isolated from 3 haematophagous bats (Desmodus rotundus), 1 frugivorous bat (Artibeus lituratus), 13 insectivorous bats (3 Nyctinomops laticaudatus, 2 Eumops auripendulus, 4 Eptesicus furinalis, 2 Molossus molossus, 1 Molossus abrasus and 1 Molossus rufus) and 2 unclassified bats, and their nucleoprotein gene sequences were determined. Brain materials from these bats were diagnosed as RV-positive by immunofluorescent antibody test (FAT) using a rabbit polyclonal anti-rabies nucle...

“…Entre estos, estaba el primer registro de rabia en la especie Nyctinomops macrotis (Gray, 1840) en Brasil (Uieda et al, 1995). Al final de 1998, se registró un caso en murciélago frugívoro (Passos et al, 1999) (Martorelli et al, 1995;Martorelli et al, 1996;Bernardi et al, 1998;Passos et al, 1998;Uieda, 1998;Silva et al, 1999). Posiblemente el mayor número de casos de rabia en murciélagos no hematófagos diagnosticados en el Estado de São Paulo, se debe a la vigilancia epidemiológica de RABV en quirópteros en esta región.…”

RESUMENFrente al desafío que la rabia representa para la industria pecuaria y la salud pública en América Latina, el presente artículo tiene como objetivo hacer una revisión de literatura amplia y crítica sobre la epidemiología de la rabia transmitida por murciélagos en Brasil. El tema es abordado inicialmente desde una perspectiva histórica hasta la caracterización molecular de aislamientos del virus, para finalmente contrastar con la situación de otros países de las Américas. La información referente a Brasil es presentada de manera separada debido a la gran abundancia de especies de murciélagos de diversos hábitos alimenticios, implicadas en la transmisión del virus de la rabia y las complejas relaciones entre los ciclos epidemiológicos revelados por estudios de tipificación antigénica y análisis filogenético, lo cual ha permitido reconocer con más nitidez, la importancia de los quirópteros como reservorios y transmisores de esta enfermedad. Este nuevo escenario epidemiológico exige reexaminar las medidas de control aplicadas hasta el momento, desde un abordaje multidisciplinar, así como cooperación intersectorial y participación por parte de la comunidad.Palabras clave: epidemiología, murciélagos, rabia. ABSTRACTConsidering that rabies represents a challenge for the livestock industry and public health in Latin America, this article is intended to do a comprehensive and critical literature review on the epidemiology of rabies transmitted by bats in Brazil. The subject is addressed from a historical perspective to molecular characterization of rabies virus isolates and finally making a contrast with other countries of the Americas. Information concerning Brazil is presented separately because of the abundance of bats species with different feeding habits, involved in the transmission of rabies virus and the complex relationships between epidemiological cycles in this country, which have been disclosed by antigenic typing and phylogenetic analysis. This has allowed to recognize more clearly the importance of bats as reservoirs and transmitters of this disease. This new epidemiological scenario requires reappraising current control measures, using a multidisciplinary approach, intersectoral cooperation and community participation.
