Case of the Month

Under the Microscope

Dr. Nicole Stacy, Adjunct Professor, kicks off our new series called “Under the MIcroscope”. Dr. Stacy joined our laboratory in 2016. She has given us a huge amount of advice and training in hematology and chemistry of reptile, elasmobranch, teleost, and marine mammal species. You can see her input in several new panels. She is an avid collaborator on many of our research studies. In addition, Dr. Stacy is available for clinical case consultation.

Abnormal Heterophil Morphology and Increased SAA Concentrations in a Cold-Stunned Florida Manatee During Rehabilitation from Dr. Nicole Stacy

Impressive toxic heterophils and a high serum amyloid A (SAA) level is found in a cold stunned manatee. Following the CBC and SAA had key prognostic value during the 4 months of rehabilitation.

Prominent Erythroid Regeneration in a Green Turtle (Chelonia mydas) from Dr. Nicole Stacy

Erythroid regeneration in reptiles can be prominent and early stage precursors may be observed in the peripheral blood. These round early stage precursors need to be identified correctly in the hemocytometer and by blood film evaluation, since they may be misinterpreted as lymphocytes or as leukemic cells of lymphoid, myeloid, or erythroid origin. These morphologic changes in the erythroid cell line are best interpreted in context of other hematological and biochemical data as well as clinical findings.

Bacilli in a Blood Film from a Common Emerald Dove (Chalcophaps indica) from Dr. Nicole Stacy

Only a small volume of blood was obtained but it was sufficient to make a blood smear. The right treatment was initiated from a review of the leukogram which featured distinct bacilli.

From the Lab Bench

Dr. Carolyn Cray continues the line of the Case of the Month series with impressive cases from the clinical laboratory. Dr. Cray is the Associate Director of the Avian & Wildlife Laboratory and is pleased to been part of the group that originated the laboratory in 1993. Her research interests include Encephalitozoon cuniculi, aspergillosis and acute phase proteins.

CRP as a Prognostic Indicator in a Rabbit with Suspected Encephalitzoon cuniculi infection from Dr. Carolyn Cray

Impressive IgM and IgG titers as well as an elevated C-reactive protein (CRP) were observed in the initial evaluation of a rabbit with head tilt and ataxia. Antibody titers are quite long lived but the CRP level decreased with clinical improvement.

Is It Really Albumin? from Dr. Carolyn Cray

Quantitation of albumin is tricky in many species. The reagent used on chemistry analyzers cross reacts with globulins in birds and reptiles. Protein electrophoresis provides the only valid result while also giving a bigger picture of the acute phase response.

From the Clinics

Dr. Lauren Thielen continues the Case the Month series with the Doxycycline Sensitive Macaw. Dr. Thielen joined our laboratory service in 2017. She is available for consultations to all of our veterinary clients.
