“…Bovine brucellosis caused by Brucella abortus results in abortions in female cattle and infertility in male cattle that are infected and discharge bacteria in their semen [4][5][6]. Bovine brucellosis is widely seen in most parts of the world except for some countries such as Australia, Japan, and northern Europe (OIE, 2005).…”

“…Although most of these species have a wide range of hosts, B. abortus is the main causative agent of brucellosis in bovine [4,6]. Infection with B. abortus showed the long and variable incubation period and the occurrence of latent infection in calves born to infected cows without serological response upon future infection [5,7,8]. Also, the bacteria can survive inside the cells of the infected host by creating a membrane-bound compartment that prevents their fusion with lysosomes and supports intracellular replication [7,9].…”

“…Among the serological tests, the standard tube agglutination test is recognized as the standard method for the diagnosis of bovine brucellosis in OIE. Several vaccines, including inactivated and live attenuated vaccines, against bovine brucellosis have been used in many regions of the world for the prevention and control of the disease [5][6][7]. However, the use of vaccine differs depending on the prevalence of the disease and the eradication program in the countries.…”

Abstract. The incidences of reproductive disorders in bovine are increasing over years. This scenario is further aggravating due to more emphasis on selection and rearing of animal for specific commercial purposes which compromises livestock reproduction. Reproductive disorders like infertility and abortions in cattle are major problems in the bovine industry. The reproductive disorders might be caused by several different agents such as physical agents, chemical agents, biological agents, etc. Also, the causative agent and pathogenesis of reproductive disorders are influenced by various factors including environmental factor. The exact causes may not be evident and are often complicated with multiple causative agents. Thus, there is a need for multi-faceted approach to understand correlation of various factors with reproductive performance. Of the agents, infectious biological agents are significant cause of reproductive disorder and are of high priority in the bovine industry. These factors are not only related to the prosperity of bovine industry but are also important from public health point of view because of their zoonotic potentials. Several infectious agents like bacterial, viral, protozoon, chlamydial and fungal agents are known to have direct impact on reproductive health of cattle. These diseases can be arranged and discussed in different groups based on the causative agents.

“…The disease mainly affects reproduction and fertility in females, thereby reducing survival of newborns, and reducing milk yield (Sewell and Brocklesby, 1990;Zinsstag et al, 2005). In industrialized countries, effective control measures are implemented for eradication, including intensive national surveillance systems in animals and removal of infected livestock (Pappas et al, 2005;Lithg-Pereira et al, 2004;Yamamoto et al, 2008;Lee et al, 2009). However, developing countries rarely have national programs to prevent, control, monitor and eradicate brucellosis in animal populations.…”

a b s t r a c tThis study aimed to determine whether variations in the incidence of reported cases of human brucellosis in Ecuador were clustered in space and time. In addition, the effects of cattle and small ruminant population density and other socio-economic factors on the incidence were investigated. Significant space-time clusters were found in the northern and southern highlands and parts of Ecuadorian Amazonia. Customs of people, cattle, goat and sheep population density appeared to influence the incidence of brucellosis. In this study, the incidence of reported cases of human brucellosis was found to be higher in the highlands (sierra) and in municipalities near Peru and Colombia. The results of this study highlight the need for prevention and control measures aimed at abating the incidence of brucellosis among livestock and humans.

SUMMARY:This study concerns the quantitative analysis of brucellosis outbreaks and the related risk factors and control programs for both domestic cattle and human brucellosis infections in Korea between 2002 and 2009. There were a total of 77,082 infections of bovine brucellosis (BB) in domestic cattle with a prevalence rate (PR) of 13.3 per 1,000 cattle; during the same period there were 620 cases of human brucellosis (HB) with a PR of 0.16 per 100,000 persons. Moreover, the correlation coefficient of brucellosis outbreaks between cattle and humans was highly significant (r ＝＋0.985). The attack ratio of HB cases was 8.04 per 1,000 BB cases. The distribution of brucellosis outbreaks was concentrated in the southeast region of Korea ( P º 0.01). Significantly more males were infected than females (86.9z versus 13.1z), and a high incidence of HB was observed in those aged more than 40 years (86.1z). The majority of HB cases occurred primarily among rural inhabitants (92.3z) and among farmers and related workers (47.9z). Finally, all of the measures that were applied in the extensive eradication program for brucellosis outbreaks and control were based principally on an intensive test-and-slaughter policy and contributed significantly to the reduction in the outbreaks of brucellosis in Korea.Brucellosis is a worldwide zoonotic infection in animals and humans caused by the Brucella spp. including Brucella melitensis, Brucella abortus, Brucella suis, and Brucella canis; moreover, marine mammal strains are known to be pathogenic agents in humans (1,2).
