Double anus in an Ixodes scapularis nymph, a medically important tick vector

Double anus in an Ixodes scapularis nymph, a medically important tick vector

Abstract Background Ixodes scapularis ticks are medically important arthropod vectors that transmit several pathogens to humans. The observations of morphological abnormalities, including nanism, missing leg, extra leg, and gynandromorphism, have been reported in these ticks. In this study, we repor...
