In response to environmental stressors such as blast fungal infections, rice produces phytoalexins, an antimicrobial diterpenoid compound. Together with momilactones, phytocassanes are among the major diterpenoid phytoalexins. The biosynthetic genes of diterpenoid phytoalexin are organized on the chromosome in functional gene clusters, comprising diterpene cyclase, dehydrogenase, and cytochrome P450 monooxygenase genes. Their functions have been studied extensively using in vitro enzyme assay systems. Specifically, P450 genes (CYP71Z6, Z7; CYP76M5, M6, M7, M8) on rice chromosome 2 have multifunctional activities associated with ent-copalyl diphosphate-related diterpene hydrocarbons, but the in planta contribution of these genes to diterpenoid phytoalexin production remains unknown...

Many wastewater treatment technologies have been shown to remove bacterial pathogens more effectively than viral pathogens and, in aquatic environments, levels of traditional faecal indicator bacteria (FIB) do not appear to correlate consistently with levels of human viral pathogens. There is, therefore, a need for novel viral indicators of faecal pollution and surrogates of viral pathogens, especially given the increasing importance of indirect and direct wastewater reuse. Potential candidates include bacteriophages (phages) and the study described here sought to elucidate the relationship between three groups of phages (somatic coliphages (SOMPH), F-RNA coliphages (F-RNAPH) and human-specific phages infecting B...

Intracranial complications of paranasal sinusitis have become rare due to the use of antibiotics nowadays. However, several cases have been reported due the ability of paranasal sinusitis to cause serious complications. Once the infection spreads over the cranial structure, it could infect the orbits, underlying bones, meninges, adjacent veins, and brain. Subdural empyema is a rare but potentially life-threatening complication following paranasal sinusitis and should be considered as a neurological emergency...

The modern concept of epithelial-endothelial dysfunction and epithelial-endothelial distress-syndrome associated with pyo-inflammatory ENT diseases is presented. It has provided a basis for the analysis of the initial stages of etiopathogenesis of acute and chronic inflammation in the ENT system including the mucous and associated lymphoid tissues as well as the Pirogov-Waldeyer limphopharyngeal ring making up the first protective barrier. The leading role of dysbiosis of synanthropic microflora and endotoxins of the Gram-negative bacteria in the mechanisms of regional responsiveness of the organism to the infection and chronic endotoxic aggression is demonstrated...

Inflammatory myofibroblastic tumor (IMT) is a rare tumor in the central nervous system (CNS), mostly being extracranial. Approximately 100 sporadic cases have been reported in the literature. The rarity of the tumor, its various histopathological characteristics, and its variable aggressive course render it difficult to diagnose and treat. IMT is generally a histological diagnosis which is rarely suspected preoperatively. It mimics other intracranial tumors such as giant cell tumor, hemangiopericytoma, anaplastic meningioma, plasmacytoma, and lymphoma...

PURPOSE OF REVIEW: Studies in microbiota-mediated health risks have gained traction in recent years since the compilation of the Human Microbiome Project. No longer do we believe that our gut microbiota is an inert set of microorganisms that reside in the body without consequence. In this review, we discuss the recent findings which further our understanding of the connection between the gut microbiota and the atherosclerosis. RECENT FINDINGS: We evaluate studies which illustrate the current understanding of the relationship between infection, immunity, altered metabolism, and bacterial products such as immune activators or dietary metabolites and their contributions to the development of atherosclerosis...

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses...

Lyme borreliosis (LB) is the most prevalent tick-borne disease in Europe. Erythema migrans (EM), an early, localised skin rash, is its most common presentation. Dissemination of the bacteria can lead to more severe manifestations including skin, neurological, cardiac, musculoskeletal and ocular manifestations. Comparison of LB incidence rates in the European Union (EU)/European Economic Area (EEA) and Balkan countries are difficult in the absence of standardised surveillance and reporting procedures. We explored six surveillance scenarios for LB surveillance in the EU/EEA, based on the following key indicators: (i) erythema migrans, (ii) neuroborreliosis, (iii) all human LB manifestations, (iv) seroprevalence, (v) tick bites, and (vi) infected ticks and reservoir hosts...

Hyper IgM syndrome is a well known genetic (primary) immunodeficiency disorder which was first described in 1961. It is caused by B lymphocyte deficiency characterized by normal or elevated serum IgM levels and low or zero levels of IgG, IgA, IgE resulting from isotype-switching deficiency. Clinical manifestations are dominated by recurrent infections, especially involving the digestive tube of the ENT sphere and the lungs. This syndrome is caused by B-cell immunoglobulin class switch deficiency and decreased capacity to induce proliferation of T lymphocytes...
