Given the fact that numerous microbial species can be detected in pregnant female dogs, the objective of this study was to assess the transplacental transmission of Brucella canis, Ehrlichia canis, Neospora caninum and Toxoplasma gondii in stillborn puppies. This study involved 41 stillborn puppies, 78.6% of which were positive for T. gondii, 52.4% for N. caninum and 59.5% for B. canis. E. canis was not detected in any of the analyzed puppies. Pregnancy is an important physiological condition for the transmission of infectious agents to puppies and transplacental transmission may be epidemiologically relevant in the spread of these opportunistic agents.
鉴于在怀孕母犬中可检测到众多微生物种类，本研究的目的是评估犬布鲁氏菌、犬埃立克体、犬新孢子虫和刚地弓形虫在死产幼犬中的经胎盘传播情况。本研究涉及41只死产幼犬，其中78.6%的幼犬弓形虫检测呈阳性，52.4%的幼犬犬新孢子虫检测呈阳性，59.5%的幼犬犬布鲁氏菌检测呈阳性。在所分析的幼犬中未检测到犬埃立克体。怀孕是感染因子向幼犬传播的重要生理条件，经胎盘传播在这些机会性病原体的传播中可能具有流行病学意义。
