Demystifying and Demonstrating the Value of a One Health Approach to Parasitological Challenges.

The One Health approach recognizes the interconnectedness of human, animal, and ecosystem health and encourages collaboration between diverse disciplines to address complex health problems. In this paper, 3 academics, with diverse training, experience and backgrounds who each work on different pathogenic parasites, will share their stories of tackling parasitic challenges by applying a One Health approach. The pathogenic parasites to be discussed include the helminth Taenia solium and protozoans Giardia, Theileria, Babesia, Neospora and Toxoplasma species. The 3 narratives focus on research and clinical case-based challenges and illustrate where collaboration between human, animal, and environmental health scientists either has or could lead to improved control of human and animal health as well as important research discoveries. The need for better evaluation of interventions and scientific evidence to support changes in clinical practice and encourage enhanced collaboration between human and veterinary clinicians, as well as new governmental policies to improve public and wildlife health, are described. The need for a range of evidence-based metrics to monitor the success and impact of the One Health approach to veterinary parasitology is also discussed.

Assessment of a novel method for teaching veterinary parasitology.

A student-centered innovative method of teaching veterinary parasitology was launched and evaluated at the Ross University School of Veterinary Medicine (RUSVM) in St. Kitts, where Parasitology is a required course for second-semester veterinary students. A novel method, named Iron Parasitology, compared lecturer-centered teaching with student-centered teaching and assessed the retention of parasitology knowledge of students in their second semester and again when they reached their seventh semester. Members of five consecutive classes chose to participate in Iron Parasitology with the opportunity to earn an additional 10 points toward their final grade by demonstrating their knowledge, communication skills, clarity of message, and creativity in the Iron Parasitology exercise. The participants and nonparticipants were assessed using seven parameters. The initial short-term study parameters used to evaluate lecturer- versus student-centered teaching were age, gender, final Parasitology course grade without Iron Parasitology, RUSVM overall grade point average (GPA), RUSVM second-semester GPA, overall GPA before RUSVM, and prerequisite GPA before RUSVM. The long-term reassessment study assessed retention of parasitology knowledge in members of the seventh-semester class who had Iron Parasitology as a tool in their second semester. These students were invited to complete a parasitology final examination during their seventh semester. There were no statistically significant differences for the parameters measured in the initial study. In addition, Iron Parasitology did not have an effect on the retention scores in the reassessment study.

Towards the implementation of the "basket of options" approach to helminth parasite control of livestock: emphasis on the tropics/subtropics.

The virtual reliance on anthelmintic drugs alone to control internal parasites of livestock is inappropriate and ultimately unsustainable. In the tropics and subtropics, widespread and high levels of anthelmintic resistance, particularly in nematode parasites of small ruminants, is rife. But more to the point, many farmers in these regions of the world are resource poor and cannot afford, or are reluctant to purchase drugs that may also be of dubious quality. As it is with any intervention, the benefits must outweigh the costs. This is not only in terms of conventional parameters such as reduced mortality and increasing productivity (meat, milk, fibre and traction power) of livestock, but also within the broad framework of helminths of veterinary/human importance, the aim should be a positive impact on reducing the threat of helminth zoonoses. However, understanding the issues involved and education of the end-users (farmers) is of fundamental importance, before any internal parasite control program should be promoted. Within the above context, we provide examples of how the "basket of options" approach could be adopted for the control of three quite disparate helminth problems in the tropics and subtropics, viz.: strongyle nematode infections of donkeys, the Taenia solium cysticercosis/taeniosis problem of pig and man and Haemonchus contortus infections in small ruminants. The "best practice" approaches can be defined as those "basket of options" that are practical, affordable, available and appropriate, whether to the commercial producer, or to the resource-poor farmer. Constraints that may restrict applying such options are accessibility to, and affordability of, suitable remedies and above all, the availability of information needed to make informed decisions in this regard.
