Abstract

Bacterial densities of sewage from five hospitals in Baghdad city from September 1983 to August 1984 were measured.

The average numbers of total coliform, faecal coliform, faecal streptococci, Staphylococci, Klebsiella sp. and fluorescent Pseudomonas sp. were $20·94 × 10^{3}, 7·49 × 10^{2}, 8·00 × 10^{4}, 3·4 ×1o^{4}, 7·10 ¢ 10^{4}$ and 4·16 × 10⁵ cells ml⁻¹, respectively. A remarkable decrease was observed from December to March, as well as regular changes during other seasons, in the numbers of total coliforms, Kelbsiella sp. and fluorescent Pseudomonas. Faecal coliform, faecal streptococci and Staphylococci did not show such a profile. Specialised hospitals contained higher counts of total coliform than general hospitals.

Two Salmonella serotypes were identified—S. albany and S. senftenberg.

巴格达市医院污水的细菌密度

对1983年9月至1984年8月巴格达市5家医院污水中的细菌密度进行了测量。总大肠菌群、粪便大肠菌群、粪便链球菌、葡萄球菌、克雷伯氏菌和荧光假单胞菌的平均数量分别为20.94 × 103、7.49 × 102、8.00 × 104、3.4 ×1o4、7.10 × 104和4.16 × 105个细胞ml−1。从12月至3月，总大肠菌群、克尔伯氏菌和荧光假单胞菌的数量显著减少，其他季节也有规律变化。粪便大肠菌群、粪便链球菌和葡萄球菌没有这种特征。专科医院的总大肠菌群数量高于综合医院。鉴定出沙门氏菌两种血清型:s;奥尔巴尼和S. senftenberg。
