molecular characterization of rabies virus isolated from non-haematophagous bats in brazil.	rabies is an important zoonosis that causes thousands of deaths worldwide each year. although the terrestrial cycle, mainly transmitted by dogs, is controlled in brazil, the aerial cycle remains a serious public health issue, besides the economic problem. in the aerial cycle, the haematophagous bat desmodus rotundus is the main source of infection, where several different species of non-haematophagous bats can be infected and can transmit the virus.	2011	22231241
assessing the rabies control and surveillance systems in brazil: an experience of measures toward bats after the halt of massive vaccination of dogs and cats in campinas, sao paulo.	bats are less vulnerable to forest fragmentation than any other mammal, and for that reason, some species can disperse to peri-urban or urban areas. insectivorous bats are abundant in urban areas due to the density of artificial roosts and insects attracted by city lights. inter-species transmission of the rabies virus between bats can occur, and this is the most probable mechanism of virus circulation in bat populations. bats can also transmit the rabies virus to other mammal species, like dogs ...	2013	23597620
