brain abscess/carbohydrate

Citrobacter species are opportunistic bacterial pathogens that are implicated in both nosocomial and community-acquired infections. Among the Citrobacter species, Citrobacter koseri is often isolated from clinical material, and it can cause meningitis and brain abscesses in neonates and

Streptococcus intermedius strain UNS 35, a brain abscess isolate, produced extracellular hyaluronidase when grown in brain heart infusion broth. Chemical assays with this enzyme indicated that hyaluronate depolymerisation resulted in the formation of carbohydrate moieties with N-acetylglucosamine at

The present studies were performed to elucidate the factors responsible for the relative resistance of the brain to bacterial infections. As a model, group A streptococci were used to produce an experimental brain infection in mice. Attention was focussed on the activity of brain macrophages, the

The ketogenic diet is an evidence-based treatment for resistant epilepsy including Lennox-Gastaut syndrome. This diet is based on low carbohydrate-high fat intakes. Dietary treatment is also therapeutic for inborn errors of metabolism such as aminoacdiopathies. We report a child with both

An isolate of Streptococcus intermedius from a brain abscess showed neuraminidase (sialidase), beta-D-galactosidase, N-acetyl-beta-D-glucosaminidase and N-acetyl-beta-D-galactosaminidase activities. The optimal pH values of these enzymes were 5.5-6.0, 5.5-6.0, 5.0-5.5 and 5.0-5.5, respectively. The

The communities of beneficial bacteria that live in our intestines, the gut microbiome, are important for the development and function of the immune system. Bacteroides species make up a significant fraction of the human gut microbiome, and can be probiotic and pathogenic, depending upon various
