Brucellosis as an Emerging Threat in Developing Economies: Lessons from Nigeria: e3008

There is a paucity of science-based evidence on brucellosis in sub-Saharan Africa [1], [4], [11]-[13], and an appraisal of historical and contemporary epidemiology (prevalence estimates, affected host species, potential reservoirs and Brucella species) is key to implementing measures for sustainable...

Description
Summary:There is a paucity of science-based evidence on brucellosis in sub-Saharan Africa [1], [4], [11]-[13], and an appraisal of historical and contemporary epidemiology (prevalence estimates, affected host species, potential reservoirs and Brucella species) is key to implementing measures for sustainable management of this disease. Nigeria is the most populous country in Africa (over 170 million in 2012; http://esa.un.org/wpp/ASCII-Data/DISK_NAVIGATION_ASCII.htm) and has an estimated livestock population of 20.49 million cattle, 23.07 million sheep, 28.07 million goats, 6.54 million pigs (http://www.fao.org/ag/againfo/resources/en/glw/GLW_dens.html), 18,200-90,000 camels, and 210,000 horses (http://faostat.fao.org/site/573/default.aspx#ancor) [14]. Establishment of Government Veterinary Field and Research Centres (Zaria, 1913; headquarters moved to Vom in 1924; expanded to include vaccine production). * 1930s.\n * The few attempts to implement a vaccination plus test and slaughter strategy in cattle show that this approach was not sustainable. * The role of small ruminants and camels in the epidemiology of brucellosis in Nigeria remains unknown because of insufficient bacteriological investigations and, for camels, properly validated serological tests. * The extent of the public health impact of brucellosis is largely unknown, and bacteriological studies to characterise the Brucella species infecting humans are lacking. * There is an imperfect understanding of the animal and human disease and of the value of the different diagnostic tests in different epidemiological contexts.
