A survey of piroplasms in white-tailed deer (Odocoileus virginianus) in the southeastern United States to determine their possible role as Theileria orientalis hosts

International Journal for Parasitology: Parasites and Wildlife, 2022
In 2017, clinical disease and mortality in cattle associated with Theileria orientalis Ikeda was reported in Virginia, U.S. The exotic tick, Haemaphysalis longicornis, is a competent vector for this species. White-tailed deer (Odocoileus virginianus) are

Pomegranate (Punica granatum) Peel Inhibits the In Vitro and In Vivo Growth of Piroplasm Parasites

, 2022
Pomegranate (Punica granatum) peel has seen a rapid surge in attention as a medical and nutritional product over the last decade. The impact of pomegranate peel methanolic extract monotherapy and combination therapy on the in vitro growth of Babesia (B.)

Experimental infection of horses with African horse sickness virus results in overt disseminated intravascular coagulation

Equine Veterinary Journal, Volume 58, Issue 2, Page 619-629, March 2026.
Abstract Background African horse sickness (AHS), caused by the vector‐borne African horse sickness virus (AHSV), is endemic to sub‐Saharan Africa and infection results in high mortality in naïve equine populations. Clinical signs include submucosal petechiae and prolonged bleeding post venepuncture indicative of hypocoagulation.

First molecular survey of piroplasm species in cattle from Kyrgyzstan

, 2019
Bovine piroplasmosis is a tick-borne disease caused by apicomplexan hemoparasites of the genera Theileria and Babesia. This study was carried out to assess the presence and frequency of piroplasm parasites in apparently healthy cattle in Kyrgyzstan.

Insights on the phenology of the Asian longhorned tick (Haemaphysalis longicornis) using stored lipids

Insect Science, Volume 33, Issue 1, Page 396-406, February 2026.
Lipid analysis of field‐collected ticks unveiled a complex population structure and supports the potential for several stages to overwinter. Abstract The seasonality of Haemaphysalis longicornis in the United States comprises overlapping life stages in the spring and summer.

Molecular identification and characterization of piroplasm species in Hokkaido sika deer (Cervus nippon yesoensis), Japan [PDF]

, 2017
Babesia and Theileria species are tick-borne protozoan parasites that have a veterinary and zoonotic importance. In order to investigate the prevalence and genetic diversity of these parasites, a total of 269 sika deer blood DNA samples collected from ...

Targeted Next-Generation Sequencing and Informatics as an Effective Tool to Establish the Composition of Bovine Piroplasm Populations in Endemic Regions. [PDF]

, 2021
Protists of the genera Babesia and Theileria (piroplasms) cause some of the most prevalent and debilitating diseases for bovines worldwide. In this study, we established and used a next-generation sequencing-informatic approach to explore the composition

Spatiotemporal Dynamics of Blood Parasite Infections and Impacts on Avian Health and Reproduction

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Parasitic infections are ubiquitous in nature, but their consequences are often difficult to evaluate in wildlife. This is particularly the case for chronic infections for which fitness impacts can be subtle or confounded with other intrinsic and extrinsic factors.

In Vitro Monitoring of Babesia microti Infection Dynamics in Whole Blood Microenvironments

Advanced Science, Volume 12, Issue 41, November 6, 2025.
Here, an open microfluidic platform termed “µ‐Blood” is reported for real‐time, continuous monitoring of Babesia microti infection dynamics in vitro. µ‐Blood allows direct interrogation of whole blood with preserved integrity of the original whole blood microenvironment through an extended period (e.g., 72 h with mouse red blood cells) ex vivo. µ‐Blood

Identification of a 40S ribosomal protein (S17) that is differentially expressed between the macroschizont and piroplasm stages of Theileria annulata

, 2002
The nucleotide and protein sequence of the 40S ribosomal protein S17 (RibS17) of the protozoan parasite Theileriaannulata has been determined. Southern blot analysis showed the gene was single copy and comparative sequence analysis revealed that the ...
