Filiform papillae of Holstein heifer tongues and their relationship with Rhipicephalus (Boophilus) microplus infestation

Selma Marques D’Agostino, Fernanda Ferreira Pessoa, Luciandra Macedo de Toledo, Ricardo Lopes Dias da Costa et autres

Mammals’ self-cleaning behavior helps to reduce infestations of ectoparasites, especially ticks. We investigated the relationship between measurements of the filiform papillae of heifer tongues and tick infestation. To assess the papillae, biopsies were performed on the anterior surface of the tongues of …
