Bat Influenza A(HL18NL11) Virus in Fruit Bats, Brazil

Emerg Infect Dis. 2019 Feb;25(2):333-337. doi: 10.3201/eid2502.181246.

Abstract

Screening of 533 bats for influenza A viruses showed subtype HL18NL11 in intestines of 2 great fruit-eating bats (Artibeus lituratus). High concentrations suggested fecal shedding. Genomic characterizations revealed conservation of viral genes across different host species, countries, and sampling years, suggesting a conserved cellular receptor and wide-ranging occurrence of bat influenza A viruses.
