Snake Fungal Disease Caused by the Fungal Pathogen Ophidiomyces ophidiicola in Texas

Abstract

The pathogen Ophidiomyces ophidiicola (O.o.), widely known as the primary cause of snake fungal disease (SFD) has been detected in Texas’s naïve snakes. Our team set out to begin to characterize O. ophidiicola’s spread in east Texas. From July 2019 until October 2021, we sampled 176 snakes across east Texas and detected 27 positives cases (qPCR confirmed 27/176). From a ribbon snake with clear clinical display, we isolated and cultured what we believe to be the Texas isolate of O. ophidiicola. With over 1/10 snakes that may be infected in East Texas, gives credence to the onset of SFD in Texas.
