In order to understand further about its natural character for Plesiomonas Shigelloides (Ps) and the disease caused by this bacterial genus, we reported a special studying about ecology of Ps. We tested 398 samples from different natural water 99 strains of Ps were isolated, the average positive rate is 24.87%, the highest positive rate is in sewage-water samples. The genus of Ps can be isolated in all seasons, this rate is more in summer than in winter, its rate in pig is 2.56%, duck 21.70%, fish of fresh-water 29.22%, decorative animal 32.35%. This study have proved that Ps has birds natural host. Its positive rate is 14.70% in all population, 13.15% in diarrhoea patient, there is no significance difference (chi 2 = 0.40 P greater than 0.05), between normal and diarrhea patients. Positive rate in rural is more than city, and children higher than adult. By all 50 O sera we found that 71.08%, strains was serotype however, they fell into 42 O ser-types.
为了进一步了解类志贺邻单胞菌（Ps）的自然特性及其所致疾病，我们报道了一项关于Ps生态学的专项研究。我们检测了来自不同天然水体的398份样本，分离出99株Ps，平均阳性率为24.87%，阳性率最高的是污水样本。Ps可在四季分离到，夏季的分离率高于冬季，在猪中的分离率为2.56%，鸭为21.70%，淡水鱼为29.22%，观赏动物为32.35%。本研究证明Ps有鸟类自然宿主。其在所有人群中的阳性率为14.70%，腹泻患者中为13.15%，正常人与腹泻患者之间无显著差异（χ2 = 0.40，P＞0.05）。农村的阳性率高于城市，儿童高于成人。通过所有50种O血清型检测发现，71.08%的菌株有型别，但它们分属于42种O血清型。
