Special Issue Information

Dear Colleagues,

Parasites are a group of eukaryotic pathogens that includes protozoa, helminths and arthropods, which develop over a partial or a complete life cycle in their host organisms. Parasites infect hundreds of millions of people and animals, and lead to significant mortality, in addition to causing devastating social and economic consequences, especially in tropical and subtropical areas worldwide. In this topic, we aim to collect manuscripts focusing on the epidemiology of parasitic diseases in husbandry animals together with the relevant antiparasitic treatment strategies.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Areas of interest could include, but are not limited to, the following:
  • Epidemiology of parasitic diseases in husbandry animals.
  • Novel methods and strategies for the early detection of parasites.
  • Pathogenic characteristics and metabolic mechanism of parasites.
  • Novel agents for parasite treatment.

We look forward to receiving your contributions.

Piceatannol Induces Mitochondrial Dysfunction in Toxoplasma gondii
by Zhenhe Liu, Haolong Qiu, Yucong Jiang, Yuxi Mo, Linlin Lu, Yan Wang, Dandan Hu and Xingju Song

Abstract
Toxoplasma gondii, an obligate intracellular protozoan parasite infecting nucleated cells of warm-blooded vertebrates, causes severe complications in immunocompromised hosts. Current therapies remain limited by suboptimal efficacy and toxicity, necessitating novel anti-toxoplasmic agents.

Toxoplasma gondii, an obligate intracellular protozoan parasite infecting nucleated cells of warm-blooded vertebrates, causes severe complications in immunocompromised hosts. Current therapies remain limited by suboptimal efficacy and toxicity, necessitating novel anti-toxoplasmic agents. Piceatannol (PIC), a natural stilbenoid, demonstrates multifaceted bioactivity including antimicrobial and anti-parasitic effects, suggesting therapeutic potential against T. gondii. Our previous study revealed PIC’s potent anti-parasitic activity, selectively inhibiting T. gondii proliferation and altering parasite morphology without host cytotoxicity. In this study, mechanistic analyses indicated that PIC disrupts mitochondrial integrity in tachyzoites, reducing mitochondrial membrane potential and ATP production while elevating ROS levels. Transcriptomic profiling identified significant suppression of oxidative phosphorylation-related genes, consistent with mitochondrial dysfunction. These findings establish PIC as a promising candidate targeting T. gondii through the mechanism of mitochondrial impairment. Full article

In onchocerciasis-endemic communities, black fly vectors of Onchocerca volvulus cause annoyance. No vector control was performed in Cameroon to complement ivermectin treatment despite high fly densities in the savannah and forest areas. This study assessed the knowledge and practices of four onchocerciasis-endemic communities in Sudan and the Guinea savannah in Cameroon. We surveyed four communities using a structured questionnaire. We interviewed 452 individuals (Mawong: 136, Befang: 160, Soramboum: 88, and Galim: 68) aged 14–50 years. Most respondents (90%) knew about black flies being a nuisance but had misconceptions about their bite’s effect, location, and season. Only 9.3% knew that black fly bites could lead to blindness, whereas 34.1% correctly regarded evenings as the biting period. In Savannah, Sudan, 30.9% of the interviewees stated that black flies bite both outdoors and indoors, and 37.0% of the enrolees believed that black flies bite any exposed body part. In the Guinea savannah, 61.1% of respondents agreed that black flies typically bite during the dry season. Proper clothing can protect against black fly bites, but the transmission mode and vector biology are poorly understood. Implementing community-based vector surveillance can help fight onchocerciasis and reduce black fly nuisance. Full article

Chicken coccidiosis costs the poultry industry over GBP 10 billion per year. The main method of preventing and controlling coccidiosis in chickens continues to be the use of drugs. Unfortunately, the prevalence of drug resistance in the field reduces or even eliminates the effectiveness of drugs, and drug residues in the food supply chain can also can be harmful to humans. Therefore, safe and effective anticoccidial drugs are urgently needed. Natural products have many advantages such as being safe, effective and inexpensive and are a sustainable way to control coccidiosis. In this study, the anticoccidial effects of six natural compounds were tested by Eimeria tenella infection. Oocyst production, cecum lesion, body weight gain, feed conversion ratio, and intestinal microbiota were measured. The results showed that nerolidol had a moderate effect on maintaining both body weight gain and feed conversion ratio. Silymarin and dihydroartemisinin showed significant anticoccidial effects by reducing total oocyst output. Dihydroartemisinin also significantly reduced the cecum lesion caused by Eimeria infection, but this compound may be toxic to the host at such informed doses because it decreases growth and survival rates. In addition, both silymarin and dihydroartemisinin partly restored the microbiota after challenge. This indicates that silymarin, dihydroartemisinin, and nerolidol are effective in the control of chicken coccidiosis. Our data provide basic knowledge about the anticoccidial effects of such natural compounds/derivates. Full article
