ACUTE PHASE PROTEIN AND PROTEIN ELECTROPHORESIS VALUES FOR CAPTIVE GRANT'S ZEBRA ( EQUUS BURCHELLI)
Grant's zebra (Equus burchelli) are commonly kept in zoos and are subject to routine health monitoring and research studies. Recently, assays for acute phase proteins (APP) have been described in many wildlife species, and specific assays for serum amyloid A (SAA) have been well validated and studied in horses (Equus ferus caballus), in which it serves as a major APP. In the present study, serum samples from 26 Grant's zebra were subject to analysis by using assays for SAA, haptoglobin (HP), and protein electrophoresis. Reference intervals were calculated by using the robust method: SAA 1.8-31.4 mg/L and HP 0.37-1.58 mg/ml. Significant differences in SAA and HP were observed in clinically abnormal zebra; in some cases, these differences were marked and were noted in the absence of abnormal values for protein electrophoretic fractions. These data indicate that APP may be a valuable and sensitive tool in monitoring inflammation in this species

ASSESSMENT OF CAPILLARY ZONE ELECTROPHORESIS AND SERUM AMYLOID A QUANTITATION IN CLINICALLY NORMAL AND ABNORMAL SOUTHERN WHITE RHINOCEROS (CERATOTHERIUM SIMUM SIMUM) AND SOUTHERN BLACK RHINOCEROS (DICEROS BICORNIS MINOR).
Capillary zone electrophoresis (CZE) and an immunoassay for serum amyloid A (SAA) were used to examine serum samples from clinically normal and abnormal southern white rhinoceros (Ceratotherium simum simum) and southern black rhinoceros (Diceros bicornis minor) under managed care. CZE resolved seven fractions as well as subfractions for α1 globulins. Reference intervals were calculated for white rhinoceros (n = 33) and found to have some differences over previously reported intervals generated using agarose gel electrophoresis (AGE) methods in sera from free-ranging animals. In addition, the coefficient of variation related to fraction quantitation was found to be overlapping or superior to that reported for AGE. No significant differences were observed in CZE measurands and total protein between clinically normal and abnormal rhinoceros. In contrast to CZE, significant differences in SAA levels (P < 0.001) were observed in samples from the white rhinoceros between clinically normal and abnormal animals. In addition, in limited sample sets with repeated measures, SAA provided prognostic value. Future studies should generate more robust reference intervals and delineate the application of both SAA quantitation and CZE in routine health assessments and in prognostication

DEVELOPMENT OF A CASE DEFINITION FOR CLINICAL FELINE HERPESVIRUS INFECTION IN CHEETAHS ( ACINONYX JUBATUS

Epidemiology of clinical feline herpesvirus infection in zoo-housed cheetahs (Acinonyx jubatus).
OBJECTIVE To determine the incidence of and risk factors for clinical feline herpesvirus (FHV) infection in zoo-housed cheetahs and determine whether dam infection was associated with offspring infection. DESIGN Retrospective cohort study. ANIMALS 144 cheetah cubs born in 6 zoos from 1988 through 2007. PROCEDURES Data were extracted from the health records of cheetahs and their dams to identify incident cases of clinical FHV infection and estimate incidence from birth to 18 months of age. Univariate and multivariable Cox proportional hazards models, controlling for correlations among cheetahs with the same dam, were used to identify risk factors for incident FHV infection. RESULTS Cumulative incidence of FHV infection in cheetah cubs was 35% (50/144). No significant association between dam and offspring infection was identified in any model. Factors identified as significant through multivariable analysis varied by age group. For cheetahs up to 3 months of age, the most important predictor of FHV infection was having a dam that had received a preparturition FHV vaccine regimen that included a modified-live virus vaccine versus a dam that had received no preparturition vaccine. Other risk factors included being from a small litter, being born to a primiparous dam, and male sex. CONCLUSIONS AND CLINICAL RELEVANCE This study provided the first population-level characterization of the incidence of and risk factors for FHV infection in cheetahs, and findings confirmed the importance of this disease. Recognition that clinical FHV infection in the dam was not a significant predictor of disease in cubs and identification of other significant factors have implications for disease management
