PPT-Infections in immunocompromised host

Objectives Briefly outline various immunodeficient states and enumerate common infections in particular immunodeficiency states Discuss pathogenesis and transmission of infections in immunocompromised host. Infectious Agents of Animals . and Plants. Chapter 14. What am I?. Structure and Classification of Animal Viruses. Classification of animal viruses. Taxonomic criteria based on. Genomic structure. DNA or RNA. Infection Transmission. Plus. Host Birth, Death. Purpose: What fraction of hosts must be vaccinated in order to eradicate disease?. Compartments & Virulence. S. usceptible, . I. nfective, .  Immunocompromised. An Immunocompromised host is a patient who does not have the ability to respond normally to an infection due to an impaired or weekend immune system. . This inability to fight infection can be caused by a number of conditions including:. an antigen . to stimulate the immune response through active . immunity. Stimulates . the proliferation of T and B cells, resulting in the formation of effector and . memory. . cells – stimulates acquired immunity without disease pathology. Matt Resnick, Riley . Fosnot. , Adam Fields, Brandon Archibald. Overview. What is a Virus?. A microscopic. , . nonliving. particle that survives off of . host-cells. Simple structure made up of proteins and genetic material. Chapter 4. Introduction. Molecules recognized as “non-self” are antigens. Several mechanisms to protect itself . First level of protection include physical and biochemical-skin, acid in stomach. Second level of protection phagocytic cells, enzymes, and proteins. K berry. . Affect the skin or mucous membranes of face or oral cavity.. Oral tissues are a frequent site for primary infections and also when there is reactivation of latent viruses.. Most do not require specific treatment and are self limiting in otherwise healthy individuals.. Outcomes of the virus infection for the host . In the previous few chapters we have looked at . aspects of . the virus replication cycle that culminate in . the exit . of infective progeny . virions. A wide range of parasitic infections can involve the skin and subcutaneous tissues. Depending on the species of parasite, this involvement may be transient, the parasite passing through the skin on it August 2022 Immunization is one of the most important accomplishments in public health. Over the past 50 years, immunization has led to the elimination, containment and control of diseases that were Pulmonary infection. Dr. . Maha. . Arafah. 2013. At the end of this lecture, the student should be able to:. A] Understand that . pneumonia . is an inflammatory condition of the lung characterized by consolidation (solidification) of the pulmonary tissue.. :. Infection: The invasion of the host tissues by pathogenic microorganisms, their multiplication and production of harmful effects. . Pathogenic organisms:. The organisms which produce harmful effects or disease. . exanthem. :. Exanthem. is the term classically used to describe a widespread rash associated with fever in childhood.. Maternal antibody gives protection for the first 6–12 months of life and infection occurs thereafter.. diseases are particularly important causes of death among. . the elderly, people with the acquired immunodeficiency. . syndrome (AIDS), persons with chronic diseases, and. . patients. . receiving immunosuppressive drugs.
