PQS - Calicivirus Flashcards
Calicivirus can cause persisting infections in the tonsils
T
Also in nasopharyngeal mucousa
Sapoviruses cause gastrointestinal infections in human.
T
The VES infection results in clinical signs similar to that of FMD
T
The VES virus can survive in water for 2 weeks
T
Can survive in the environment for AT LEAST 2 weeks
The primary source of VES infection is sea origin feed
T
After a pig is infected, it can be transmitted from pig to pig
VES causes the highest mortality in pregnant sows
F
Low mortality rate, only weak piglets die
VES causes mortality in piglets
T
VES is more contagious than FMD
F
Lameness is one of the signs of vesicular exanthema in swine
T
Due to vesicles on the foot
Vaccines are ideally used for the prevention against swine vesicular exanthema
F
No vaccines available
Swine vesicular exanthema virus is present worldwide
F
In American countries
The Vesicular Exanthema of swine virus infects only pigs.
F
Seals too
Clinical signs of the Vesicular Exanthema of swine can be similar to the Foot and Mouth
disease.
T
Only differentiated by Lab work!!
VES can be easily differentiated from FMD by the character of the vesicles.
F
Vesicular exanthema of swine is sea-mammal origin
T
We can differentiate VES from FMD by the lack of lameness.
F
Several serotypes of Swine Vesicular Exanthema virus can be detected in fishes.
T
Rodents are the reservoir hosts of Vesicular Exanthema of Swine virus.
F
Midges are the main vectors of the Vesicular exanthema of swine virus.
F
Feline calicivirus is carried and shed by vaccinated animals too
T
The feline calicivirus is shed in excretes
T
The feline calicivirus infection can be recognised by the ulcers seen on the tongue
T
Most characteristic
The feline calicivirus infection can cause the limping of kittens
T
The limping syndrome
Cat queens frequently abort in the acute phase of Feline Calici virus infection.
F
Bordetella bronchiseptica can complicate calicivirus infection of cats
T
Virulent strains of feline calicivirus can cause severe systemic syndrome
T
Feline calicivirus can cause persisting infection In the tonsils
T
Cats may carry and shed feline calicivirus for several month or years
T
Feline caliciviruses cause haemorrhagic enteritis
F
Some variants of feline calicivirus may escape vaccine induced protection
T
Cats shed the Feline calicivirus for several weeks.
T
Minimum 30 days
Lameness and fever are possible clinical signs of Feline calicivirus infection.
T
Oral erosions are signs of Feline calicivirus infection.
T
Virulent strains of the Feline calicivirus can cause systemic disease with mortality.
T
Virulent systemic feline calicivirus causes more severe symptom in kittens
F
More severe in adults
FCV infection results in a two-phase fever.
T
Infected cats carry feline calicivirus at least for a month.
T
30 days
Feline calicivirus may be shed by urine and faeces.
T
But mainly in saliva
Feline calicivirus infection may cause pyrexia and lameness.
T
Erosions on the oral mucosa are frequent signs of feline calicivirus infection.
T
Feline calicivirus has a very characteristic biphasic fever.
T
RHD induces clinical signs mostly in animals younger than 2 months
F
Clinical signs more frequently over 8 weeks of age
RHD virus is used for biological control of rural rabbits
T
In Australia and New Zealand
RHD virus propagates in the liver of the infected animals
T
RHD virus can be propagated in cell culture
F
Vaccines against RHDV-1 induce protection against RHDV-2 too
F
They are antigenitically different
Encephalitis is a frequent sign of the rabbit haemorrhagic disease
F
Rabbit haemorrhagic disease virus is transmitted by mosquitoes
F
Rabbit haemorrhagic disease is characterized by rapid progression
T
Australia is free of rabbit haemorrhagic disease
F
They use it as pest control
There are no vaccines available against rabbit haemorrhagic disease
F
Inacitavted vaccines used in combination with myxomatosis
Up to 100% of susceptible rabbits may be killed by rabbit haemorrhagic disease
T
The incubation time of rabbit haemorrhagic disease is usually over 3 weeks
F
1-4 days
Hepatic necrosis is a frequent lesion of rabbit hemorrhagic disease
T
Rabbits over 1 month of age become susceptible to the Rabbit Haemorrhagic Disease virus.
F ?? True in studysmarter
Type 1: Over 8 weeks of age
Type 2: All ages, especially young ones - Even 15-20 day old rabbits
The Rabbit Haemorrhagic Disease is present only in Australia
F
Rabbit Haemorrhagic Disease virus usually causes death in 1-3 weeks old rabbits.
F
Can cause infection from 15-20 day old rabbits - 2 week old
There are no vaccines available against Rabbit Haemorrhagic Disease.
F
The haemorrhage in RHD is the result of virus multiplication in the liver.
T
In RHD pathology we can see haemorrhages and infarcts in the kidney.
T
Vaccine against RHD is produced in rabbits.
T
From the liver
RHD causes airborne infection.
T
The Rabbit Haemorrhagic Disease is a chronic illness with low morbidity.
F
It is acute and have high mortality
