3D reconstructions of parasite development and the intracellular niche of the microsporidian pathogen ... - Nature.com

Abstract Microsporidia are an early-diverging group of fungal pathogens with a wide host range. Several microsporidian species cause opportunistic infections in humans that can be fatal. As obligate intracellular parasites with highly reduced genomes, microsporidia are dependent on host metabolites for successful replication and development. Our knowledge of microsporidian intracellular development remains rudimentary, and our understanding of the intracellular niche occupied by microsporidia has relied on 2D TEM images and light microscopy. Here, we use serial block-face scanning electron microscopy (SBF-SEM) to capture 3D snapshots of the human-infecting species, Encephalitozoon intestinalis , within host cells. We track E. intestinalis development through its life cycle, which allows us to propose a model for how its infection organelle, the polar tube, is assembled de novo in developing spores. 3D reconstructions of parasite-infected cells provide insights into the physical intera...

Psychological Disorders: Types and Examples - Verywell Mind

The term psychological disorders is sometimes used to refer to what are more frequently known as mental disorders or psychiatric disorders. Mental disorders are patterns of behavioral or psychological symptoms that impact multiple areas of life. These disorders create distress for the person experiencing the symptoms. The DSM-5-TR lists hundreds of distinct conditions. Anxiety and depression are among the most common types of mental health conditions that people experience. While the DSM provides diagnostic information about such conditions, including the age at which they typically appear, it does not provide guidelines for treatment or predictions related to the course of illness. While not a comprehensive list of every mental disorder, the following list includes some of the major categories of disorders described in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the fifth edition...
