RESUMO
BACKGROUND: International organizations advocate for the elimination of dog-mediated rabies, but there is only limited guidance on interpreting surveillance data for managing elimination programmes. With the regional programme in Latin America approaching elimination of dog-mediated rabies, we aimed to develop a tool to evaluate the programme's performance and generate locally-tailored rabies control programme management guidance to overcome remaining obstacles. METHODS: We developed and validated a robust algorithm to classify progress towards rabies elimination within sub-national administrative units, which we applied to surveillance data from Brazil and Mexico. The method combines criteria that are easy to understand, including logistic regression analysis of case detection time series, assessment of rabies virus variants, and of incursion risk. Subjecting the algorithm to robustness testing, we further employed simulated data sub-sampled at differing levels of case detection to assess the algorithm's performance and sensitivity to surveillance quality. RESULTS: Our tool demonstrated clear epidemiological transitions in Mexico and Brazil: most states progressed rapidly towards elimination, but a few regressed due to incursions and control lapses. In 2015, dog-mediated rabies continued to circulate in the poorest states, with foci remaining in only 1 of 32 states in Mexico, and 2 of 27 in Brazil, posing incursion risks to the wider region. The classification tool was robust in determining epidemiological status irrespective of most levels of surveillance quality. In endemic settings, surveillance would need to detect less than 2.5% of all circulating cases to result in misclassification, whereas in settings where incursions become the main source of cases the threshold detection level for correct classification should not be less than 5%. CONCLUSION: Our tool provides guidance on how to progress effectively towards elimination targets and tailor strategies to local epidemiological situations, while revealing insights into rabies dynamics. Post-campaign assessments of dog vaccination coverage in endemic states, and enhanced surveillance to verify and maintain freedom in states threatened by incursions were identified as priorities to catalyze progress towards elimination. Our finding suggests genomic surveillance should become increasingly valuable during the endgame for discriminating circulating variants and pinpointing sources of incursions.

OBJECTIVES: To demonstrate the importance of country surveillance systems for leptospirosis and their use for preliminary epidemiological analysis, as well as to generate research questions for future, morecomprehensive studies on the disease. METHODS: In 2015, for the first time, the Pan American Health Organization (PAHO) included human cases of leptospirosis in its Regional Core Health Data Initiative, an open-access database that collects annual health indicators from the countries and territories of the Americas. This new information was used to analyze leptospirosis cases by country and sex and to calculate cumulative incidence rates. Maps were used to help present the results. To supplement that general review of leptospirosis in the Americas, more detailed descriptions of the epidemiological situation and the surveillance programs of four selected countries (Brazil, Colombia, Cuba, and Honduras) were provided. RESULTS: In this first year of PAHO requesting leptospirosis data, of the 49 countries and territories in the Americas, 38 of them (77.6%) reported information. Among those 38, 28 of them (73.7%) reported the presence of human cases; the majority of instances of zero cases were in Caribbean territories. From those 28, a total of 10 702 human cases were recorded. The largest numbers of cases in Latin America were in Brazil (40.2%), Peru (23.6%), Colombia (8.8%), and Ecuador (7.2%). The cumulative incidence rate for Latin America was estimated to be 2.0 per 100 000 population. On average, 65.1% of cases were males. CONCLUSIONS: This study demonstrates that many countries in Latin America are making efforts to establish strong surveillance systems and programs for leptospirosis. The study also shows the importance of having leptospirosis surveillance systems as well as how the information generated can be used for evidence-based decision-making on leptospirosis.
RESUMO
Cystic echinococcosis (CE) or hydatidosis, a parasitic zoonosis caused by a cestode of the family Taeniidae, species Echinococcus granulosus, is endemic in Argentina, Chile, Peru, Uruguay, and southern Brazil. This report presents CE figures for these five countries in 2009 - 2014 and proposes indicators to measure national control programs. Nearly 5 000 new CE cases were diagnosed annually in the five countries during the study period. The average case fatality rate was 2.9%, which suggests that CE led to approximately 880 deaths in these countries during the 6-year period. CE cases that required secondary or tertiary health care had average hospital stays of 10.6 days, causing a significant burden to health systems. The proportion of new cases (15%) in children less than 15 years of age suggests ongoing transmission. Despite figures showing that CE is not under control in South America, the long-standing implementation of national and local control programs in three of the five countries has achieved reductions in some of the indicators. The Regional Initiative for the Control of CE, which includes the five countries and provides a framework for networking and collaboration, must intensify its efforts.

BACKGROUND: Hantavirus infection is an emerging zoonosis transmitted by wild rodents. In Brazil, high case-fatality rates among humans infected with hantavirus are of serious concern to public health authorities. Appropriate preventive measures partly depend on reliable knowledge about the geographical distribution of this disease. METHODS: Incidence of hantavirus infections in Brazil (1993-2013) was analyzed. Epidemiological, socioeconomic, and demographic indicators were also used to classify cities' vulnerability to disease by means of multi-criteria decision analysis (MCDA). RESULTS: From 1993 to 2013, 1752 cases of hantavirus were registered in 16 Brazilian states. The highest incidence of hantavirus was observed in the states of Mato Grosso (0.57/100,000) and Santa Catarina (0.13/100,000). Based on MCDA analysis, municipalities in the southern, southeastern, and midwestern regions of Brazil can be classified as highly vulnerable. Most municipalities in northern and northeastern Brazil were classified as having low vulnerability to hantavirus cardiopulmonary syndrome. CONCLUSIONS: Although most human infections by hantavirus registered in Brazil occurred in the southern region of the country, a greater vulnerability to hantavirus was found in the Brazilian Midwest. This result reflects the need to strengthen surveillance where the disease has thus far gone unreported.
RESUMO
Echinococcosis is a zoonotic disease relevant to public health in many countries, on all continents except Antarctica. The objective of the study is to describe the registered cases and mortality from echinococcosis in Brazil, from 1995 to 2016. The records of two national databases, the Hospital Information System (HIS) and the Mortality Information System (MIS), were accessed during the period of 1995-2016. Demographic, epidemiological, and health care data related to the occurrence of disease and deaths attributed to echinococcosis in Brazil are described. The results showed that 7955 records of hospitalizations were documented in the HIS, during the study period, with 185 deaths from echinococcosis, and 113 records of deaths were documented in the MIS Deaths in every state of Brazil in the period. When comparing between states, the HIS showed great variability in mortality rates, possibly indicating heterogeneity in diagnosis and in the quality of health care received by patients. Less severe cases that do not require specialized care are not recorded by the information systems, thus the true burden of the disease could be underrepresented in the country. A change in the coding of disease records in the HIS in the late 1990s, (the integration of echinococcosis cases with other pathologies), led to the loss of specificity of the records. The records showed a wide geographic distribution of deaths from echinococcosis, reinforcing the need to expand the notification of the disease in Brazil. Currently, notification of cases is compulsory in the state of Rio Grande do Sul.
RESUMO
Brazilian spotted fever (BSF) is caused by the bacterium Rickettsia rickettsii. Because of its high case-fatality rate and apparent increase in areas of transmission, it is considered to be the rickettsial illness of primary public health interest. Cases of this disease have historically occurred in Southeastern Brazil. This article reports the first fatal case of BSF in Southern Brazil. This case high lights the importance of BSF to be considered as a differential diagnosis for acute hemorrhagic fever in areas where cases of BSF may not be expected.

BACKGROUND: Spotted fever is a tick-borne rickettsial disease. In Brazil, its notification to the Ministry of Health is compulsory. Since 2007, cases of spotted fever have been integrated to the Notifiable Diseases Information System, and epidemiological analyzes are part of the routines on surveillance programs. METHODS: This descriptive study updates epidemiological information on cases of spotted fever registered in Brazil between 2007 and 2015. RESULTS: In Brazil, 17,117 suspected cases of the disease were reported and 1,245 were confirmed in 12 states, mainly in São Paulo (550, 44.2 %) and Santa Catarina (276, 22.2 %). No geographic information was registered for 132 cases (10.6 %). Most of the infected people were men (70.9 %), mainly in rural areas (539, 43.3 %), who had contact with ticks (72.7 %). A higher number of suspected cases were registered between 2011 and 2015, but the number of confirmed cases and the incidence were relatively low. Moreover, 411 deaths were registered between 2007 and 2015, mainly in the southeastern region of the country, where the case-fatality rate was 55 %. Lack of proper filling of important fields of notification forms was also observed. CONCLUSIONS: The results showed expansion of suspected cases of spotted fever and high case-fatality rates, which could be related to diagnostic difficulties and lack of prompt treatment. These factors may comprise limitations to the epidemiological surveillance system in Brazil, hence improvement of notification and investigation are crucial to reduce morbidity and mortality due to spotted fever in Brazil.
RESUMO
The American region has pledged to eliminate dog-mediated human rabies by 2015. As part of these efforts, we describe the findings of a desk and field mission review of Haiti's rabies situation by the end of 2013. While government officials recognize the importance of dog-mediated rabies control, and the national rabies plan adequately contemplates the basic capacities to that effect, regular and sufficient implementation, for example, of dog vaccination, is hampered by limited funding. Compounding insufficient funding and human resources, official surveillance figures do not accurately reflect the risk to the population, as evidenced by the large number of rabid dogs detected by focalized and enhanced surveillance activities conducted by the Ministry of Agriculture, Natural Resources and Rural Development (MARNDR) and the Health and Population Ministry (MSPP) with the technical assistance of the United States Centers for Disease Control and Prevention. Although international support is common, either in the form of on-the-ground technical support or donations of immunobiologicals, it is not comprehensive. In addition, there is limited coordination with MARNDR/MSPP and with other actors at the strategic or operational level due to human resources limitations. Given these findings, the 2015 elimination goal in the region is compromised by the situation in Haiti where control of the disease is not yet in sight despite the best efforts of the resolute national officials. More importantly, dog-mediated rabies is still a threat to the Haitian population.

Cystic echinococcosis (CE) or hydatidosis, a parasitic zoonosis caused by a cestode of the family Taeniidae, species Echinococcus granulosus, is endemic in Argentina, Chile, Peru, Uruguay, and southern Brazil. This report presents CE figures for these five countries in 2009 – 2014 and proposes indicators to measure national control programs. Nearly 5 000 new CE cases were diagnosed annually in the five countries during the study period. The average case fatality rate was 2.9%, which suggests that CE led to approximately 880 deaths in these countries during the 6-year period. CE cases that required secondary or tertiary health care had average hospital stays of 10.6 days, causing a significant burden to health systems. The proportion of new cases (15%) in children less than 15 years of age suggests ongoing transmission. Despite figures showing that CE is not under control in South America, the long-standing implementation of national and local control programs in three of the five countries has achieved reductions in some of the indicators. The Regional Initiative for the Control of CE, which includes the five countries and provides a framework for networking and collaboration, must intensify its efforts.
La equinococosis quística o hidatidosis, zoonosis parasitaria causada por un cestodo de la especie Echinococcus granulosus, familia Taeniidae, es endémica en Argentina, Chile, Perú, Uruguay y el sur del Brasil. En este informe se presentan datos sobre la equinococosis quística registrados en estos cinco países entre los años 2009 y 2014, y se proponen indicadores para medir el desempeño de los programas nacionales de control. Durante el período de estudio, en los cinco países se diagnosticaron casi 5 000 casos nuevos por año. La tasa de letalidad promedio fue del 2,9 %, lo que indica que la equinococosis quística causó aproximadamente 880 defunciones en estos países en el período de 6 años estudiado. Los casos que debieron recibir atención de salud secundaria o terciaria tuvieron una estadía hospitalaria promedio de 10,6 días, lo que ha generado una carga significativa para los sistemas de salud. La proporción de casos nuevos de niños menores de 15 años (15 %) indica que la transmisión no se ha interrumpido. A pesar de que los datos muestran que la enfermedad no está controlada en América del Sur, tres de los cinco países disponen de programas nacionales y locales de control desde hace muchos años, los que han logrado reducir algunos de los indicadores. Es preciso que la Iniciativa Sudamericana para el Control de la Equinococosis Quística, que incluye a los cinco países y contribuye con un marco para la formación de redes y la colaboración, redoble sus esfuerzos para lograr el control de la enfermedad.
A equinococose cística ou hidatidose, zoonose parasitária causada por um céstodo da família Taeniidae e espécie Echinococcus granulosus, é endêmica na Argentina, Chile, Peru, Uruguai e no sul do Brasil. Neste artigo são apresentadas as estimativas da hidatidose nos cinco países de 2009 a 2014 e propostos indicadores para avaliar os programas nacionais de controle. Cerca de 5 mil casos novos de hidatidose foram diagnosticados por ano nos cinco países no período de estudo. A taxa de letalidade média foi de 2,9%, o que indica que esta doença causou aproximadamente 880 mortes nestes países no período de 6 anos. Nos casos de hidatidose que precisaram de atenção de saúde secundária ou terciária, a duração média da internação hospitalar foi de 10,6 dias, representando uma sobrecarga considerável aos sistemas de saúde. O percentual de novos casos (15%) em indivíduos menores de 15 anos de idade indica transmissão contínua. Apesar de as estimativas mostrarem que a hidatidose não está controlada na América do Sul, a execução permanente de programas municipais e nacionais de controle em três dos cinco países tem redundado na redução de alguns dos indicadores. A Iniciativa Regional para Controle da Hidatidose, que integra os cinco países em uma estrutura para trabalho em conjunto e colaboração, deve redobrar os seus esforços.

Introdução: A febre maculosa (FM) é uma doença transmitida por carrapatos, o que, no Brasil, preocupa as autoridades do Sistema Único de Saúde (SUS) por apresentar elevados coeficientes de letalidade. Objetivo: Descrever os conhecimentos e as atitudes de prevenção sobre a FM entre profissionais do SUS. Métodos: Foi realizado entre os meses de outubro a dezembro de 2015, um inquérito sobre os conhecimentos e as atitudes de prevenção sobre a FM entre os profissionais da saúde. Um questionário na plataforma FormSUS foi submetido a 426 profissionais de todo o Brasil que previamente já haviam participado de capacitações e atividades que envolviam o tema em questão. Resultados: vinte unidades federadas foram respondedoras da pesquisa (112/426). Foi possível verificar que a maioria dos profissionais de saúde conhece as condutas de notificação e de investigação epidemiológica. As incorporações recentes no programa de vigilância epidemiológica são de conhecimento da maioria dos respondentes. A rotatividade dos profissionais foi mencionada como principal dificultador das ações de vigilância da doença. Ações de fortalecimento dos programas de vigilância são realizadas de forma esporádica, somente no momento da ocorrência de casos de FM e não ocorrem de forma integral no âmbito do SUS. Conclusão: Cabe a cada segmento do SUS buscar seguir as diretrizes do sistema de vigilância epidemiológica da FM para que, de forma integral, se consiga reverter o panorama de morbimortalidade desta importante doença no Brasil.

Introduction: Spotted fever (SF) it's a tick-borne disease, that in Brazil worries the Unified Health System (named as SUS), because of its high fatality rates. Objective: Describe the knowledge and attitudes of prevention on SF between SUS professionals. Methods: It was realized in 2015, between October and December, an inquiry of the knowledge and attitudes of prevention on SF between health professionals. A questionnaire on FormSUS platform was subjected to 426 professionals from all over Brazil, who previously has participated in training and activities involving the present issue. Results: Twenty federal units answered the inquiry (112/426). It was possible to verify that most health professionals know the conduct of notification and epidemiological research. Recent incorporations in the surveillance program are known to most respondents. The turnover of professionals was mentioned as main complication on the surveillance actions of the disease. Strengthening actions regarding surveillance programs are performed occasionally, only at the time of the incident occurrence, and do not occur integrally in SUS. Conclusion: It's up to each SUS segment seek to follow the guidelines of epidemiological surveillance system for SF, to be able of reverse in full the scenario of morbidity and mortality of this important disease in Brazil.

Conclusions The results showed expansion of suspected cases of spotted fever and high case-fatality rates, which could be related to diagnostic difficulties and lack of prompt treatment. These factors may comprise limitations to the epidemiological surveillance system in Brazil, hence improvement of notification and investigation are crucial to reduce morbidity and mortality due to spotted fever in Brazil.

Background Spotted fever is a tick-borne rickettsial disease. In Brazil, its notification to the Ministry of Health is compulsory. Since 2007, cases of spotted fever have been integrated to the Notifiable Diseases Information System, and epidemiological analyzes are part of the routines on surveillance programs. Methods This descriptive study updates epidemiological information on cases of spotted fever registered in Brazil between 2007 and 2015. Results In Brazil, 17,117 suspected cases of the disease were reported and 1,245 were confirmed in 12 states, mainly in São Paulo (550, 44.2 %) and Santa Catarina (276, 22.2 %). No geographic information was registered for 132 cases (10.6 %). Most of the infected people were men (70.9 %), mainly in rural areas (539, 43.3 %), who had contact with ticks (72.7 %). A higher number of suspected cases were registered between 2011 and 2015, but the number of confirmed cases and the incidence were relatively low. Moreover, 411 deaths were registered between 2007 and 2015, mainly in the southeastern region of the country, where the case-fatality rate was 55 %. Lack of proper filling of important fields of notification forms was also observed. Conclusions The results showed expansion of suspected cases of spotted fever and high case-fatality rates, which could be related to diagnostic difficulties and lack of prompt treatment. These factors may comprise limitations to the epidemiological surveillance system in Brazil, hence improvement of notification and investigation are crucial to reduce morbidity and mortality due to spotted fever in Brazil.(AU)

The objective of this study was to identify the migration period of the genital tubercle and the period of visualization of external genital structures in fetuses of the Dorper breed of sheep derived from natural mating and from fresh, frozen and vitrified embryo transfer. Transrectal ultrasound was performed using a double-frequency linear transducer (6.0 and 8.0 MHz) to monitor 130 ewe fetuses distributed in the four treatments regarding embryo origin. The accuracy of the ultrasound was 100% in this experiment. The fetuses originated from controlled natural mating (NM) and from fresh (FrE), frozen (FE) and vitrified (VE) embryo transfer, with embryos collected 7 days after breeding. Migration of the genital tubercle occurred earlier (P<0.05) in NM (42.21+/-2.86 days) than in FrE (43.98+/-3.00 days), FE (44.97+/-1.83 days) and VE (44.58+/-1.97 days). Visualization of the scrotal bag, prepuce and vulva occurred, respectively, earlier (P<0.05) in NM (45.22+/-1.25, 45.95+/-1.53 and 45.01+/-1.03 days) than in FrE (48.91+/-1.92, 48.52+/-1.41 and 47.41+/-1.41 days), FE (49.97+/-1.08, 49.18+/-2.00 and 47.64+/-1.82 days) and VE (50.12+/-1.66, 49.27+/-1.61 and 47.93+/-1.92 days). The results show that fetal sexing can be accomplished from the 50th day onward in fetuses produced by natural mating and from the 55th day onward in fetuses derived from fresh, frozen and vitrified embryos. It can also be concluded that real-time ultrasonography is a reliable tool for fetal sex determination in sheep taking into account both the location of the genital tubercle and the identification of external genital structures.

As hantaviroses são zoonoses que causam doenças humanas graves como a síndrome cardiopulmonar por hantavírus (SCPH) registrada no continente americano. No Brasil a SCPH é doença de notificação obrigatória aos serviços de saúde por apresentar elevada letalidade e incipiente conhecimento da sua epidemiologia. O presente estudo descreve o perfil epidemiológico da SCPH no Brasil para o período de 2007 a 2012. Foi realizado um estudo descritivo dos registros do Sistema Nacional de Agravos de Notificação, foram analisadas as fichas de notificação e investigação e os dados foram avaliados quanto a completitude da informação, oportunidade e perfil dos casos registrados. Os resultados são apresentados em números brutos, medidas de proporção e tendência central e as analises foram desenvolvidas pelos softwares Excel 2010, Tabwin 32 e TerraView. No período estudado foram notificados 8.456 casos de SCPH, com confirmação de 9 porcento (756/8.456), preferencialmente pelo critério laboratorial 91,1 porcento (689/756). O coeficiente de letalidade médio para o período foi de 38,2 porcento, as maiores incidências da doença foram nos estados do Mato Grosso, Santa Catarina e Distrito Federal e as maiores letalidades no Amazonas, Mato Grosso e São Paulo. Quanto à sazonalidade foram observados casos em todos os meses do ano; os óbitos foram mais frequentes em homens 72,3 porcento (209/289) e maior letalidade 42,3 porcento (80/189) foi observada em mulheres. Os casos acometeram principalmente pessoas que exerciam atividades relacionadas à agricultura 18,8 porcento (90/478) que se expuseram ao ambiente com roedores 36,9 porcento (279/756)...
Hantaviruses are zoonoses that cause serious human diseases in the Americas such as hantavirus pulmonary syndrome (HPS). In Brazil HPS is a notifiable disease to health services due to its high lethality and incipient knowledge of its epidemiology. The present study describes the epidemiology of HPS in Brazil for the period 2007-2012. We conducted a descriptive study of the records of the National Notifiable Diseases System, analyzed the reporting forms and research, and the data were evaluated for completeness of information, opportunity and profile of registered cases. The results are presented as raw numbers, measures of central tendency and proportion and analyses developed using Excel 2010 software, and 32 Tabwin terraView. In the study period 8,456 cases of HPS were reported, with confirmation of 9 percent (756/8,456), ideally by laboratory testing 91.1 percent (689/756). The average coefficient of lethality for the period was 38.2 percent, whilst the highest incidences of the disease were in the states of Mato Grosso, Santa Catarina and the Federal District and the greatest lethalities were in Amazonas, Mato Grosso and São Paulo. Regarding seasonality, cases were observed in all months of the year. Deaths were more frequent in males 72.3 percent (209/289) and high mortality was observed in women 42.3 percent (80/189). The cases were mainly people who conducted activities related to agriculture 18.8 percent (90/478) who were exposed to the rodent environment, 36.9 percent (279/756)...

A reprodução e a morte massiva de plantas de longa vida, como taquaras e bambus, estão associadas historicamente a episódios de ratadas. A superpopulação de roedores, que é favorecida pelo evento reprodutivo desses vegetais, traz consigo grandes prejuízos e riscos de emergências de doenças. Nesta nota, relatamos o episódio de ratada ocorrido no município de São Francisco do Sul, Santa Catarina. Para subsidiar esta comunicação foram feitas observações de campo, entrevistas não estruturadas e coleta de material biológico em novembro de 2012. Foi constatada a reprodução da taquara do gênero Merostachys e a invasão subsequente de domicílios por roedores dos gêneros Oligoryzomys e Akodon, reservatórios de hantavírus, no sul do Brasil.
Reproduction and massive death of long lived plants like bamboo are historically associated with episodes of mouse outbreaks. The over population of rodents that is favored by the reproduction of these vegetables brings big losses and risks of emerging diseases. In this note we report the mouse outbreaks happened in the district of São Francisco do Sul, Santa Catarina, Brazil. In order to supoort this communication we conducted observations, unstructured interview and sand collection of biological material in November 2012. It was found bamboo reproduction of the genus Merostachys and subsequent invasion of houses by rodents of the genus Oligoryzomys and Akodon, which are hantavirus reservoirs, in southern Brazil.

As ideias de desenvolvimento local são controversas, pouco consensuadas e, às vezes, até antagônicas entre si, tanto no Brasil quanto no debate internacional. Diante dessa polêmica, este artigo discute a gestão do desenvolvimento local a partir de instrumentos selecionados por meio de uma análise exploratória não apenas conceitual e teórica, mas sobretudo prática. Do ponto de vista metodológico, foi realizada uma análise comparada de experiências regionalmente distribuídas, levando-se em conta suas inserções em redes sociais e seus resultados econômicos na região em que está inserida (Sul, Sudeste e Nordeste). Percebe-se que refletir sobre o desenvolvimento local desdobra-se em duas frentes: uma de reprodução da lógica capitalista em escala localizada (tradicional) e outra de tentativas contra-hegemônicas (solidária). Assim, algumas questões centrais foram identificadas para orientar uma reflexão sobre a intervenção dos atores da sociedade civil e dos governos na formulação de propostas e iniciativas de desenvolvimento econômico local.
The ideas of local development are controversial, there is little consensus, and sometimes they are even antagonistic, in Brazil and abroad. Given this controversy, this article discusses local development management, based on instruments selected through an exploratory analysis, not only conceptual and theoretical, but above all practical. It presents a comparative analysis of regionally distributed experiences taking into account their insertion in social networks and the economic results in their regions (South, Southeast and Northeast). On reflecting about local development one can perceive that it unfolds in two fronts: locally, a reproduction of the capitalist logic (tradition), and counter-hegemonic attempts (solidarity). Some key issues were identified to guide a reflection on the role of civil society actors and governments in the formulation of proposals and initiatives for local economic development.
RESUMO
São apresentados os resultados de 23 anos de diagnósticos de raiva realizados no Instituto de Pesquisas Veterinárias Desidério Finamor, no Estado do Rio Grande do Sul, Brasil. Entre os anos de 1985 e 2007, um total de 23.460 amostras foram diagnosticadas no laboratório, compreendendo cerca de 95 por cento do número total de amostras submetidas ao diagnóstico laboratorial de raiva no Estado. A metodologia utilizada seguiu técnicas padrões como a imunofluorescência direta (IFD) e inoculação em camundongos (IC). Não ocorreram casos de raiva humana no período. O vírus rábico (VR) foi detectado em 739 (3,1 por cento) amostras, sendo 656 (88,7 por cento) de origem bovina. O vírus foi também identificado em 23 caninos (3,1 por cento), 21 eqüinos (2,9 por cento), 29 quirópteros (4,0 por cento), 4 felinos (0,5 por cento), 3 ovinos (0,4 por cento), 2 suínos (0,27 por cento) e em um animal selvagem de espécie indeterminada (0,13 por cento). O último caso de raiva em cães associado com variantes do vírus endêmicas nessa espécie foi diagnosticado em 1988. Dois episódios de contaminação incidental registrados em um felino em 2001 e em um canino em 2007, associados com variantes do vírus prevalentes em morcegos. Em relação à raiva bovina, os dados aqui apresentados revelam uma marcante diminuição no número de casos de raiva nessa espécie, em comparação com registros prévios. Por outro lado, um aumento no número de casos de raiva em morcegos hematófagos e não hematófagos vem sendo observado; no entanto, não é possível associar este aumento com modificações nas relações vírus/hospedeiro, pois o número de morcegos submetidos para diagnóstico tem igualmente aumentado. Isto provavelmente reflete o aumento do conhecimento sobre o papel de morcegos no ciclo de transmissão, e não necessariamente alterações no vírus e/ou nos hospedeiros.(AU)
The results of 23 years of rabies diagnosis carried out at the Veterinary Research Institute Desidério Finamor, in the state of Rio Grande do Sul, RS, Brazil, are reported. From 1985 to 2007, a total of 23.460 specimens were examined, corresponding to 95 percent of the total number of samples submitted to rabies laboratory diagnosis notified within the state. Diagnostic methods included standard techniques such as the fluorescent antibody test (FAT) and mouse inoculation test (MIT). No cases of human rabies occurred in the period. Rabies virus (RV) was detected in 739 specimens (3.1 percent), from which 656 (88.7 percent) were from cattle. The virus was also identified in specimens from 23 dogs (3.1 percent), 21 horses (2.9 percent), 29 bats (4.0 percent), 4 cats (0.5 percent), 3 sheep (0.4 percent), 2 pigs (0.27 percent) and a wild animal of undetermined species (0.13 percent). The last case of rabies associated with a canine variant was diagnosed in 1988. Two cases of rabies associated with bat variant viruses were reported, in a domestic cat (2001) and in a dog (2007). In cattle, a marked tendency to a decrease in the number of cases was detected in the examined period. In contrast, an increase in the number of cases in haematophagous as well as in non haematophagous bats is noticed. However, as the number of bat specimens submitted for diagnosis has increased, this finding most likely reflects a higher degree of awareness on the possible role for bats in the rabies transmission cycle, rather than any particular changes on the virus or its hosts.(AU)
