“…Dogs, cats and other wild carnivores such as foxes or wolves present an important role in the epidemiology of brucellosis, because they act as mechanical disseminators due to the transportation of infected foetuses or placentas from abortions in infected herds and flocks. Since pigs are susceptible to infection by B. melitensis, pig farms present some epidemiological importance where both species are reared [68]. In addition, wild ruminants with potential contact with infected sheep and/or goats could be infected with B. melitensis, maintaining the infection in natural environment [15].…”

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

“…Apart from its natural hosts, pigs, B. suis infection due to various biovars is reported in several non-natural host animal species. It is reported in cattle [12,19,20], dogs [12,[21][22][23], horses [24] sheep [25], reindeer, caribou, hares and various murine species [11,12,26] and humans [27]. Infections are transmitted through ingestion of contaminated materials or by co-habitation with infected animals.…”

Brucella suis (B. suis) is the major cause of porcine brucellosis. Zoonosis due to B. suis infection associated with transmission by various animal species is reported. Recently an increase in brucellosis associated with feral swine transmitted B. suis infection in humans and hunting dogs is emerging. Reports on B. suis infection in carnivores including dogs is scant. This report gives a brief review of B. suis zoonosis with particular reference to B. suis infection in dogs (carnivores).

“…The causative agent of brucellosis in goats and sheep is Brucella melitensis, while B. abortus, B. ovis, and B. suis may cause infections only under certain condition [3][4][5]. The major clinical manifestations of brucellosis in sheep and goats are abortion during the last two months of pregnancy, arthritis, fetal membrane retention, weak offspring, orchitis, epididymitis, and sterility [6].…”

Introduction: The objectives of the present study were to determine the seroprevalence and identify the causative agent of brucellosis in small ruminants in Pakistan. Methodology: A total of 278 serum and 212 milk samples were collected from sheep and goats that had close contact with seropositive bovine herds. Data related to age, sex, location, and breed were collected on the sampling day. Serum and milk samples were initially screened using two different Rose Bengal plate test (RBPT) antigens and a milk ring test (MRT). Seropositive samples were subjected to bacterial isolation and PCR analysis using Brucella genus-specific (bcsp31) and Brucella species-specific (IS711 for Brucella abortus and Brucella melitensis) quantitative real-time polymerase chain reactions (qRT-PCR). Results: Twenty-four (8.6%) serum samples were positive by RBPT. Twenty (9.4%) animals were positive for Brucella antibodies using MRT. No Brucella isolates were obtained from the examined blood and milk samples. Of the 24 seropositive serum samples, 18 (75%) were positive in the Brucella genus-specific (bcsp31) and Brucella abortus-specific (IS711) qRT-PCR, respectively. Conclusions: Brucella abortus was identified as causative agent of ovine and caprine brucellosis in Pakistan. Results of this study can be used for the development of an effective control and eradication strategy for brucellosis in livestock, especially small ruminants.
