URT viruses Flashcards
Feline calcivirus SS, DS. RNA, DNA, enveloped?
ss RNA nonenveloped
hallmark of caclivirus that distinguishes it from herpes virus
oral ulcers on tongue, lips and nose
T/F there can be lifelong carriers of calicivirus
true
control of calicivirus?
biosecurity and prevention. quarantine isn’t 100% and neither is the vaccine.
what two species have caliciviruses
rabbit and cats
T/F if a rabbit is bleeding from its nose you should treat for URI
false. report to the state RHDV
what four species get herpes
bovine, equine, canine, feline
herpes virus: strand, type, key features
DS DNA, intranuclear inclusion bodies seen on histo, latent in sensory ganglia
which herpes virus doesnt commonly cause respiratory disease
canine herpesvirus. has to be welping puppies because low body temps
what causes the most common URI in cats
felid alphaherpes virus 1
DDX for sneezing conjunctivitis and uri in cats
FVR( alpha herpes), calicivirus
what is the most effective way to limit spread of herpes
quarantine in all species
which equine herpes strand causes respiratory disease
EHV1 and EHV4 is primarily resp while EHV1 more commonly goes neuro
what causes IBR
bovid Aherpes 1
where does alpha herpes replicate
mucous membranes in URT
bovine disease that causes necrotizing tracheitis and red nose
IBR (aherpes)
what is the strand type of influenza. what is their unique characteristic
SS RNA. can perform antigenic shift
what are the three characteristic signs of flu
high fever, dry cough, nasal discharge
paramyxoviruses: strand type, special characteristics
SS RNA. syncytial cell formations, and eosinophilic intracytoplasmic inclusions
BRDC:
IBR (aherpes), bovine parainfluenza 3 (PI3), Bovine respiratory syncytial virus (orthopneumovirus)
what is the common presentation of PI3 in cattle
subclinical disease
what are the general signs of canine distemper
acute disease fever, vomiting, nasal discharge, hard pad dz, encephalitis
what does the rib impression in lungs on necropsy mean
lungs cant deflate properly due to them being full of infection/inflammation
what BRDC affects adult cattle resulting in interstitial pneumonia
bovine resp syncytial virus (bovine orthopneumovirus)
