How FMD vaccine is produced?

Particulary in non-European countries FMD-vaccines are prepared from virus produced in suspension cultures of a Baby-Hamster kidney (BHK) cell line. In the present author’s variant of the system, virus is produced in growing BHK cells.

What are the methods of vaccination production?

Vaccine manufacturing relies on processing a virulent parental virus in four different ways:

  • Attenuation.
  • Inactivation.
  • Fractionation.
  • Cloning.

Is FMD a live vaccine?

Live attenuated vaccines In one study, the live attenuated vaccine for FMD was demonstrated to protect vaccinated animals from developing lesions, with only one exception – one vaccinated animal developed a fever [79]. The new attenuated FMD vaccines are considered to be more stable than previous strains.

What type of virus is FMD?

FMD is caused by an Aphthovirus of the family Picornaviridae, seven strains (A, O, C, SAT1, SAT2, SAT3, and Asia1) are endemic in different countries worldwide. Each strain requires a specific vaccine to provide immunity to a vaccinated animal.

How do you treat FMD in cattle?

There is no specific treatment for FMD. In endemic countries antibiotic therapy may be used to control secondary bacterial infection of ulcers but recovery takes several weeks to months. In the UK animalsthat are confirmed to have FMD will be compulsorily slaughtered (with government compensation).

What do you mean by vaccine production?

How are vaccines produced? Vaccines are made from dead (inactivated) or modified (attenuated live) whole microbes, or from inactivated or recombinant parts of microbes that are responsible for disease (such as toxins or surface proteins).

What is FMD virus?

Foot-and-mouth disease (FMD) is a highly contagious virus disease of animals. It is one of the most serious livestock diseases. It affects cloven-hoofed animals (those with divided hoofs), including cattle, buffalo, camels, sheep, goats, deer and pigs.

Is FMD vaccine safe in pregnancy?

In conclusion, FMD vaccine increases pregnancy failure when it is administered before 45 days of gestation, an effect that was associated with hyperthermia and local adverse reaction. No effect on pregnancy failure was found when vaccination was performed after 45 days of gestation.

Why FMD is called Tiger heart disease?

The FMD virus often causes severe myocardial necrosis in neonatal and young pigs. This often leads to sudden deaths from myocardial failure. The mottled myocardial lesions sometimes are referred to as “tiger-heart” lesions and are useful in diagnosis.

What is FMD condition?

Fibromuscular dysplasia is a condition that causes narrowing (stenosis) and enlargement (aneurysm) of the medium-sized arteries in your body. Narrowed arteries can reduce blood flow and affect the function of your organs. Fibromuscular dysplasia appears most commonly in the arteries leading to the kidneys and brain.
