An appropriate age for the first rabies immunization is:
The minimum number of organisms necessary to cause infection reveals
The amount of organism required to initiate an infection is an indication of infectivity. Infectivity refers to the ability of a pathogen to establish an infection in a susceptible host. It is often measured by the minimum infectious dose, which is the smallest amount of the pathogen needed to cause infection in a given percentage of exposed individuals.
Bluetongue virus biological carriers:
The biological vectors of the Bluetongue virus are certain species of biting midges in the Culicoides genus. These tiny insects, commonly referred to as Culicoides biting midges or no-see-ums, play a crucial role in the transmission of the Bluetongue virus.
The chewing-gum-type seizure is a common anxious symptom in canines suffering from
The chewing gum type of seizure is a classical nervous sign seen in dogs affected by Canine Distemper. Canine Distemper is a viral disease that affects dogs and is caused by the canine distemper virus (CDV). It can result in various neurological signs, including seizures.
During a chewing gum seizure, affected dogs exhibit repetitive chewing movements, similar to chewing gum. This type of seizure is often accompanied by other neurological symptoms such as muscle twitching, tremors, and convulsions. These seizures occur due to the viral infection affecting the central nervous system and causing abnormal electrical activity in the brain.
PPR disease causes high mortality and is more severe than
PPR (Peste des Petits Ruminants) is a highly contagious viral disease that primarily affects small ruminants such as goats and sheep. Among these two species, goats tend to experience more severe symptoms and higher mortality rates compared to sheep when infected with PPR.
One of the most common clinical symptoms of the following horse diseases is abortion:
Equine viral rhino pneumonitis (EVR), also known as equine herpesvirus (EHV) infection, does not typically present abortion as one of its predominant clinical signs.
Chickens with the following illness experience immunological suppression:
IBD stands for Infectious Bursal Disease, which is a highly contagious viral disease that primarily affects young chickens. While IBD primarily affects the bursa of Fabricius (an organ involved in the development of the chicken's immune system), it does not typically cause immune suppression in affected chickens. In fact, IBD primarily targets and destroys B lymphocytes, leading to immunosuppression.
