Lymphocytes and macrophages are infected by Theileria equi, but T cells and B cells are not required to establish infection in vivo. [PDF]

PLoS ONE, 2013
Theileria equi has a biphasic life cycle in horses, with a period of intraleukocyte development followed by patent erythrocytic parasitemia that causes acute and sometimes fatal hemolytic disease. Unlike Theileria spp. that infect cattle (Theileria parva

Tick‐borne pathogen interactions enhance transmission in cattle and ticks in Ogun, Nigeria

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Tick‐borne diseases (TBDs) pose a major public health concern in tropical regions, where co‐infections and pathogen interactions complicate disease control. Understanding how these interactions vary across vertebrate hosts and tick vectors, and their impact on disease transmission, is crucial for developing effective intervention strategies ...

Distribution of Ticks and Prevalence of Tick‐Borne Pathogens in Multiple Regions of China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Ticks and tick‐borne pathogens pose significant threats to livestock and public health. While tick occurrences have been reported in China, systematic assessments of pathogen risk factors across diverse hosts and regions remain limited. This study investigated tick distribution, prevalence, and associated pathogen infections across seven sampling sites

Comparative pathogenicity ofTheileria annulatastrains

Veterinary Quarterly, 1987
Twenty three susceptible crossbred calves were inoculated with five Indian strains of Theileria annulata, collected from natural cases of tropical theileriosis at Ludhiana, Hissar, Jaipur, Uruli-Kanchan and Bangalore. All the strains produced clinical disease with typical symptoms and lesions of acute theileriosis.

Two Theileria parva CD8 T cell antigen genes are more variable in buffalo than cattle parasites, but differ in pattern of sequence diversity [PDF]

, 2011
<p><b>Background:</b> Theileria parva causes an acute fatal disease in cattle, but infections are asymptomatic in the African buffalo (Syncerus caffer).

A One Health Assessment of Tick and Tick‐Borne Pathogen Diversity and Zoonotic Risk in Hubei Province, Central China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Ticks and tick‐borne pathogens (TBPs) threaten livestock productivity and public health worldwide, and climate–land‐use change is expanding vector habitats, elevating tick‐borne disease risk. However, TBP diversity and risk in Hubei Province, central China, remain insufficiently defined within a One Health framework.

Population diversity and multiplicity of infection in Theileria annulata

International Journal for Parasitology, 2011
The tick-borne apicomplexan parasite Theileria annulata is endemic in many sub-tropical countries and causes the bovine disease tropical theileriosis. Although the parasite is known to be highly diverse, detailed information is lacking on the genetic structure of natural populations and levels of multiplicity of infection in the cattle host.

Transformation of leukocytes by Theileria parva and T. annulata. [PDF]

, 1999
Theileria parva and T. annulata provide intriguing models for the study of parasite-host interactions. Both parasites possess the unique property of being able to transform the cells they infect; T. parva transforms T and B cells, whereas T.

Spatial Heterogeneity of Tick‐Borne Pathogens Outpaces Genetic Structuring in Anatolian Dermacentor reticulatus Populations

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Understanding how vector population structure influences pathogen circulation remains a major challenge in tick‐borne disease ecology, particularly in biogeographically transitional regions. Dermacentor reticulatus, a widespread Palearctic tick species and vector of multiple pathogens, provides a useful system to investigate this relationship in a ...
