BIOL 2053 Lecture Notes - Lecture 39: Multiple Organ Dysfunction Syndrome, Virus, Cutaneous Condition
VARIO
LA VIRUS -SMALLPOX
↳dsDNA
.once the deadliest disease
. infection :aero solis ed virus from saliva -othroat →lymph
nodes →blood
.fever,muscle pain ,vomiting ,pustule formation
.death from multiple organ failure tuncontrollable
immune response
.used as bioterrorism !so was eradicated by vaccine campaigns !
HEPATITIS BVIRUS
↳HBV ,dsDNA
.
yapped genome of dsDNA a ssDNA
.transmitted through body fluids -saliva ,sweat ,semen ,milk ,wine ,faeces
. virus affects liver cells →jaundice →cirrhosis →lives cancel
. vaccine very effective!
HUMAN IMMUNODEFICIENCY VIRUS
↳HIV ,SSRNA t retrovirus
.envelope proteins kind to immune
all receptors G- cells )
;
virions taken into the all -endocytosis
reverse transcriptase in virion
synthesises RNA →DNA
•
integral integrates dsDNA into host
where viral DNA is transcribed t
translated .Resulting viral proteins trimmed by protease .
