Leishmania incidence
Of the 1,130 total sandfly pools, 42 samples tested positive forLeishmania (3.7% positivity rate). The proportion of infected
pools at a site varied substantially (Appendix S1: Table S3) across all
sites but there was no significant effect of any of the measured
environmental metrics on the likelihood of a pool testing positive forLeishmania (Appendix S1: Fig. S2). Eighteen of the 39 sites had
at least one infected pool with one site (E19) having 100% of pools
(n=3) infected. Aside from this outlier site, sites with infected pools
had RAI values that range from 0.01 – 0.20. Of the 42 positive samples,
11 samples contained sylvatic vertebrates, each of which were known host
species for Leishmania . In those samples, armadillos (n=6) were
the most found taxa and five samples had co-occurrences of sylvatic host
species (two host species found in the same sample) (Fig. 6).
