Vicuñas (Vicugna vicugna) are wild South American camelids (SACs) protected by law in Argentina, and information on pathogens that infect them is scarce. In this study, an adult vicuña found dead in the province of Salta was examined, and evidence of infection by Sarcocystis sp. protozoans was sought.

Article Synopsis
  • Sarcocystis are protozoa that require both a predator (like humans) and a prey (like pigs) in their life cycle, with S. suihominis specifically affecting pigs as intermediate hosts.
  • Ingesting raw or undercooked pork containing these parasites can cause gastroenteritis in humans, leading to symptoms like nausea and diarrhea, and can spread the parasite through feces.
  • This study is notable for identifying S. suihominis in Nigeria for the first time using genetic analysis, highlighting a public health risk linked to pigs and poor hygiene practices on local farms.

Human babesiosis caused by the intraerythrocytic apicomplexan is an expanding tick-borne zoonotic disease that may cause severe symptoms and death in elderly or immunocompromised individuals. In light of an increasing resistance of to drugs, there is a lack of therapeutic alternatives. Species-specific proteases are essential for parasite survival and possible chemotherapeutic targets.

Competitive markets, increased fuel costs, and underutilized vehicle fleets are characteristics that currently define the logistics sector. Given an increasing pressure to act in a manner that is economically and ecologically efficient, mechanisms that help to benefit from idle capacities are on the rise. In the Sharing Economy, collaborative usage is typically organized through platforms that facilitate the exchange of goods or services.

Meat of the South American camelids (SACs) llama and alpaca is an important source of animal protein and income for rural families in the Andes, and a product with significant growth potential for local and international markets. However, infestation with macroscopic cysts of the coccidian protozoon Sarcocystis aucheniae, a parasitosis known as SAC sarcocystosis, significantly hampers its commercialization. There are no validated methods to diagnose the presence of S.
