Unformatted text preview: Animal Science Test 3 Lecture 1 – Infectious Diseases What are some characteristics of viruses? Incapable of replicating outside of the host Use host cell proteins and structures to replicate RNA vs. DNA based viruses Cannot be treated with antibiotics because they are constantly changing What is coronavirus? Club like proteins on membrane that give crown like appearances Causes intestinal disease, respiratory diseases in humans What are characteristics of canine coronavirus Mild and self limiting and can be fatal (rarely) Vaccine exists but hard because strains are constantly changing What are characteristics of feline coronavirus? Mild and self limiting Can form felind infectious peritonitis Wet form – abdominal and thoracic fluid accumulation Dry form Both are untreatable and fatal – associated with stress and overcrowding What are some characteristics of Dog/Cat Herpes virus Linear double stranded DNA Remain latent after primary infection which leads to chicken pox and cold sores What are some characteristics of canine herpes virus Replicates at lower then normal body temperatures Only considered serious with bitches with primary periparturient infections Litter may be lost due to no immunity and unable to replicate below normal temp What are some characteristics of feline herpes virus? Cause of upper respiratory/ocular disease Damages upper respiratory tract and causes chronic respiratory disease Vaccines are routine but does not prevent infection – decreases signs What is Parvo Viruses? Single stranded DNA genome Viruses codes for very few genes requires cell machinery for replication What are some characteristics of canine parvovirus? Causes intestinal disease – rapidly dividing cells of GI tract Adults – self limiting diarrheal disease – can be fatal in pups Can be prevented by good hygiene and vaccination Causes diarrhea, cardiac syndrome, dehydration, vomiting, loss of appetite What are some characteristics of feline parvovirus Intestinal disease and immune cell depletion Adults – self limiting, can be fatal in kittens, Can be prevented by good hygiene Causes low WB in kittens, fever, diarrhea What is Adenovirus? Cause of two canine conditions: Infectious Canine Hepatitis (CAV-1) – respiratory, eye infections Infectious Tracheobronchitis (CAV-2) – kennel cough What is the parainfluenza virus? Causes canine parainfluenza-3 Causes infectious trachelbronchitis – can be controlled by vaccination What is morbillivirus Canine distemper virus – severe diseases involves CNS and are fatal Causes sickness of the respiratory and GI tract What is feline calicivirus?...
