Amblyomma testudinarium tick bite: one case of engorged adult and a case of extraordinary number of larval tick infestation.

This paper reports two recent cases of tick bite due to Amblyomma testudinarium. The first case was an 86-year-old farmer infested with a fully engorged adult tick attached on his inguinal region. The second case was a 57-year-old male infested with an extraordinarily large number of larval ticks (> 100 larvae). The ticks were identified as A. testudinarium based on morphological characteristics. To our knowledge, the latter case is the eleventh case of larval tick bites among all tick species and the fourth case with larval A. testudinarium in Japan.
