Identity of streptococcal blood isolates and oral isolates from two patients with infective endocarditis.

J Clin Microbiol

Department of Oral Microbiology, School of Dentistry, Health Science Faculty, University of Copenhagen, Denmark.

Published: May 1995

The purpose of this study was to isolate streptococcal strains from the oral cavities of streptococcal endocarditis patients and compare these strains biochemically and genetically with the corresponding streptococcal blood isolates. Total identity was observed between the blood and oral cavity isolates from the two patients studied.

Investigating the role of intratumoral Streptococcus mitis in gastric cancer progression: insights into tumor microenvironment.

J Transl Med

Growing evidence implicates that intratumoral microbiota are closely linked to cancer progression; however, research on the role of these microbiota in the development of gastric cancer remains limited. Here, using 16 S rRNA sequencing, tumor tissue proteomics and serum cytokines analysis, we identified enrichment of specific microbial communities within tumors of gastric cancer patients, possibly affecting the tumor microenvironment by immune modulation, metabolic processes, and inflammatory responses. Based on the results of in vivo experiments and intratumoral microbiota analysis, we found that Streptococcus mitis can inhibit gastric cancer progression via suppressing M2 macrophage polarization and infiltration, as well as altering the intratumoral microbial community.

IgA nephropathy (IgAN) is related to the balance of gut microbiota. However, it is unclear whether changes in the gut microbiota can cause IgAN or attenuate its progression. This study employed IgAN and human microbiota-associated (HMA)-IgAN models to investigate the impact of IgAN on gut microbiota alteration and the mechanisms by which gut microbiota might trigger IgAN.

Chrysanthemum extract mitigates high-fat diet-induced inflammation, intestinal barrier damage and gut microbiota disorder.

An effective intervention for obesity without side effects is needed. Chrysanthemum may be the preferred choice due to its influence in the improvement of glycolipid metabolism. This study assessed the efficacy of chrysanthemum and its flavonoids in mitigating high-fat diet (HFD) induced obesity, focusing on the integrity of the intestinal barrier, inflammation, and gut microbiota.

Background: Patients after transcatheter pulmonary valve implantation (TPVI) are at increased risk for infective prosthetic valve endocarditis. Diagnosis of infective endocarditis (IE) following TPVI is particularly difficult due to impaired visualization of the transcatheter pulmonary valve (TPV) with echocardiography [Delgado V, Ajmone Marsan N, de Waha S, Bonaros N, Brida M, Burri H, et al. 2023 ESC guidelines for the management of endocarditis.

A Chain of Events Leading to Posttraumatic Subacute Meningitis.

There are few reports that discuss the nebulous entity known as posttraumatic subacute meningitis. Herein, we describe a case where a male was found deceased with Streptococcus pyogenes meningitis 7 days after experiencing head trauma inflicted with a tow chain. Computed tomography scan prior to death revealed a scalp laceration with subcutaneous gas and a subdural hematoma.
