To review:
The influence of the hemolysins, leukocidins, coagulase, kinases, and hyaluronidase, siderophores, and IgA proteases to the pathogenicity of microbes.
Introduction:
Microorganisms that have the ability to cause infectious diseases are called as pathogens. This ability is denoted as the pathogenicity of a microbe. Such microorganisms include bacteria,

Microbiology: An Introduction
- All the following would be of benefit to extracellular pathogens, except A) O the presence of a capsule B) O ability to prevent the fusion of a phagosome and lysosome C) O ability to prevent of opsonization D) O ability to alter cell surface proteins via phase variation E) O There are no exceptions; all are of benefit to extracellular pathogens.arrow_forwardExplain the process of Quorum Sensing in coordinating the production of virulence factors in a host.arrow_forwardDifferent strains of Streptococcus pyogenes have different virulence factors, giving these microbes much versatility. Virulence factors include which of the following? Choose one or more: A.A capsule that, when thick, will help the organism avoid phagocytosis by macrophages B.A cell wall containing lipoteichoic acid, thought to facilitate adherence to pharyngeal epithelial cells C.Enzymes that lyse blood cells (streptolysins) D.The production of several endotoxins called streptococcal pyogenic endotoxins (SPEs)arrow_forward
- Mycobacterium tuberculosis recruits phagocytes to the site of infection. Based on this information, which of the three methods shown here does the bacterium likely use to avoid being destroyed?arrow_forwardExplain the role of LPS in pathogenesis.arrow_forwardWhich of the following types of antimicrobial drugs make microbes more susceptible to osmotic pressure? 1) drugs that inhibit nucleic acid synthesis O 2) drugs that inhibit metabolic pathways 3) drugs that inhibit cell wall synthesis 4) drugs that block a pathogen's recognition of its host 5) drugs that inhibit protein synthesisarrow_forward
- Identify three bacterial structures linked to virulence and pathogenicity.arrow_forwardDiscuss why it is important for us to conduct research at the basic level of physiology in order to better understand what makes Mycobacteria latent or grow during an infection so that we can design new and/or better treatment modalities.arrow_forwardEnumerate and briefly explain the steps in pathogenesis of COVID-19 with this format: Entry of the pathogen into the body > Attachment of the pathogen to some tissue(s) within the body > Multiplication of the pathogen > Invasion or spread of the pathogen > Evasion of host defenses > Damage to host tissue(s)arrow_forward
- Match the PAMP to the type of pathogen it is specific to. 1) Peptidoglycan 2) Lipopolysaccharides 3) RNA 4) DNA Here is the options: a) Gram-negative bacteria b) Viruses c) Gram-positive bacteriaarrow_forwardFor each of the following: Cyanobacteria, Coronavirus, Chytrids, Ciliates, and Chronic wasting disease. Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.arrow_forwardWrite a short description on ALL of the following: a) The application of turbidostat against chemostat b) The need of using cell immobilisation over free cell systemarrow_forward
