“…Indicating that infection of brucellosis is dependent on breed (P<0.05). Bertu et al (2011) found out that, in the Benue state in Nigeria, Red Fulani breed recorded 11.1% serprevalence against 10.4% for the White Fulani. In another study using the Red Fulani and the Bunaji breed, Cadmus et al (2008) found that the Red Fulani breed had the most positive reaction.…”

“…The vulnerability is more pronounced with dairy production units which have developed around rapidly growing urban centres. The disease is present throughout the African continent (Chimana et al, 2010;Matope et al 2011;Megersa et al, 2011) and has also been reported in two of Cameroon's neighboring countries, Nigeria and Chad (Bertu et al, 2011;Schelling et al, 2003).…”

“…The limitation of data on the seroprevalance of the disease and the non-reliability of that available necessitates a study for the development of control measures aimed at improving productivity in Cameroon (Bertu et al, 2011). This work is therefore aimed at assessing the seroprevalence of brucellosis in the Nkwen abattoir in the North West Region of Cameroon, one of the major cattle producing areas in Cameroon.…”

Brucellosis is one of the most notorious and widespread zoonosis caused by Brucella abortus. It is of serious economic implications to the cattle industry and thus enormous financial losses to most countries. This study focused on it serological prevalence at the Nkwen main abattoir of Bamenda (Northwest region, Cameroon) from June to September 2013. Blood samples were collected from 198 cattle and the sera were screened using the competitive enzyme linked immuno sorbent assay (C-ELISA). Results showed a seroprevalence of 4.04% in the cattle population screened. A percentage of 4.40% of the 111 bulls and 3.45% of the 87 cows were recorded as infected. There was no evidence (P>0.05) of differences in sex on the seroprevalence of brucellosis in cattle. There was no association between brucella infection and age (P>0.05). About three percent of cattle were positive for those within (<5) age group with 5(4.67%) for those above 5 years of age. The two breeds commonly consumed in the area the Red and White Fulanie with the Red Fulani having a higher infection than the White Fulani (P<0.05). The study also showed that Brucella infection was dependent on location as 5 out of the 15 villages accounting for 100% infection namely: Fundong (37.5%), Wum (25%), Nso (Jakiri) (12.5%), Metah (12.5%) and Fonta (12.5%). From these results it was concluded that brucellosis is present in the population of cattle screened. There is therefore the need for good control measures and sanitary conditions to limit the spread of the disease.

“…However, contemporary assessments indicate a lower prevalence than that presented by Akakpo. Serological evidence of its existence has been demonstrated in many studies in sub-Saharan countries like Côte d'Ivoire (Sanogo et al 2013), Uganda (Kashiwazaki et al 2012), Ethiopia (Asmare et al 2013), and Togo (Dean et al 2013), and in particular some neighboring countries to Chad, notably from the southwest where the study area borders Nigeria (Alausa et al 1976, Bertu et al 2012, Mai et al 2012.…”

The seroprevalence of Rift Valley fever (RVF), brucellosis, and Q fever among domestic ruminants on the southeastern shore of Lake Chad was studied. The study area consisted of two parts, including mainland and islands. On the mainland, the study was conducted in nine randomly selected villages and camps. On the islands, samples were collected from all four available sites. A total of 985 serum samples were collected and 924 were analyzed using enzyme-linked immunosorbent assay (ELISA) for RVF. A total of 561 samples collected from islands were analyzed using ELISA for Q fever and both ELISA and Rose Bengal tests (RBT) for brucellosis. The apparent RVF seroprevalence by species was 37.8% (95% confidence interval [CI] 34.2-41.3) in cattle, 18.8% (95% CI 12.3-25.2) in goats, and 10.8% (95% CI 3.0-18.5) in sheep. For brucellosis and Q fever, only cattle samples from islands were analyzed. For Q fever, the apparent seroprevalence was 7.8% (95% CI 5.6-10.1). For brucellosis, the RBT showed a prevalence of 5.7% (95% CI 3.8-7.6), and ELISA showed 11.9% (95% CI 9.3-14.6) with a kappa value of 0.53 showing a moderate agreement between the two tests. This study confirms the presence of the three diseases in the study area. More research is required to assess the importance for public health and conservation of the Kouri cattle breed.

“…Recent investigations based on serological studies have shown that bovine brucellosis is endemic in Nigeria (Abdou 2000;Ate et al 2007;Cadmus et al 2010) and that there is an apparent increase in its occurrence in the country (Junaidu, Oboegbulem & Salihu 2011;Ocholi et al 2004). Previous reports have indicated that the prevalence of bovine brucellosis may be influenced by herding different species together (Bale, Nuru & Addo 1982;Junaidu, Oboegbulem & Salihu 2008;Ocholi et al 2004), use of common pastures and water sources (Bertu et al 2012), age (Cadmus, Adesokan & Stack 2008;Junaidu et al 2011;Ocholi et al 1996), breed (Cadmus et al 2008;Esuruoso 1974), sex (Atsanda & Agbede 2001;Junaidu et al 2011), lactation status (Junaidu et al 2011) and season (Bertu et al 2012;Nuru & Dennis 1976). However, the role of different cattle production systems needs to be assessed given the uncontrolled free movement of animals, especially as practised by the Fulani herdsmen, and unsupervised introduction of new animals into herds.…”

Limited data are available on the risk factors responsible for the occurrence of brucellosis amongst different cattle production systems in Nigeria despite its significant impact on livestock production. Consequently, a cross-sectional study was conducted to determine the prevalence of bovine brucellosis in three cattle production systems in Yewa Division of Ogun State, south-western Nigeria. A total of 279 blood samples (sedentary = 88; transhumance = 64; trade = 127) were examined for antibodies to Brucella sp. using the Rose Bengal test (RBT) and competitive enzyme-linked immunosorbent assay (cELISA). Overall, 24 (8.6%) and 16 (5.7%) of the animals tested seropositive for Brucella using RBT and cELISA, respectively. The herd seroprevalences based on RBT and cELISA were 31.6% and 15.8%, respectively. The results using cELISA reveal higher seroprevalence in the trade cattle (7.9%; confidence intervals [CI] = 3.2% - 12.6%) and those in a sedentary system (5.7%; CI = 0.9% - 10.5%) than in cattle kept under a transhumant management system (1.6%; CI = 1.5% - 4.7%). Age (> 3 years; p = 0.043) and breed (Djali; p = 0.038) were statistically significant for seropositivity to brucellosis based on cELISA, but sex (female, p = 0.234), production system (trade and sedentary; p = 0.208) or herd size (> 120; p = 0.359) was not. Since breeding stock is mostly sourced from trade and sedentary cattle, it is important that routine serological screening should be conducted before introducing any animal into an existing herd.

Serological evidence for brucellosis in Bos indicus in Nigeria

Abstract: The results indicate that bovine brucellosis is an important veterinarian problem in Nigeria. The easy-to-use and robust field test is most promising for field-based surveillance as it provides an immediate result allowing the prompt instigation of control measures.
