Question 1

The chewing-gum-type seizure is a common anxious symptom in canines suffering from

Accepted Answer

Canine Distemper

Answer

The 'chewing-gum' seizure, characterized by repetitive jaw movements, is a classic neurological sign associated with Canine Distemper virus infection. This symptom is often seen in the later stages of the disease when the virus affects the central nervous system. It is a distinct and severe manifestation of this highly contagious and often fatal illness.

Question 2

One of the most common clinical symptoms of the following horse diseases is abortion:

Accepted Answer

Equine viral rhino pneumonitis

Answer

Equine Viral Rhinopneumonitis (EVR), caused by Equine Herpesvirus-1 (EHV-1), is a significant cause of abortion in mares, particularly during the last trimester of pregnancy. The virus can lead to fetal death and subsequent abortion, making it a major concern in equine breeding. Other symptoms include respiratory disease and neurological issues.

Question 3

Chickens with the following illness experience immunological suppression:

Accepted Answer

IBD

Answer

Infectious Bursal Disease (IBD), also known as Gumboro disease, is a highly contagious viral disease of young chickens that primarily targets the bursa of Fabricius. This organ is crucial for B-lymphocyte development, and its damage leads to severe immunosuppression, making the birds highly susceptible to other infections and reducing vaccine efficacy.

Question 4

PPR disease causes high mortality and is more severe than

Accepted Answer

Goats

Answer

Peste des Petits Ruminants (PPR), also known as sheep and goat plague, is a highly contagious viral disease primarily affecting small ruminants. While both sheep and goats can be infected, the disease is generally more severe and causes higher mortality rates in goats compared to sheep. This difference in susceptibility is a key epidemiological characteristic of PPR.

Question 5

Bluetongue virus biological carriers:

Accepted Answer

Culicoides

Answer

Bluetongue virus (BTV) is transmitted primarily by biting midges of the genus *Culicoides*. These insects act as biological vectors, meaning the virus replicates within them before being transmitted to susceptible animals, particularly ruminants like sheep and cattle. Other insects like ticks, mosquitoes, and fleas are not the primary vectors for BTV.
