In the United States,<unk>  is notably present in the South and West, where the tick hosts Ixodes spp. are found. It is also a seemingly increasing antibody in humans in Europe. Although vaccines have been developed, none are currently available in the United States. Early in the 20th century, this disease was considered one of major economic consequence in the Western United States. In the 1980s and 1990s, control of ticks through new acaricides and practical treatment with prolonged-action antibiotics, notably tetracycline, has led to the point where the disease is no longer considered a major problem. The disease affects immunoglobulin G, therefore G-specific antibody levels can be used to diagnose the disease. In 2005, A. ovis was found in reindeer populations in Mongolia. This pathogen and its associated syndrome (characterized by lethargy, fever, and pale mucous membranes) was previously observed in only wild sheep and goats in the region, and is the first observed occurrence of A. ovis in reindeer. In Australia, bovine<unk> , caused by A. marginale, is found in only the northern and eastern parts of Australia where the cattle tick is present. It was probably introduced as early as 1829 by cattle from Indonesia infested with the cattle tick Boophilus microplus. The veterinarian George P. Broussard of New Iberia, Louisiana, conducted important research on<unk>  and brucellosis.
