Evaluation of the diagnostic accuracy of lateral flow devices as a tool to diagnose rabies in post-mortem animals.
Implementation of lateral flow devices (LFDs) for rabies antigen detection is expected to improve surveillance through the efficient detection of rabid animals in resource-limited settings; however, the use of LFDs for diagnosis remains controversial because some commercially available kits show low sensitivity. Therefore, we compared the diagnostic efficacy of three LFDs (ADTEC, Bionote, and Elabscience kits) paralleled with the direct fluorescent antibody test (dFAT) using fresh samples and investigated the diagnostic accuracies. To do so, we evaluated rabies-suspected samples submitted to the Regional Animal Disease Diagnostic Laboratory III, Philippines. Furthermore, we conducted real-time RT-PCR and sequencing to measure the accuracy of field laboratory diagnosis. The total number of animals submitted during this study period was 184 cases, including negative control samples. Of these, 53.9% (84 cases) were positive in the dFAT. Dogs were the most common rabies-suspected animal (n = 135). The sensitivities of the ADTEC and Bionote kits were 0.88 (74 cases) and 0.95 (80 cases), respectively. The specificity of both kits was 1.00 (100 cases). Furthermore, the sensitivity and specificity of the ADTEC kit after directly homogenizing the samples in assay buffer without dilution in phosphate-buffered saline (ADTEC kit DM) were 0.94 (79 cases) and 1.00 (100 cases), respectively. By contrast, there were no positive results using the Elabscience kit among all dFAT-positive samples. The sensitivity and specificity of LFDs make these tests highly feasible if properly used. Therefore, LFD tests can be used to strengthen the surveillance of rabies-infected animals in endemic and resource-limited settings
Combining conventional and participatory approaches to identify and prioritise management and health-related constraints to smallholder pig production in San Simon, Pampanga, Philippines
Pork is the main meat produced and consumed in the Philippines. The majority of pigs are raised by smallholders who experience a range of constraints to their pig production. This study presents the findings of the first part of an overarching project that used an Ecohealth approach and aimed to improve the production and competitiveness of the smallholder pig system in an area of the Philippines. A participatory approach was embraced, combining conventional and participatory epidemiology methods followed by a stakeholder discussion. The first aim was to identify management and health-related constraints to pig production among smallholder famers in San Simon, Pampanga, Philippines. The second aim was for the project team and stakeholders to jointly prioritise activities for the immediate future to address these constraints. Key management and health-related constraints identified included inadequate water supply to pigs, particularly lactating and gestating sows, and a range of feeding-related issues. Diarrhoea was recognised as the disease syndrome of highest priority and limited record keeping meant that farmers were unable to assess the productivity and profitability of their pig farming enterprises. Actions jointly prioritised by stakeholders and the project team were: the appointment of a project coordinator within each barangay; conduct two sets of seminars, the first covering water and nutrition and the second piglet management and diarrhoea, to be delivered by technical experts but with farmer âtrusted sourcesâ also sharing their experiences; development of easily understandable leaflets and posters covering key technical information; promotion of nipple drinkers attached to five-gallon water containers and creep boxes for piglets, and conduct of a record keeping workshop with a small group of innovative farmers to develop a useful and usable tool for record keeping. The use of multiple approaches to data-gathering enabled triangulation of study findings. Without any one of these components the understanding of the pig production system would have been less complete and it is possible that the proposed actions would not have been as well-tailored to the needs of the farmers. The participatory approach, in particular the stakeholder discussion, provided the opportunity to embrace the âdeciding togetherâ and âacting togetherâ stances of participation rather than the lower âinformation givingâ stance, thereby giving stakeholders greater ownership of the future activities of the overarching project and beyond
Improving the productivity of the smallholder swine raising in San Simon, Pampanga, Philippines using an ecohealth approach: the importance of a communication plan
Smallholder raisers dominate pig production in the Philippines but financial setbacks due to increasing costs of living affect their income and interest in pursuing the livelihood. Using a combination of EcoHealth and participatory approaches, this study aimed to develop a communication plan that will help address problems in smallholder swine raising in San Simon, Pampanga. The main problems of the stakeholders in the municipality, which can be addressed through improved communication, were determined using the data gathered from a baseline survey, interviews, focus group discussions, and observations. Smallholder swine raisers (SSR), field implementers (i.e. provincial veterinarians, municipal agricultural technicians and barangay/village livestock coordinators), and agrivet store personnel were initially identified as the initial stakeholder groups. Sub-optimal husbandry and treatment practices, non-compliance to biosecurity protocols, lack of animal records and an opportunistic trading arrangement were identified as the main problems of the SSR. Lack of coordination within the barangay and limited information, knowledge and skills of field implementers are also problems that need to be addressed. Limitations in distributing educational materials by agrivet store personnel among SSR were identified. Strategic communication objectives, appropriate communication materials and activities will be developed at the next stage of the project to help address these problems
