Serovars of a total of 5,490 Salmonella strains isolated during the period of 1991-95, from human infections (2,254 strains) and from non-human materials (3,236 strains) were evaluated. In the studied period, 81 different serovars were determined among human isolates. Salmonella Enteritidis corresponded to 1.2% in 1991, 2% in 1992, 10.1% in 1993, 43.3% in 1994, and 64.9% in 1995 of all isolates. A significant rise on the isolation of this serovar was seen since 1993 linked to food poisoning outbreaks. It is reported also an increase on the isolation of S. Enteritidis from blood cultures, associated mainly with patients with immunodeficiency syndrome. S. Enteritidis was prevalent among one hundred and thirty different serovars isolated from non-human sources. Increasing number of isolation of this serovar was seen from shell eggs, breeding flocks and from environmental samples. It is also reported a contamination of commercial feed stuffs by S. Enteritidis which represents a major concern for Brazilian poultry industry.
对1991年至1995年期间分离出的总共5490株沙门氏菌菌株的血清型进行了评估，这些菌株来自人类感染（2254株）和非人类来源（3236株）。在研究期间，在人类分离株中确定了81种不同的血清型。肠炎沙门氏菌在1991年占所有分离株的1.2%，1992年占2%，1993年占10.1%，1994年占43.3%，1995年占64.9%。自1993年以来，与食物中毒暴发相关，该血清型的分离率显著上升。还报告了从血培养中分离出肠炎沙门氏菌的情况增加，主要与免疫缺陷综合征患者有关。肠炎沙门氏菌在从非人类来源分离出的130种不同血清型中占优势。从带壳蛋、种鸡群和环境样本中分离出该血清型的数量不断增加。还报告了肠炎沙门氏菌对商业饲料的污染，这是巴西家禽业的一个主要担忧。
