dc.description | S1 Fig. Distribution of neutralising antibody titers to DUVV and LBV in bats from southwestern Indian Ocean islands as assessed by the Rapid Fluorescent Focus Inhibition Test. Results represent the proportion of sera from insectivorous and frugivorous bat species titering at 1/25 (the cut off value of positivity), 1/125, and 1/625 among the sera tested positive for each challenge virus. | en_ZA |

Coloured site names and in the chart correspond to the lyssaviruses antibodies detected in bats: sera neutralising DUVV only are in blue; those neutralising LBV only are in red, those cross-neutralising DUVV + EBLV-1 are in yellow. Sites which combine animals which sera neutralised DUVV only, EBLV-1 only, cross-neutralised DUVV and EBLV-1 and animals neutralised LBV only are in brown.

dc.description.abstract | We provide serological evidence of lyssavirus circulation among bats on southwestern Indian Ocean (SWIO) islands. A total of 572 bats belonging to 22 species were collected on Anjouan, Mayotte, La Réunion, Mauritius, Mahé and Madagascar and screened by the Rapid Fluorescent Focus Inhibition Test for the presence of neutralising antibodies against the two main rabies related lyssaviruses circulating on the African continent: Duvenhage lyssavirus (DUVV) and Lagos bat lyssavirus (LBV), representing phylogroups I and II, respectively. A total of 97 and 42 sera were able to neutralise DUVV and LBV, respectively. No serum neutralised both DUVV and LBV but most DUVV-seropositive bats (n = 32/220) also neutralised European bat lyssavirus 1 (EBLV-1) but not Rabies lyssavirus (RABV), the prototypic lyssavirus of phylogroup I. These results highlight that lyssaviruses belonging to phylogroups I and II circulate in regional bat populations and that the putative phylogroup I lyssavirus is antigenically closer to DUVV and EBLV-1 than to RABV. Variation between bat species, roost sites and bioclimatic regions were observed. All brain samples tested by RTPCR specific for lyssavirus RNA were negative. | en_ZA |
