The incubation period for both can last from 7-10 days. The period of communicability is the first 3 weeks of illness.

白喉及百日咳的潜伏期均可持续7-10天，在发病后的3周内具有传染性。

Essential amino acid residues in diphtheria toxin catalytic domain were determined by quantum chemistry calculation and the enzymatic activities of mutant in the active-site were tested in order to provide high effective cytotoxin for target anticancer drugs.

通过量子化学计算确定白喉毒素分子催化区活性中心的关键氨基酸残基，评价其取代后的酶活性的改变，为导向性抗癌药物研究提供高效杀伤细胞工具。

Diphtheria toxin is an exotoxin secreted by Corynebacterium diphtheriae that has been lysogenized by β bacteriophage that carries the DT gene.

白喉毒素是棒状白喉杆菌被β噬菌体感染后分泌的一种外毒素。

The principal purpose of this study is to set up the isolation methods for diphtheria toxin expressed by genes, to purify the toxin with complete biological activities, and to make researches on its toxicities. In the experiments, the target gene was inserted into the cloning vectors--pET22b, then the vectors were introduced into host cells -BL21(DE3). The expression of the toxin was induced by addition of IPTG. The expression products were purified by His-6 label affinity chromatography. Then the diphtheria toxin expressed was transferred to PVC membrane using semidry blotter to determine the amino acid sequence of N-terminal. The "nicked" diphtheria toxin linked by disulfide bond was gained by protease hydrolysis.

为建立重组基因表达白喉毒素的分离纯化方法，制备出具有生物活性的蛋白质毒素，构建了白喉毒素表达载体pET22b-DT，并转入大肠杆菌BL21(DE3)中诱导表达，以融合表达的His-6作为标签通过亲和层析纯化；表达毒素经蛋白酶酶切后，形成了以二硫键连接的与天然结构相同的带"缺口"的白喉毒素，并测定白喉毒素对豚鼠的急性毒性和细胞毒性。

The results indicate that (1) After acclimation and induction, Phosphorus Accumulating Organism not only has the characteristics of denitrification, but also has the characteristics of takeup phosphate in aerobic;(2) Denitrifying phosphate accumulating bacteria using NO3- as electron acceptor indeed existed in the conventional enhanced biological phosphorus removal system;(3) The facultative anaerobe seperated during the process of acclimation are Corynebacterium, Pseudodiphtheria corynebacterium, Staphylococcus and Moraxella; all of which can be functioned as denitrifying phosphorus accumulating to various degree.

试验结果表明：(1)好氧聚磷菌经驯化诱导后不但具有反硝化产氮特性，而且具有好氧聚磷特性；(2)在传统的A2O 工艺中存在有以NO3-为电子受体的反硝化聚磷菌；(3)在驯化过程中分离到的兼性厌氧微生物有棒状杆菌属、假白喉棒杆菌、葡萄球菌属及莫拉氏菌属，且都有不同程度的反硝化聚磷功能。

convalescent carrier：恢复期病原携带者

(2)恢复期病原携带者(convalescent carrier):指临床症状消失后仍能排出病原体的人. 例如白喉、伤寒、乙型病毒性肝炎等. 多数传染病人在恢复期病原携带状态持续时间较短,但少数传染病的病人持续时间较长,个别病例可终身携带. 凡病原携带者持续三个月以内,

Schick test：锡克试验

调查人群对白喉的免疫力可用锡克试验(Schick test)进行测定. 锡克试验的原理是毒素和抗毒素皮内中和试验. 皮内注射毒素后24~48小时无反应时,说明体内有抗毒素,对白喉有免疫力. 阳性反应则相反. 锡克试验除用于检查对白喉有无免疫力外,

td：白喉.破伤风

Toxoid：类毒素

常将不同种类的死疫苗合理混合后制成联合疫苗,如伤寒杆菌和甲型,乙型副伤寒杆菌混合制成的三联疫苗,百白破(百日咳杆菌,白喉类毒素和破伤风类毒素)混合制剂以及多个型别的多价钩端螺旋体疫苗等.2,类毒素(toxoid) 经0.3%-0.4%甲醛处理后失去毒性,

autovaccine：自身疫苗

常用的类毒素有白喉和破伤风类毒素.类毒素也可与死菌苗混合后制成联合疫苗,如百日咳疫苗,白喉类毒素和破伤风类毒素三联疫苗.3,自身疫苗(autovaccine) 是指用从病人自身病灶中分离出来的细菌制成的疫苗.自身疫苗只回注给病人自身,

Corynebacterium diphtheriae：白喉棒状杆菌

药理作用 本品系由白喉棒状杆菌(corynebacterium diphtheriae)产生的外毒素以甲醛溶液解毒后经提纯精制再加氢氧化铝或磷酸铝吸附而成,接种后可刺激机体体液免疫反应,产生抗毒素,可中和白喉杆菌所产生的外毒素,免疫力可持续3~5年,用于预防白喉,
