PPR infection is most commonly recorded among the sheep population in India. It is generally accepted that pathology peer review (PPR) is an important procedure to verify and improve the accuracy and quality of histopathology data generated by the study pathologist in toxicological studies of xenobiotics including pharmaceuticals and agrochemicals with experimental animals. The specialist doctor who does the examination under the microscope is called a pathologist.

Below is the link to the electronic supplementary material. Asaf Berkowitz and Oran Erster contributed equally to this work. Recognition of PPR as a problem has increased in the 1990s, partly as a result of surveillance activities of the global rinderpest eradication programme (GREP), but also because of the capacity of the infection to invade disease-free countries. All the outbreaks recorded revealed no sex differences but the age of susceptibility was seen much in young ones and death was more noted in them.
