Evaluation of Theileria equi vertical transmission rate and routes in a cohort of asymptomatic mares and their foals.

Equine piroplasmosis is a tick-borne disease mainly caused by Theileria equi and Babesia caballi. The objectives of this study were to analyse the frequency and routes of vertical transmission of these blood parasites from 179 asymptomatic mares to their foals. Foals were sampled within 72 h post-partum.

Surveillance of avian malaria and related haemoparasites in common terns () on the Atlantic coast of South America.

Haemosporidia (Apicomplexa, Haemosporida) are protozoa that infect vertebrate blood cells and are transmitted by vectors. Among vertebrates, birds possess the greatest diversity of haemosporidia, historically placed in 3 genera: , and , the causative agent of avian malaria. In South America, existing data on haemosporidia are spatially and temporally dispersed, so increased surveillance is needed to improve the determination and diagnosis of these parasites.

The New Human sp. FR1 Is a European Member of the sp. MO1 Clade.

In Europe, is responsible for most of the severe cases of human babesiosis. In the present study, we describe a case of babesiosis in a splenectomized patient in France and report a detailed molecular characterization of the etiological agent, named sp. FR1, as well as of closely related , and sp.

Characterization and diversity of Babesia sp. YLG, a new member of the Peircei group infecting Mediterranean yellow-legged gulls (Larus michahellis).

Avian infecting piroplasms are largely under-studied compared to other hemoparasites, and this paucity of information has blurred our phylogenetic and biological comprehension of this important group as a whole. In the present study, we detected and characterized Babesia from yellow-legged gull (Larus michahellis) chicks from a colony in southern France. Based on morphological and molecular characterizations, a new Babesia species belonging to the Peircei group, a clade of avian-specific piroplasms, was identified.

RAP-1a is the main rhoptry-associated-protein-1 (RAP-1) recognized during infection with Babesia sp. BQ1 (Lintan) (B. motasi-like phylogenetic group), a pathogen of sheep in China.

Babesia sp. BQ1 (Lintan) is one of the parasites isolated from infected sheep in China that belongs to the B. motasi-like phylogenetic group.
