Morphological, Ultrastructural, and Histopathological Characterization of Natural Rhipicephalus annulatus Infestation in Sheep Skin From Kerbala Province, Iraq

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Ticks constitute most epidemiologically important group of ectoparasites in the veterinary medicine, causing direct host injury and serving as obligate vectors for many pathogenic organisms. The present study was designed for providing an integrated morphological, ultrastructural, and histopathological characterization of Rhipicephalus annulatus that ...

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.

Investigation of the Blood Microbiome in Horses With Fever of Unknown Origin

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
ABSTRACT Background Fever of unknown origin (FUO) without a respiratory component is a frequent clinical presentation in horses. Multiple pathogens, both tick‐borne and enteric, can be involved as etiologic agents. An additional potential mechanism is intestinal barrier dysfunction.

Identification of a putative methyltransferase gene of Babesia bigemina as a novel molecular biomarker uniquely expressed in parasite tick stages

Parasites & Vectors, 2018
Background Bovine babesiosis is caused by apicomplexan pathogens of the genus Babesia such as B. bigemina and B. bovis. These tick-borne pathogens have a complex life-cycle involving asexual multiplication in vertebrate hosts and sexual reproduction in ...

Epidemiology of Ticks and Tick‐Borne Hemopathogens of Cattle in Two Selected Districts of Northwest Ethiopia

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
The overall prevalence of tick infestation and tick‐borne haemopathogens of cattle in the study area was 87.8% and 17.1%, respectively. Five species of ticks under three genera were detected; namely: Amblyomma variegatum, Amblyomma lepidum, Rhipicephalus evertsi, Hyalomma rufipes and Rhipicephalus decoloratus were identified.

Proteomic Identification and Functional Analysis of Babesia microti Reveals Heparin‐Binding Proteins

Journal of Tropical Medicine, Volume 2025, Issue 1, 2025.
Glycosaminoglycan (GAG) molecules on the surface of red blood cells play an important regulatory role in the invasion of merozoites of apicomplexan protozoa. Heparan sulfate, a type of GAG molecule, has been identified as an important receptor facilitating the invasion of red blood cells by these parasites.

Mapping the Global Distribution of Babesia Infections

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Understanding the ecological niches and quantifying the disease burden of Babesia species is essential for efficient surveillance and control strategies. Through a systematic review of global distributions, we document all 250 identified Babesia species across 73 vector species, 224 animals, and humans.
