Genetic diversity and hematological and biochemical alterations in Alouatta primates naturally infected with hemoplasmas in Brazil.

•26.47% of Allouata maintained in captivity in zoos in the state of São Paulo, Brazil, were positive for hemoplasmas.•Monocyte and lymphocite counts were higher in hemoplasma-positive howlers.•Platelets counts were decreased in hemoplasma-positive howlers.•Five different 16S rRNA hemoplasma genotypes are circulating in non-human primates in the world.•There is a separation between the 16S rRNA sequences of hemoplasmas that infect Sapajus and Allouata primates in Brazil.
