DETECTION OF COPATHOGENS IN FREE-RANGING EASTERN BOX TURTLES (TERRAPENE CAROLINA CAROLINA) IN ILLINOIS AND TENNESSEE
2017
Abstract Conservation efforts are investigating the impact of diseases within a species of interest, including prevalence and transmission and morbidity and mortality rates. However, the majority of these studies focus solely on the characteristics of a single pathogen. Recently, the role of copathogens has been reported to impact disease susceptibility and mortality. To that effect, a survey was conducted including 318 eastern box turtles (Terrapene carolina carolina) from populations in Illinois and Tennessee in 2014 and 2015. Blood samples and oral swabs were collected for quantitative polymerase chain reaction (qPCR) of 15 different pathogens performed in a multiplex format using Fluidigm array technology. Four pathogens were found with varying qPCR prevalence: ranavirus (FV3; n = 2, 0.6%), Terrapene herpesvirus 1 (TerHV1; n = 129, 40.7%), box turtle Mycoplasma sp. (BT Myco; n = 14, 4.6%), and box turtle adenovirus (BT Adv1; n = 18, 11%). Thirteen pathogens were not identified in any sample, including...
