摘要
本文检测1854例急性腹泻患者粪便标本,从中分离出空肠弯曲菌165株,阳性率为8.9%。其中,儿童患者的阳性率(9.5%)高于成人患者(6.9%);农村患者的阳性率高于城市患者。在不同年龄患者中,以1～2岁和15～24岁年龄组的阳性率较高。对各月份阳性病例的统计表明,空肠弯曲菌感染性腹泻的发病高峰在夏秋两季。在正常及非腹泻人群中,空肠弯曲菌的带菌率为1.5%。检测158株空肠弯曲菌对九种常用抗菌药物的敏感性,以对 SMZco 和四环素产生耐药性的菌株较多。
Fecal specimens from 1854 cases of acute diarrhea patients were examined,from which 165 strains of C.iejuni were isolated.The total positive rate is 8.9%.The positive rate in the children(9.5%) is higher than that of the adults(6.9%),and the positive rate of the rural area is higher than that of the urban district.Higher rates are found in the'1—2'year and '15—24' year group when age groups are compared.The apices of occurrence were found in summer and autumn.The carrier rate in the normal individual and non—diarrhea group is 1.5%. In vitro susceptibility test of 158 strains against 9 antibioti- cs were carried out.Many strains were resistant to SMZco and tetracycline.
