Advancing Precision Vaccinology by Molecular and Genomic Surveillance of SARS-CoV-2 in Germany, 2021.

Clin Infect Dis 2022 Jun 25. Epub 2022 Jun 25.

Systems Medicine of Infectious Disease (P5), Robert Koch-Institute, Berlin, Germany.

Background: Comprehensive pathogen genomic surveillance represents a powerful tool to complement and advance precision vaccinology. The emergence of the Alpha variant in December 2020 and the resulting efforts to track the spread of this and other SARS-CoV-2 variants of concern led to an expansion of genomic sequencing activities in Germany.

Methods: At Robert Koch Institute (RKI), the German National Institute of Public Health, we established the "Integrated Molecular Surveillance for SARS-CoV-2" (IMS-SC2) network to perform SARS-CoV-2 genomic surveillance at the national scale, SARS-CoV-2 positive samples from laboratories distributed across Germany regularly undergo whole-genome sequencing at RKI.

[Neutropenic enterocolitis in the pediatric cancer patient].

Rev Chilena Infectol 2022 02;39(1):59-69

Hospital Clínico San Borja Arriarán, Chile.

Neutropenic enterocolitis (NEC) is a heterogeneous disease of the gastrointestinal tract with systemic response, that corresponds to a severe and life-threatening clinical condition in immunocompromised patients, especially in childhood cancer. The pathologic features are poorly understood, although its multifactorial cause of NEC is well established and it is associated with the cytotoxic effects of the chemotherapy agents used and recognized by the classic triad of fever, neutropenia, and abdominal pain, secondary to gastrointestinal injuries that alters mucosal permeability and helps intramural bacterial invasion. NEC is truly a clinical challenge that requires an early diagnosis and a multidisciplinary approach including basic laboratory and imagological tests in high complexity centers. Read More

Antibiotics for uncomplicated diverticulitis.

Cochrane Database Syst Rev 2022 06 22;6:CD009092. Epub 2022 Jun 22.

Department of Surgical Gastroenterology , Hvidovre University Hosipital , Copenhagen, Denmark.

Background: Diverticulitis is a complication of the common condition, diverticulosis. Uncomplicated diverticulitis has traditionally been treated with antibiotics, as diverticulitis has been regarded as an infectious disease. Risk factors for diverticulitis, however, may suggest that the condition is inflammatory rather than infectious which makes the use of antibiotics questionable. Read More

Saireito, a Japanese herbal medicine, alleviates leaky gut associated with antibiotic-induced dysbiosis in mice.

PLoS One 2022 15;17(6):e0269698. Epub 2022 Jun 15.

Department of Infectious Disease Control, Faculty of Medicine, Oita University, Yufu, Oita, Japan.

Antibiotics disrupt normal gut microbiota and cause dysbiosis, leading to a reduction in intestinal epithelial barrier function. Disruption of the intestinal epithelial barrier, which is known as "leaky gut", results in increased intestinal permeability and contributes to the development or exacerbation of gastrointestinal diseases such as inflammatory bowel disease and irritable bowel syndrome. We have previously reported on a murine model of intestinal epithelial barrier dysfunction associated with dysbiosis induced by the administration of ampicillin and vancomycin. Read More

Sequence addition to the N- or C-terminus of the major capsid protein VP1 of norovirus affects its cleavage and assembly into virus-like particles.

Microb Pathog 2022 Jun 11;169:105633. Epub 2022 Jun 11.

The Sixth People's Hospital of Zhengzhou, Zhengzhou, 450000, China. Electronic address:

Norovirus (NoV) infection is a leading cause of non-bacterial gastroenteritis worldwide and there are currently no effective therapeutics available to target the virus. The norovirus major capsid protein VP1 is a potential candidate for the development of vaccines due to the similar morphology and immunogenicity of its assembled virus-like particles (VLPs) compared to native virions. In this study, we explored the effects of N- and C-terminal sequence additions to the VP1 of a GII. Read More

Universite Paris-Saclay, INRAE, AgroParisTech, Micalis Institute, Domaine de Vilvert, 78352, Jouy en Josas, France.

Background: Innate immunity genes have been reported to affect susceptibility to inflammatory bowel diseases (IBDs) and colitis in mice. Dectin-1, a receptor for fungal cell wall β-glucans, has been clearly implicated in gut microbiota modulation and modification of the susceptibility to gut inflammation. Here, we explored the role of Dectin-1 and Dectin-2 (another receptor for fungal cell wall molecules) deficiency in intestinal inflammation. Read More

Gut microbiota in mucosa and feces of newly diagnosed, treatment-naïve adult inflammatory bowel disease and irritable bowel syndrome patients.

Gut Microbes 2022 Jan-Dec;14(1):2083419

Center for Translational and Clinical Research, University of Zagreb School of Medicine, Zagreb, Croatia.

The knowledge on how gut microbes contribute to the inflammatory bowel disease (IBD) at the onset of disease is still scarce. We compared gut microbiota in newly diagnosed, treatment-naïve adult IBD (Crohn's disease (CD) and ulcerative colitis (UC)) to irritable bowel syndrome (IBS) patients and healthy group. Mucosal and fecal microbiota of 49 patients (13 UC, 10 CD, and 26 IBS) before treatment initiation, and fecal microbiota of 12 healthy subjects was characterized by 16S rRNA gene sequencing.

Development of an ultra-sensitive single-tube nested PCR assay for rapid detection of Campylobacter jejuni in ground chicken.

Food Microbiol 2022 Sep 27;106:104052. Epub 2022 Apr 27.

Department of Human, Nutrition, Food and Animal Science, University of Hawaii at Manoa, 1955 East West Road, Agricultural Sciences Building 216, Honolulu, HI, 96822, USA. Electronic address:

Traditional culture-based detection methods for Campylobacteri jejuni, a leading cause of human bacterial gastroenteritis worldwide, are time-consuming, cumbersome, and lacking in reliability. While polymerase chain reaction (PCR) has been frequently used for pathogen testing, it might generate false-negative results due to inadequate sensitivity. This study was the first to explore novel single-tube nested PCR (STN-PCR) to detect pathogens in food. Read More

Salmonella enterica Serovar Typhimurium Induces NAIP/NLRC4- and NLRP3/ASC-Independent, Caspase-4-Dependent Inflammasome Activation in Human Intestinal Epithelial Cells.

Infect Immun 2022 Jun 9:e0066321. Epub 2022 Jun 9.

Department of Microbiology, University of Pennsylvaniagrid.25879.31 Perelman School of Medicine, Philadelphia, Pennsylvania, USA.

Salmonella enterica serovar Typhimurium is a Gram-negative pathogen that causes diseases ranging from gastroenteritis to systemic infection and sepsis. Salmonella uses type III secretion systems (T3SS) to inject effectors into host cells. While these effectors are necessary for bacterial invasion and intracellular survival, intracellular delivery of T3SS products also enables detection of translocated Salmonella ligands by cytosolic immune sensors.

α7 nicotinic acetylcholine receptor agonist GTS-21 attenuates DSS-induced intestinal colitis by improving intestinal mucosal barrier function.

Mol Med 2022 06 3;28(1):59. Epub 2022 Jun 3.

Department of Gastroenterology, The First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, 210029, Jiangsu Province, People's Republic of China.

Background And Aims: Cholinergic output, which could modulate innate immune responses through stimulation of α7 nicotinic acetylcholine receptor (α7nAChR), might be a target to minimize tissue damage in autoimmune disease.
