Experimental transmissions of cloned Theileria parva in cattle with Rhipicephalus appendiculatus ticks were compared to transmissions with uncloned T. parva during studies on the potential for genetic recombination during syngamy of Theileria to produce antigenic diversity for evasion of bovine immunity. Prevalence and abundance of T. parva infection in adult ticks, which resulted from the feed...

Aquatic invasions are one of the major threats for freshwater ecosystems. However, in developing countries, knowledge biological invasions, essential implementation appropriate legislation, is often limited if not entirely lacking. In this regard, identification potentially invasive non-native species by risk screening, followed a full assessment ranked as higher risk, enables decision-makers t...

East Coast fever caused by Theileria parva parva has been eradicated from South Africa, but tick-borne infections with other species of Theileria still occur, particularly in cattle and African buffalo (Syncerus caffer). One such infection is Corridor disease caused by T. parva lawrencei, which is controlled by restricting the movement of African buffalo. Other species reviewed are T. parva bov...

East coast fever is a disease of cattle caused by Theileria parva and is transmitted by the tick Rhipicephalus appendiculatus. Buffalos are a natural reservoir of the parasite. The objectives of this study were to determine the T. parva infection in buffalo and cattle field samples, to identify genotypes of T. parva infecting cattle and buffalo and finally to investigate the presence of buffalo...

Theileria parva is the causative agent of Corridor disease in cattle in South Africa. The African buffalo (Syncerus caffer) is the reservoir host, and, as these animals are important for eco-tourism in South Africa, it is compulsory to test and certify them disease free prior to translocation. A T. parva-specific real-time polymerase chain reaction (PCR) test based on the small subunit ribosoma...

Understanding the fish community structure and spatial distribution characteristics is essential for appropriate reservoir fishery management, especially in early impoundment stage of reservoir, which could help obtaining basic data performing artificial adjustments to biological communities. On basis this concept, we conducted a survey at newly constructed southwest China by using combination ...
