HERPES HARDCORE

Question 1

Alphaherpesviruses are host specific slowly multiplying (>24hrs) viruses

Answer 1

F
Alpha = Fast replication → Rapid destruction of host cells + Boarder Host Range
Beta = Slower replication + More limited host range
Gamma = Variable replication → Very limited host range

Question 2

Some herpesviruses have a broad host spectrum (euryxen

Answer 2

T
alphaherpesvirinae

Question 3

Herpesviruses are typically stenoxen viruses, but there are significant exceptions

Answer 3

T

Question 4

Because the genome of herpesviruses is very stable, no attenuated mutant vaccine strains are available

Answer 4

F
Not stable we have deletion and point mutations on the genome

Question 5

Infectious bovine vulvovaginitis virus strains cause abortions and foetal deformities

Answer 5

F
Sporadic abortions yes but not together with IPV
Also never foetal deformities (monsters)

Question 6

The use of marker vaccines can help the eradication of infectious bovine rhinotracheitis virus

Answer 6

T
Marker vaccines together with selection procedure if seropositive are more than 10% of the total tested

Question 7

Antibodies against infectious bovine rhinotracheitis virus (IBRV) might be detected in the milk

Answer 7

T + blood/serum
Also sampling for direct detection can be:semen + vaginal discharges + ocular discharges + nasal discharges

Question 8

Answer 8

T

Question 9

The infectious bovine rhinotracheitis virus (IBRV) causes haemorrhagic gastroenteritis

Answer 9

Answer 13

T
bronchopneumonia

Question 14

Infectious Bovine Rhinotracheitis may cause inflammation of conjunctiva

Answer 14

T
yes and ocular discharge with the virus for swabs

Question 15

In Hungary the IgE-negative marker vaccine is to be used in the control of Infectious Bovine Rhinotracheitis

Answer 15

T

Question 16

Infectious Bovine Rhinotracheitis is rapidly spread within the herd

Answer 16

F
IBR slowly
MCF rapidly

Question 17

Infectious Bovine Rhinotracheitis spreads slowly within a herd

Answer 17

T

Question 18

We can see characteristic clinical signs of Infectious Bovine Rhinotracheitis in day-old calves

Answer 18

F

Question 19

Infectious Bovine Rhinotracheitis is rare, BHV-1 only affects cattle

Answer 19

F+ other ruminants too

Question 20

In the transmission IBRV, the most important route is the germinative route

Answer 20

F
aerogenous

Question 21

Genital form of IBR is often followed by abortion

Answer 21

F
IPV never occurs with abortion

Question 22

Bovine Herpes virus 2 frequently causes abortion

Answer 22

F
affects the teats and the udder and rarely spread to perineal region or generalised Pseudo lumpy skin disease

Question 23

Bovine herpesvirus 2 is the most frequent primary cause of mastitis in cattle

Answer 23

F
most frequent is bacterial infections?

Question 24

Inclusion body rhinitis is predisposing to fatal respiratory disease in pigs

Answer 24
