Mucosal and systemic humoral immune response of turkeys after infection and reinfection with a Chlamydia psittaci serovar D strain4194
and the birds, which received only a single infection. Anti-chlamydial antibodies in sera, tears, and tracheal washings were determined by IgA and IgG immunoblot assays. A clear local and systemic ...
Cervical cancer screening in the Flemish region (Belgium): measurement of the attendance rate by telephone interview.
Associations between screening status and a set of explanatory variables (demographic, socioeconomic determinants and exposition to primary risk factors for cervical cancer) were studied by logistic regression ...
Pathotypes of bovine verotoxigenic Escherichia coli isolates producing attaching/effacing (AE) lesions in the ligated intestinal loop assay in rabbits51
nor the hfp loci which are involved in early attachment stage, and that not all of them possess an eaeB gene, as determined by the colony hybridization assay. Have these bovine VTEC isolates lost some ...
Quantitative image analysis as an alternative to chemical analysis for follow-up of liver biopsies from a toucan with hemochromatosis. A technique with potential value for the follow-up of hemochromatosis in humans.
sections versus chemical analysis for determination of the iron content of serial liver biopsies taken at regular intervals after the onset of treatment, in a case of hemochromatosis in a channel-billed ...
In vivo interleukin-4 regulation of antibody responses in euthymic and athymic mice to a T-independent antigen (hydroxyethyl starch).
and especially in those athymic mice remains to be determined. Health Topics: Immunity Service: Réponse immunitaire Immuunrespons Immune response Manuscript versions: DOI: ...
Multicentric epidemiological study of Aspergillus fumigatus isolates by multilocus enzyme electrophoresis36666
obtained from three hospitals in different geographical areas and of eight culture collection strains were determined by multilocus enzyme electrophoresis. Twelve of the 17 enzymatic loci studied were ...
Diversity of DNA fingerprints in Cryptococcus neoformans36661
a nearby pigeon coop. DNA fingerprint stability was determined for 53 isolates from nine non- AIDS patients at different time intervals during 5 to 128 weeks of antifungal therapy. For eight patients, the ...
Individual chaperones required for Yop secretion by Yersinia.
encode a YopD-specific chaperone, which we called SycD. Determination of the dependence of YopB on SycD requires further investigation. SycE, SycH, and SycD appear to be members of a new family of ...
Identification of DNA sequences recognized by VirF, the transcriptional activator of the Yersinia yop regulon.
vitro and that specifically binds to the promoter region of VirF-regulated genes. In this work, we determined the sequences of eight VirF-binding sites from four different genes, by DN ase I or hydroxyl ...
Typing of Clostridium perfringens by in vitro amplification of toxin genes54
Veterinary Medicine work Abstract: The strains of Clostridium perfringens are classified according to major toxins produced. Classically, this determination involves the seroneutralization of their lethal ...
