摘要
采用国标 (GB4789 2 8- 84)的检验方法 ,对 4450份猴粪便检测 ,检出志贺氏菌 1 72株 ,阳性检出率 3 9%。取其中 50株做血清学分型 ,皆属于B群志贺氏菌 ,主要血清型为 3c型 32株 (占64% )、Y变种 1 2株 (占 2 4 % )、其次 4b型 3株、X变种 2株、2a型 1株 (分别占 6%、4%、2 % )。以此 50株福氏志贺氏菌对 1 0种抗菌素作了敏感度及抑菌效果评价 ,结果丁胺卡那霉素及先锋霉素V敏感度为1 0 0 % (高度敏感 ) ,庆大霉素高敏者只占 44%、耐药者占 56% ,而对氯霉素中、高敏者占 88% ,氟哌酸中、高敏者占 82 %。B群志贺氏菌对氟哌酸、庆大霉素已分别有 1 8～ 56%的菌株产生了耐药性。本文首次报道了广西食蟹猴群志贺氏菌 3c型和Y变种两菌型是目前引起猴腹泻、痢疾的主要血清型 ,同时也证实了少数无临床症状 。
? 172 strains of Shigella were isolated from feces of 4450 monkeys with GB 4789.28-84 method, the positive rate was 3.9%. the positive 50 S of with serology classification, belonged to B group of Shigella. 32 of the positives(64%) were 3c type and 12 of them (24%) were Y type, 3 of them were 4b, 2 of them were X type and 1 of them was 2a. All the 50 strains were tested with 10 antibiotics for effect and sensitivity. We found that Amikacinum, Cefamezin had high sensitivity. Gentamicinum only had 44% of high sensitivity, 56% of insensitivity. Both of middle and high sensitivity, Chloromycetin was 88% and Norflozacin was 82%. 15%-56% of B group of Shigella were insensitive to Norfloxacin and Gentamicinum. It was firstly reported that 3c and Y type of Shigella isolated from M. facicularis in Guangxi mainly resulted in diarhea and dysentery. It was also proved that the monkeys of normal feces and health characteristics with bacteria were the most dangerous and main resource of infection.
