African Horse Sickness

 

a chronic infectious disease of horses, mules, and asses, characterized by the formation of abscesses along the passage of the lymph vessels.

African horse sickness is distributed in India, Burma, the Sudan, Sweden, and some other countries. In the USSR it was eliminated in 1960. The mortality rate is 10 to 20 percent. The causative agent is a fungus, Cryptococcus farciminosus. The source of the infectious agent is diseased animals. Factors in the transmission of the causative agent are infected objects of care and fodder. Infection occurs through injured skin, the respiratory tract, and the digestive tract. Insects may also transmit the disease. Unsatisfactory conditions of care and feeding promote the spread and prolong the course of the disease. The fungus is localized in the skin, subcutaneous tissue, and lymph vessels. Wherever it is embedded, nodes are formed. The nodes are followed by abscesses, which open to reveal ulcers. Multiple infections may be complicated by pyogenic infection and death of the animal.

African horse sickness may be treated by removing nodes, ulcers, and affected lymph nodes and vessels and administering acriflavine, distilled preparation of Ranunculus, and preparation ASD (anticeptum dorochovi). Preventive measures include the observance of sanitary conditions in managing, feeding, and caring for animals. When cases of the disease appear, the farm is quarantined.

African horse sickness virus (AHSV), equine encephalosis virus (EEV), and equine herpesviruses (EHV) 1 and 4 were identified by using viral culture and antigen detection assays and/or complement fixation tests (31) on serum samples and using RT-PCR to detect AHSV and EHV (32).
Other species of the orbiviruses are African horse sickness virus, epizootic hemorrhagic disease virus (EHDV), and some lesser-known viruses such as Peruvian horse sickness virus, Chuzan virus, Saint Croix River virus, and Yunnan orbivirus (2).
