2021
Ildarabadi, Hossein | Yourdkhani, Soroush | Zakian, Amir
BACKGROUND: Peste des petitis (PPR) is a highly contagious viral disease with high incidence and mortality rate, which is endemic in the Middle East, Southwest Asia, and Africa. This disease has been causing economic losses in sheep and goat flocks in these areas. Studies have shown that environmental and host risk factors can influence the severity of PPR infection. OBJECTIVES: We conducted the present study to investigate the prevalence of PPR in small ruminants population of Garmsar city and its suburbs. Furthermore, the effect of host factors, including animal species, gender, and age, and environmental factors, such as sampling season, geographical area, and sampling location, were evaluated. METHODS: Blood samples of 180 sheep and goats were taken in spring, summer, and autumn and after centrifugation, serum samples were isolated. We measured antibody response using competitive enzyme linked immunosorbent assay (C-ELISA). RESULTS: The apparent and true prevalence of contamination in small ruminants of Garmsar and its suburbs ware 24.44 % and 23.91 %, respectively. The results revealed non significant relationships between animal species (p < /em>= 0.08), gender (p < /em>= 0.14), and age (p < /em>= 0.98) with PPR serum prevalence. Meanwhile, there was a significant relationship between season (p < /em>= 0.03), geographical area (p < /em>= 0.0004), and sampling location (p < /em>= 0.0001). In addition, the odds ratio of PPRV infection in autumn was 2.62 (95% CI: 0.06 – 6.02; p < /em>< 0.05) times more than that of other season and in the south-eastern of Garmsar, it was 6.71 (95% CI: 3.01-17.60; p < /em>< 0.05) times more than that of other geographical regions. The odds ratio of PPRV infection in the Mahmood Abad village was 63.63 (95 % CI: 12.14 – 132.93; p < /em>< 0.05) times higher than that of other villages. CONCLUSIONS: According to the obtained findings, PPR was proven to be an endemic disease in Garmsar and its suburbs and the environmental risk factors have a greater impact on the seroprevalence of disease than host risk factors. Therefore, in order to control the disease in endemic areas, further attention should be paid to environmental risk factors and minimizing the risk of epidemics through vaccination at sensitive timescales and areas before high-risk environment changes.

BACKGROUND: Peste des petits ruminants (PPR) is an acute and highly contagious viral disease of small ruminants that is characterized by high fever, ocular and nasal discharge, pneumonia, necrosis, ulceration of the mucous membranes and inflammation of the gastro-intestinal tract leading to severe diarrhea. OBJECTIVES: The aim of this study was to investigate the seroprevalence of peste des petits ruminants (PPR) virus infection in sheep and cattle in Ahvaz. METHODS: Blood samples were taken from 100 cattle and 100 sheep that were kept together from different parts of Ahvaz. Blood samples were also taken from 16 vaccinated sheep against PPR for positive control. The sera were separated by centrifuge at 3000 ×g for 10 minutes and 3 mL of serum was harvested and stored at -20 °C until determination of antibody against PPR using VN method. RESULTS: The peste des petits ruminants (PPR) antibody seroprevalence was 23% in cattle and 58% in sheep and all the sheep samples collected for control were positive for PPR antibody. CONCLUSIONS: The present study indicates serological evidence for the natural transmission of PPRV from sheep to cattle under natural conditions and provides baseline information on prevalence of PPRV antibodies in cattle and sheep population in Ahvaz.

Peste des petits ruminants (PPR) is an acute, highly contagious, OIE notifiable and economically important transboundary viral disease of sheep and goats. PPR is enzootic in India as a greater number of outbreaks have occurred in the past and now occurring regularly round the year and throughout the country. The PPR outbreaks in sheep and goats have declined in some of the Indian states Viz., Andhra Pradesh, Telangana, Karnataka, and Chhattisgarh after implementing the strategic mass vaccination campaigns. The decreased number of outbreaks, as well as changes in the disease severity patterns and distribution, might be due to the effectiveness of the vaccine, timely vaccination, and most importantly effective implementation of the vaccination strategic plan. This review is focused upon the overall understanding of the National PPR Control Programme (PPR -CP) and its strategies vaccination implantation in India for the control and eradication of PPR.

Clinical signs suggestive of peste des petits ruminants (PPR) involved herds of small ruminants, which were described elsewhere in Sudan. Peste des petits ruminants was confirmed using an Immunocapture ELISA (IC-ELISA) assay in samples of infected and dead animals in areas of outbreaks. Therefore, to update information regarding the current situation and for assessment of the serological prevalence of PPR in small ruminants mingled at Central and Western Sudan during 2018-2019, 368 sera were collected from sheep (325 sera) and goats (43 sera) with different ages and breeds. These sera included 186 sera (173 sheep and 13 goats) from White Nile State and 182 sera (152 sheep and 30 goats) from Kordofan States. Competitive ELISA demonstrated higher prevalence of PPRV antibodies of 88.9%, 90.7% and 88.6% in both sheep and goats, goats, and sheep sera, respectively. Moreover, 100%, 94.7% and 78.5% seroprevalence values were demonstrated in South Kordofan, North Kordofan and White Nile States. The higher seroprevalence values detected in sera of unvaccinated sheep and goats indicated the wide exposure of these animals to PPRV and presence of protection following PPR viral infection. The findings of the study indicated that PPR is endemic in the surveyed areas of Sudan. CONTRIBUTION: The study will contribute effectively to the global eradication programme of PPR organised by the World Organization for Animal Health (WOAH, formerly OIE) and Food and Agriculture Organization (FAO). To completely eliminate PPR from Sudan by 2030, local efforts should be directed towards effectively and wholly vaccinating small ruminants using PPRV vaccine especially in routes of seasonal animal's movement and shared grazing areas.

In Bangladesh, veterinarians often claim to reduce the mortality of natural peste des petits ruminants (PPR) outbreaks with the help of supportive fluid and electrolyte therapy. Information on haematological and biochemical parameters of PPR-infected goats, which is often altered because of associated tissue damages, is necessary to formulate the appropriate supportive therapy. This study determined the haematological and serum biochemical parameters of Black Bengal goats naturally infected with PPR virus. Blood and serum samples from 13 PPR-affected Black Bengal goats from 13 field outbreaks and 5 healthy goats were collected and analysed by routine haematological and biochemical examination. Haematological analysis of PRR-affected goats showed severe anaemia characterised by significant decrease in the values of haemoglobin, total erythrocyte counts (TECs) and packed cell volume (PCV). On the contrary, PPR-affected goats showed marked leucocytosis with absolute increase in lymphocytes and neutrophils counts compared to the healthy goats. Biochemical analysis revealed significant decrease in total protein and albumin level and increased creatine kinase, aspartate transaminase and alanine transaminase that mirrored the gross and histopathological changes in the PPR-affected goats. Significant increase in the values of sodium and chloride ions was found in the sera of PPR-infected goats. Peste des petits ruminants virus altered the haematological and serum biochemical parameters of the infected goats. Antidiarrheal agents with aqua solution together with other drugs to support liver and kidney function could help improve therapy of PPR-infected goats.

Eight outbreaks of peste des petits ruminants in sheep and goats were reported in White Nile State, Sudan, between 2008 and 2009. A mortality rate of 4.2% was reported across the different outbreaks. Clinically the disease was characterised by high fever, ocular and nasal discharge, pneumonia, ulceration of the mucous membranes, diarrhoea and death. The postmortem findings included necrotic lesions in the mouth and gastrointestinal tract, and swollen, oedematous lymph nodes associated with the lungs and intestine. Of the 209 serum samples tested by competitive enzyme-linked immunosorbent assay, 113 (54%) were found positive. Peste des petits ruminants virus was confirmed in tissues, nasal swabs and blood samples by immunocapture enzyme-linked immunosorbent assay, reverse-transcription polymerase chain reaction and isolation of the virus in culture of lamb testicle cells.

Ibrahim M. Alzuheir
Objective: This study aims to analyze and map existing research literature on peste des petits ruminants virus (PPRV) to identify research hotspots, knowledge gaps, and future directions. PPRV causes peste des petits ruminants (PPRs) disease, leading to significant impacts on small ruminants through high mortality rates and trade limitations. Eradication programs are led by the Food and Agriculture Organization and the World Organization for Animal Health. Materials and Methods: Data were obtained from the Scopus database using keywords related to PPRV and PPR, covering the period from 1990 to 2023. Validation methods were employed to verify the search strategy's accuracy. Data analysis focused on identifying temporal evolution, geographical distribution, key contributors, sources, research hotspots, and gaps, which were visualized using maps. Results: The study identified 478 research documents from 1,834 authors, with most being research articles (91.0%). A significant increase in publications was observed from 1990 to 2023, peaking in 2019 and 2021. India led with 112 articles, followed by the UK (79) and China (71). Top research institutions included the Indian Veterinary Research Institute and the Pirbright Institute in the UK. Major contributors like S. Parida and V. Balamurugan formed dense international col¬laboration networks. Key journals included "Transboundary and Emerging Diseases" and "Journal of Virological Methods." Conclusion: This study reveals an increased global scientific production on PPRV, driven by international collaboration. However, research gaps remain, particularly from North African and Middle Eastern countries. Priorities include vaccine development, vaccination campaigns, veteri¬nary capacity building, and enhanced reverse transcription polymerase chain reaction implemen¬tation. Insights from ths study can guide policymakers, funders, and researchers in prioritizing resources and strategies to eradicate PPRV, ensuring sustainable livestock health and economic stability.

Objective: The objective of this study was to determine the prevalence, geographical distribution, and main risk factors for peste des petits ruminants (PPR) in the Republic of Chad. Materials and methods: A total of 3,546 sera collected from unvaccinated small ruminants including 1,699 goats and 1,847 sheep in 19 of the 23 regions in Chad were randomly sampled. The competitive enzyme-linked immunosorbent assay technics were used for serological analysis. Results: The overall seroprevalence at the individual level was 52.9%±1.6% (48.9% for goats and 56.2% for sheep). Seroprevalence observed in the Chari Baguirmi, Ouaddaï, and NDjamena regions was significantly higher than those in the other regions. Transhumant herds are the most exposed than the sedentary ones. Older animals were more affected than the young ones. Kababich sheep are the most affected than other breeds. Conclusion: This study has shown that the PPR virus is circulating in the Republic of Chad. In view of the results obtained, the disease is enzootic in the country. Epidemiological information obtained including seroprevalence rate, risk factors (sex, breed, age, and mode of rearing), and geographical distribution will help to define an appropriate strategy for PPR control in the Republic of Chad.

The seroprevalence and risk factors of Peste des Petits Ruminants (PPR) were determined in unvaccinated sheep and goats in Sudan. A total of 480 sera samples were collected from the sheep (n=261) and goats (n=219) of Sennar, Gedarif, River Nile, and North Kordofan states during May, June, and October 2012 and February 2013, respectively. The sera were tested for the presence of antibodies against PPR using competitive Enzyme Linked Immunosorbent Assay. The overall seroprevalence of PPR was recorded as 45.6% (n=219/480); whereas, 57.2% in Sennar, 46.2% in Gedarif, 34.9% in River Nile and 39.8% in North Kordofan. A total of 14 risk factors were investigated using structured questionnaire, of which 9 were found to be associated with PPR seroprevalence (p≤0.05). Among the localities, Abozabad located in North Kordofan had the highest prevalence (91.7%) of PPR followed by Barbar in River Nile. PPR seroprevalence was higher in pastoralists, animals housed in scarp fences, females, and Kwahla sheep. In addition, PPR was higher in the states that had high rainfall and wind-speed. The associated 9 factors were further analyzed multivariably by logistic regression, and finally 5 of them (states, localities, husbandry system, gender, and age) were found to be associated with PPR seroprevalence (p≤0.05).
