Peste des petits ruminants (PPR) is an important cause of mortality and production loss among sheep goats in the developing world. Despite control efforts a number countries, it has continued to spread across Africa Asia, placing increasing burden on livelihoods livestock keepers veterinary resources affected countries. Given similarities between PPR rinderpest, lessons learned from successful global eradication seems appealing, both eliminating disease improving poor We conducted...
To capture lessons from the 2007 Rift Valley fever (RVF) outbreak, epidemiological studies were carried out in Kenya and Tanzania. Somali pastoralists proved to be adept at recognizing symptoms of RVF risk factors such as heavy rainfall mosquito swarms. Sandik, which means "bloody nose," was used by Somalis denote disease consistent with RVF. reported that sandik previously seen 1997/98, period last epidemic. Pastoralists communicated valuable information for surveillance early warning...
Growing evidence suggests that multiple wildlife species can be infected with peste des petits ruminants virus (PPRV), important consequences for the potential maintenance of PPRV in communities susceptible hosts, and threat may pose to conservation populations resilience ecosystems. Significant knowledge gaps epidemiology across ruminant community (wildlife domestic), understanding infection other atypical host groups (e.g., camelidae, suidae, bovinae) hinder our ability apply necessary...
Peste des petits ruminants (PPR) is a highly infectious disease of sheep and goats that caused by PPR virus, member the genus Morbillivirus includes viruses cause rinderpest (RP) in cattle. RP was first animal to be globally eradicated 2011 only second disease, after smallpox, have ever been eradicated. one principal constraints small ruminant production Africa, Asia, Middle East. The epidemiology as well technologies available for their diagnosis control are similar. conditions favored...
Abstract Pastoralists in sub-Saharan Africa have limited access to public services due their mobile lifestyle, economic and political marginalization, the health infrastructure that is common arid semi-arid lands (ASALs) where they primarily reside. This often results poor outcomes, including increased rates of maternal, neonatal, under-5 mortality. One Health approaches integrate human animal service delivery can help improve pastoralists’ through vaccine coverage improved services. Kenya...
In 1994, rinderpest virus of African lineage 2 was detected in East Africa after an apparent absence more than 30 years. 1996, a disease search, based on participatory epidemiological techniques supplemented by serological and virological analyses, undertaken southern Somalia north-eastern Kenya to collate past current information about rinderpest-compatible events, test the hypothesis that persists populations transhumant cattle Somali ethnic areas. The findings Afmadu Lower Juba led search...
Contagious bovine pleuropneumonia (CBPP) caused by Mycoplasma mycoides subsp. (Mmm) is an economically very important cattle disease in sub-Saharan Africa. CBPP impacts animal health and poverty of livestock-dependent people through decreased productivity, reduced food supply, the cost control measures. a barrier to trade many African countries this reduces value livestock income chain stakeholders. The presence also poses constant threat CBPP-free creates costs terms measures necessary...
The research objective was to develop a thermostable vaccine against peste des petits ruminants (PPR), morbilliviral disease of small targeted for eradication that is major constraint on the livelihoods rural poor throughout much Africa and Asia. Although existing PPR vaccines provide life-long immunity, they require continuous refrigeration. This limits their utility in developing countries. Methods lyophilization related morbillivirus, rinderpest (RP), resulted could be used field up...
A repository of domestic animal sera collected in Niger between 1984 and 1988 was assayed for antibody against two zoonotic hemorrhagic fever viruses known to be present the West African Sahel. total 2,540 serum samples from 2,324 cattle, sheep, goats, camels were tested by an IgG-specific enzyme-linked immunosorbent assay (ELISA) 80% plaque reduction neutralization test (PRNT80) Rift Valley (RVF) virus antibody. Of RVF-specific IgG antibody, 1,676 goats examined IgM ELISA. subset 2,263...
Participatory surveillance (PS) is the application of participatory rural appraisal methods to collection epidemiological information inform decision-making and action. It was applied in Africa Asia as part emergency programs address H5N1 highly pathogenic avian influenza (HPAI) pandemic. The approach resulted markedly increased case detection countries experiencing HPAI, a better understanding situation. Where HPAI absent PS implemented, method did not result false positives contributed...
Ten goats were inoculated with peste des petits ruminants virus, a paramyxovirus closely related to rinderpest virus. All developed severe clinical disease, 8/10 having coughing or dyspnea as prominent signs. In addition, all of the had stomatitis and diarrhea. Histopathologic immunohistochemical studies done only on respiratory tracts. Pathologic changes ranged from mild multifocal bronchiolitis bronchitis bronchointerstitial pneumonia. Lesions more in anteroventral than caudal lobes. The...
This paper describes an assessment of the patterns peste des petits ruminants virus circulation in Karamoja subregion Uganda conducted to identify communities that maintain and inform development a targeted vaccination strategy. Participatory epidemiological methods were used develop operational hypothesis for PPR was subsequently validated through outbreak investigation genomics. The participatory included risk mapping with livestock owners, community animal health workers veterinarians...
