In an effort to determine if bacterial water quality was related to the incidence of otitis externa ("swimmer's ear") in kindergarten children, a prospective study was conducted between May and September 1980 in 11 communal agricultural settlements (kibbutzim) in Israel. High total bacterial count, total coliforms and fecal coliform counts were found to be positively associated with otitis externa. This association was enhanced when nondivers were separated from divers. Among the divers, the rate of ear inflammation was high regardless of water quality. Among nondivers at the time of the study, the rate of otitis externa was as high as 35.7% in swimming pools with poor quality water, and as low as 17.0% in those with good quality water (P = 0.03). Younger children had a slightly higher risk of otitis externa than had older children.
为了确定幼儿园儿童的细菌性水质是否与外耳炎（“游泳者耳炎”）的发病率有关，1980年5月至9月在以色列的11个公共农业定居点（基布兹）进行了一项前瞻性研究。发现细菌总数、总大肠菌群和粪大肠菌群计数与外耳炎呈正相关。当非潜水者与潜水者分开时，这种关联增强。在潜水者中，无论水质如何，耳部炎症的发生率都很高。在研究期间，非潜水者中，水质差的游泳池中外耳炎的发生率高达35.7%，而水质好的游泳池中则低至17.0%（P = 0.03）。年幼儿童患外耳炎的风险略高于年长儿童。
