Signal-dependent transport into and out of the nucleus mediated by members of the importin (IMP) superfamily is crucial for eukaryotic function, with inhibitors targeting IMPα being of key interest as anti-infectious agents, including against the apicomplexan species and , causative agents of malaria and toxoplasmosis, respectively. We recently showed that the FDA-approved macrocyclic lactone ivermectin, as well as several other different small molecule inhibitors, can specifically bind to and inhibit and IMPα functions, as well as limit parasite growth. Here we focus on the FDA-approved antiparasitic moxidectin, a structural analogue of ivermectin, for its IMPα-targeting and anti-apicomplexan properties for the first time.

Goats are the one of the most susceptible domestic species to toxoplasmosis affecting animal health and production. The present study aimed to determine the seroprevalence of T. gondii infection in dairy goats from Rio de Janeiro, Brazil, as well as to evaluate associated risk factors, parasitic DNA detection in raw goat milk samples, and attempts to isolate the parasite from raw goat milk samples.

Electronic address:
Avian coccidiosis, caused by protozoan parasites of the genus Eimeria, is a globally prevalent and highly pathogenic disease that poses a serious threat to the poultry industry, resulting in significant economic losses. However, the mechanism by which Eimeria species invade host cells remains unclear. Previous studies have identified rhoptry neck protein 2 (RON2) from Eimeria tenella as a critical factor in host cell invasion, but a comprehensive understanding of the role of EtRON2 in host cell invasion and its relationship with E.

Introduction: The World Health Organization (WHO) points out that infection by enteroparasites can affect ~3.5 billion people around the world. Hemodialysis (HD) patients may be more susceptible to infections by opportunistic pathogens due to impaired immune function.

Purpose: The objective of the study was to establish the prevalence of Sarcocystis (Apicomplexa, Sarcocystidae) in brown rats from Jleeb Al-Shuyoukh, Kuwait, and to describe detected parasites using morphological and DNA analysis methods.
Methods: Ninety-eight brown rats (Rattus norvegicus) were examined for Sarcocystis spp. Obtained sarcocysts were investigated using light microscopy and electron microscopy.
