Out of the total of 401 strains, 363 (90.5%) were typable. Among human strains, 32 serotypes were identified, more frequently encountered being (in a decreasing order) 29, 4, 21, 2, 1, 9, 59, 44, 36, 48, 28, 8, 47, 5, 11, 57, 10, 32, 55 which sum up 89.5% of the 296 typable strains. Within C. jejuni species, serogroup 4 was the predominant one and for the C. coli one--29. Animal strains were distributed into 16 serogroups out of which 29, 26, 48, 55, 44 were more frequently encountered. The serogroups identified among animal strains were encountered, with a single exception, among human strains, too, but with a different frequency. The importance of serogrouping as an epidemiological marker, was confirmed by serogroup identity of the strains within some family foci, by the oneness, as serogroups, in the case of repeated isolations from the same patient as well as by establishing an epidemiological diagnosis, in the case of an epidemic, occurring among the members of a given community.","PeriodicalId":75543,"journal":{"name":"Archives roumaines de pathologie experimentales et de microbiologie","volume":"49 1","pages":"79-88"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13256260","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}

Examination of fine sections from samples incubated between 30 and 120 minutes at 37 degrees C, emphasized phagocytic ability of activated macrophages (29-69% activated macrophages phagocytized 3.7-5.6 bacteria/cell, in contrast to 23-43% with 2.6-4.4 bacteria/phagocytized by non-immune cells). The ultrastructural studies of activated macrophages, performed by electron microscopy, showed the following aspects: a) macrophages with pseudopodiform prolongations, presenting the tendency of bacterial sequestration: b) phagosomes with ingested virulent germs; c). bacteria presenting various degrees of wall and cytoplasm alterations; d). mitochondria with multiple cristae; e). cells with well developed Golgi apparatus and the presence of lysosomes in great numbers; f). existence of a space between the phagosome membrane and the bacterial wall.

Twelve Cryptosporidium positive cases were identified, meaning a general prevalence of 2.48% Cryptosporidium infection was detected in all investigated epidemiological groups: children, animal handlers, immunodeficient patients, immunocompetent adults with acute gastroenteritis. The risk factors hierarchy elicited the role of children collectivities attending, for acquiring the parasite in infantile cryptosporidiosis, while the opportunistic and zoonotic feature of the disease was especially present in adults' cryptosporidiosis. The assessment of cryptosporidiosis evolution, according to patients' immune status, has not allowed an obvious clinical discrepancy, since the immunocompetent subjects with professional risk had presented a prolonged oocysts excretion. The different clinico-epidemiological and parasitological features of Cryptosporidium infection are commented and the importance of applying Cryptosporidium methodology in current diagnosis practice is emphasized.","PeriodicalId":75543,"journal":{"name":"Archives roumaines de pathologie experimentales et de microbiologie","volume":"48 4","pages":"357-65"},"PeriodicalIF":0.0,"publicationDate":"1989-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13631312","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}
