Specifically, in clinical medicine, histopathology refers to a biopsy or surgical sample examination by a pathologist. PPR virus isolates differ in their pathogenicity for each host, with some strains resulting in more disease in sheep than goats.

A less‐severe reduction in Ppr expression permitted progression of mammary gland development beyond the induction stage, but the nipples of these mice were dramatically smaller than those of controls, with altered epidermis and connective tissue. Discussion. Peste des petits ruminants (PPR) is an acute or subacute viral disease of goats and sheep characterized by fever, necrotic stomatitis, gastroenteritis, pneumonia, and sometimes death. In areas where peste des petits ruminants (PPR) is endemic, most rinderpest-like syndromes are more likely to be PPR. • Histopathology specimens are a vital in patient care. Peste des petits ruminants (PPR) is a highly contagious viral disease of goats and sheep. It is caused by PPR virus, a morbillivirus of the PubMed  Confirmatory tests include histopathology, polymerase chain reaction (PCR), virus isolation (VI), and virus neutralization (VN). The histopathology, IHC, and quantitative RT-PCR results from both sheep and goats also provide some insight into the disease progression of PPR in small ruminants. Reduction of Ppr expression to very low levels prevented mammary gland development. It is good practice to collect blood for serological diagnosis at all stages, but particularly later in the outbreak. Histology. Looking for online definition of PPR or what PPR stands for?

It is then processed and cut into very thin layers (called sections), stained, and examined under microscopes to characterize the details of the cells in the tissue. In PPR, papules usually contain a prominent perivascular and perifollicular inflammatory infiltrate in the superficial and mid-dermis consisting of lymphocytes, neutrophils, and plasma cells. This is likely due to variations in (PMID: 25418782), Taylor WP, Albusaidy S, Barrett T (1990) The Epidemiology of peste-des-petits-ruminants in the sultanate of Oman. The specialist doctor who does the examination under the microscope is called a pathologist. 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.

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. Since then, other attempts to reproduce the pathology associated with PPR have been performed under experimental conditions [13–16], however, results have varied considerably. In tumors that showed a pPR, 27.1% were grade 1 tumors, 27.1% were grade 2 tumors, and 2.1% were grade 3 tumors (Table 5).
