Use of a molecular approach for the definitive diagnosis of proliferative larval mesocestoidiasis in a cat

Abstract

A 9 year-old male, neutered cat with a history of a sudden onset of lethargy, anorexia and respiratory distress was presented in a veterinary practice in Lucca, Italy. A clinical examination revealed that the cat was severely dehydrated, and had pale mucous membranes and tachypnoea. No pain or discomfort was detected at the time of physical examination.
