The fractions explored included phospholipids, Cord factor, ethanol-extractable lipids, waxes A, B, C + D and fats. The fractions were divided into three groups according to their effectiveness. 1. The Cord factor and phospholipids from all the studied strains were effective in the antituberculosis and antitumour models with the only exception of strain 725 phospholipids. Phospholipids from all strains were capable of inducing tuberculin allergy. 2. In the second group (waxes A, C + D and lipids extractable by ethanol) a variance was observed in the antigenic properties of identical fractions from different strains suggesting differing metabolism in the strains producing these fractions. A mixture of waxes C + D from the French and Danish strains showed a degree of suppression in its antituberculosis effectiveness. 3. Waxes B and fats were entirely ineffective in the antitumour model and, with the exception of waxes B from strain 725 and fats from the Japanese strain, in the antituberculosis model. The antituberculosis and antitumour effectiveness directly depended on the content of a mycolic acid complex in fractions. Tuberculin allergenicity was associated with the intensity of phospholipid production by mycobacteria.</p>","PeriodicalId":76007,"journal":{"name":"Journal of hygiene, epidemiology, microbiology, and immunology","volume":"35 1","pages":"73-82"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12879192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The family members were identified through the patients and interviewed after completing a questionnaire, their diseases were medically confirmed by local general practitioners. In two families consanguineous marriages were identified with the coefficients of inbreeding of 0.03125 and 0.01563, respectively: one patient, a dizygotic twin of an unaffected sister, was a granddaughter of first cousins, the second patient was the third daughter of second cousins. These cases of CVID strongly support the autosomal recessivity of the underlying genes. One male patient with CVID was shown to be related to a patient with X-linked hypogammaglobulinaemia, both sharing a common carrier. The different clinical courses of their diseases suggest two genetically determined immunodeficiencies and genetic heterogeneity. No family had an unusual clustering of cancer. The occurrence of tumours in the blood relatives of CVID patients was not significantly higher than in the relatives of spouse controls. Immunological examination of 30 first degree relatives of the CVID patients revealed three children (2 males and 1 female) with selective IgA deficiency, in one boy combined with elevated serum IgE level.

A commonly accepted method developed in 1985 using our own experience was used for strain isolation and culturing. A variety of nutrient media in combination with different supplementary substances (antibiotics, growth factors) and additives, such as horse serum, were verified as well as filtration and Fortner's procedures. The best results were obtained when material was stored in thioglycolate transport medium accompanied by cold enrichment (24 h at 4 degrees C) and repeated inoculation into appropriate solid nutrient medium. Owing to the simple culturing of C. jejuni, the number of not elucidated diarrheas was reduced and the incidence of campylobacteriosis (approximately 12 %) is higher than that of salmonellosis and shigellosis. A total of 245 C. jejuni strains was classified using Kahlich's antigenic scheme. The incidence of serovars 1 and 2 was greater than 10 %. Five serovars (13, 17, 25, 26 and 27) were represented by only one strain. The study of campylobacteriosis also revealed the long-term excretion of C. jejuni by convalescents (71 days at most) as well as the occurrence of family outbreaks.
