The Salmonella Reference Centre in Johannesburg received 14059 strains of human origin between 1979 and 1984. A significant proportion (6.3%) proved to belong to subspecies II. The majority were cultured from faecal material, usually associated with symptoms related to the gastrointestinal tract. They comprised 884 isolates, represented by 203 serotypes, of which 45 were new serotypes. The poor hygienic conditions found in many rural areas, together with possible contamination of food and water by wild animals, may contribute to the greater frequency of human S.II infections and the widespread occurrence of unusual serotypes in man in this geographic region.
约翰内斯堡的沙门氏菌参考中心在1979年至1984年间收到了14059株源自人类的菌株。其中相当一部分（6.3%）被证明属于亚种II。大多数菌株是从粪便样本中培养出来的，通常与胃肠道相关症状有关。它们包括884株分离株，由203种血清型代表，其中45种是新血清型。许多农村地区卫生条件差，加上野生动物可能对食物和水造成污染，可能导致该地理区域人类感染沙门氏菌亚种II的频率更高，以及人类中不寻常血清型的广泛出现。
