Bat-borne rabies in Latin America.

Bottom Line: Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America.Research at coarse spatial scales must strive to understand rabies ecology; basic information on distribution and population dynamics of many Latin American and Caribbean bat species is needed; and detailed information on effects of landscape change in driving bat-borne rabies outbreaks remains unassessed.Finally, integrated approaches including public health, ecology, and conservation biology are needed to understand and prevent emergent diseases in bats.

ABSTRACT
The situation of rabies in America is complex: rabies in dogs has decreased dramatically, but bats are increasingly recognized as natural reservoirs of other rabies variants. Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America. Rabies virus is widespread in Latin American bat species, 22.5%75 of bat species have been confirmed as rabies-positive. Most bat species found rabies positive are classified by the International Union for Conservation of Nature as "Least Concern". According to diet type, insectivorous bats had the most species known as rabies reservoirs, while in proportion hematophagous bats were the most important. Research at coarse spatial scales must strive to understand rabies ecology; basic information on distribution and population dynamics of many Latin American and Caribbean bat species is needed; and detailed information on effects of landscape change in driving bat-borne rabies outbreaks remains unassessed. Finally, integrated approaches including public health, ecology, and conservation biology are needed to understand and prevent emergent diseases in bats.

f03: Numbers of rabies-positive species and antigenic variants of rabiesreported by country (Table 1). Ven. =Venezuela.

Mentions: In all, 75 (22.5%) Latin American bat species have been confirmed asrabies-positive, at least as incidental records (see Table 1). The countries with more bat species rabies-positive reports wereBrazil (43), Mexico (31), and Argentina (13; Fig.3). Only Guyana, Suriname, and Haiti are countries lacking bat-rabies records.It was found that the number of rabies-positive species is not related to number of batspecies (richness) reported per country (r2 = 0.1238, df = 24, p = 0.078). From the first search ofarticles (i.e., Web of Science), no association was found (r = 0.2768,df = 7, P = 0.4708) between the number of bat species and publicationsby country; for example, Chile, with the fewest bat species, has nine publications aboutbat-borne rabies while Colombia with the highest number of bat species has only fourpublications. An association was found between number of publications and rabies AgV bycountry (r = 0.775, df = 7, p = 0.0142), as well as anassociation between the number of publications and the number of bat speciesrabies-positive by country (r = 0.883, df = 7, p =0.001).
