In vitro expression of a 22-kilodalton Yersinia pestis polypeptide immunologically related to the 25-kilodalton plasmid-encoded protein of the three pathogenic Yersinia species.

Author(s) : Chalvignac, M A , Carniel, E , Tram, C , Joseph-Francois, A , Mollaret, H H
Description : Antibodies raised against the 25-kilodalton (p25) plasmid-encoded polypeptide of Yersinia enterocolitica recognized the homologous protein in the three Yersinia species grown in vitro. This polypeptide was recovered from whole cells as well as from the fluid supernatant of bacteria grown at 37 degre...

Temperature-modulated immunogenicity to Yersinia pestis from Yersinia enterocolitica O3.

Author(s) : Alonso, J M , Hurtrel, B , Mazigh, D , Chalvignac, M A , Mollaret, H H
Description : The ability of Yersinia enterocolitica O3, grown at 25 degrees C, to promote cross-immunity to Y. pestis was lost after repeated subcultures at 37 degrees C, which selected for bacterial populations having lower in vivo survival. Subculturing Y. enterocolitica O3 from 37 to 25 degrees C restored the...

Nucleotide sequence of the thrA gene of Escherichia coli.

Author(s) : Katinka, M , Cossart, P , Sibilli, L , Saint-Girons, I , Chalvignac, M A , Le Bras, G , Cohen, G N , Yaniv, M
Description : The thrA gene of Escherichia coli codes for a single polypeptide chain having two enzymatic activities required for the biosynthesis of threonine, aspartokinase I and homoserine dehydrogenase I. This gene was cloned in a bacterial plasmid and its complete nucleotide sequence was established. It cont...
