Hematology and serum biochemistry reference intervals for the common opossum Didelphis marsupialis.

The common opossum, Didelphis marsupialis, is a neotropical and synanthropic marsupial common and widespread in Latin America. The strong human-opossum conflict that results in high numbers of individuals with health problems demands information on physiological parameters to be used in veterinary medicine practice. The aim of this study was to estimate the reference intervals (RI) of hematology and serum biochemistry for this species which are lacking and evaluate its variability.
