  • Movement and feeding habits of semi-confined domestic pig groups in a
           rural location endemic to cysticercosis

    • Abstract: Abstract Free-range pigs are in the highest risk to acquire cysticercosis in endemic rural locations, although the behavioral and physiological responses to the infection are known to vary widely between pigs. Those animals reared in semi-confinement showed a group behavior that allows us to follow the herd to assess the risks of contact with the parasite. This study is aimed to determine the movement and feeding habits of pig groups raised under semi-confinement conditions, using minimally invasive procedures, applying trajectory analysis to different herds in rural settings. Pig population and subpopulations were characterized, and their movement was evaluated in two seasons of the year, using a global positioning system (GPS). Our results indicate that pig groups are formed based on human ownership and the establishment of family bonds with each other. Each group interacts with other groups in specific sites of the village. Significant differences were found in the time and distance covered by pigs in the dry and rainy seasons (P < 0.05), and the distance travelled by different groups were found to take place in repetitive, well-defined spaces that include moving through sewage, landfills, and open defecation sites. Due to this stability, the trajectories covered by pigs could be useful as indicators of risk factors linked to the exposure of pigs to Taenia solium.
  • A transdisciplinary approach to disease ecology: Emerging coronaviruses

    • Abstract: Abstract Humankind is currently facing the effects of an unparalleled pandemic that has impacted healthcare, social, and economic systems worldwide. Numerous studies have been published since the SARS-CoV-2 outbreak began in Wuhan, China. Most have focused on virology, epidemiology, pathogenesis, and therapeutic medicine, having been centered by reactive strategies to control the pandemic. Meanwhile, publications addressing the ecological, evolutionary, and anthropogenic drivers of virus emergence, and potential strategies to prevent future outbreaks have been sparse. Here, we highlight the necessity of complementary and transdisciplinary insight and methodologies from an integrated perspective to study emergent diseases. It is paramount to situate the consistently associated factors to understand the complexity of the current pandemic. Disease ecology can examine information to recognize the causes of emergence while appraising the role of interactions among pathogens, domestic animals, wildlife, and humans, integratively. Here we draw on a variety of disciplines and perspectives, from evolutionary biology, biogeography, ecology, molecular epidemiology and integrative health, to address the emergence of coronaviruses, with particular emphasis on SARS-CoV-2. We describe the process of the surfacing of zoonotic diseases, highlighting the interactions among wildlife, domestic animals, and humans, as well as the genetic, evolutionary, ecological, and anthropogenic processes that favor coronavirus epidemics and epizootics. We discuss specific results related to corona virus investigations conducted in Mexico based on disease ecology methodologies. Finally, we describe alternative approaches for understanding and preventing future outbreaks and we suggest strategies to entice integrative and transdisciplinary research within the One Health/Ecohealth paradigm.
