This study evaluates the tissue tropism and pathogenesis of PPR following experimental infection of sheep and goats using a quantitative time-course study. This study evaluates the tissue tropism and pathogenesis of PPR following experimental infection of goats using a lineage IV virus, the most dominant in the world originated from Asia. Peste des petits ruminants (PPR) is a viral disease of major economic importance on small ruminants. It is also known that goats are more sensitive than sheep especially for North African breed as described by many authors [19, 29, 30]. The pathogenesis associated with PPR virus (PPRV) has largely been assumed from that established for closely related viruses such as rinderpest virus (RPV), measles virus and … Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level.It is a specialized field of study in virology.. Pathogenesis is a qualitative description of the process by which an initial infection causes disease. doi: 10.1016/j.smallrumres.2016.02.018. Infected cells and supernatant were harvested and frozen at − 80 °C for subsequent experiments. A future significance of PPR can be realized by the phrase stated by the editors, “If rinderpest becomes a disease of the past, PPR is certainly a disease of the future.” ... and a brief overview of the pathogenesis and eradication of measles virus. Emikpe BO, Akpavie SO. Animals were tested negative for PPRV specific antibody by virus neutralization test (VNT) and ELISA using the blocking enzyme-linked immunosorbent assay (bELISA). Goats were fed a complete balanced diet and water ad libitum and housed in animal boxes (Biosecurity level 3 containment) at MCI Santé Animale. Results presented are average temperature of four goats infected with cell virus suspension and infectious mashed tissue, signs and lesions observed on goats. However, in this study local goat breed showed similar sensitivity to PPRV as Alpine goats and could be used for challenge model. Nasal discharge (a), hypertrophy of mesenteric nodes (b) and lung congestion (c) observed on Peste des Petits Ruminants infected goat. A reliable and reproducible experimental challenge model for peste des petits ruminants virus. The incursion, persistence and spread of peste des petits ruminants in Tanzania: epidemiological patterns and predictions. Signs, lesions, mortality and viral charge are clearly expressed in group II (infected with tissue mixture) comparatively to group I (infected by cell suspension). For goats 1 and 2 of group I we observed congestion and hepatization lung, hypertrophy of mesenteric and pulmonary nodes, and one goat presented mild inflammation of intestine (Fig. PPR is an acute infectious viral disease of small ruminants, characterized by fever , oculo-nasal discharge, erosive stomatitis, conjunctivitis, gastroenteritis. To appreciate the severity of the infection we considered the five criteria listed in the results chapter. A real time RT-PCR assay for the specific detection of Peste des petits ruminants virus.

Hammouchi M, Loutfi C, Sebbar G, Touil N, Chaffai N, Batten C, et al. 2016;142:16–21. Similar signs has been also observed by several authors confirming that PPR is dominated by pulmonary signs [20, 31, 32]. 2011;171:401–4. in our study, the use of infected tissue is much more efficient than the cell culture suspension virus probably because of virus adaptation on cells. One goat presented a mild dyspnea and alimentation decrease in the last days. Rajak KK, Sreenivasa BP, Hosamani M, Singh RP, Singh SK, Singh RK, et al. PPR is stand for Pestis des pestitis ruminants. Front Vet Sci. The clinical signs were observed and goats were euthanized at predetermined clinical score level for post-mortem examinations and PPRV detection by RT-PCR. bELISA was developed, tested and validated by the Pan African Veterinary Vaccine Centre of the African Union (AU-PANVAC) [36]. Used route of infection is the most appropriate since IN spray reproduce the natural infection conditions and the IV injection allow to secure a minimal quantity of the virus administered. Background: Peste des petits ruminants (PPR) is a viral disease which primarily affects small ruminants, causing significant economic losses for the livestock industry in developing countries. Peste des Petits Ruminant (PPR) is an important transboundary, OIE-listed contagious viral disease of primarily sheep and goats caused by the PPR virus (PPRV), which belongs to the genus Morbillivirus of the family Paramyxoviridae. PCR analysis of collected swabs suggest that animals became contagious from D3 through lacrimal secretion then nasal secretion and faeces from D6. Vet Microbiol. Nanda Y, Chatterjee A, Purohit A, Diallo A, Innui K, Sharma R, et al. After washing the wells of the plates with PBS, 100 μl of an Monoclonal antibody C4F3 & conjugate anti-mouse was added to fix the remaining free epitopes. These signs were scored as described in Table 3. Evidence that circulating lymphocytes act as vehicles or viraemia in measles. 1996;51:207–16. The current understanding of PPRV pathology has been assumed from the closely related rinderpest virus and other morbillivirus infections [23]. PPRV genome was highly detected in swabs and tissues with clinical signs dominated by pulmonary attack and digestive symptoms secondary. The blood samples were directly used for RNA extraction. Goats are usually known to be more susceptible to the disease. The experimental PPRV-infection model using the cell virus suspension is suitable for vaccine evaluation as a standard model. Acta Vet Scand. One goat presented an important dyspnea, depressive comportment and alimentation decrease in the last days (Table 1). Increasing body temperature was reported in group I at D5 pi with a maximum at D7pi while in group II hyperthermia started at D2 at to D7 pi. The cell virus suspension had a titer of 6.2 logTCID50/ml. 2020 Aug;13(8):1661-1666. doi: 10.14202/vetworld.2020.1661-1666. eCollection 2014.
