History

A 21-year-old 0.67-kg (1.47-lb) sexually intact female Indian flying fox (Pteropus giganteus) born and housed at the Baton Rouge Zoo was brought to the zoo's veterinary hospital because of lethargy, a perceived decreased desire to forage for food, and a generally poor state of well-being.

Clinical and Gross Findings

An initial physical examination was performed when the bat was awake and subsequently when it was anesthetized with isoflurane. The bat had grade IV/IV periodontal disease and was obese. Serum biochemical analysis revealed no notable abnormalities. The bat had an excellent appetite when hand fed but would not

Abstract

OBJECTIVE

To evaluate the agreement between 3 point-of-care (POC) devices and a reference laboratory for measuring β-hydroxybutyrate (β-HB) concentration in African penguin (Spheniscus demersus) whole blood (WB) and plasma samples and the precision of each POC device for measuring β-HB concentration in plasma samples.

ANIMALS

48 healthy African penguins.

PROCEDURES

Blood was obtained from the right jugular vein of each penguin, and β-HB concentration was measured on each POC device using fresh WB and heparinized plasma and at the reference laboratory using plasma. β-HB concentration was measured in plasma on each POC device.

RESULTS

All devices overestimated serum β-HB concentrations on average by 0.46 mM relative to the reference laboratory. WB samples had less error than plasma for meters A and C. Meter A had the lowest total error observed (26.4%) and the lowest mean difference (0.19 mmol/L) relative to the reference laboratory. Controlling for other factors, the magnitude of disagreement was not affected by sex, age, packed cell volume, or serum total solids concentration.

CLINICAL RELEVANCE

WB, not plasma, should be used for measurement of β-HB concentration on the POC meters tested. Meter A showed good correlation with the reference laboratory for WB. The use of POC devices for the measurement of β-HB concentration may be acceptable when laboratory analyzers are not available. Further research is needed for clinical application and the diagnostic value of POC meters compared with reference laboratories.

History

A 16-year-old 7.8-kg (17.16-lb) sexually intact female serval (Leptailurus serval) housed at the Baton Rouge Zoo was evaluated at the zoo's veterinary hospital because of recurrent hematuria, pollakiuria, and intermittent anorexia of several weeks' duration.

Clinical, Clinicopathologic, and Gross Findings

Over a 6-month period, the hematuria became refractory to treatment. Urinalysis performed on a free-catch urine sample revealed a urine specific gravity of 1.014, 1+ proteinuria, 3+ blood, 25 to 50 RBCs/low power field (10X), and 1 to 3 WBCs/low power field (10X). Examination of a cytospin preparation of urine sediment revealed 1 to 3 epithelial cells/hpf
