Front Public Health 2020 8;8:587298. Epub 2021 Jan 8.

Department of Oncologic Gynecology, The First Hospital of Jilin University, Changchun, China.

Persistent infection with the carcinogenic human papillomavirus (HPV) is a prerequisite for the progression of cervical lesions and cancer. A growing body of research has focused on the functional role of the vaginal microbiota in the persistence of HPV infection.

Immunological design of commensal communities to treat intestinal infection and inflammation.

PLoS Pathog 2021 01 19;17(1):e1009191. Epub 2021 Jan 19.

MRC Centre for Molecular Bacteriology and Infection, Department of Infectious Disease, Imperial College London, London, United Kingdom.

The immunological impact of individual commensal species within the microbiota is poorly understood limiting the use of commensals to treat disease. Here, we systematically profile the immunological fingerprint of commensals from the major phyla in the human intestine (Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria) to reveal taxonomic patterns in immune activation and use this information to rationally design commensal communities to enhance antibacterial defenses and combat intestinal inflammation. We reveal that Bacteroidetes and Firmicutes have distinct effects on intestinal immunity by differentially inducing primary and secondary response genes. Read More

Fusobacterium nucleatum in biopsied tissues from colorectal cancer patients and alcohol consumption in Korea.

Sci Rep 2020 11 16;10(1):19915. Epub 2020 Nov 16.

Department of Laboratory Medicine and Research Institute of Bacterial Resistance, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea.

The roles of individual bacteria and their relationship in the development of colorectal cancer (CRC) remain unclear. We aimed to determine the prevalence of CRC-associated bacteria using quantitative real-time PCR (qPCR) or 16S rRNA analysis and the statistical correlations of patient demographics and clinical characteristics comprising alcohol consumption with CRC-associated bacteria. We determined the prevalence of five CRC-associated bacterial species in 38 CRC patients (39 samples) and 21 normal individuals using qPCR, and the relative abundance of bacterial taxa in the gut microbiome was assessed using 16S rRNA analysis.

Pathogen identification in culture-negative cerebrospinal fluid specimens of patients with purulent meningitis using next-generation sequencing technology.

Int J Clin Exp Pathol 2020 1;13(9):2427-2438. Epub 2020 Sep 1.

College of Life Science, Northwest University 229 North Taibai Road, Xi'an 710069, Shaanxi, P. R. China.

Antimicrobial therapy necessitates fast and accurate detection of pathogens in purulent meningitis (PM) diagnosis. Although considered a gold standard, the traditional bacterial detection and identification methods based on routine bacterial culture are time-consuming and show low sensitivity and specificity. In order to reduce PM-related deaths and improve the treatment efficiency, we employed trace DNA extraction technology and combined it with Next-Generation Sequencing technology for bacteria identification.

Mikrobiyol Bul 2020 Jul;54(3):404-417

Marmara University Faculty of Medicine, Department of Medical Microbiology, Istanbul, Turkey.

Gram-positive anaerobic cocci (GPAC), a large group of anaerobic bacteria, are the members of the normal microbiota that colonizes the skin and mucosal surfaces of the human body. However, in case of a wound or when the host becomes immunocompromised, GPAC can cause invasive and most frequently mixed infections. GPAC are the second most frequently isolated bacteria in anaerobic infections. Read More

The Alterations of Vaginal Microbiome in HPV16 Infection as Identified by Shotgun Metagenomic Sequencing.

Front Cell Infect Microbiol 2020 23;10:286. Epub 2020 Jun 23.

Women's Reproductive Health Laboratory of Zhejiang Province, Women's Hospital, Zhejiang University School of Medicine, Hangzhou, China.

The association of microbiome imbalance with cancer development is being one of the research hotspots. Persistent HPV infection is a causal event in cervical cancer initiation, but, little is known about the microbiome composition and function in HPV infection. Here we identified the compositional and functional alterations on vaginal samples from 27 HPV16 positive women and 25 age-matched HPV negative controls using shotgun metagenomic sequencing, to provide a comprehensive investigation describing the microbial abundances and enriched metabolic functions in cervicovaginal metagenomes.

Gallstone Disease and Microbiome.

Microorganisms 2020 Jun 2;8(6). Epub 2020 Jun 2.

Laboratory of Gastroenterology, Research Institute of Internal and Preventive Medicine-Branch of The Federal Research Center Institute of Cytology and Genetics of Siberian Branch of Russian Academy of Sciences, Novosibirsk 630089, Russia.

Gallstone disease (GSD) has, for many years, remained a high-cost, socially significant public health problem. Over the past decade, a number of studies have been carried out-both in humans and in animal models-confirming the role of the microbiota in various sections of the gastrointestinal tract as a new link in the etiopathogenesis of GSD. The microbiome of bile correlates with the bacterial composition of saliva, and the microbiome of the biliary tract has a high similarity with the microbiota of the duodenum. Read More
