They form adelophialides, but these conidiogenous cells show conspicuous collarettes and colonies usually are pink-salmon to dark brown.
Lecythophora are commonly involved in human AIDS-associated infections, often with a fatal outcome, following peritonitis, endocarditis, endophthalmitis and keratitis. As a species, they are poorly differentiated morphologically, are difficult to identify, and may be confused with poorly sporulating Fusarium spp.
Dogs are thought to become infected from ingesting or inhaling conidial spores while foraging, through skin wounds or when eating small amphibians and reptiles.
Lecythophora are an opportunistic pathogen that causes infections characterized by progressive granulomatous lesions in the subcutaneous tissues as well as disseminated visceral infections.
Species which are pathogenic to dogs include:
- Lecythophora hoffmannii
- Lecythophora mutabilis
Diagnosis can be ascertained by microscopic identification of the fungus or by PCR assay speciation. Lymph nodes characteristically contain PAS positive fungal elements and portions of tissue culture produce mycelial fungal growth.
