At sites inoculated with D. congo-lensis , erythema will be apparent after 48 hours. Some serous exudation may be seen, and scab formation will occur after approximately 72 hours. These lesions will normally be uncontaminated, and D. congolensis can be demonstrated in the scabs or isolated from them. Serological tests Clinical diagnosis is best performed using the methods described above rather than serological methods. Antibody can be demonstrated in all but fetal blood in ruminants, but levels are raised following clinical infection.
Vaccines are under development but so far no commercial vaccines are available.
