Lyssaviruses are not pathogenic for bats (1)

-Prevalence of VRAB antibodies above 60% in a healthy colony of tailed bat (Tadarida brasiliensis) in USA (Steece –1989- Journal of Wildlife Diseases 25: 490-496 )

-Prevalence of EBLV1 antibodies above 20% in several colonies of serotine bats (Eptesicus isabellinus) in Spain. One seropositive individual captured healthy one year later(Pérez Jordá –1994- Journal of Wildlife Diseases 3: 372-377)

- Presence of EBLV1 in healthy Rousettus aegyptiacus months after an outbreak in a captive colony in The Netherlands. Virus is detected by PCR and IF on brain and other organs. (Wellenberg –2002- Archives of Virology 147:349-361)

- Presence of EBLV1 ARN on oro-pharyngeal swabs of healthy serotine bats in Spain, recovery of some positive individuals one year after.(Echevarría –2001- Journal of Clinical Microbiology 39(10): 3678-3683)

Lyssaviruses are not pathogenic for bats (2)

- Detection of EBLV2 specific antibodies on Daubenton´sBats from Scotland.(Brookes -2005- Emerging Infectious Diseases 11(4): 572-578).

Lyssaviruses are not pathogenic for bats (3)

- Detection of EBLV1 specific antibodies and RNA on blood pellets of different bat species other than serotine bats from healthy colonies in Spain. (Serra-Cobo –2002- Emerging Infectious Diseases 8 (4): 413-420)

- Survival of Tadarida brasiliensis after aerosol exposition to RABV. (Davis –2007- Journal of infectious Diseases195:1144-1150)

- Survival of Eptesicus fuscus after inoculation of RABV(Shankar –2004- Journal of Wildlife Diseases 40(3): 403-413)

Individuals captured ALWAYS in the same colony

Genetic isolation of colonies

Different haplotype distribution on each colony

Conclusion

Genetic isolation of Eptesicus isabellinus

natural colonies reflects the lack of interchange of

individuals that causes independent epidemiological

circulation of EBLV1.

BODY CONDITION INDEX AND PATTERN OF INFECTION

Bats with EBLV1 RNA in oral cavity are healthy

Many infections are subclinical with asymptomatic

presence of virus in oro-pharyngeal cavity.

Conclusion

LYSSAVIRUSES ARE NOT THE ONLY BAT RHABDOVIRUSES

244 oro-pharyngeal swabs from healthy Eptesicus isabellinus captured in Spain. Two relevant sequences obtained.
