Infestation by Haematopinus quadripertusus on cattle in São Domingos do Capim, state of Pará, Brazil.
Severe infestation with lice was observed on crossbred cattle (Bos taurus indicus ×Bos taurus taurus) in the municipality of São Domingos do Capim, state of Pará, Brazil. Sixty-five animals were inspected and the lice were manually collected, preserved in 70% alcohol and taken to the Animal Parasitology Laboratory, School of Veterinary Medicine, Federal University of Pará, Brazil, for identification. The adult lice were identified as Haematopinus quadripertusus, and all the cattle examined were infested by at least one development stage of this ectoparasite. The specimens collected were located only on the tail in 80% (52/65) of the cattle, while they were around the eyes as well as on the ears and tail in 20% (13/65). Nits, nymphs and adults of the parasite were respectively collected from 98.46% (64/65), 38.46% (25/65) and 23.08% (15/65) of the animals examined. This is the first report of bovine pediculosis caused by H. quadripertusus in the state of Pará, Brazil. Further studies should be conducted to determine the occurrence pattern of this species in Brazil and its importance to livestock production.
