The incidence of Salmonella enteritidis infection has been study in order to determine their epidemic spread from 1983 to 1994, and the impact of the measures introduced to attempt its control.
Review of the stool cultures positives for enteric pathogens obtained in the Hospital de Navarra from 1983-1994.
Looking at the isolation rates of the different enteric pathogens from 1983 to 1994, a sharp increase of S. enteritidis was recorded on 1985 as a consequence of several outbreaks associated with the consumption of mayonnaise elaborated with row eggs. From 409 strains of Salmonella isolated that year, 302 were serotype enteritidis, this means a 7.5 fold rise since the preceding year in which the prevailing serotype was S typhimurium. From 1985 through 1991 the incidence of S. enteritidis stand high, and pick again on 1990. Since then, a decline has been observed, and in 1994 the number of Salmonella cases recorded were about those on 1984, however, S. enteritidis is now the prevailing serotype.
The egg-borne S. enteritidis epidemic emerged as a major public health problem in Navarra in 1995, associated to the consumption of home made mayonnaise. The measures introduced by local Public Health authorities to attempt control of non pasteurized mayonnaise were insufficient. Evidence from other places links human infections to vertical transmission from breeding flocks to layers. And makes of S. enteritidis infection an international challenge. The severity of the lived experience demands a time-temperature control of eggs in the interval from purchaser to consumer and a more generalized use of pasteurized egg products, no only in the industry but also in the household.
为了确定肠炎沙门氏菌感染的流行传播情况以及所采取的控制措施的影响，对1983年至1994年期间肠炎沙门氏菌感染的发病率进行了研究。
回顾1983年至1994年在纳瓦拉医院获得的肠道病原体粪便培养阳性结果。
观察1983年至1994年不同肠道病原体的分离率，1985年肠炎沙门氏菌的分离率急剧上升，这是由于几起与食用用生鸡蛋制作的蛋黄酱相关的疫情所致。当年分离出的409株沙门氏菌中，302株为肠炎血清型，这意味着自前一年流行血清型为鼠伤寒沙门氏菌以来增加了7.5倍。从1985年到1991年，肠炎沙门氏菌的发病率一直居高不下，并在1990年再次上升。从那时起，发病率有所下降，1994年记录的沙门氏菌病例数与1984年大致相同，然而，肠炎沙门氏菌现在是主要的血清型。
1995年，通过鸡蛋传播的肠炎沙门氏菌疫情在纳瓦拉成为一个主要的公共卫生问题，与食用自制蛋黄酱有关。当地公共卫生当局采取的控制未巴氏杀菌蛋黄酱的措施并不充分。其他地方的证据将人类感染与从种鸡群到蛋鸡的垂直传播联系起来。这使得肠炎沙门氏菌感染成为一项国际挑战。实际情况的严重性要求在从购买者到消费者的时间段内对鸡蛋进行时间-温度控制，并更广泛地使用巴氏杀菌蛋制品，不仅在工业中，而且在家庭中。
