“…presented a tropism to the reproductive tract due to the production of erythritol, a 4-carbon sugar produced in the foetal tissues of ruminants that stimulates the growth of Brucella [82]. Thus, it may also explain the higher prevalence in adult animals than in young [83]. On the other hand, a higher prevalence of brucellosis in adults has also been associated with longer contact with infected animals or with the environment.…”

Brucella spp. 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. This disease also is responsible for a high economic impact associated with the application of prevention, surveillance and test-andslaughter programmes in animals by national authorities. Brucella spp. 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. 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. 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. Thus, to benefit from proper risk identification of brucellosis, it is essential to put a cost-effective and efficient brucellosis control programme into place.Keywords: Brucellosis, risk factors, animals, prevalence . IntroductionBrucellosis is a serious contagious disease that results in reproductive failure and has profound public health significance because of its zoonotic characteristics [ ]. 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 [ -]. 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 [ , ].Brucella spp. infects a large variety of animals as described in

“…This potential risk may be significant in those herds without culling of positive animals [84]. It must be kept in mind though that this low prevalence might be faulty because young animals can be infected without clinical symptoms presenting serologic response for only one week [83,84].…”
