Fermentation of glucose-1-phosphate: a screening test for fermentative Bacteroides species

Fermentation of sugars and fermentative enzymes

Detection of glucose-phosphate isomerase deficiency by a screening procedure.

G LUCOSE-PHOSPHATE ISOMERASE (GPI) controls the equilibrium between glucose-6-phosphate (G-6-P) and fructose-6-phosphate (F-6-P). Though G?I does not seem to have a rate-limiting function in red cell glycolysis,’ deficiencies of this enzyme cause hereditary nonspherocytic hemolytic anemia.2 Twelve cases from nine different families have been reported suffering from hemolytic anemia caused by G?...

Neonatal screening for glucose-6-phosphate dehydrogenase deficiency: sex distribution.

Eight hundred and six newborn infants at high risk for glucose-6-phosphate dehydrogenase (G-6-PD) deficiency were screened; 30.2% of the boys and 10.4% of the girls had severe G-6-PD deficiency. Surprisingly, 14% of the enzyme deficient girls had a father from a low risk ethnic group. Girls of high risk mothers should be screened for G-6-PD deficiency regardless of paternal origin.

Evaluation of xylan fermentation for the identification of Bacteroides ovatus and Bacteroides thetaiotaomicron.

The reliability of xylan fermentation in distinguishing Bacteroides ovatus from Bacteroides thetaiotaomicron was examined with strains previously identified by DNA homology studies or bacteriophage sensitivity testing or both. All of the 12 B. ovatus strains produced acid ranging from pH 5.0 to 5.6 in peptone-yeast-xylan broth; none of the 19 B. thetaiotaomicron strains produced acid, and the f...

The glucose challenge test for screening of gestational diabetes.

BACKGROUND The frequency of gestational diabetes mellitus (GDM) is 0.6% -15% of pregnant woman. The modern trend towards the delay starting family is the main factor responsible for increase prevalence of GDM. This condition is associated with the adverse effect on mother and fetus, so it is important to find out the GDM by screening of all the pregnant women. OBJECTIVE To observe the feasibi...
