pathogenesis of meningoencephalitis - ️️-enters nasal passages via swimming (nasal lavage used to flush microbes) -burrows into cells, multiplies into nasal cells -move into brain low risk, highly fatal blood-brain barrier - ️️partially made of astrocytes will wrap around blood vessels for prevention of leakiness-prevents microbes from leaving vessels in CNS nervous cells - ️️microglial cells (phagocytic cells, able to clean up dead cells and debris in CNS) Meningies - ️️...

Uncoating - ️️-Removal of the capsid (protein layer made up of capsomere protein), releases genome in the cell -Capsomeres may be broken down and used by the cell -Capsid not always degraded, proteins may be present in the capsid to be used as enzymes inside of host cell in the viral replication cycle Adsorption - ️️-process of the virus binding or sticking to a surface of a host cell -Virus coincidentally bumps into a susceptible host cell-binds if the host tell receptors "mat...

1.State the medical relevance of the Enterobacteriacea family. - An estimated 80% of all clinical samples are positive for the presence of members of the family Enterobacteriaceae suggesting they are a significant source of bacterial pathogens to humans. Since this group is of medical relevance, we will use the Enterobacteriaceae as a pool of unknown bacteria from which your investigative team will select one organism and use the numerous biochemical tests to ascertain the bacteria's ident...
