“…The clinical signs of brucellosis in dogs range from asymptomatic course to abortion (Hollett, 2006;Ramamoorthy et al, 2011). Transmission of B. abortus from cattle to dogs has been suspected due to positive RBT (Cadmus et al, 2011) or Bruce-ladder PCR results (Truong et al, 2011). There has been an early attempt for isolation of B. abortus from dogs (Salem et al, 1974;Prior, 1976).…”

Brucellosis is highly contagious bacterial zoonoses affecting a wide range of domesticated and wild animals. In this study, Brucella (B.) abortus bv 1 was identified in uterine discharge of apparently healthy bitch and queen with open pyometra housed on a cattle farm. This study highlights the role of dogs and cats as symptomatic carriers and reservoirs for Brucella. To the best of our knowledge, this study represents the first report of feline infection with B. abortus bv 1 globally. These pet animals may contaminate the environment and infect both livestock and humans. Surveillance and control programmes of brucellosis have to include eradication of the disease in dogs, cats and companion animals.

“…B. abortus has been isolated from horses [33], [59], and antibodies have been reported in donkeys [60], dogs [61]–[63], and fowl [64]–[67] in Nigeria (Figure 2B). However, the role of these nonruminant species in disease transmission has never been satisfactorily proven [68] and, as they are unable to act as reservoirs, once brucellosis is eradicated in domestic ruminants, they are considered as spillover hosts or sentinels.…”

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

Nigeria is the most populous country in Africa, has a large proportion of the world's poor livestock keepers, and is a hotspot for neglected zoonoses. A review of the 127 accessible publications on brucellosis in Nigeria reveals only scant and fragmented evidence on its spatial and temporal distribution in different epidemiological contexts. The few bacteriological studies conducted demonstrate the existence of Brucella abortus in cattle and sheep, but evidence for B. melitensis in small ruminants is dated and unclear. The bulk of the evidence consists of seroprevalence studies, but test standardization and validation are not always adequately described, and misinterpretations exist with regard to sensitivity and/or specificity and ability to identify the infecting Brucella species. Despite this, early studies suggest that although brucellosis was endemic in extensive nomadic systems, seroprevalence was low, and brucellosis was not perceived as a real burden; recent studies, however, may reflect a changing trend. Concerning human brucellosis, no studies have identified the Brucella species and most reports provide only serological evidence of contact with Brucella in the classical risk groups; some suggest brucellosis misdiagnoses as malaria or other febrile conditions. The investigation of a severe outbreak that occurred in the late 1970s describes the emergence of animal and human disease caused by the settling of previously nomadic populations during the Sahelian drought. There appears to be an increasing risk of re-emergence of brucellosis in sub-Saharan Africa, as a result of the co-existence of pastoralist movements and the increase of intensive management resulting from growing urbanization and food demand. Highly contagious zoonoses like brucellosis pose a threat with far-reaching social and political consequences.

“…Infected animals usually serve as reservoirs of human infection (Namanda et al, 2009). Although, the overall proportion of B. canis causing human brucellosis is very low, its potential impact on population groups at the highest risk should not be underestimated as it poses a significant public health hazard since it is transmissible to humans especially those handling aborted foetuses (Cadmus et al, 2006). A prevalence rate of 7.6% occurred in 79 humans infected with canine brucellosis (Ofukwu et al, 2004).…”

“…Except in Nigeria (Cadmus et al, 2006), South Africa (Gous et al, 2005) and Zimbabwe (Gomo, 2013;Chinyoka et al, 2014), there is dearth of information on canine brucellosis in Africa. The increase in dog ownership in Nigeria is associated with some risk factors that render them vulnerable to brucellosis and many exotic breeds are imported that are not screened before entry into the country (Tafaderma, 2006;Ryhan et al, 2000).…”

Jos has a large population of dogs because of its cultural acceptance as meat, good weather condition for exotic breeds, persistent security challenges and dog breeding activities which is very lucrative. This study was undertaken to determine the risk factors and level of awareness of canine brucellosis among dog owners in Jos by means of a structured questionnaire. Three hundred and fifty respondents were interviewed and 350 sera samples collected from dogs presented by these respondents were analysed using the Rose Bengal plate test (RBPT). The seropositivity of 113 (32.3%) obtained by the RBPT was compared with information provided by the respondents. Seropositivity of dogs managed indoors was 13.9% whereas it was 37.1% in those managed outdoors. A large proportion of 76.9% of the respondents lacked knowledge of canine brucellosis. Likewise, 81.4% of the respondents took no precaution before and after dog handling and a large proportion of 74.6% consumed undercooked dog meat. This study showed that there is a high risk of exposure of dog owners, handlers and Veterinarians to the disease and therefore enlightenment programmes on canine brucellosis as a zoonosis should be carried out in Jos.
