Haematological changes and anaemia associated with captivity and petroleum exposure in seabirds

Haematological changes and anaemia associated with captivity and petroleum exposure in seabirds Free-ranging marine birds are severely impacted by petroleum released into the environment. Although petroleum can affect many organ systems, oxidative damage to red blood cells (RBC) and development of Heinz body anaemia is the only known mechanism of RBC damage in oil-exposed marine birds. Rhinoceros auklets (Cerrorhinca monocerata) were orally exposed to 0, 2.5 or 10 ml of Prudhoe Bay crude oil/kg body weight for five consecutive days by gavage tube. No statistically significant differences between treatment groups were evident for the following blood parameters: packed cell volume (PCV); haemoglobin concentration (Hb); mean corpuscular haemoglobin concentration (MCHC); reticulocyte percentage: fibrinogen concentration; white blood cell count (WBC); and cell counts of heterophils, lymphocytes, monocytes, eosinophils and basophils. After petroleum exposure, blood samples from auklets did not have any evidence of haemolysis, oxidative RBC damage or Heinz body formation as determined by new methylene blue staining of blood smears. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Comparative Clinical Pathology Springer Journals

Abstract

Free-ranging marine birds are severely impacted by petroleum released into the environment. Although petroleum can affect many organ systems, oxidative damage to red blood cells (RBC) and development of Heinz body anaemia is the only known mechanism of RBC damage in oil-exposed marine birds. Rhinoceros auklets (Cerrorhinca monocerata) were orally exposed to 0, 2.5 or 10 ml of Prudhoe Bay crude oil/kg body weight for five consecutive days by gavage tube. No statistically significant differences between treatment groups were evident for the following blood parameters: packed cell volume (PCV); haemoglobin concentration (Hb); mean corpuscular haemoglobin concentration (MCHC); reticulocyte percentage: fibrinogen concentration; white blood cell count (WBC); and cell counts of heterophils, lymphocytes, monocytes, eosinophils and basophils. After petroleum exposure, blood samples from auklets did not have any evidence of haemolysis, oxidative RBC damage or Heinz body formation as determined by new methylene blue staining of blood smears.
