Internal helminth parasites are
potential causes of primary disease in dogs
and cats and zoonotic diseases in humans.
Canine and feline parasite surveys
frequently list roundworms (Toxocara
canis, Toxocara cati, Toxascaris leonina) and
hookworms (Ancylostoma caninum,
Ancylostoma tubaeforme, Ancylostoma
braziliense, Uncinaria stenocephala) as
common helminths. Numerous
anthelmintics, representing several
chemical classes, are available for
treatment and control of canine and feline
roundworm and hookworm infections.
