Helminths and protozoan parasites in common opossums (Didelphis marsupialis) in a suburban area in Medellín, Colombia.

Didelphis marsupialis is a marsupial species that effectively adapts to synanthropic processes developing in cities. This marsupial lives closely with domestic animals and humans, which has favored the active exchange of parasites, thus increasing polyparasitism. Hence, this study aimed to determine the prevalence of helminths and protozoans infecting D.
