Chapter 6, Problem 2R

For 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.

Simple but creative caption on a poster about noncommunicable diseases caused by having unhealthy lifestyle.

A phagocyte enters tissues by: chemotaxis leukocytosis diapedesis margination

The first stage of pathogenesis is evasion of the hosts immune system entry to the host colonization of the host replication in the host adhesion to the host

The simplest correct definition of disease is:     cellular dysfunction     organ failure     infection by a microbe     cellular destruction by chemicals

What happens during the 'incubation period'?   The virus is cleared from the body by the immune system This period commonly lasts for a few days Virus replication happens at an intracellular level This period commonly lasts for a few hours

Regular herpesvirus-mediated cold sores or genital sore flare-ups are caused by reinfection by the same herpesvirus strain reinfection by a closely related herpesvirus of a different strain copies of the herpesvirus genome permanently maintained in host cell cytoplasm copies of the herpesvirus genome permanently maintained in host nuclei

Why is it so dangerous for a patient to have a systemic infection?

An infection that stays in a specific location is a infection. O Focal O Localized O Systemic
