Listeria monocytogenes, isolated from outbreaks in either human or nonhuman primate populations, was administered orally at doses ranging from 10(6) to 10(10) CFU. Four of 10 treated animals delivered stillborn infants. L. monocytogenes was isolated from fetal tissue, and the pathology was consistent with L. monocytogenes infection as the cause of pregnancy loss. For all pregnancies resulting in stillbirths, L. monocytogenes was isolated from maternal feces, indicating that L. monocytogenes had survived and had probably colonized the gastrointestinal tract. Antibodies and antigen-specific lymphocyte proliferation against Listeria increased in animals that had stillbirths.
从人类或非人灵长类动物群体的疫情中分离出的单核细胞增生李斯特菌,经口服给药,剂量范围为10⁶至10¹⁰CFU。10只接受治疗的动物中有4只产下死胎。从胎儿组织中分离出单核细胞增生李斯特菌,病理学检查结果与单核细胞增生李斯特菌感染导致流产相符。对于所有导致死产的妊娠,均从母体粪便中分离出单核细胞增生李斯特菌,这表明单核细胞增生李斯特菌存活下来并可能在胃肠道定植。死产动物体内针对李斯特菌的抗体和抗原特异性淋巴细胞增殖增加。
