All actinomycetes isolated from canal water, Ismailia water plant and tap water were identified into 5 genera. All Nocardia isolates were identified into 3 species. Two of which, Nocardia transvalensis and Nocardia otitidus-caviarus were recorded in tap water. These species are pathogenic for human kind and animals. The pathogenicity of these isolates was tested on Swiss Albino mice. Symptomatic changes and death of mice inoculated with Nocardia suspension were recorded. The main symptoms were erythema, enduration and inflammation together with abcesses and an increase in the size of the spleen (spleenomegally). It is concluded from these experiments that: i) All Nocardia species isolated from tap water are pathogenic, at least for mice, ii) these isolates could present health hazards to human kind and needs an urgent investigation.
从运河水、伊斯梅利亚水厂水和自来水中分离出的所有放线菌被鉴定为5个属。所有诺卡氏菌分离株被鉴定为3个种。其中两种，即南非诺卡氏菌和耳-鱼子诺卡氏菌在自来水中被检测到。这些菌种对人类和动物具有致病性。对这些分离株的致病性在瑞士白化小鼠身上进行了测试。记录了接种诺卡氏菌悬液的小鼠的症状变化和死亡情况。主要症状为红斑、硬结、炎症以及脓肿和脾脏肿大。从这些实验得出以下结论：i）从自来水中分离出的所有诺卡氏菌种都具有致病性，至少对小鼠是这样；ii）这些分离株可能对人类健康构成危害，需要立即进行调查。
