“…These include high fever up to 42°C, lesions in mouth, oral and nasal congestion, respiratory signs, and diarrhea leading to death of the animals. Similar findings were made in previous reports [9, 15, 16]. In this study it was observed that the morbidity rate was 100% while mortality rate was 31.42%.…”

Peste des petits ruminants (PPR) is a highly contagious viral disease of domestic and wild small ruminants and thus has serious socioeconomic implications. In Pakistan, during the year 2012-2013, estimated losses due to PPR were worth Rs. 31.51 billions. Close contact between infected and susceptible animals is an important route of transmission of PPR. Therefore, carrier animals play an important role in unnoticed transmission of PPR. The objective of the study was to investigate the detection of PPR virus in goats recovered from PPR. A suspected PPR outbreak was investigated and confirmed as PPR after analysing appropriate samples collected from infected animals using rRT-PCR. A longitudinal study was conducted over the period of 16 weeks to ascertain the detection of PPR virus (PPRV) in faecal samples of recovered goats. Ninety-six (96) faecal samples from each sampling were collected at 4, 8, 12, and 16 weeks after the outbreak. Faecal samples were analysed using rRT-PCR. Of 96 from each sampling a total of 46, 37, 29, and 25 samples were positive for PPR viral genome at 4, 8, 12, and 16 weeks, respectively, after recovery. Attempts were made for the isolation of PPR virus on Vero cells, but results were negative. These results indicated the detection of PPR viral RNA up to 16 weeks after infection. Therefore, these results may help in the future epidemiology of PPR virus shedding and possible role as source of silent infection for healthy animals especially when there is no history of any outbreak in nearby flock or area.

Peste des Petits Ruminants (PPR) is a highly contagious viral disease of domestic and wild small ruminants causing high morbidity and mortality (up to 100%) and thus, has serious socioeconomic implications. In Pakistan, estimated losses due to PPR during the year 2012-13 were worth Pakistan Rs. 31.51 billion. Close contact between infected and susceptible animal is an important route of transmission of PPR. Therefore, carrier animals play an important role in unnoticed transmission of the disease. Limited information is available about the persistence of PPR virus in goats. Hence, the objective of the study was to investigate the persistence of PPR virus (PPRV) in goats recovered from PPR. A suspected PPR outbreak in sub-urban area of Lahore district of the Punjab Province in Pakistan was investigated. The outbreak was confirmed as PPR after analyzing appropriate samples (nasal/ocular swabs, fecal and tissue samples) collected from the infected animals. A longitudinal study was conducted over a period of 16 weeks to ascertain the persistence of PPRV in the fecal samples of recovered goats (n=96) collected at 4, 8, 12 and 16 weeks after the outbreak. Samples were analyzed using RT-PCR. Of the 96 fecal samples, 46, 37, 29 and 7 goats remained positive for PPRV genome at 4, 8, 12 and 16 weeks after recovery, respectively. The results revealed the detection of PPRV genome in goats at 16 weeks after recovery. Therefore, it can be concluded that PPR disease has a carrier potential and goats recovered from PPR infection may act as source of carrier animals.

“…In this study no difference was found, for any of the pathogens, between herds with proximity to wildlife and those without. PPRV has long been known to cause disease in wildlife [28]. Clinical signs are yet to be described in wild ruminants in sub-Saharan Africa, but have been reported in wild ruminants in Asia and in the Middle East [67].…”

“…Wild ruminants have been shown to carry PPRV and several species can develop clinical signs of PPR [28,31,32]. Whether interaction or proximity between livestock and wildlife in general, and wild ruminants in particular, is an important risk factor for exposure to PPRV has not yet been determined.…”

Introduction: Livestock husbandry is critical for food security and poverty reduction in a low-income country like Tanzania. Infectious disease is one of the major constraints reducing the productivity in this sector. Peste des petits ruminants (PPR) is one of the most important diseases affecting small ruminants, but other infectious diseases may also be present. Objective: The objective of this study was to determine the seroprevalence and risk factors for exposure to PPR, contagious caprine pleuropneumonia (CCPP), foot-and-mouth disease (FMD), bluetongue (BT), and bovine viral diarrhoea (BVD) in sheep and goats in Tanzania. Methods: Serum samples were collected in 2014 and 2015, and analysed using enzyme-linked immunosorbent assays to detect antibodies to the five pathogens. Results and discussion: This is the first description of seroprevalence of FMD and BT among small ruminants in Tanzania. Risk factor analysis identified sex (female) (OR for 2014: PPR: 2.49, CCPP: 3.11, FMD: 2.98, BT: 12.4, OR for 2015: PPR: 14.1, CCPP: 1.10, FMD: 2.67, BT: 1.90, BVD: 4.73) and increasing age (>2 years) (OR for 2014: PPR: 14.9, CCPP: 2.34, FMD: 7.52, BT: 126, OR for 2015: PPR: 8.13, CCPP: 1.11, FMD: 2.98, BT: 7.83, BVD: 4.74) as risk factors for exposure to these diseases.
