Comprehensive Study Reveals Prevalence and Distribution of Amphistomes in African Wild Ruminants

New Study Unveils Hidden Threats: Amphistome Infections in African Wild Ruminants!

A recent study by Sibula et al (2024) titled “Prevalence and geographical distribution of amphistomes of African wild ruminants: A scoping review” published in the International Journal for Parasitology: Parasites and Wildlife, shows that amphistome infections in wild ruminants were reported in 23 out of 54 African countries, with 38 amphistome species identified across 39 wild ruminant species.

Amphistome infections in wild ruminants are prevalent in 23 African countries, with 38 species identified, primarily involving the Carmyerius and Calicophoron genera.– Sibula, et al 2024

The article examines the prevalence and geographical distribution of amphistomes, commonly known as rumen flukes, in wild ruminants across Africa. It highlights that infections have been reported in 23 of the 54 African countries. A comprehensive survey identified 38 amphistome species from 11 different genera. Among these, the genus Carmyerius boasts the highest number of species, while species from the genus Calicophoron are noted for their extensive distribution across the continent. The study emphasizes the critical role of freshwater snails as intermediate hosts in the lifecycle of amphistomes. Specifically, snail species from the family Planorbidae are identified as the predominant hosts facilitating the transmission of these parasites. This relationship underscores the importance of understanding the ecology and distribution of these snail species to manage and control amphistome infections effectively. The authors advocate for more in-depth studies to accurately identify the intermediate snail hosts and amphistome species. They suggest employing both morphological and molecular techniques for precise identification. Additionally, they call for an assessment of the impact of amphistomosis (infection by amphistomes) on wildlife and mixed farming systems in Africa. This would provide valuable insights into the burden of the disease, informing better management and control strategies to mitigate its effects on livestock and wildlife health.

How the study was conducted

The article aimed to answer specific questions regarding the prevalence and distribution of amphistomes in wild ruminants across Africa, following the methodological framework established by Arkey and O’Malley. The research involved comprehensive searches of electronic databases, including PubMed, JSTOR, and Google Scholar, utilizing Boolean operators and specific search terms. Additionally, reference lists of relevant publications were examined to identify further pertinent studies. The inclusion criteria for the articles were as follows: field or case studies reporting on amphistomes in wild ruminants in Africa, published between 1900 and 2022, and available in English, French, or Afrikaans. From the selected articles, data were extracted and tabulated, encompassing information about the authors, geographic regions, host species, prevalence rates, and predilection sites of the amphistomes..

What the authors found

The authors found that amphistome infections in wild ruminants were reported in 23 out of 54 African countries, with 38 amphistome species identified across 39 wild ruminant species. The genus Carmyerius had the highest number of species, while Calicophoron species were the most widely distributed. The authors also found that the common mixed infections were between amphistomes of the same or different genera, and co-infections with other trematodes like Fasciola gigantica were noted.

Why does this matter?

Ecological Impact: Amphistomes can have significant ecological impacts on wild ruminants. By identifying the prevalence and distribution of these parasites, researchers can better understand their effects on host health, population dynamics, and ecosystem balance.
Livestock Health: Amphistomes can also infect domestic livestock, affecting their productivity and well-being. Insights from this study can inform livestock management practices and disease control strategies.
Conservation: Wildlife conservation efforts rely on accurate data about parasite prevalence. Knowing which species are affected and where they occur helps conservationists make informed decisions to protect vulnerable populations.
One Health Approach: Understanding amphistome infections in both wild and domestic animals contributes to the One Health approach, which recognizes the interconnectedness of human, animal, and environmental health.

What the authors recommended

  • The authors recommend conducting additional studies to confirm the identity of snail intermediate hosts and amphistome species. This can be achieved through both morphological and molecular techniques.
  • There is a need to assess the burden of amphistomosis in wildlife and mixed farming systems across Africa. Understanding the prevalence and impact of these parasites is essential for effective disease management.
  • The authors suggest that researchers should adopt a holistic approach that considers both wild ruminants and domestic livestock. By studying amphistomes in various contexts, we can develop comprehensive strategies for parasite control.

In conclusion, the study by Sibula et al. sheds light on the significant prevalence and geographical distribution of amphistome infections in African wild ruminants, revealing the intricate relationship between these parasites and their intermediate snail hosts. By highlighting the need for precise identification techniques and further research into the impact of amphistomosis on both wildlife and livestock, the authors underscore the importance of a comprehensive approach to parasite management. This research not only contributes to the understanding of ecological and health impacts but also supports the development of effective conservation and livestock management strategies, ultimately promoting a balanced and healthy ecosystem.
