VIRAL GIT - other - hepatitis E, astrovirus, enteroviruses, poliovirus, echovirus, coxachieviruses, hepatitis A, achivirus Flashcards
(11 cards)
Hepatitis E virus
it was first considered a calcivirus due to shape and size but now its got its own family
it infects the liver through the feacal oral route
fatilities with pregnant women
astroviruses
they cause diarrhoea not vomiting
less prevalent in adults
mild symptoms,
lasts 1-4 days
enteroviruses
LARGE GROUP
waterborne viruses
summar and autumn
most common - poliomyelitis (also save echo and coxsackie virus)
poliovirus
is an enterovirus and spread through contaminate water
3 stereotypes and 4 conditions
asymptomatic (most are)
1) minor polio - temporary fever - mails and sore throat
2) nonparylatic polio - invades CNS - muscle spasms and back pain
3) paralytic polio - invades the spinal cord and causes paralysis
echo virus
enterovirus
feacal oral route (causes cold and viral meningitis)
coxsackievirus
COXSACHIEVIRUS A
associated with lesions and fever that lasts days to weeks
this is usually sold limiting
lesions in mouth and throat
so we get sore throat, pain in swollwing and vomiting
hand, foot and mouth disease
coxsackie virus B
transmitted through the mouth
associated with myocarditis rather than the GI tract
invades pancreas and can cause diabetes through cellular destruction
hepatitis A
faecal oral route
enterovirus
survives for a long period (countertops and chopping boards - it’s also resistant to chlorine)
1 month incubation
fever fatigue nausea and anorexia
jaundice due to liver issues
achi virus - what is the genus and the host
genus - kobuvirus
human, pig, cat and dog
viral replication of achi - virus
enters through endocytis
released as viral RNA
host ribosome synthesises the protein
these proteins promote synthesis of new viral RNA and complete particles
symptoms of achi virus
damages the intestinal villi which leads to water loss and diarrhoea
