Multicentric Malignant Lymphoma In A Pallid Bat, Claire B. Andreasen, Julie R. Dulmstra
Multicentric Malignant Lymphoma In A Pallid Bat, Claire B. Andreasen, Julie R. Dulmstra
Claire B. Andreasen
A 2.5-year-old, female pallid bat (Antrozous pallidus) was captured in Oregon (USA) in 1990 and later died in 1992. At the time of death, abdominal distension due to ascites, splenomegaly, and hepatomegaly, and a cheek mass were noted. Based on histologic examination of these tissues, a diagnosis of multicentric lymphoma was made. Retroviral particles were not found on electron microscopic examination.

Sera of 19 male and female bowhead whales (Balaena mysticetus) collected near Barrow, Alaska (USA) between 30 August and 13 October 1992 were evaluated for 18 serum chemistry values. Male bowhead whales had significantly greater creatinine and sodium concentrations, and significantly lower glucose concentrations than females. Pregnant females had greater triglyceride levels than non-pregnant females. The mean concentrations of creatinine, blood urea nitrogen, alkaline phosphatase, total bilirubin, total protein, sodium, potassium, chloride, phosphorus, and calcium were similar to those previously reported from bowhead whales. High aspartate aminotransferase and creatine kinase levels were attributed to muscle damage associated with harpooning.
Comparison Of The Effect Of Different Opsonins On The Phagocytosis Of Fluorescein-Labeled Staphylococcal Bacteria By Chicken Heterophils, Claire B. Andreasen, James R. Andreasen Jr., Anita E. Sonn, Julie A. Oughton
Comparison Of The Effect Of Different Opsonins On The Phagocytosis Of Fluorescein-Labeled Staphylococcal Bacteria By Chicken Heterophils, Claire B. Andreasen, James R. Andreasen Jr., Anita E. Sonn, Julie A. Oughton

Heterophil phagocytosis of fluorescein-labeled staphylococcal bacteria was analyzed by flow cytometry. Opsonization with two types of normal pooled sera and staphylococcal antisera significantly increased bacterial phagocytosis compared to samples without an opsonin. The staphylococcal antisera did not significantly increase bacterial phagocytosis compared to the normal pooled sera. Opsonization appears to increase bacterial phagocytosis but specific antisera may not increase phagocytosis beyond that caused by pooled normal sera.
