When his boss called to complain that the time-sensitive documents he was waiting for still hadn't arrived, Victor worried that the courier responsible for delivery may secretly be on their competitor's payroll and had sabotaged them on purpose.
Virulence factors are molecules produced by pathogens (bacteria, viruses, fungi and protozoa) that contribute to the pathogenicity of the organism and enable them to achieve the following: 1  colonization of a niche in the host (this includes attachment to cells). 2  immunoevasion, evasion of the host's immune response.
Identify the virulence factors that are expressed by drug resistant strains of Staphylococcus aureus, Clostridium difficile, Enterococcus faecium and faecalis, and carbapenem-resistant Enterobacteriaceae. List the risk factors and clinical syndromes that are associated with these drug resistant organisms.
