1) Picornaviridae are enveloped viruses
F
2) The resistance of Picornaviridae is low, they cannot survive in the environment

T
4) Teschovirus is resistant, it remains infective in the faeces for a few weeks
T
5) Teschen and Talfan disease are caused by different virulence variants of the same virus
T
6) Dogs and cats can be infected with Teschen disease virus
F
7) Teschen disease virus can be present in pork meat
T
8) The virus of Teschen disease is shed in the faeces for several weeks after infection
T
9) The main clinical sign of Teschen disease in sheep is pneumonia
F
10) Lameness is a typical clinical sign of Teschen disease
T
11) Teschen disease occurs in cattle, sheep and pigs
F
12) Enteritis and pneumonia are frequent postmortem lesions of Teschen disease
F
13) Enlargement of the spleen and haemorrhages are typical postmortem lesions of Teschen disease
F
14) Teschen disease is frequent all over the world
F
15) The Teschen disease virus infects the animals per os
T
.
.
17) Talfan disease can be seen in animals below 4 months of age
T
18) Talfan disease is a disease of pigs
T
19) The clinical signs of Talfan disease are more severe than that of Teschen disease
F
20) Talfan disease occurs in any age groups
F
21) Inactivated vaccines are widely used in Europe to prevent Talfan disease
F
22) Haemorrhages are typical postmortem lesions of Talfan disease
F
23) Flaccid paralysis is a typical clinical sign of Talfan disease
T
24) Vesicles can be seen in the liver in the case of swine vesicular disease
F
25) Swine vesicular disease virus cannot cause viraemia
F
26) Swine vesicular disease is a zoonosis
F
27) Swine vesicular disease virus can cause vesicles on the snout of pigs
T
28) The resistance of swine vesicular disease virus is very low; it cannot survive in the environment
F
29) Haemorrhages in the serous membranes can be frequently seen postmotem in the case of swine vesicular disease
F
30) The mortality of swine vesicular disease is 40-50%
F
31) Swine vesicular disease is frequently seen in Europe
F
32) Swine vesicular disease virus replicates in the epithelium of the throat and tonsils
T
33) Only pigs are susceptible to swine vesicular disease virus
T
34) The VES infection results in clinical signs similar to that of FMD
T
35) The VES virus can survive in water for 2 weeks
T
36) The primary source of VES infection is sea origin feed
T
37) VES causes the highest mortality in pregnant sows
F
38) VES causes mortality in piglets
T
39) VES is more contagious than FMD
F
40) Haemorrhages in the parenchymal organs are frequent postmortem lesions of avian encephalomyelitis
F
41) There is germinative spread in the case of avian encephalomyelitis
T
42) Tremor is a typical clinical sign of avian encephalomyelitis
T
43) Germinative infection can happen in the case of duck hepatitis
T
44) Spasmodical paddling is a frequent clinical sign of duck hepatitis
T
45) The resistance of duck hepatitis A virus is high
T
46) Ducks are infected with the duck hepatitis A virus generally per os
T
47) Duck hepatitis cannot be prevented with vaccination
F
48) Duck hepatitis A virus is shed in the faeces
T
49) Encephalomyocarditis virus is shed in the faeces by infected animals
T
50) Encephalomyocarditis virus infects animals mainly per os
T
