In addition to the predominant Shigella sonnei, also rarely occurring Shigella serovars have been found in Czechoslovakia: 4 serovars of subgroup A (S. dysenteriae 3, 4, 7 and 12) and 11 serovars of subgroup C (S. boydii 2, 3, 5, 7, 9 lactose-positive, 10, 13,14 aerogenic, mannitol-negative, 15, 16 and the provisional serovar E 16553). First isolations of these serovars were mostly connected with cases imported from abroad. Some serovars were isolated repeatedly.
Newly recognized serovars of S. flexneri (3b, 5a) as well as biochemically aberrant strains of subgroup B (S. flexneri), C (S. boydii) and D (S. sonnei) were isolated. Frequency and importance of some S. flexneri serovars have been changing in the course of time, e.g. S. flexneri 2b, that had evidently been frequent in central Europe 40 years ago, disappeared completely.
Zusätzlich zu der vorherrschenden Shigella sonnei wurden auch selten vorkommende Shigella-Serovare in der Tschechoslowakei gefunden: 4 Serovare der Untergruppe A (S. dysenteriae 3, 4, 7 und 12) und 11 Serovare der Untergruppe C (S. boydii 2, 3, 5, 7, 9 Laktose-positiv, 10, 13, 14 aerogen, Mannit-negativ, 15, 16 und das vorläufige Serovar E 16553). Die Erstisolierungen dieser Serovare standen meist mit aus dem Ausland eingeschleppten Fällen in Zusammenhang. Einige Serovare wurden wiederholt isoliert.
Es wurden neu anerkannte Serovare von S. flexneri (3b, 5a) sowie biochemisch abweichende Stämme der Untergrupppen B (S. flexneri), C (S. boydii) und D (S. sonnei) isoliert.

除了主要的sonnei志贺氏菌外,在捷克斯洛伐克也发现了罕见的志贺氏菌血清型:A亚群4种血清型(痢疾S. 3、4、7和12)和C亚群11种血清型(波地S. 2、3、5、7、9乳糖阳性,10、13、14气源性,甘露醇阴性,15、16和临时血清型E 16553)。首次分离的这些血清型多与境外输入病例有关。部分血清型反复分离。分离出新鉴定的flexneri S.

The location of lipoteichoic acid (LTA) on the surface of group A streptococci was studied by immunoelectron microscopic and ultrastructural cytochemical methods, i. e. by means of LTA antibodies labelled with ferritin, or concanavalin A labelled with ferritin or colloidal gold. All these methods proved the LTA to be located on the outer cell surface of most group A streptococcus strains. The differences in the intensity of labelling paralelled the hydrophobicity of the strains, being substantially higher in the strains exhibiting a high degree of hydrophobicity. Treatment of streptococci with pronase or trypsin led to a complete loss of surface-located LTA. On the other hand, pepsin treatment of streptococci under mild conditions resulted in an increased amount of surface-located LTA in some strains. On the isolated cell walls, LTA could be demonstrated only on the outer surface of the walls. These findings correlated well with the presumed role of group A streptococcus LTA in the adherence of streptococci to the epithelial cells which is accomplished with the aid of surface-located LTA molecules.

Balb/c-mice were intravenously infected with 5 × 104 viable cells of Listeria monocytogenes SLCC 4013. Liver, lung and spleen of the animals showed heavy organ colonization 48 h after infection. Pretreatment of experimental animals with staphylococcal lipoteichoic acid (LTA; 2 mg i.p. 7 and 3 days before challenge) significantly reduced the bacterial count in these organs. In vitro, peritoneal macrophages from LTA-treated mice significantly reduced listerial viability as compared to control cells (p < 0.0025). In vitro, exposure of macrophages from non-treated animals to LTA did not influence their bacterial killing ability.

Certain group L streptococci demonstrate surface receptors for human albumin. Binding of 125I-albumin to group L streptococci could be inhibited by unlabelled albumin preparations from humans, dogs, mice and bovines, but not by albumin from rabbits. The albumin-binding proteins (ABP) could be solubilized from the streptococcal surface by hot acid treatment of the bacteria and isolated by affinity chromatography on human-albumin sepharose. ABP and specific antisera produced against ABP inhibited 125I-albumin binding to group L streptococci. The molecular weight of ABP determined by SDS-PAGE and Western blotting, was approximately 48000 Dalton. ABP preparations of group G streptococci isolated from bovines and humans demonstrated cross reactivity with antiserum produced against group L streptococcal ABP.

Despite its world-wide distribution, the pathogenic serogroup O:5, 27 of Yersinia enterocolitica (Y. e.) has scarcely been considered in the Federal Republic of Germany. In the 1980 to 1986 period, a total of 74 strains from patients was identified at the National Reference Centre for Salmonella, Hamburg. The clinical manifestations of the cases was not different from those associated with Y. e. O:3 and O:9 infections. Six out of 8 patients from whom serum samples were available, developed moderate agglutination titres (1:80-1:1280). Only 8 of the 74 strains were negative in in vitro virulence tests.
A list of biochemical tests is given which permit a differentiation of the pathogenic serogroup O:5, 27 from the apathogenic Y. e. O:5 which is widely distributed in the environment. Serological studies revealed different H antigens in both serogroups. The O antigen factor 27, and a subfactor O:52 which is typical of Y. e. serogroup O:5, are further differential markers; the production of both factor sera is described.
Besides serogroups O:3 and O:9, Y. e. O:5, 27 must be considered as an aetiological agent of human yersiniosis in the Federal Republic of Germany.
尽管小肠结肠炎耶尔森菌(耶尔森菌)在世界范围内分布,但在德意志联邦共和国几乎没有考虑到致病性血清群O: 5,27。在1980年至1986年期间,在汉堡国家沙门氏菌参考中心共鉴定出74株来自患者的菌株。病例的临床表现与耶氏杆菌O:3和O:9感染无明显差异。可获得血清样本的8例患者中有6例出现中度凝集滴度(1:80-1:1280)。74株中仅有8株体外毒力试验阴性。提供了一系列生化试验,可将致病性血清型O: 5.27与广泛分布于环境中的致病性Y. e. O:5区分开来。血清学研究显示两个血清组的H抗原不同。O抗原因子27和y型大肠杆菌血清O:5组典型的O:52亚因子是进一步的鉴别标记;描述了这两种因子血清的产生。在德意志联邦共和国,除o3和o9血清群外,Y. e. o5、27必须被视为人类耶尔森菌病的病原学因子。

Tetracyclines and erythromycin are the chemotherapeutic agents most often used in the Federal Republic of Germany for eradication of U. urealyticum from the male urogenital tract. Few data on current susceptibility in the FRG are available. Therefore, we investigated the minimal inhibitory concentration (MIC) values of 10 chemotherapeutic agents against 27 isolates from the male urethra and 4 ATCC strains of U. urealyticum by a micro broth dilution method using a modified U-9 medium. The MIC90 values (μg/ml) of the chemotherapeutic agents tested were as follows: minocycline-0.25, doxycycline-1.0, tetracycline and chlortetracycline-2.0, erythromycin and streptomycin-4.0, chloramphenicol, gentamicin, rosoxacin-8.0, spectinomycin-32.0. According to the blood levels attained in treatment, the chemotherapeutic agents can be divided into three groups based on the MIC90-values, i.e. sensitive: chloramphenicol, doxycycline, minocycline and streptomycin; weakly effective: Chlortetracycline, tetracycline, spectinomycin and erythromycin; and resistant: gentamicin and rosoxacin.
Tetrazykline und Erythromycin sind die in der Bundesrepublik Deutschland am häufigsten eingesetzten Chemotherapeutika gegen U. urealyticum im männlichen Urogenitaltrakt. Daten zur aktuellen Resistenz-Situation von U. urealyticum gegen Chemotherapeutika stehen kaum zur Verfügung. Deshalb untersuchten wir 27 klinische Isolate und 4 Stämme (ATCC) mittels Mikro-Reihenverdünnungstest gegen 10 Chemotherapeutika, die auch bei sexuell übertragbaren Krankheiten (STD) eingesetzt werden. Die minimale Hemmkonzentration 90 (MHK90) (μg/ml) betrug für: Minocyclin 0,25; Doxycyclin 1,0; Tetracyclin und Chlortetracyclin 2,0; Erythromycin und Streptomycin 4,0; Chloramphenicol, Gentamicin, Rosoxazin 8,0; Spectinomycin 32,0. Aufgrund der therapeutisch erreichbaren Serumspiegel und der ermittelten MHK90-Werte können die getesteten Chemotherapeutica in die Gruppen: sensibel: Chloramphenicol, Doxycyclin, Minocyclin und Streptomycin, schwach empfindlich: Chlortetrazyklin, Tetrazyklin, Spectinomycin und Erythromycin und resistent: Gentamicin und Rosoxazin eingeteilt werden.
四环素和红霉素是在德意志联邦共和国根除男性泌尿生殖道解脲菌最常用的化疗药物。关于FRG中电流敏感性的数据很少。因此,我们采用改良U-9培养基,采用微肉汤稀释法研究了10种化疗药物对27株男性尿道分离株和4株解脲酵母菌ATCC株的最小抑菌浓度(MIC)值。所测化疗药物MIC90值(μg/ml)分别为:二甲胺四环素-0.25、强力霉素-1.0、四环素和氯霉素-2.0、红霉素和链霉素-4.0、氯霉素、庆大霉素、红沙霉素-8.0、大霉素-32.0。根据治疗时达到的血药浓度,根据mic90值将化疗药物分为三组,即敏感组:氯霉素、多西环素、米诺环素和链霉素;弱效:四环素、四环素、大观霉素、红霉素;还有耐药的:庆大霉素和红沙星。四合酶和红霉素可能在德国联邦共和国死亡häufigsten eingesetzten化疗药物在männlichen Urogenitaltrakt。[3] [j] .耐药资料-解脲酵母菌化学疗法的研究进展[j]。Deshalb untersutenir 27 klinische Isolate and 4 Stämme (ATCC) mittelels micro - reihenverddnnungstest gegen 10 Chemotherapeutika, die of the sexuell bertragbaren Krankheiten (STD) eingesetzt werden。最小hemmkonconcentration 90 (MHK90) (μg/ml):盐酸米诺环素0,25;Doxycyclin 1,0;四环素和氯四环素2,0;红霉素和链霉素4;氯霉素、庆大霉素、红沙星8,0;32岁的壮观霉素0。化疗组:敏感组:氯霉素、多西环素、米诺环素和链霉素;耐药组:氯四合胞素、四合胞素、大观霉素和红霉素;耐药组:庆大霉素和红霉素;

Of the 96 E. coli strains belonging to 9 enteroinvasive serovars 79 (82.3%) turned out to be sensitive to colicin Js but none of the 115 strains of E. coli isolates from the feces of healthy persons without diarrhoea exhibited this type of sensitivity reaction. Of the colicin Js-sensitive strains, 89.9% (71 out of 79) gave also positive reactions in the Serény test for enteroinvasiveness. The remaining strains belonging to enterointervasive E. coli serovars but showing no sensitivity to colicin Js were as a rule negative in the Serény test.

The degree of binding was determined between DNA preparations from 65 staphylococci representing clusters defined in a numerical phenetic survey and 3H-labelled DNA from reference strains of S. epidermidis, S. haemolyticus, S. hominis, S. saprophyticus and S. warneri. The congruence between the DNA pairing and numerical phenetic data was good with S. epidermidis and S. saprophyticus being shown to be genomic species. However, some strains identified as S. epidermidis using recommended diagnostic procedures were found to belong to other taxa, notably S. simulans and S. warneri. The moles percent guanine plus cytosine content of the DNA of the test strains was within the range 27 to 34.
DNA-Hybridisierungstests an insgesamt 65 Stämmen von koagulasenegativen Staphylokokken wurden mit 3H-markierter Referenz-DNA von Typstämmen der Spezies Staphylococcus epidermidis, S. haemolyticus, S. hominis, S. saprophyticus und S. warneri durchgeführt. Zwischen den Daten der numerischen Taxonomie und den jetzigen DNA-Hybridisierungstests konnte bei den Stämmen der Spezies S. epidermidis und S. saprophyticus eine gute Übereinstimmung konstatiert werden. Einige Stämme waren allerdings falsch klassifiziert worden, sie gehören zu anderen Spezies wie S. simulans und S. warneri. Die Guanin-und Cytosin-Werte der überprüften Staphylokokken lagen zwischen 27 und 34 mol%.

Wild rabbits — Oryctolagus cuniculi — living in large numbers in a protected zone of Tuscany, the park of Migliarino — San Rossore — Massaciuccoli, showed to be carriers of the hard tick Rhipicephalus pusillus, previously observed in North Africa and Sicily.
Antibodies to Rickettsia conorii and R. slovaca were detected in 78.9 per cent of the wild rabbits captured in that area. Seroconversion towards R. conorii was also observed in guinea pigs inoculated with homogenates of R. pusillus parasitizing the wild rabbits. These results identify an ecological niche of rickettsiae of the Spotted fever group in the host-parasite system O. cuniculi/R. pusillus.
Attempts to isolate rickettsiae from the ticks and the wild rabbits were unsuccessful both in the egg yolk sac and in the guinea pig. This failure probably shows the low pathogenicity of the ricketsiae parasitizing the biosystem O. cuniculi/R. pusillus.

Bei 78,9% der in diesem Gebiet gefangenen Wildkaninchen wurden Antikörper gegen Rickettsia conorii und R. slovaca festgestellt. Eine R. coworii-Serokonversion wurde auch bei Meerschweinchen beobachtet, die mit Homogenaten des Wildkaninchen-Parasiten R. pusillus beimpft worden waren. Diese Ergebnisse lassen eine ökologische Nische für die Rickettsien der Spotted-Fever-Gruppe in dem Wirt-Parasiten-System O. cuniculo — R. pusillus erkennen. Bemühungen um eine Isolierung der Rickettsien aus den Zecken und den Wildkaninchen im Eidottersack und die Meerschweinchen blieben erfolglos.
