Article Synopsis
  • Current chemical drugs are ineffective for tick control and there are no effective vaccines, leading to the urgent need for new control strategies.
  • Small interfering RNAs (siRNAs) have potential to help control parasites, but their effectiveness is limited by challenges in getting them to the RNA-induced silencing complex (RISC).
  • This study developed a delivery system using chitosan nanoparticles to successfully transfect siRNAs into parasites, which reduced target gene expression and inhibited parasite growth, opening new avenues for gene therapy and understanding host-parasite interactions.

Article Synopsis
  • * A study focused on seven consanguineous families with azoospermia from rural Pakistan utilized whole-exome sequencing (WES) to find genetic variants linked to this condition.
  • * Researchers identified five harmful genetic variants across five families, contributing to the understanding of azoospermia's genetic basis, which could improve genetic counseling and lead to new treatments in the future.

Dog owners are greatly concerned about tick infestations in their pets. The prevalence and dispersion of ticks and their disease-causing microorganisms have been limited from the viewpoint of dog owners in Vietnam. This study investigated the presence of tick infestation and the pathogens associated with it in canines that were brought to veterinary hospitals in Vietnam.

Article Synopsis
  • Piroplasmosis is a tick-borne disease impacting livestock like camels, caused by parasites from the order Piroplasmida, with limited research on this issue in Egypt.
  • A study involving 181 blood samples from camels in Cairo and Giza found a 41.4% infection rate, identifying several piroplasmid species, including B. bovis, B. bigemina, and a first detection of T. equi genotype E in Egypt.
  • The research highlights the need for effective control strategies against piroplasmosis, particularly concerning B. microti, which poses potential risks to human health.

Vector-borne diseases indulge in severe economic losses in the livestock industry by adversely affecting cattle breeding in tropical and subtropical zone countries, including Turkey, encompassing a wide land area representing diverse climatic conditions. This study aimed to investigate significant bovine tick-borne piroplasm, rickettsia, and some other bacterial agents by genus- or species-specific PCR and nested PCR techniques in Turkey. A total of 210 cattle blood samples were collected from sixteen provinces in different geographical regions of Turkey.

Ticks play a pivotal role in propagating a diverse spectrum of infectious agents that detrimentally affect the health of both humans and animals. In the present study, a molecular survey was executed of piroplasmids in ticks collected from small ruminants in four districts within Konya province, Turkey. Microscopic examination identified 1281 adult ticks, which were categorized into 357 pools based on their species, sexes, host animals, and collection site before DNA extraction.

Malaria remains one of the most significant health issues worldwide, accounting for 2.6% of the total global disease burden, and efforts to eliminate this threat continue. The key focus is to develop an efficient and long-term immunity to this disease via vaccination or therapeutic approach, and innovative strategies would enable us to achieve this target.

Human babesiosis is a global emerging tick-borne disease caused by infection with intra-erythrocytic parasites of the genus . With the rise in human babesiosis cases, the discovery and development of new anti- drugs are essential. Phosphatidylinositol 4-kinase (PI4K) is a widely present eukaryotic enzyme that phosphorylates lipids to regulate intracellular signaling and trafficking.

Goats are key livestock animals and goat raising is an income-generating venture for smallholder farmers, supporting agricultural development in many parts of the world. However, goat production is often limited by various factors, such as tick-borne diseases. Goat piroplasmosis is a disease caused by apicomplexan parasites spp.

The protozoon is a blood parasite transmitted by hard ticks and commonly parasitizes ruminants such as cattle, buffaloes, goats, and sheep. Babesiosis, the disease caused by infection, has been considered a potential threat to ruminant production due to the grave and enormous impact it brings. About 125 million ruminants are at risk of babesiosis in Southeast Asia (SEA), a region composed of 11 countries.

Article Synopsis
  • Babesiosis can significantly harm immunocompromised individuals, and this study explored immune responses during acute co-infection using a mouse model.
  • Primary infections helped mitigate parasitemia by boosting specific immune responses early on, but co-infection weakened the splenic immune function, reducing critical B and T cells.
  • Cytokine analysis revealed that pro-inflammatory cytokines were downregulated while anti-inflammatory IL-10 increased, and differences in serum cytokine levels highlighted how timing of infection can influence disease severity.

Background: Drug resistance and toxic side effects are major challenges in the treatment of babesiosis. As such, new drugs are needed to combat the emergence of drug resistance in Babesia parasites and to develop alternative treatment strategies. A combination of naphthoquine (NQ) and artemisinin is an antimalarial therapy in pharmaceutical markets.

Tick-borne diseases (TBDs) considerably impair equine health and productivity. Moreover, TBDs, particularly equine piroplasmosis, impede international movement and trade of equids, which is a vital component of the global horse racing industry. In the Philippines, horse racing is a lucrative industry generating millions of USD annually.

Toxoplasmosis is a zoonotic parasitic disease caused by the obligate intracellular protozoa , which threatens a range of warm-blooded mammals including humans. To date, it remains a challenge to find safe and effective drug treatment or vaccine against toxoplasmosis. In this study, our results found that the development of a mutant strain based on gene disruption of dense granule protein 9 (gra9) in type II PLK strain decreased parasite replication , severely attenuated virulence in mice, and significantly reduced the formation of cysts in animals.
