Document Summary

Lecture 37: know the 3 most common pathogens. Bacterial, viral, and fungal: know what the meninges is and why an infection can lead to death so quickly. Chickenpox and shingles; develops characteristic lesions on face and upper trunk erupt, fill with pus, rupture, and covered by scabs: know the major antigens of influenza viruses. Neuraminidase (involved in viral release from host cell) and hemagglutinin (involved in viral attachment into host cells: describe antigenic drift and antigenic shift. Antigenic drift is the mutation of genes over time and antigenic shift is the shuffling of rna segments: be able to describe how influenza viruses are named. By undergoing antigenic shift: know what happened in the 1918 pandemic. About 25% of all american became ill; mortality rates were over 2. 5%;
