Red-bellied tamarins (Saguinus labiatus): Hematologic reference values and hemopathologic responses.

Area of Science:

• Veterinary Hematology
• Primate Medicine
• Comparative Pathology

Background:

• Establishing hematologic reference values is crucial for diagnosing diseases in captive exotic animals.
• Red-bellied tamarins (Saguinus labiatus) are increasingly kept in captivity, necessitating species-specific health data.
• Previous hematologic data for this species is limited.

Purpose of the Study:

• To determine normal hematologic and fibrinogen reference values for captive adult red-bellied tamarins (Saguinus labiatus).
• To compare hematologic findings in clinically normal tamarins with those in ill individuals.
• To provide a basis for diagnosing hematologic abnormalities in Saguinus labiatus.

Main Methods:

• Collected blood samples from 25 clinically normal, captive adult red-bellied tamarins.
• Performed complete blood counts (CBCs) and fibrinogen estimations.
• Analyzed data for sex-based differences and compared findings with nine clinical cases.

Main Results:

• Established reference ranges for red-bellied tamarin hematology and fibrinogen.
• Identified a higher reticulocyte count in female tamarins compared to males.
• Observed anemia, neutrophilia, and elevated fibrinogen in cases of self-inflicted injuries, dermatitis, and intussusception.
• Noted target cells and icteric plasma in yersiniosis; severe anemia and Heinz bodies in wasting cases.

Conclusions:

• The established reference values are valuable for diagnosing hematologic abnormalities in captive red-bellied tamarins.
• Hematologic changes observed in clinical cases correlate with specific diseases, including anemia, infections, and wasting syndromes.
• Findings provide a foundation for further research into tamarin health and disease.
