What is PPR and explain the structure of PPR?
Pentatricopeptide repeat (PPR) proteins are a large family of modular RNA-binding proteins which mediate several aspects of gene expression primarily in organelles but also in the nucleus. These proteins facilitate processing, splicing, editing, stability and translation of RNAs.
What is PPR in biology?
Introduction. Pentatricopeptide repeat (PPR) proteins compose a family of RNA binding proteins specific to eukaryotes and mostly involved in gene expression processes in organelles. PPR proteins are particularly numerous in land plants with up to 450 representatives in Arabidopsis thaliana.
What is the function of PPR?
PPR proteins form a huge family in flowering plants and are involved in RNA maturation in plastids and mitochondria. These proteins are sequence-specific RNA-binding proteins that recruit the machinery of RNA processing.
What is PPR vaccine?
Vaccine for Plague (Peste des petits ruminants-PPR): A Disease of Small Ruminants. The PPR is most important infectious disease of small ruminants and is known as sheep and goat plague. The disease was reported in India in 1989 from Tamil Nadu. It is now prevalent in all the parts of the country.
How is PPR vaccine administered?
Dosage & Administration This vaccine should be administered with a dose of 1 ml by subcutaneous injection at mid neck region. Use precautions including application on clean dry skin, use sterile needles and syringes for every administration.
Is PPR vaccine safe for pregnancy?
The vaccine has a shelf life of more than one year at 4°C and provides immunity for three years. The vaccine is safe, potent and acceptable for use even during pregnancy.
What is PPR treatment?
PPR like other viral diseases of have no specific treatment for PPR, however mortality may be decreased by using drugs that control the bacterial complications (Taylor et al., 1984). Also, combined drug therapy can save the animal in field condition (Richrd and Adams, 1996).
What is PPR disease?
Peste des Petits Ruminants (PPR), also known as sheep and goat plague, is a highly contagious animal disease affecting domestic and wild small ruminants. It is caused by a virus belonging to the genus Morbillivirus, family Paramixoviridae.
What is the full form of PPR vaccine?
What is PPR vaccination?
Definition:- It is live attenuated freeze-dried vaccine prepared by growing Peste des petits. ruminant (PPR) virus (Sungri strain) in Vero cell culture. Use:- This vaccine is used to protect sheep & goat against PPR disease.
What is the symptoms of PPR?
The symptoms of PPR are very similar to those of rinderpest: fever, anorexia, depression, nasal and ocular discharges, difficult respiration, necrotic lesions on gum, lips and tongue resulting in salivation, erosions on the nasal mucosa and finally diarrhoea.
