Currently, the brucellosis status of a country is based on the epidemiology in domestic animals. In developed countries, brucellosis has been eradicated or presents low individual prevalence due to control programmes and vaccination of animals. The epidemiology of brucellosis is variable worldwide. ceti(cetaceans), Brucella pinnipedialis(seals), Brucella microti(voles) and Brucella inopinata.The last was isolated from a breast implant in a human with clinical signs of brucellosis. More recently, other species have been recognized such as B. Brucella abortus(cattle), Brucella melitensis(sheep and goats), Brucella suis(swine, cattle, rodents, wild ungulates), Brucella ovis(sheep), Brucella canis(dogs) and Brucella neotomae(rodents). Classically, the genus Brucellaincludes six recognized species based on antigenic/biochemical characteristics and primary host species. infects a large variety of animals as described in Table 1. However, a high economic impact is associated with the human disease and also by the application of prevention, surveillance and test-and-slaughter programmes in animals by national authorities. In animals, brucellosis can be considered as one of the most economically important zoonosis worldwide, resulting in clinical disease, abortion, neonatal losses, increased calving intervals, reduced fertility, decreased milk production, increased culling rates because of metritis and the emergency slaughtering of infected animals and also an impediment to free animal movement and trade. Thus, to benefit from proper risk identification of brucellosis, it is essential to put a cost-effective and efficient brucellosis control programme into place.īrucellosis is a serious contagious disease that results in reproductive failure and has profound public health significance because of its zoonotic characteristics. ![]() Although several risks have been identified, the most important have been associated with the biology of the bacteria, animal management (age, sex, species or breed), herd management (herd/flock size, number of species, contact with wild animals or type of animal production), farm management (facilities, cleaning and disinfection or veterinary support) and farmers’ knowledge about the disease. To achieve the control and eradication of brucellosis, the identification of the risk factors of brucellosis that maintain the infection in animals and/or the environment is fundamental. infects a large variety of animals and their prevalence is variable worldwide, mainly associated with the presence or absence of control programmes and also with the vaccination of animals against brucellosis. This disease also is responsible for a high economic impact associated with the application of prevention, surveillance and test-and-slaughter programmes in animals by national authorities. ![]() is the aetiological agent of brucellosis, a serious contagious disease that results in reproductive failure and that has profound public health significance because of its zoonotic characteristics.
