Prominent animal mycoses from various regions of the world

The mycoses selected for presentation in this section are relatively common diseases of companion animals or livestock in certain areas of the world. Malasseziosis is arguably the most frequent mycosis of dogs (as otitis exte rna and dermatitis) throughout the world, although its diagnosis is often o verlooked. Protothecosis is also geographically widespread, particularly in cattle where severe mastitis is a result of adventitious infection from th e environment. In contrast, coccidioidomycosis and pythiosis are geographic ally limited in their occurrence (coccidioidomycosis by geographic region a nd pythiosis by climate), but within regions where they do occur, their pre sence in animals is not unusual. It was our intention to review recent deve lopments in each of these diseases.
