When the diagnosis of parvovirus in dogs and cats becomes challenging.

Parvoviruses (PV) can cause outbreaks with high morbidity and mortality in dogs and cats. Even if typical cases exist in puppies and kittens, PV infection (PVI) can have many different clinical presentations, making the laboratory support necessary. The aim of this work was to evaluate retrospectively the frequency of misdiagnoses, particularly missed diagnoses, of PVI in 144 suspected cases (88 clinical cases and 56 necropsies) involving 96 dogs and 48 cats.
