“…In the present study, eight isolates were genetically characterized as the lineage circulating in D. rotundus (related to AgV3), which is now known to very probably consist of two distinct yet phylogenetically very close genetic lineages (Brandão et al., ; Shoji et al., ; Kobayashi et al., ; Albas et al., ; Fahl et al., ) maintained in independent epidemiological cycles by D. rotundus and the fruit‐eating bat Artibeus lituratus .…”

“…In the last few years, the importance of Artibeus spp in public health has increased because of the growth in the numbers of these bats in urban areas; furthermore, the fact that they share roosts with D. rotundus (Uieda et al., ; Cunha et al., ; Sodré et al., ) means that these species require special attention. When dogs and cats are infected by bats, the transmitter is generally not known at first, and the real source of the infection can only be established by characterization of the lineages responsible for the infection (Fahl et al., ). However, the fragment of the N gene analysed in the present study is not large enough to differentiate between these two bat lineages and characterize precisely the source of infection as we analysed 193‐bp fragment while Fahl et al.…”

In Brazil, rabies control in dogs and cats was pioneered by the state of São Paulo with the adoption of the Pan American Health Organization recommendations for prophylaxis and control, which led to a reduction in rabies cases from 1994 onwards. As a result of these measures, the rabies virus (RABV) genetic lineage associated with dogs has not been found in the state since 1998, and all the cases in domestic animals reported since then have been caused by bat-associated lineages of RABV. In the light of this, this study sought to investigate rabies cases in dogs and cats in the state of São Paulo between 2005 and 2014 and identify the associated transmission cycles by characterizing the RABV lineages responsible for these cases. Nine samples from dogs (n = 5) and from cats (n = 4) were collected between 2005 and 2014. The tenth animal, a rabid cat, was analysed by a different laboratory. The N gene nucleotide sequences obtained were analysed with the neighbor-joining algorithm and Kimura 2-parameter model using the MEGA 6 program. Phylogenetic analysis revealed that the genetic lineages identified in all the samples were those circulating in Brazilian bats. The findings of this study demonstrate that bats play an important role in the transmission of rabies to domestic animals in São Paulo state and that emphasis should be placed on the implementation of public policies to support surveillance of chiropterans for rabies.

“…We observed that 33.3% of the samples from domestic canines with confirmed rabies were found in varieties compatible with AgV3 from VBs. However, it is worth mentioning that the antigenic and genetic characterizations do not indicate the attacking bat species (Castilho et al., ; Fahl et al., ; Kobayashi et al., ). According to Schneider et al.…”

RESUMEN Objetivos. Describir el perfil epidemiológico de las personas discapacitadas por accidentes de tránsito (AT) en Perú. Materiales y métodos. Análisis secundario de la Encuesta Nacional Especializada Sobre Discapacidad (ENEDIS) del año 2012. Además, se realizó un análisis ecológico con los registros de AT del Ministerio de Transportes y Comunicaciones. Resultados. 49 036 personas reportaron algún tipo de discapacidad por accidentes de tránsito (DAT); 81,3% de los discapacitados reside en zonas urbanas. La discapacidad reportada más frecuente fue limitación en la locomoción y destreza (77,4%), seguida de la discapacidad visual (22,9%). Se reporta dependencia en 44,7% de las personas con discapacidad. Las regiones con mayor prevalencia de AT presentan mayor prevalencia de discapacidad por accidente de tránsito (Coeficiente de Spearman: 0,426, p=0,034). Conclusiones. La mayor parte de los discapacitados por AT proceden de la zona urbana, son varones y se encuentran en la edad económicamente productiva. La forma más común de limitación es la de locomoción. Gran parte de los afectados no reciben ningún tipo de rehabilitación, lo que acentúa la inequidad en salud relacionada a los accidentes de tránsito. Palabras clave: Accidentes de tránsito; Personas con discapacidad; Prevalencia (fuente: BIREME). ABSTRACT Objectives. To describe the epidemiological profile of people living with disabilities due to traffic accidents (TA) in Peru. Materials and methods. Secondary analysis of the National Survey Specialized on Disability (ENEDIS) of 2012 and an ecological analysis of TA records of the Ministry of Transportation and Communications was done. Results. Disability by traffic accidents (DAT) was reported by 49,036 persons; 81.3% of whom live in urban areas. The most frequent disability was limited locomotion and skill (77.4%), followed by visual impairment (22.9%). Dependence for activities was reported in 44.7% of persons with disabilities. The regions with the highest prevalence of TA have a higher prevalence of disability by traffic accidents (Spearman coefficient: 0.426, p=0.034). Conclusions. Most of disability due to TA is found in urban areas, correspond to males and consist of persons in economically productive age. The most common form of disability is in locomotion. Most of individuals do not receive any form of rehabilitation, which accentuates health inequity related to traffic accidents.

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.
