Antigenic analysis of vibrio cholerae O1 by crossed immunoelectrophoresis 霍乱弧菌O1抗原的交叉免疫电泳分析
Shahjahan Kabir

Antigens from Vibrio cholerae O1 were analyzed by crossed immunoelectophoresis (CIE) using sera from immunized rabbits. Thirty different anode-migrating antigens were detected in sonicated antigen preparations of V. cholerae. These antigens were numbered in order to establish a reference precipitation pattern. Antigen no. 30 was identified as the lipopolysaccharide (LPS) antigen, because it reacted with (i) periodic acid-Schiff (PAS) reagent and (ii) the affinity-purified anti-LPS antibodies. Treatment with proteinase K demonstrated that most of the precipitation lines were due to proteins, a part of which were localised at the cell surface. The major outer membrane protein was found to be closely associated with the precipitation line due to the LPS (antigen no. 30). The antigenicity and immunogenicity of V. cholerae cells killed by different methods (merthiolate, heat, phenol, formalin) were examined. As determined by CIE, killing with merthiolate preserved most of the major components of V. cholerae. Heat, phenol and formalin altered the antigenic mosaic of V. cholerae. These results suggested that CIE can be used to analyze several aspects of V. cholerae antigens.

Antigene von Vibrio cholerae O1 wurden unter Verwendung von Kaninchenimmunseren mit der gekreuzten Immunelektophorese (CIE) untersucht. In ultraschallbehandelten Antigenpräparationen wurden 30 verschiedene Antigene ermittelt. Ein Antigen wurde als Lipopolysaccharidantigen identifiziert. Die meisten anderen Präzipitationslinien entsprechen Proteinantigenen, von denen ein Teil an der Oberfläche lokalisiert ist. Die Antigenität, Immunogenität und die Hämagglutinationsaktivität von Vibrio cholerae-Zellen, die mit verschiedenen Methoden (Hitze, Merthiolat, Phenol, Formalin) abgetötet worden waren, wurde vergleichend untersucht. Mit der CIE und der isoelektrischen Fokussierung wurde festgestellt, daß die Abtötung mit Merthiolat die Hauptkomponenten von V. cholerae am besten bewahrt. Hitze, Phenol und Formalin alterieren sowohl das Antigen-mosaik wie auch die Hämagglutinationsaktivität von V. cholerae.

Diese Ergebnisse zeigen, daß die CIE für die Analyse von Choleraantigen geeignet ist.

In 1986, 1711 nymphal and adult Ixodes ricinus originating from Berlin (West) forests were examined individually or in pools of up to 10 ticks for the presence of Borrelia burgdorferi, the etiologic agent of Lyme borreliosis. Detection of borreliae was carried out by means of a culture method using modified Barbour-Stoenner-Kelly-Medium (BSK II).

Tick populations from 14 out of 15 locations contained positive specimens. The calculated minimal infection rate of pooled ticks was 2.5% in nymphs (n = 1365), 10.2% in females (n = 59), and 5.3% in males (n = 114). Among those ticks examined individually, none of the nymphs (n = 49) proved to be positive but B. burgdorferi was isolated from 8.2% of the females (n = 73) and 7.8% of the males (n = 51). Fifty-five out of 56 isolates were identified as B. burgdorferi by means of an indirect immunofluorescence test (IFT) using monoclonal antibody H 5332.

From these results B. burgdorferi must be considered as being present in the Berlin area.

Im Jahre 1986 wurden 1711 Ixodes ricinus (Nymphen und Adulte) aus Berlin (West) einzeln oder in Gruppen von maximal 10 Zecken auf Borrelia burgdorferi, dem Erreger der Lyme-Borreliose, untersucht. Der Borreliennachweis erfolgte kulturell in modifiziertem Barbour-Stoenner-Kelly-Medium (BSK II).

In 14 von 15 aufgesuchten Forstlokalitäten wurden positive Zecken gefunden. Die minimale Durchseuchungsrate der in Gruppen untersuchten Zecken betrug bei Nymphen 2,5% (n = 1365), bei Weibchen 10,2% (n = 59) und bei Männchen 5,3% (n = 114). Von einzeln untersuchten Zecken waren alle Nymphen (n = 49) negativ, jedoch wurde aus 8,2% der Weibchen (n = 73) und aus 7,8% der Männchen (n = 51) B. burgdorferi isoliert. Fünfundzwanzig von insgesamt 56 Isolaten wurden mit einem indirekten Immunofluoreszenztest (IFT) unter Verwendung von monoklonalen Antikörpern H 5332 als B. burgdorferi identifiziert.

Auf Grund dieser Ergebnisse muß damit gerechnet werden, daß B. burgdorferi im gesamten Berliner Raum in I. ricinus vorkommt.

Ability of smooth and rough variants of mycobacterium avium and M. intracellulare to multiply and survive intracellularly: role of C-mycosides 光滑型和粗糙型鸟分枝杆菌和胞内分枝杆菌在细胞内繁殖和存活的能力:c -真菌苷的作用

A spontaneous rough (Rg) mutant of M. avium ATCC 15769 was mutagenized using N-methyl-N-nitro-nitrosoguanidine (MNNG). Out of 54 clones initially chosen on the basis of their morphological appearance on the 7H11 agar, seven Rg clones were selected on the basis of their response to current biochemical tests, and were later characterized for their cell wall amphiphilic contents (analysis of loosely-bound surface lipids for mycosides, peptidolipids, phospholipids, and mycolic acids by thin layer chromatography, and fatty acids by gas chromatography), and ability to grow intracellularly inside J-774 macrophages. A parallel study was also performed on a previously reported Rg mutant of M. intracellulare serovar 20 (W. W. Barrow and P. J. Brennan, J. Bact. 150 (1982) 381–384) which lacked the ability to synthesize mycosides C (MYC). The results obtained were compared to parental smooth (Sm) colony-types of the respective M. avium-intracellulare strains. Our results showed that neither the ninhydrin-reacting lipids (probably peptidolipids) nor the glycopeptidolipids (mycosides C) were primary factors responsible for the intracellular survival and multiplication of these bacteria. Ultrastructural studies showed that although the polysaccharide-rich outer wall layer (POL) in case of MYC Rg strain was not uniformly distributed and contained blebs, these bacteria formed the characteristic electron-transparent zone (ETZ) upon phagocytosis by macrophages. Furthermore, the multiplication of MYC Rg strain inside macrophages did not result in intracellular selection of MYC+ bacteria, nor in Rg to Sm transition.

用n -甲基-n -硝基-亚硝基胍(MNNG)诱变了一株禽分枝杆菌ATCC 15769的粗突变体(Rg)。在最初根据其在7H11琼脂上的形态外观选择的54个克隆中,根据其对当前生化测试的反应选择了7个Rg克隆,并随后对其细胞壁两亲性含量进行了表征(通过薄层色谱分析松散结合的表面脂质,包括霉菌苷、肽脂、磷脂和霉菌酸,通过气相色谱分析脂肪酸),并在J-774巨噬细胞内生长的能力。对先前报道的胞内分枝杆菌血清型20的Rg突变体(W. W. Barrow and P. J. Brennan, J. bat . 150(1982) 381-384)也进行了平行研究,该突变体缺乏合成真菌苷C (MYC−)的能力。所获得的结果与亲本光滑(Sm)菌落型进行了比较。我们的研究结果表明,与茚三酮反应的脂质(可能是肽脂)和糖肽类脂质(真菌苷C)都不是这些细菌在细胞内存活和繁殖的主要因素。超微结构研究表明,尽管MYC−Rg菌株富含多糖的外壁层(POL)分布不均匀且含有气泡,但这些细菌在被巨噬细胞吞噬后形成了特有的电子透明区(ETZ)。此外,巨噬细胞内MYC−Rg菌株的增殖不会导致MYC+菌的胞内选择,也不会导致Rg向Sm的转变。

Occurrence and significance of clostridium difficile in faecal specimens of hospitalized children 住院儿童粪便标本中艰难梭菌的发生及意义
Wolfgang Karsch , Elke Strelau, Wolf-Dieter Grahlow, Evelin Fischer, Rotraud Schulz

Stool specimens from 766 hospitalized children, 418 with diarrhoea and 348 controls, were investigated for C. difficile. In both groups the rate of isolation was highest (about 30%) during the first year of life, dropping to nearly 5% in older children. There was no significant difference in the frequency of C. difficile in children with diarrhoea and the controls nor was there a significant influence of previous antibiotic therapy on the rate of isolation. 111/135 strains (82.2%) produced toxin B and 58/135 strains (43%) produced toxin A measured by Y-1- cell culture (toxin B) and rabbit ileal loop test (toxin A). We did not find any significant difference in the toxin production between strains isolated from diarrhoeal children and from the controls. A total of 285 stool specimens was investigated for toxin B production in vivo. There was no significant difference of toxin B in the stool specimens of both groups.

Stuhlproben von 766 hospitalisierten Kindern, 418 mit Enteritis und 348 Kontrollen, wurden auf C. difficile untersucht. In beiden Gruppen war die Isolierungrate mit ca. 30% am höchsten im ersten Lebensjahr und fiel auf ca. 5% bei älteren Kindern. Die Isolierungshäufigkeit zeigte in beiden Gruppen keinen signifikanten Unterschied. In beiden Gruppen wurde kein signifikanter Einfluß einer vorherigen antibiotischen Therapie auf die Isolierungsrate von C. difficile festgestellt. 111/135 Stämmen (82,2%) bildeten Toxin B und 58/135 Stämmen (43%) bildeten Toxin A. Es wurde kein signifikanter Unterschied in der Häufigkeit der Toxinbildung zwischen Stämmen von Kindern mit Enteritis und Stämmen aus der Kontrollgruppe gefunden. In 285 Stuhlproben wurde Toxin B in vivo bestimmt. Es bestand auch hier kein signifikanter Unterschied in der Häufigkeit der Bildung von Toxin B zwischen beiden Gruppen.

Rapid detection of group B streptococci in vaginal swabs of parturients by Latex Particle Agglutination 乳胶颗粒凝集法快速检测产妇阴道拭子中B族链球菌
Jörg E. Hoppe , Christiane Lindenau, Wolfram Höfler

Duplicate high vaginal swabs were obtained from 200 parturient women at Abeokuta (Nigeria). By culture on a selective agar twenty-two women (11%) were found to harbour group B streptococci. The second swab was subjected to a 45 min enzymatic extraction procedure and then tested in a latex agglutination test for group B streptococcal antigen (Wellcogen Strep B; Wellcome Diagnostics, Dartford, UK). The latex test permitted the detection of three out of 22 colonized women (overall sensitivity 13.6%). The sensitivity for detection of heavy colonization was 50% (three out of six women). It is concluded that the sensitivity of the method employed for rapid detection of group B streptococcal antigen in vaginal swabs is still unsatisfactory.

Doppelte hohe Vaginalabstriche wurden entnommen bei 200 vor der Geburt stehenden Frauen in Abeokuta (Nigeria).

Antibodies against toxic shock syndrome toxin No. 1 (TSST-1) in Poland 波兰抗中毒性休克综合征毒素1号(TSST-1)抗体
Małgorzata Bulanda , Gerhard Kunstmann , Gottfried Mauff , Marian Kurek , Gerhard Pulverer , Piotr B. Heczko

A total of 174 sera from healthy Polish individuals of different age groups were tested for TSST-1 antibody by the micro-ELISA method. Over 90% of sera contained the antibody with titres equal to above 1:102, even in children and adolescents. The data suggest that the majority of the Polish population acquires TSST-1-antibody during early childhood, whereas a small portion of the population seems to remain anti-TSST-1-negative.

Eine Stichprobe von 174 Seren aus der polnischen Bevölkerung wurde im Mikro-ELISA auf das Vorhandensein von TSST-1 Antikörpern untersucht. Bei über 90% der Probanden einchließlich von Kindern und Jugendlichen fand sich ein Antikörpertiter von mindestens 1:102. Die Befunde berechtigen zu der Annahme, daß die überwiegende Mehrheit der Probanden TSST-1-Antikörper bereits in der frühen Kindheit erwirbt, während ein kleiner Anteil der Bevölkerung auch langfristig keine antitoxische Immunität zu erwerben scheint.

Enhancement of neutrophil adherence to toxocara canis larvae by the C3 component of complement and IgG antibodies 补体C3成分和IgG抗体增强犬弓形虫幼虫对中性粒细胞的粘附
Martin Huwer , Sabine Sanft, Jabbar S. Ahmed

In the present study, the binding of human neutrophils to Toxocara canis larvae was examined in vitro. It was found that IgG and/or the C3 component of complement were able to enhance the attachment of the cells to the parasites. This was associated with the generation of strong chemiluminescence reactions.

Despite the binding of the cells, the larvae were able to escape and to maintain their infectivity. This was apparent, since the parasites could survive and migrate into different organs including the brain after having been inoculated into mice.

In-vitro-Untersuchungen zur Interaktion neutrophiler Granulozyten vom Menschen mit infektiösen Larven von Toxocara canis wurden durchgeführt. Die Ergebnisse von Zellanlagerungs- und Immunfluoreszenztests zeigen, daß sowohl IgG, als auch die C3-Komponente des Komplementsystems an der Zellaggregation am Parasiten beteiligt sind. Im Chemilumineszenztest war als Ausdruck der Aktivierung der phagozytischen Zellen eine ausgeprägte Reaktion zu beobachten. Trotz der starken Zellanlagerung überlebten die Larven und behielten ihre Infektiosität. Nach Inokulation in Mäuse wurden die Larven im Gehirn, sowie in verschiedenen anderen Organen gefunden.

Complex Typing of Methicillin-resistant Staphylococcus aureus (MRSA) 耐甲氧西林金黄色葡萄球菌(MRSA)复合分型
Wolfgang Witte , Richard R. Marples , Judith F. Richardson

To discriminate between methicillin-resistant Staphylococcus aureus from 5 nosocomial outbreaks and from sporadic nosocomial infections, the efficacy of a complex typing scheme by phage typing, biochemical typing, resistance phenotype, plasmid profiles, plasmid patterns and attribution of resistance determinants to the chromosome was studied. In addition to the International Basic Set and experimental phages 88–93,10 experimental phages from the Public Health Laboratory Service, Colindale, London, were used for phage-typing. The 10 experimental phages from PHLS in particular, in combination with plasmid profiles and plasmid patterns, were of special discriminative value.

A New Chromogenic Assay for Direct Detection of Staphylocoagulase 一种新的直接检测葡萄凝固酶的显色法
Małgorzata Bulanda , Zenon Weęgrzynowicz , Marek Ciurak , Janusz Kowalczyk , Gotfryd Kupryszewski , Maria Gruszka , Piotr B. Heczko , Gerhard Pulverer

Tube test for detection of staphylococcal coagulase, despite of many disadvantages, is commonly used in clinical microbiology for identification of Staphylococcus aureus. In this paper a new chromogenic method for detection of the coagulase directly in staphylococcal cultures is described and evaluated on the basis of a comparison with the standard tube assay. The chromogenic assay appeared to be as sensitive as the tube test but results of the former one can be read in a few hours without any apparatus.

Trotz mancher Nachteile wird der Röhrchentest generell zum Nachweis der Staphylokokken-Koagulase in der medizinischen Mikrobiologie verwendet, um die Spezies Staphylococcus aureus zu identifizieren. In vorliegender Arbeit wird eine neue chromogene Methode zum Nachweis der Koagulase direkt in der Staphylokokken-Kultur vorgestellt und mit dem Standard-Röhrchentest verglichen. Der chromogene Nachweistest erwies sich dem Standard-Röhrchentest als ebenbürtig, kann aber in wenigen Stunden ohne apparative Hilfe abgelesen werden.

Electron-microscopic observation of adherence of serotype c Streptococcus mutans to the enamel surface due to glucan synthesis 血清c型变形链球菌因葡聚糖合成而粘附在牙釉质表面的电镜观察
Toshihiko Koga , Yoshihisa Toda , Itaru Moro , Shigeyuki Hamada

Cellular adherence of three strains with water-insoluble glucan (IG)-synthesizing ability and a strain lacking the ability of serotype c Streptococcus mutans to the saliva-coated human enamel surface was examined by scanning (SEM) and transmission (TEM) electron-microscopy. SEM revealed that organisms of all strains used adhered directly to the enamel surface in the absence of sucrose. Cell-to-cell attachment was scarcely observed in the absence of sucrose. Cell-to-cell attachmment via amorphous substance on the cell surface was observed by SEM when the strains with IG-synthesizing ability were incubated with the saliva-coated enamel in the presence of sucrose. TEM revealed that cell-associated enzymes of these strains synthesized filamentous and double-stranded fibrillar structures from sucrose. The strain lacking IG-synthesizing ability was unable to induce cell-to-cell attachment in the presence of sucrose, nor was it able to synthesize the amorphous substance. These results indicate that production of IG by cell-associated glucosyltransferase participates in cellular accumulation of serotype c S. mutans.

用扫描电镜(SEM)和透射电镜(TEM)观察了具有不溶性葡聚糖(IG)合成能力的3株和缺乏血清型变形链球菌(c型)对唾液包被人牙釉质表面的细胞粘附性。扫描电镜显示,在没有蔗糖的情况下,所有菌株的微生物都直接粘附在牙釉质表面。在没有蔗糖的情况下,几乎观察不到细胞间的附着。将具有igg合成能力的菌株与唾液包覆的牙釉质在蔗糖的作用下孵育时,通过扫描电镜观察到细胞间通过细胞表面无定形物质的附着。透射电镜显示,这些菌株的细胞相关酶从蔗糖合成丝状和双链纤维结构。缺乏ig合成能力的菌株在蔗糖存在的情况下不能诱导细胞间的附着,也不能合成无定形物质。这些结果表明,通过细胞相关葡萄糖基转移酶产生的IG参与了血清型c突变体的细胞积累。
