The cell-surface receptors have two functions: they initiate the phagocytosis of the pathogen, and they stimulate a program of gene expression in the host cell for stimulating innate immune responses. The soluble receptors also aid in the phagocytosis and, in some cases, the direct killing of the pathogen. Phagocytosis is the process of taking in particles such as bacteria, parasites, dead host cells, and cellular and foreign debris by a cell. It involves a chain of molecular processes. Phagocytosis occurs after the foreign body, a bacterial cell, for example, has bound to molecules called "receptors" that are on the surface of the phagocyte.

This article proposes to discuss, first, the protective activity of phagocytes, then some of their acquired disorders, and, finally, their genetic by: 2. Bacterial Defense against Phagocytosis Resistance to phagocytic ingestion is usually due to a component of the bacterial cell surface (cell wall, or fimbriae, or a capsule). Listeria induces its own movement through a remarkable process of host cell actin polymerization and formation of microfilaments within a comet-like tail. Define phagocytic. phagocytic synonyms, phagocytic pronunciation, phagocytic translation, English dictionary definition of phagocytic. it's often helpful to consider the patient's history and symptoms in terms of the four components of specific host resistance: antibody, complement, phagocytic cells, and cell-mediated immunity.

EVASION OF HOST DEFENSES. Some pathogenic bacteria are inherently able to resist the bactericidal components of host tissues. For example, the poly-D-glutamate capsule of Bacillus anthracis protects the organisms against cell lysis by cationic proteins in sera or in phagocytes. The outer membrane of Gram-negative bacteria is a formidable. Mims' Pathogenesis of Infectious Disease is the landmark book in the field of infectious disease. The new, revised edition of this work provides a comprehensive, up-to-date description of the mechanisms of microbial infection and the pathogenesis of infectious disease. Phagocytosis (from Ancient Greek φαγεῖν (phagein), meaning 'to eat', and κύτος, (kytos), meaning 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ μm), giving rise to an internal compartment called the is one type of endocytosis.
