Like in many other African countries, pig production is increasing in Tanzania. To support farmers and stakeholders, it is important to increase our understanding of porcine pathogens present in the country. Currently, little is known about the circulation of porcine circovirus-2 (PCV-2) and porcine circovirus-3 (PCV-3). For this reason, samples from 124 pigs collected throughout the country between 2018 to 2022 were screened by PCR for the presence of PCV-2 and PCV-3. Sequencing and phylogenetic analysis of positive amplicons identified two PCV-2 genotypes (a and d). Limited genetic heterogenicity was observed among the PCV-3. This study provides important data on pathogens present in pigs in Tanzania and should be of use veterinary authorities involved in porcine disease management.
和许多其他非洲国家一样，坦桑尼亚的养猪业正在发展。为了支持农民和利益相关者，我们需要提高对该国存在的猪病原体的认识。目前，人们对猪圆环病毒 2 型（PCV-2）和猪圆环病毒 3 型（PCV-3）的循环情况知之甚少。出于这个原因，2018 年至 2022 年间从全国各地采集的 124 份猪样本通过 PCR 进行了 PCV-2 和 PCV-3 的检测。对阳性扩增子进行测序和系统进化分析，确定了两种 PCV-2 基因型（a 和 d）。PCV-3 之间观察到有限的遗传异质性。本研究提供了关于坦桑尼亚猪中存在的病原体的重要数据，应该对参与猪病管理的兽医当局有用。
