Transcript

  • 1. Rabies
virus
 •  Virus
family
–
Rhabdoviridae
 –  single‐stranded
RNA
genomes
 http://www.cdc.gov/rabies/virus.html –  protein
capsid
is
bullet‐shaped,
enveloped
 •  Signs
&
symptoms:
Headache,
fever,
agitaAon,
 confusion,
excessive
salivaAon
(foaming
of
the
mouth),
 hydrophobia
(fear
of
water),
hallucinaAons,
death.
 •  Helical
ribonucleoprotein
core
(RNP)
and
a
surrounding
 envelope
of
glycoprotein.
 •  No
specific
treatment,
disease
usually
fatal,
although
 there
are
a
series
of
shots
to
prevent
virus
from
taking
 hold.
 –  100%
fatal
virus
unless
intervenAon
is
immediate

  • 2. HepaAAs
C
virus
 •  Flaviviridae
virus
family
 •  Causes
HepaAAs
C,
the
symptoms
are
decreased
appeAte,
 faAgue,
abdominal
pain,
jaundice,
itching,
and
flu‐like
 symptoms.
If
serious
condiAons
go
untreated,
it
could
cause
 liver
failure
 •  Treatment
isn’t
always
necessary
if
not
very
serious
but
a
 combinaAon
of
anAviral
medicaAons
will
treat.
If
very
serious
 liver

damage
occurs,
liver
transplant
may
be
necessary
but
 will
not
cure
of
HCV.
 •  The
nucleic
acid
consists
of
single‐stranded
RNA
surrounded
 by
an
polyhedral
protein
capsid.

 •  This
virus
has
a
lipid
envelope


  • 3. Giardia
lamblia
 •  Giardia
lamblia
is
from
the
ProAst
kingdom
 •  Giardia
lamblia
is
pear‐shaped
with
8

 
flagella.

 http://www.nbbcfood.info/ foodmatters/foodsafetyatoz/ images/48fsm3giardial.jpg •  It
causes
giardiasis.

 –  Symptoms
are
diarrhea,
nausea,
gas,
and
abdominal
cramps
 •  People
become
infected
by
drinking
water
that
is
fecally
 contaminated
or
from
insufficient
hygeine
(daycare
workers
 handling
diapers
from
infected
children)
 •  Some
people
may
not
show
symptoms
 •  Giardiasis
may
go
away
on
its
own
but
is
best
treated
with
 medicine
like
metronidazole
 •  2.5
million
people
in
the
