Prevalence of Linguatula serrata in domestic ruminants in South India.

ABSTRACT

Linguatula serrata Frohlich, 1789 is an aberrant endoparasite of occasional zoonotic importance in humans. We report the prevalence of encapsulated nymphal stages of L. serrata in domestic ruminants surveyed in Wayanad, located in Kerala State, South India. Large and small intestine mesentery were examined from 100 goats, cattle and buffaloes each revealing an infection prevalence of 21, 19, and 8%, respectively. The prevalence of L. serrata infection among ruminants is higher than previous reports from India and indicates a strong focus of infection in herbivorous domesticated mammals of South India. The potential importance of these findings to human health is discussed.
