In an effort to fill this gaping hole in our knowledge of donkey penises and microbiology, they cultured bacterial flora from prepubertal, mature intact, and castrated donkeys. Read on for the titillating results!Bacterial and fungal microflora on the external genitalia of male donkeys (Equus asinus) "This study was undertaken to investigate the bacterial and fungal microflora on the external genitalia of a population of healthy male donkeys in the state of Michigan, USA. The aim was to identify and determine the frequency of occurrence of these microorganisms using seven different isolation media and standard microbiological procedures.
