A two-step zero-length cross-linking procedure using active esters was successfully adopted for conjugating enrofloxacin (EF) to human serum albumin (HSA). The derived conjugate was characterized by UV spectrum and then used for immunization of BALB/C mice. In enzyme-linked immunosorbent assay (ELISA) and competitive inhibition ELISA experiments, the derived antiserum exhibited high antibody titer (greater than 1 : 250 000) as well as varied cross-reactivity (from 97.8% to 161.7%) to three analogs of EF belonging to fluoroquinolones family. But over the concentration range studied, no significant cross-reactivity was observed to other group of antibiotics (chloramphenicol, oxytetracycline, sulphamethoxazole and nysfungin). It was confirmed that the synthesized immunogen was highly antigenic and elicited specific antibody responses in BALB/C mice against EF. 相似文献

感染嗜水气单胞菌对鲫鱼非特异性免疫功能的影响 总被引:10,自引:0,他引:10
嗜水气单胞菌是淡水鱼流行性败血症的主要致病菌.文中通过试验用鲫鱼腹腔注射嗜水气单胞菌,在其染菌后不同时间取血,通过白细胞数量、NBT阳性细胞数量以及血清溶菌酶活力的变化趋势来研究感染病原菌对鱼类非特异性免疫功能的影响.结果表明,在鲫鱼感染嗜水气单胞菌后前3d内,白细胞数量、NBT阳性细胞数量以及血清溶菌酶活力依感染浓度不同,呈现先增加后降低的趋势.说明嗜水气单胞菌与鲫鱼非特异性免疫功能之间呈现一定的时间效应和浓度依赖性. 相似文献
