Resumen: "Ticks are common ectoparasites of amphibians and reptiles but very few reports of
such parasites on crocodylians exist worldwide. Herein, we report the first detailed observations
of Amblyomma dissimile Koch, 1844 on the 3 crocodylian species present in Mexico, with the first
report of tick parasitism on Crocodylus acutus and the second on Caiman crocodilus chiapasius.
This is also the first report of A. dissimile in the state of Quintana Roo. Proportions of infested individuals
found in this study ranged from 0.51 to 1.96%, suggesting that tick parasitism in crocodylians
is likely opportunistic and occurs when individuals leave the water for terrestrial activities.
Tick parasitism does not represent a major threat to crocodylians. The increasing habitat destruction/
fragmentation and cattle expansion in southeastern Mexico, however, could increase tick
populations and trigger tick parasitism and tick-borne diseases in herpetofauna and other vertebrates,
including humans. Thus, studies are needed to better understand these relationships."
