The Atlantic Forest is characterized by a high species diversity and endemism. This ecosystem is under human-induced threats for decades, loosing area to agriculture, pastures and urban areas.These threats have lead to habitat destruction and fragmentation, disturbing ecological processes and affecting the enzootic cycle of diseases. Didelphis aurita is an Atlantic Forest marsupial with synanthropic habit, capable of survive in disturbed and fragmented environments, including urban areas. The aim of this study was to describe haemoparasites, hematologic and serum chemistry aspects of D. aurita in Serra dos Órgãos/ RJ, comparing two areas, a conserved forest and a fragmented landscape. Between July 2011 and February 2012 61 specimens were studied. Results are given as mean ± standard deviation, as follows: Packed cell volume 38,66 % (± 4,97); erythrocytes 5,40 (± 0,75)x106/mm3; hemoglobin 12,78 (± 1,68) g/dL; MCV 71,69 (± 3,56) fl; MCHC 33,01 (± 0,63) %; Platelets 514,70 (± 323,10) x 103/mm3; Leukocytes 19.678,52 (± 10.152,26)/mm3; basophils 0,59 (± 0,72) %; eosinophils 13,79 (± 6,94)%; band neutrophils 0,77 (± 2,04) %; neutrophils 41,12 (± 13,95) %; lymphocytes 41,97 (± 12,97) %; monocytes 1,75 (± 1,51)%. The serum chemistry values were: total protein8,50 (± 1,68); albumin 3,03 (± 0,69); globulin 5,44 (± 1,66); BUN 83,57 (± 20,11); creatinine 0,44 (± 0,13); ALT 85,01 (± 65,65); AST 314,55 (± 130,58); AP 420,38 (± 371,89); GGT 19,40 (± 8,51). Packed cell volume, hemoglobin, erythrocytes, ALT, AST and AP were higher in males than in females. Adults have higher values of total plasmatic protein, leukocytes, packed cell volume, hemoglobin, erythrocytes, albumin, total protein and GGT than young animals. The Young have higher platelets, globulin and AP. Animals from the fragmented area present lower body mass and lower levels of albumin than those from the conserved Forest. The opposite occurred for GGT and globulin. Babesia sp. were found in 26.6% of specimens, more frequently in adults. These results are the very first reportof hematologic and serum chemistry values for D. aurita in Serra dos Órgãos.
