Whole‐mitochondrial genomes of Nannizziopsis provide insights in evolution and detection

Abstract

Abstract Infectious fungal diseases can have devastating effects on wildlife health and a detailed understanding of the evolution of related emerging fungal pathogen along with the ability to detect them in the wild is considered indispensable for effective management strategies. Several fungi from the genera Nannizziopsis and Paranannizziopsis are emerging pathogens of reptiles and have been observed to cause disease in a wide range of taxa. Nannizziopsis barbatae has become a particularly important pathogen of Australian reptiles with an increasing number of herpetofauna being reported with cases of infection from across the country. Here, we present the mitochondrial genome sequences and phylogenetic analysis for seven species in this group of fungi uncovering new information on the evolutionary relationship of these emerging pathogens. From this analysis, we designed a species‐specific qPCR assay for the rapid detection of N. barbatae and demonstrate its application in a wild urban population of a dragon lizard.
