Abstract

Background

Liver injuries are among the most common and can have a major impact on primates' health. This study aimed to describe the occurrence and frequency of hepatobiliary morphological changes in wild and human-cared non-human primates from the state of Rio Grande do Norte, Brazil.

Methods

Histological slides from 37 specimens of common marmosets (Callithrix jacchus), obtained from the Primatology Center at the Federal University of Rio Grande do Norte and the Wildlife Rescue Center of Rio Grande do Norte (CETAS-RN), were analyzed.

Results

In animals under human care, alterations consistent with parasitism by Platynosomum sp. were predominant, whereas in wild animals, lesions compatible with necrosis, inflammation, and degeneration occurred more frequently.

Conclusion

Among the most significant findings was parasitic infection caused by Platynosomum sp., present in both captive and wild animals, which in some cases caused chronic liver damage in animals that died without showing clinical signs.

野生和人工饲养条件下枸芪的肝脏病理和解剖病理特征

肝损伤是最常见的疾病之一，可对灵长类动物的健康产生重大影响。本研究旨在描述来自巴西北部大州的野生和人类照料的非人灵长类动物肝胆形态学变化的发生和频率。方法对37只普通狨猴（Callithrix jacchus）标本的组织学切片进行分析，切片取自北巴西联邦大学灵长类学中心和北巴西联邦大学野生动物救援中心（CETAS-RN）。结果在人类照料的动物中，与寄生一致的改变占主导地位，而在野生动物中，与坏死、炎症和变性相适应的病变更常见。结论最重要的发现是圈养动物和野生动物中均存在由Platynosomum sp.引起的寄生虫感染，在某些情况下导致动物慢性肝损伤，无临床症状死亡。
