Transmission and course ofTrichophyton erinaceiinfections in British hedgehogs

Abstract
Observations on cross infection by Trichophyton erinacei in captive and wild hedgehogs indicate that the fungus is not highly pathogenic. A healthy animal may be exposed to an infected one for some months before itself becoming infected. Infected animals may remain free of lesions for long periods, but the disease eventually increases in extent and severity. No case of regression of infection or of recovery was noted. Possible means of transmission of the fungus are considered, and it is suggested that bodily contact, especially during fights, is the most likely means of cross infection. Low body temperature and reduction of movement during hibernation are both likely to slow down the progress of the disease and reduce the chances of cross infection.
