| Abstract | |
Supported by previous studies that selected areas prone for the development of Desmodus rotundus roosts and bovine rabies transmitted by vampire bats in São Paulo state, the Department of Agriculture of the State of São Paulo (CDA) has conducted interventions for bovine rabies control in areas mostly close to the main rivers of surveillance regions. Inquiries of the actual concepts led to the development of a descriptive model to analyze the vampire bat Desmodus rotundus attacks on cattle far beyond main rivers and water streams in the São João da Boa Vista region, São Paulo state. The model was elaborated using satellite images classification, parameters from previous studies about vampire bats behaviour, data from the CDA and the Brazilian Institute of Geography and Statistics (IBGE). All this information was used to build a geographical database and integrate in a Geographical Information System then analyzed through spatial statistical and analytical methods. The results showed that areas close to the main rivers of the towns Aguaí, Casa Branca, Santa Cruz das Palmeiras and Tambaú were found not to be under risk of bat attacks, suggesting that the hypothesis behind the CDA control areas definition does not hold when contracted with the obtained spatial data. The results indicate that the technicians from CDA need to reformulate their strategy for defining the surveillance of vampire bat populations and rabies control. (AU) | |
