First record of the invasive alien species Axis axis (Erxleben, 1777) (Artiodactyla: Cervidae) in Brazil Biota Neotropica
Sponchiado,Jonas; Melo,Geruza Leal; Cáceres,Nilton Carlos.
The exotic alien species Axis axis was introduced in the Americas at the beginning of last century and since then has established itself, expanding its distribution. This is the first record of this species in Brazil. In the extreme south of the country, an individual of A. axis was recorded with a camera trap in the Espinilho State Park. The area is close to the border of Uruguay and Argentina, countries where the species is established and from where this individual presumably originated. The Pampas biome is strongly disturbed by human activity in Brazil and since many native mammal species such as the Pampas deer Ozotoceros bezoarticus are threatened regionally. It is alarming that exotic populations can potentially rapidly expand their ranges in the...

ABSTRACT: This study aimed to evaluate exposure of wild small mammals to spotted fever group (SFG) rickettsiae in Mato Grosso do Sul State, central-western Brazil. Serum samples of 68 small mammals were analyzed by indirect immunofluorescence assay (IFA) against six Rickettsia species from Brazil. Overall, 37.5% (9/24) marsupials and 6.8% (3/44) small rodents were seroreactive to at least one of the Rickettsia species, with end point titres ranging from 64 to 512. These results suggested that wild small mammals were infected by SFG rickettsiae, and could participate in the ecology of rickettsiae in Mato Grosso do Sul, Brazil.
