Babesia divergens is an intraerythrocytic protozoan parasite, transmitted by the tick Ixodes ricinus, and is the main agent of bovine babesiosis in Europe. It is not only a cause of significant loss to the cattle industry; it can also infect immunocompromised humans, causing medical emergencies characterized by rapid fulmination and parasitemias that may exceed 70%. The current emphasis in Europe on sustainable agriculture and extensification is likely to lead to an increase in vector tick populations with increased risk of infection. Despite the veterinary and zoonotic importance of this parasite, relatively little research has been carried out on B. divergens, and many questions regarding the parasite's epidemiology and the host's response remain unanswered. A better understanding of the species' biology and host-parasite interactions may lead to improved control mechanisms and new trends in vaccine and antibabesial drug development. This review provides the first comprehensive summary of B. divergens biology, including its morphology, life cycle, and host specificity, and the current state of knowledge of both human and bovine infections.

More than one-hundred species that affect animals and humans have been described, eight of which have been associated with emerging and underdiagnosed zoonoses. Most diagnostic studies in humans have used serology or molecular assays based on the 18S rRNA gene. Because the 18S rRNA gene is highly conserved, obtaining an accurate diagnosis at the species level is difficult, particularly when the amplified DNA fragment is small.

, major cause of bovine babesiosis with zoonotic potential, was analyzed through genomes Bdiv23B and Bdiv24B following Illumina sequencing of DNA extracted from PCR-positive cattle blood. The genomes comprised 3888 and 4032 predicted coding sequences, respectively, comparable to the reference genome, Rouen 1987, highlighting genomic consistency across isolates.

Tick-transmitted are a major global veterinary threat and an emerging risk to humans. Unlike their relatives, these erythrocyte-infecting Apicomplexa have been largely overlooked and lack specific treatment. Selective targeting of the proteasome holds promise for drug development.

We developed and evaluated a semi-nested PCR assay for the detection of infection in goats based on the sequence of the gene. Following in silico screening, the specificity of the primers was assessed using reference DNA samples, including , , , , , , , and . To determine the sensitivity of the method, blood infected with 2% parasitemia of was diluted to 10-fold serial dilutions.
