Participatory epidemiology of endemic diseases in West African cattle - Ethnoveterinary and bioveterinary knowledge in Fulani disease control

Sero-prevalence of contagious bovine pleuropneumonia in dryland of Borana, southern Oromia, Ethiopia

Ethiopia is one of the largest African countries where livestock farming represent a relevant resource for the economy and the livelihood of the population. Contagious bovine pleuropneumonia (CBPP) is among the transboundaries animal disease that is hindering cattle farming in Ethiopia. Due to the limited resources of veterinary services, disease control and surveillance is discontinuous and occasional field investigations of target areas contribute to depict disease spreading in the country. The study was conducted to determine the seroprevalence, at herd and animal level, and identify the risk factors involved in CBPP diffusion and persistence in the Borana pastoral zone. A total of 498 serum samples were collected from 120 cattle herds and tested using competitive Enzyme-Linked Immunosorbent Assay (c-ELISA). Of 120 herds sampled, 37 (30.83%; (95% CI = 22.73-39.91%) were tested positive to CBPP antibody. Out of 498 sera samples tested 46 (9.24%; 95% CI = 6.84-12.13%) were positive. The highest prevalence was observed in Teltele (12/95; 12.90%; 95% CI = 6.7-21%) followed by Yabello (12/104; 11.54%; 95% CI = 6.1-19.3%) and Arero (10/91; 10.99%; 95% CI = 95% CI = 5.4-19.3%), whereas the lowest prevalence was observed in Gomole (5/101; 6.42%; 95% CI = 1.6-11.2%) and Dubluk (7/109; 4.95%; 95% CI = 2.6-12.8%) districts and statistically not significant (p > 0.05). Results of multivariate logistic regression analysis revealed that, age, herd movement and herd size of the animals had statistically significant effect on sero-positivity to CBPP (p < 0.05). Sex, season and body condition were not significantly (p > 0.05) associated with the occurrence of CBPP. The study confirms that CBPP is persistent in the territory and remain as a major problem that affects health and productivity of cattle. Therefore, awareness creation to the pastoralists in the study area about the effect of CBPP and designing appropriate control methods has a paramount importance to improve the health and productivity of cattle production in the area.

Quantitative ethnoveterinary study on plant resource utilization by indigenous communities in high-altitude regions

For millennia, ethnic knowledge has been intricately tied to local biodiversity and woven into the fabric of rural communities. Growing scientific evidence suggests that merging ethnic knowledge with new scientific findings can lead to socially acceptable and environmentally friendly approaches essential for the long-term prosperity of local communities. In the high-altitude region, where livestock raising is a key income source, and plant-based utilization for ethno-veterinary practices is widely practiced. In this context, this study was conducted with the aim of documenting the ethno-veterinary use of plant resources in different bio-geographical regions of Jammu and Kashmir's Himalayas (J & KH). Semi-structured interviews and group discussions were used to collect information. Principal component analysis (PCA) and Pearson correlation were conducted to analyze the data. We documented 148 species from 53 families that locals used for various purposes: medicine, fodder, tonic, antidote, magic, and also used to protect themselves from ectoparasite such as Pediculus humanus capitis by the local inhabitants. There were significant differences in the relative usage of plant resources across the three biogeographic regions. Comparatively, the highest number (41%) of plant species were used for ethnoveterinary in the Jammu region, while the lowest number (28%) of species were used in Kashmir. Across the regions, Kashmir and Jammu had the highest level of species similarity (17%), while Jammu and Ladakh had the lowest (1%). A cross-regional assessment of plant resources revealed that 18% of plants were shared among the regions. The reported use of Amaranthus blitum, Morus alba, Ficus palmata, Vitex negundo, Juniperus semiglobosa, Ulmus wallichiana, and Rumex nepalensis are novel for the ethno-veterinary uses of this part of the Himalayan region. The various dry unique traditional fodder preparations (gaaslov, gass khor, pan baath, kaandbaath, Lovgooad, Karb, and Phungma) from plant resources are reported for the first time from the Himalayan region and can be ascribed to the novelty of this study. Plant resources were not only a source of fodder and medicine but also presented themselves as an opportunity for livelihood generation. Therefore, our findings bridge the knowledge gap by documenting key ethnoveterinary applications of native plant species from the study region that are used to cure livestock diseases and disorders by the mountain inhabitants.

Qualitative Research for One Health: From Methodological Principles to Impactful Applications

The One Health concept has inspired a rich vein of applied research and scholarly reflection over the past decade, yet with little influence from qualitative methodologists. With this overview, we describe the underpinning assumptions, purposes, and potential pitfalls of data collection techniques and methods of data analysis in key qualitative research methodologies. Our aim is to enhance One Health collaborations involving qualitative researchers, veterinary epidemiologists, and veterinary economists. There exist several distinct traditions of qualitative research, from which we draw selectively for illustrative purposes. Notwithstanding important distinctions, we emphasize commonalities and the potential for collaborative impact. The most important commonality is a shared focus on contextualizing human behavior and experience–culturally, economically, historically, and socially. We demonstrate that in-depth attention to context can assist veterinary economists and epidemiologists in drawing lessons from the implementation of policies and programs. In other words, qualitative researchers can assist One Health teams in distilling insights from “success stories,” but also from adverse events and unintended consequences. As a result, qualitative researchers can contribute to One Health research and policy discussions by formulating more accurate and contextually-relevant parameters for future quantitative studies. When performed well, qualitative methodologies can help veterinary economists and epidemiologists to develop impactful research questions, to create more accurate and contextually-relevant parameters for quantitative studies, and to develop policy recommendations and interventions that are attuned to the political and socio-cultural context of their implementation. In sketching out the properties and features of influential methodologies, we underscore the value of working with seasoned qualitative researchers to incorporate questions about “what,” “how,” and “why” in mixed-methods research designs.
