Aspectos economicos y epidemiologicos de la agresion del vampiro y de la rabia paralitica en la Argentina y analisis de las propuestas efectuadas para su control

Observations of Sylvatic Rabies in Northern Argentina during Outbreaks of Paralytic Cattle Rabies Transmitted by Vampire Bats (Desmodus rotundus)

“…Reports of rabies in wild species during outbreaks of paralytic rabies are few. The vampire variant of the rabies virus has been isolated from the great fruit-eating bat (Artibeus lituratus) and the savanna fox (Cerdocyon thous; Delpietro et al, 1997). In this article we report the epidemiology and clinical signs observed with those cases, as well as of other cases of rabies in wild animals observed during outbreaks of paralytic rabies in northern Argentina; in these additional cases virus was not typed.…”

“…Paralytic rabies occurs in epidemic form, and more than 50% of vampire bats can die during an outbreak (Delpietro and Russo, 1996). Reports of rabies in wild species during outbreaks of paralytic rabies are few.…”

“…Observations were made between 1969 and 2006 within the area of reported paralytic rabies in Argentina (Delpietro and Russo, 1996). This comprises the territory located north of parallel 29uS and to the east of meridian 66uW, with an area of approximately 550,000 km 2 , including the Provinces of Misiones, Formosa and Chaco, and part of the Provinces of Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero, Santa Fe, and Corrientes (Fig.…”

“…In cases observed after 1992, we also characterized the antigenic variant of the rabies virus isolated with the use of monoclonal antibodies to rabies-virus nucleoprotein (Wiktor and Koprowsky, 1978). For these analyses, brain impressions were tested by the indirect immunofluorescence test with a set of 19 monoclonal antibodies, kindly provided by the US/PHS/CDC (Delpietro et al, 1997).…”

“…1), a savanna fox was observed with difficulty walking, intense aggressiveness, and fury. The fox attempted to attack people, dogs, and any other moving objects; it was euthanized and the vampire variant of rabies virus was isolated from brain (Delpietro et al, 1997). In August 1969, in the suburbs of Posadas, Province of Misiones, Argentina (27u229S, 55u559W; Fig.…”
