Title: Shell Lesions Associated with Emydomyces testavorans Infection in Freshwater Aquatic Turtles.       The purpose of this study was to identify shell lesions associated with the fungi E. testavorans in freshwater turtles and to describe the morphology of these lesions  (Woodburn, et al., 2021) .  Materials:      There were 50 specimens of freshwater and semi aquatic turtle species and species of turtle shells included in this study. The shells that were selected for this study had to have the layers associated with healthy tissue layers (i.e., keratin layer, epidermis, dermis, and the shell portion which is made up of bone). Partial shells were not included in this study. The free-living turtles for this study resided in Florida and Washington of the United States  (Woodburn, et al., 2021) .   Methods:      This study included three types of methods in order to identify lesions associated with E. testavora...

 The shell of a turtle is composed of a carapace and a plastron. The carapace is located dorsally, and the plastron is located ventrally. They are connected by a bridge on both sides ( Schoch & Sues., 2020 ). Figure 1: (a) dorsal view of carapace. (b) ventral view of carapace showing nine thoracic vertebrae. (c) stained specimen of the carapace in a young turtle (d) increased magnification of costal plates (Hirasawa et al., 2013) The carapace is made up of bony elements: the neural plates, costal plates, and peripheral plates. The neural plates are in the center line of the carapace, and they are attached to the vertebrae on the underside ( Schoch & Sues., 2020 ). The costal plates surround the neural plates and support the ribs (Schoch & Sues., 2020). The peripheral plates are located surrounding the costal plates. There is also a nuchal which is the anterior portion of the carapace (Figure 1). Figure 2: (a) Dissection of the surface layer of keratinized scutes.  ...
