Intravenous Inoculation of Third-Stage Larvae of Metastrongylus spp. and Implantation Directly into Swine Lungs

Parenteral Infection of the Cat by Larvae of Aelurostrongylus abstrusus

“…It is known that pulmonary infections have been produced in calves by the subcutaneous administration of larvae of Dictyocaulus viviparus (Wade and Swanson, 1958), in pigs by the intravenous and intratracheal injection of Metastrongylus spp. larvae (Kelley & Krous, 1961) and in sheep by the intravenous inoculation of Dictyocaulus filaria larvae (Michel and Sinclair, 1963). As neither intravenous nor intratracheal administration is particularly desirable in cats, it was resolved to attempt the reproduction of lungworm disease in that species by the subcutaneous injection of third stage larvae of Aelurostrongylus abstrusus.…”
