Molecular detection of Theileria ovis (Apicomplexa: Theileriidae), Anaplasma ovis (Rickettsiales: Anaplasmataceae), and Mycoplasma sp. (Tenericutes: Mycoplasmataceae) from sheep blood in western Iran

This study is an investigation on tick-borne pathogens of domestic sheep, and aMycoplasma agent is reported for the first time in Iran.

We report a case of severe babesiosis caused by the bovine pathogen Babesia divergens with the development of multisystem failure in a splenic host. Immunosuppression other than splenectomy can also predispose people to B. divergens. There was heavy multiple invasion of up to 14 parasites inside the erythrocyte, which had not been previously observed even in asplenic hosts. The factors preventing the effectiveness of the vector Ixodes ricinus in the transmission of the organisms to humans are discussed.

Little information is available regarding the population dynamics of this tick in some regions, including north-eastern Brazil, where cases of tick-borne spotted fever are increasingly reported. Herein, we studied the phenology of A. sculp...

Abstract Despite close association between camels and humans, molecular based studies on vector-borne pathogens infecting camels are scarce compared to other animals in Iran. The current study was carried out to investigate the occurrence of vector-borne bacteria in the blood of dromedaries by molecular tools. A total of 200 peripheral blood samples were collected from apparently healthy animals. Microscopic examination was performed on Giemsa-stained blood smears, and drops of blood were spotted on Whatman FTA® cards for molecular analyses. Genomic DNA was extracted from the cards, and PCR amplification follo...

Comprehension of the etiology of R. parkeri infections in South America is complicated by the existence of genetic variants (Atlantic rainforest, NOD and Parvitarsum) of this species that are associated with specific groups of Amblyomma ticks. The rickettsial bacterium strain ApPR was firs...

In this study, a PCR/RFLP method, earlier developed for specific detection of A. platys-like strains in animal species other than camels, was adapted in order to subtype A. platys-like strains isolated from camels and their ticks and to differentiate them from pathogenic A. platys without going through a sequencing step. This approach was used for investigating the infections with A. platys and related strains in 412 Camelus dromedarius camels and 334 feeding ticks from five Tunisian governorates. Microscopic examination using Giemsa-stained blood smears was performed in order to specify which types of cells were infected....

This study aimed to investigate the tick species and give background for tick-borne investigations in Korea. Ticks were collected from the area within 2 km radius of the 4 domestic animal farms, where they were located in mountainous areas and raising animals on pasture, and from animal bodies in 2014 and 2015. In total, 7,973 nymphal and adult ticks were collected from the farms - 7,758 Haemaphysalis longicornis, 198 Haemaphysalis flava, and 17 Ixodes nipponensis, and 1,763 were collected from animals - 729 H. longicornis from cattle; 569 H. longicornis from goats; and 297 H. longicornis, 118 H. flava, 1 I. nipponensis, a...
