24
What is the route of infection for canine adenovirus one
Oro nasal
25
What is the dissemination for canine adenovirus one
Virus replicates in tonsils then the following viremia there is viral replication in the liver, kidney, spleen, lungs
26
What are the clinical signs for canine adenovirus one
Most cases are asymptomatic. Can have peracute, acute or mild disease
27
Describe the clinical signs for the acute disease
Fever, anorexia, Lethargy, vomiting, diarrhea, hepatomegaly, abdominal pain
28
What will 20% of dogs get when they get infected with canine adenovirus one
Anterior uveitis and corneal edema. hepatitis Blueeye
29
How do you treat canine adenovirus one
Fluid therapy, antibiotics, antiemetics, antiacids
30
How is canine adenovirus one transmitted
Through feces and saliva. Once were covered dogs we should the virus in their urine for several months
31
How do you prevent canine adenovirus one
Vaccination
32
Describe canine adenovirus two
Mild respiratory disease. Causes tonsillitis, pharyngitis, bronchitis, bronchopneumonia. Involved in the tracheobronchitis infection kennel cough
33
What is the family for para influenza
Paramyxoviridae
34
Describe para influenza
Highly contagious upper respiratory tract infection which is an important cause of tracheobronchitis. Usually does not cause a severe disease but to make the dog more susceptible to secondary bacterial and viral infections
35
What is infectious tracheobronchitis
Highly contagious, acute disease that is localized in the airways. Can be caused by one or more infectious agents such as canine adenovirus two, para influenza virus, Bordetella bronchiseptica
36
What are the clinical signs of infection is tracheobronchitis
Sudden onset of severe productive or nonproductive cough. Cough is worse worse with exercise, excitement, pressure on the neck from collar. Trachea palpation induces cough on GPE. Can also have gagging, retching or nasal discharge
37
What is the treatment for infectious tracheal bronchitis
In most dogs the diseases self-limiting with resolution of clinical signs into weeks. Rest for 7 to 14 days to limit constant irritation of airways caused by coughing. Cough suppressant's or antibiotics may be prescribed if the condition persists
38
How do you prevent infections tracheobronchitis
Isolate sick animals. If it's at a kennel evacuate the kennel for 1 to 2 weeks and disinfect
39
What is the family for parvovirus
Parvoviridae
40
Describe the structure of the parvovirus
Non-envelope DNA virus
41
Describe canine parvovirus type two
Has two strains type a and type B.
42
What can canine parvovirus type two infect
Dogs, wolves, coyotes
43
What are the risk factors for canine parvovirus type two
Season. More likely in the summer months. If a Rottweiler, Doberman, pitbull, Labrador retriever. If six weeks to six months old. If not vaccinated
44
What is the route of infection for parvovirus
Fecal to oral
45
What is the initial replication cycle of parvovirus
The laryngeal tissues, virus is spread to other tissues and organs by the bloodstream. Infects and destroys rapidly dividing cells
46
What happens if parvovirus destroys the precursor cells of white blood cells
Leukopenia
47
What happens if parvovirus destroys the intestinal crypt cells
Shortened villi, malabsorption, diarrhea
48
What happens if a neonatal puppy is infected with parvovirus
Results in myocarditis and death. Some puppies may survive but with a lifelong cardiac condition
49
What is the incubation period for parvovirus
4 to 14 days
50
What are the clinical signs of parvovirus
Anorexia, vomiting, hemorrhagic diarrhea, weight loss, Lethargy. Severe disease results in sepsis. Can be fatal
51
What is the treatment for parvovirus
Hospitalization with aggressive supportive treatment, IV fluids, antibiotics, anti-vomiting, anti-acid, analgesic
52
What happens if an animal survives parvovirus
Lifelong immunity after natural infection
53
Describe the transmission of parvovirus
Virus is shed and high amounts in feces one clinical signs are present. Virus may also be shed after late into incubation period for a limited time after recovery. 2 to 3 weeks. Direct contact with contaminated stool surfaces bulls collars and leashes. Flies can carry contaminated fecal matter to food bowls. Spread by Hans and clothing of people in contact with affected dogs
54
How long can parvovirus stay in the soil
Months
55
How do you prevent and control parvovirus
Isolation of sick animals, gloves and protective clothing, disinfection, vaccination
56
What is the family of the coronavirus
Coronaviridae
57
Describe the structure of a coronavirus
Envelope RNA virus
58
What is the root of infection for the coronavirus
Fecal to oral
59
What is the pathogenesis of the coronavirus
Affects the epithelial cells of the intestinal villi but not the crypt cells
60
What are the clinical signs of the coronavirus
Mild gastroenteritis, anorexia, Lethargy
61
What is the transmission for the coronavirus
Virus is shed in feces for two weeks
62
What is the incubation period for the coronavirus
1 to 3 days
63
What is the treatment for coronavirus
Most dogs recover without treatment. Some patients may need supportive care
64
How do you prevent and control coronavirus
Strict sanitation and isolation protocols, vaccine is available but controversial
65
What family is the papilloma virus in
Papillomaviridae
66
Describe the structure of a papilloma virus
Non-envelope DNA virus
67
Describe the thing that special about the Papilloma virus
Highly host specific and tissue restricted. Virus can only affect terminally differentiated cells like skin cells. Stimulates cell hyperplasia. Infected tissue forms benign tumors. Canine papillomas occurred on the lips and in the mouth of young dogs
68
How do you transmit the Papilloma virus
Close contact
