[Genetic polymorphism of erythrocytic enzymes in the Rennes area. Frequency of adenylate kinase, esterase D, adenosine deaminase, 6-phosphogluconate dehydrogenase, glutamate-pyruvate transaminase and glyoxyalase I phenotypes].

Blood donors from the Centre Régional de Transfusion Sanguine de Rennes were investigated for the phenotypic distribution of seven enzymatic systems : adenylate kinase, adenosine deaminase, esterase D, 6-phosphogluconate dehydrogenase, glutamate-pyruvate transaminase, phosphoglucomutase, and glyoxalase I. Two unusual phenotypes were observed: phenotype 6-1 for adenosine deaminase and phenotype 3-1 for transaminase GPT. For five of these enzymes, the statistical analysis points out significant differences in one or several of the European populations described in the literature.

[Genetic polymorphism of poultry blood serum esterases in relation to resistance to bacterial infections].

The experiments were carried out on White Leghorn, White Rock and Cornish chickens during the 1974--1975 season. The aim of the investigation was to study polymorphism of blood esterases in chickens in relation to their resistance to Salmonella pullorum and S. gallinarum. The data obtained indicate the following: 1) an additional, inheritant alyesterase fraction (A1) Appears in blood serum of resistant chickens after their contamination with Salmonella; 2) most chickens, which are resistant to Salmonella, have heterozygous genotype for blood serum cholinesterase.
