Transplacental transmission of Theileria orientalis occurs at a low rate in field-affected cattle: infection in utero does not appear to be a major cause of abortion

Parasites & Vectors, 2017
Background Bovine theileriosis, caused by the haemoprotozoan Theileria orientalis, is an emerging disease in East Asia and Australasia. Previous studies have demonstrated transplacental transmission of various Theileria spp. but molecular confirmation of

Dermacentor variabilis Does Not Transstadially Transmit the U.S. Isolate of Theileria orientalis Ikeda: A Controlled Acquisition and Transmission Study

Parasitologia, 2023
Theileria orientalis Ikeda, an emerging U.S. bovine hemoparasite, causes anemia, abortion, ill-thrift, and occasionally death. While Haemaphysalis longicornis is the primary vector, it is possible that other U.S.

Molecular characterisation of Theileria orientalis in imported and native bovines from Pakistan [PDF]

Infection, Genetics and Evolution, 2017
The epidemiological aspects of Theileria orientalis in Pakistan are unknown; therefore, investigations using sensitive and precise molecular techniques are required. This study reports the first molecular characterisation of T. orientalis detected from imported (Bos taurus) and native cattle (Bos indicus×Bos taurus) and buffaloes (Bubalus bubalis ...

An outbreak of haemolytic anaemia associated with infection ofTheileria orientalisin naïve cattle

New Zealand Veterinary Journal, 2011
An outbreak of haemolytic anaemia occurred when 87 cattle were introduced from a presumed non-infected herd from south Otago to a herd in Northland (n=580 cows), New Zealand, where theileriosis is endemic.Clinical signs associated with Theileria spp.

Role of Recognition MicroRNAs in <i>Hemaphysalis longicornis</i> and <i>Theileria orientalis</i> Interactions. [PDF]

Pathogens
Ticks are an important type of pathogen transmission vector, and pathogens not only cause serious harm to livestock but can also infect humans. Because of the roles that ticks play in disease transmission, reducing tick pathogen infectivity has become increasingly important and requires the identification and characterization of these pathogens and ...

Development and validation of a real-time SYBR green PCR method for the detection and differentiation of Babesia and Theileria species (Apicomplexa: Piroplasmida) in hard ticks and cattle blood from Thailand [PDF]

Parasite
Tick-borne pathogens, particularly Babesia and Theileria species, are major threats to cattle production, causing economically significant diseases such as babesiosis and theileriosis.

Molecular detection and genetic identification of Babesia bigemina, Theileria annulata, Theileria orientalis and Anaplasma marginale in Turkey

Ticks and Tick-borne Diseases, 2016
Babesia spp., Theileria spp. and Anaplasma spp. are significant tick-borne pathogens of livestock globally. In this study, we investigated the presence and distribution of Babesia bigemina, Theileria annulata, Theileria orientalis and Anaplasma marginale in cattle from 6 provinces of Turkey using species-specific PCR assays.

Evaluation of the efficacy of ivermectin against Theileria orientalis infection in grazing cattle. [PDF]

BMC Vet Res, 2019
Raising cattle on pastures is known to be beneficial for animal welfare and cost reduction. However, grazing is associated with the risk of contracting tick-borne diseases, such as theileriosis. Here, the efficacy of ivermectin against these diseases and associated clinical symptoms were evaluated.A total of 68 cattle from a grazing cattle farm were ...

Hematological Changes Associated with Theileria orientalis Infection in Korean Indigenous Cattle. [PDF]

Korean J Parasitol, 2017
Tick-borne pathogens can cause serious problems in grazing cattle. However, little information is available on tick-mediated diseases in cattle grazing on mountains. Thus, this study aimed to understand the potential problems related to tick-borne diseases in grazing cattle through the investigation of prevalent tick-transmitted infections, and their ...

Detection of Theileria orientalis genotypes in Haemaphysalis longicornis ticks from southern Australia [PDF]

Parasites & Vectors, 2015
Background Theileria are blood-borne intracellular protozoal parasites belonging to the phylum Apicomplexa. Previously considered a benign parasite in Australia, outbreaks of clinical disease resulting from Theileria orientalis genotypes have been ...
