Rabies is an zoonotic infectious disease, caused by rabies virus (RABV). The bats with canids
are the main RABV reservoirs, accounting respectively for maintaining the air cycles and
terrestrial of the disease. This study aimed to identify interactions between the virus and the
reservoir in air rabies cycle. For this, the presence of RABV was investigated in bat saliva
samples from different species. Thirty-six capture bats were held in Maringá Region Parana,
southern Brazil, from April to December 2013. The bats were captured with the help of nylon
nets and placed in cotton bags. Were registered biometric data and collected a sample of oral
swab of each especimen. For the identification of RABV, the semi-nested RT-PCR technique
("Reverse transcription polymerase chain reaction") targeting the N gene encodes the
nucleoprotein of the virus was performed. Data analysis was performed using descriptive
statistics. Throughout the study, were captured 444 bats belonging to four families and fifteen
species. The RABV was not identified in the evaluated samples. These results demonstrate
the absence of excretion of RABV in the saliva of healthy bats in the studied area and
reinforce the need for more studies about the maintenance of rabies in different species of
bats.
