97例丝虫性乳糜尿病人13年后的转归调查

苍山县芹堂乡原为班氏丝虫病的高度流行区，丝虫性乳糜尿发病率较高。对1985年确诊的97例丝虫性乳糜尿病人进行13年后的转归调查，其年平均病死率为1．9％。，现症乳糜尿病人的病死率明显高于非现症乳糜尿病人，有非常显著性差异（P＜0．01）。死亡病人中男性明显高于女性（P＜0．01）。现症和非现症乳糜尿之间交替现象存在着非常显著性差异（P＜0．01）。

The Epidemiological Study on Human Streptococcal Infectious Syndrome Caused by Infected Pigs

Objective:To research the pathogeny and prevail factor of the manifestations of S. suis infective syndrome; to provide gists for treatment and control and prevent. Methods: 26 cases with the human streptococcal infective syndrome were identified. A 1:4 matched case-control study was carried out and the cause of disease pathogeny was severed and cultivated to identify fungus.The human born strains and the pig born strains were compared with RAPD technique. Results: The human case of streptococcal infective syndrome were found epidemiologically to be contracted by contacting with the infected pigs or infected pig corpses in Rugao and region borolering upon, with OR of 40.89.The strains of streptococcus isolated from the blood and cerebropinal fluid(CSF) of infective men were S. suis type 2 by biochemical tests and analysis of fatty acid of thalli and serum coagulate tests.The study of epidemiology proved that this disease wasn't infective among human.The strains of streptococcus from human and pigs were isogenous by RAPD techique. Conclusions:The case was caused by S. suis type 2 from contacting with the infected pigs or infected pig corpses.
