Pythiosis, lagenidiosis, and zygomycosis in small animals

A Case of Feline Gastrointestinal Eosinophilic Sclerosing Fibroplasia Associated with Phycomycetes

“…Based on the morphology of these fungi, the differential diagnosis included zygomycosis, pythiosis and lagenidiosis (Grooters, 2003;Rakich et al, 2005). These diseases are caused by phylogenetically diverse groups of pathogens, which share similar clinical and microscopical characteristics, making them difficult to distinguish (Grooters, 2003).…”

“…These diseases are caused by phylogenetically diverse groups of pathogens, which share similar clinical and microscopical characteristics, making them difficult to distinguish (Grooters, 2003). Because of their similarity, the term 'phycomycosis' is used when the diagnosis is not confirmed by culture or molecular techniques (Grooters, 2003).…”

While zygomycetes are considered true fungal organisms, members of genus Phytium and Lagenidium are currently included within the class Oomycetes, and are more closely related to algae than fungi (Grooters, 2003).…”

In the present case, the microscopical characteristics of the hyphae, together with the fact that they stained with HE, PAS and GMS, strongly suggested the diagnosis of zygomycosis (Grooters, 2003;Chayakulkeeree et al, 2006).…”

Unfortunately, specimens were not collected for culture because the lesions were presumed to be neoplastic at the time of gross examination.…”
