This comprises a group of infections caused by protozoan parasites of the genus Theileria and transmitted by ixodial ticks. They occur in a variety of ruminants and wild animals. Both members of the genus Babesia and the genus Theileria occur within red blood cells. They are collectively called piroplasms and the infections caused by the two are thus sometimes known as ‘piroplasmosis’.

Fowl cholera is a contagious, bacterial disease that affects domestic and wild birds worldwide. It usually occurs as a septicemia of sudden onset with high morbidity and mortality, but chronic and asymptomatic infections also occur.
Newcastle disease is an infection of domestic poultry and other bird species with virulent Newcastle disease virus (NDV). It is a worldwide problem that presents primarily as an acute respiratory disease, but depression, nervous manifestations, or diarrhea may be the predominant clinical form. Severity depends on the virulence of the infecting virus and host susceptibility. Occurrence of the disease is reportable and may result in trade restrictions.
