El objetivo de la investigación fue determinar la presencia de Hepatozoon sp. en el Caimán Blanco (Caiman crocodilus) de vida libre en la zona del Bajo Madre de Dios, ubicado en el departamento de Madre Dios. Se analizaron las muestras tomadas de 30 individuos (4 hembras, 21 machos y 5 indeterminados) de tres categorias etarias (sub adultos, adulto y macho adulto reproductor), los cuales fueron capturados durante los meses de noviembre y diciembre del año 2014. Los caimanes fueron capturados a la orilla del río Madre de Dios y se obtuvo una muestra sanguínea mediante punción de la rama dorsal de la vena cava craneal, realizándose 02 frotices sanguíneos que fueron fijados con metanol. Las láminas fueron depositadas y almacenadas para su posterior análisis. En el Laboratorio Central de la Facultad de Ciencias Agropecuarias de la Universidad Alas Peruanas se tiñeron las láminas ...

The aim of this study was to determine the presence of Hepatozoon sp in free-living spectacled caiman (Caiman crocodilus) in Bajo Madre de Dios, located in the department of Madre Dios, Peru. Blood samples were taken from 30 individuals (21 males, 4 females, 5 of undetermined sex) from three age categories (sub-adult, adult and reproductive active adult). The alligators were captured on the bank of the Bajo Madre de Dios river. Two smears per sample were prepared, fixed with methanol and stained with May-Grunwald Giemsa. The biometric measurements of the gametocytes, both intra and extra-erythrocytic were determined, confirming their correspondence with the genus Hepatozoon. The results showed that 90% (27/30) of the individuals were positive for Hepatozoon sp, being 100% females (4/4), 95.2% (20/21) of males and 60.0% (3/5) of undetermined sex.
