title: Bacterial infection in an Irrawaddy dolphin (Orcaella brevirostris).
abstract: One pregnant captive Irrawaddy dolphin (Orcaella brevirostris), with a body length of 225 cm, was found dead on 8 June 2009. The dolphin was anorexic and circling at the bottom of the pool before death. Laboratory tests revealed an increased leukocyte count and decreased platelet count; increased erythrocyte sedimentation rate; and slightly decreased red blood cell count, hemoglobin, and hematocrit. Alkaline phosphatase, creatinine, and glucose were significantly decreased. Moreover, uric acid and alanine aminotransferase and aspartate aminotransferase levels were elevated. A 57-cm fetus was recovered. The respiratory system, intestinal mucosa, mesentery and mesenteric lymph nodes, and spleen were congested and hemorrhagic. The heart, liver, and kidney appeared normal. Klebsiella spp. and Staphylococcus aureus were identified in the amniotic fluid. This is the first case report of bacterial infection in an Irrawaddy dolphin.
