“…Some studies have reported the difficulty of finding hematophagous bats with RABV brain infections or even with least clinical signs of rabies, including Sugay and Nilsson (1966) hematophagous bats, because in Brazil the virus variant isolated in cattle is that same isolated from D. rotundus (Heinemann et al, 2002). The increase in numbers of rabies cases in hematophagous and non-hematophagous bats has been observed, as well as the number of bats that have been diagnosed in every country (Teixeira et al, 2015), possibly as a result of increased knowledge about the role of bats in cycle of rabies transmission and the greater opportunity of perception of the presence of the species in the environment altered by man.…”

“…Urbanization has been providing a variety of resources to bats, especially non-hematophagous, which have been found positive for rabies, such as plants used for afforestation by day and night shelters and other plants as food (Uieda et al 1996). Also, nocturnal public lighting of cities attract insects that are habitually consumed by several species of insectivorous bats (Teixeira et al, 2015).…”

Rabies is a disease caused by a virus belonging to the family Rhabdoviridae, genus Lyssavirus (RABV), and is characterized as a progressive and acute encephalitis that presents high lethality. Between 2002 and 2012, 2149 wild animals were found positive for RABV in Brazil where 79% were associated with the aerial cycle of the disease. As part of the active surveillance of rabies in Brazil, the objective of this study was to investigate the presence of RABV infection in bats captured in the metropolitan region of Rio de Janeiro city. Forty-four bats were tested for RABV at Institute Jorge Vaitsman (IJV), reference laboratory for rabies in Rio de Janeiro State. Of the individuals captured and sent for the diagnosis of rabies, a total of 15 were identified as being hematophagous, all of them belonging to the species Desmodus rotundus. Twenty-four individuals were considered as frugivorous, four as insectivores and one individual (Lonchophylla peracchii) identified as having a pollen/ nectar feeding habit. All specimen sent to RABV diagnosis presented negative results. Considering the active surveillance for RABV in Brazil, studies of fauna survey with serological characterization are important in the strengthening of epidemiological surveillance and protection of human life.

“…Research on the spatial and time distribution of rabies conducted in the states of Minas Gerais, São Paulo, and Bahia shows the influence of factors such as climate, temperature, and rainfall on the occurrence of outbreaks of rabies in certain areas (municipalities), seasons (seasonality), and throughout the years (cyclicity) (Silva et al 2001, Menezes et al 2008, Gomes et al 2011, Teixeira et al 2015.…”

Epidemiological study of rabies in cattle in southern Brazil: spatial and temporal distribution from 2008 to 2017

et al. 2019

Rabies affects several domestic species, causing significant economic losses due to the death of animals in characteristic areas of the southern region of Rio Grande do Sul. In this context, this work aimed to study the epidemiology of rabies outbreaks observed in cattle from January 2008 to December 2017, through its space and time distribution in the southern region of Rio Grande do Sul. We performed an observational and ecological retrospective through the analysis of data recorded in necropsy protocols performed in cattle at the “Laboratório Regional de Diagnóstico” of the “Universidade Federal de Pelotas” (LRD-UFPel). A descriptive data analysis aimed at evaluating the distribution of cases over time. The statistical analysis was performed with Gretl statistical software 1.9.12 (GNU Regression, Econometric, and Time-series Library). To the existence of stationarity was verified with the Dickey-Fuller test, considering a value of p<0.05. From January 2008 to December 2017, 1418 bovine diagnostic materials were received at the LRD-UFPel, and 160 outbreaks of rabies were confirmed in 160 farms located in the 24 municipalities of the LRD-UFPel area of influence. We observed 591 cattle out of a total of 25,886 infected with the virus. We conclude that rabies does not exhibit seasonality in the study region, with a tendency to decrease in frequency in the next years. The disease has an epidemic characteristic in most of the analyzed months (2012-2014), remaining endemic in the remaining period (2011, 2015 and 2016) with sporadic episodes of epidemics in these years. We also observed that as the incidence of the disease increased in the animals and in the properties, there was a geographical spread of the virus for the majority (54.16%) of the municipalities in the area of influence of the LRD-UFPel.

“…The disease is caused by a single-strand RNA virus of the Genus Lyssavirus, Family Rhabdoviridae (RUPPRECHT et al, 2002). In Brazil, rabies is one of the main causes of neurological syndromes in production animals like cattle and horses (RISSI et al, 2010;TEIXEIRA et al, 2015).…”

Evaluation of data input in a rabies testing request form for herbivores

et al. 2020

Bovines and equines are the domestic animals with the highest incidence of rabies in Brazil. This study evaluated the data input in testing request forms for rabies in herbivores accompanying samples sent to a certified laboratory of rabies diagnosis in the state of Rio Grande do Sul, Brazil. Information was obtained systematically from all forms sent to the laboratory in 2013 and 2014 using a collection instrument that listed variables about the kind of form used, municipality of origin, description of the suspected animal, clinical signs, sample collection, and conservation procedure. The 11 most relevant variables (municipality of origin, geographic coordinates, species, gender, breed, age, herd size, clinical signs, persistence of clinical signs, biological material, and sample conservation) were assessed for the quality of the data entered, and percentage data input was calculated per form. In total, 603 forms were sent to the laboratory. The most used form was the FORM SN, (82.0%, 497/603). “Excellent” and “good” data inputs were observed only for one variable describing the location of suspected rabies cases or outbreaks and animals (species, gender, biological material). Quality of data input of variables describing geographic coordinates, age, breed, herd size, clinical signs, persistence of signs, and sample conservation method varied between “average” and “poor”. The data input in testing request forms for herbivores are not dully supplied in suspected cases neurological syndromes, pointing to the need to increase awareness and improve training of field staff.
