“…Our estimated seroprevalence of 8.9% (cELISA) was in agreement with the 7.6% seroprevalence of brucellosis reported using the (Belal & Ansari, 2013). The results were also consistent with previous country-wide estimates of 2.4%-8.4% made using the iELISA (Rahman et al, 2006).…”

“…Brucellosis is endemic in both humans and animals in Bangladesh (Rahman et al., 2017). Previous studies estimate the overall seroprevalence of brucellosis in cattle to be 2.4%–18.4%, while the herd‐level seroprevalence in cattle was estimated as 62.5% in Bangladesh (Ahasan, Rahman, & Song, 2010; Belal & Ansari, 2013; Nahar & Ahmed, 2009; Rahman et al, 2011; Rahman et al., 2019; Sikder et al., 2012). More precisely, seroprevalence was estimated to be 5% in Chittagong, Bangladesh (Sikder et al., 2012).…”

Brucellosis is a neglected endemic zoonosis in Bangladesh and has a significant impact on public health and animal welfare of dairy farming as well as dairy farm economics. A cross‐sectional study was conducted to evaluate the seroprevalence of and risk factors for brucellosis in dairy cattle in the Chittagong metropolitan area (CMA) of Chittagong, Bangladesh. We collected serum samples (n = 158) from six randomly selected dairy farms in the CMA between February and November, 2015. The Rose Bengal Plate Test (RBPT) and a competitive ELISA (cELISA) were used as the screening and confirmatory tests respectively. Farm level and animal level demographic and risk factor data were collected using a questionnaire. The risk factors were analysed using a multivariable logistic regression with random effects. The overall seroprevalences of antibodies against brucellosis in cattle were 21.5% (34/158) and 7.6% (12/158) based on parallel and serial interpretation of the two tests respectively. Our results revealed that 20.3% (32/158) samples were positive using the RBPT and 8.9% (14/158) were positive using the cELISA. The within‐herd seroprevalence ranged from 10% to 26.3% and 5 to 20.7% using the RBPT and cELISA tests respectively. The odds of seropositivity were significantly higher in lactating cows (OR: 2.59; 95% CI: 1.02–6.55), cows producing less than 2 litres of milk (OR: 29.6; 95% CI: 4.3–353.8), cow producing 2–12 litres of milk (OR: 4.8; 95% CI: 1.1–33.4) and cows with reproductive disorders (OR: 3.2; 95% CI: 1.2–10.1). About 7.6% (12/158) and 1.3% (2/158) of cattle were found to be infected with acute and chronic brucellosis respectively. Based on these results, we suggest that cows that have reproductive disorders and are producing little milk should be prioritized for brucellosis screening in CMA. The screening tests should be used to control brucellosis in cattle in order to protect animal welfare, human health and to minimize the economic losses.

“…These findings are similar with the reports of other workers in Nigeria which associated brucellosis with sex, for examples Junaidu et al (2010), Farouk et al (2011, Kaltungo et al (2013), Adamu et al (2014, Akinseye et al (2016) and Hashimu et al (2017). In Africa and other countries Egypt (Al-Habaty et al, 2015), Sudan (Abdallah et al, 2015 and Bangladesh (Belal and Ansari, 2013). These could be due to the fact that female animals are kept for a comparatively longer period within the breeding flocks compared to male animals and so increases the risk of exposure to infections (Dinka and Chala, 2009) but it could also be due to high concentration of erythritol in the placenta and foetal fluids of female which stimulates the growth of the Brucella organisms (Radostits et al, 2004).…”

Brucellosis is an ancient and one of the world’s most widespread zoonotic diseases affecting public health and animal production. A cross-sectional study using simple random sampling was conducted between May and December, 2016 in Maigana and Birnin Gwari Agro-ecological zones of Kaduna State to determine the sero-prevalence of brucellosis in sheep. In addition the risk factors associated with sero-positivity in sheep were also assessed. A total of 400 sera samples comprised of 141 from males and 259 from females sheep were collected and screened for the presence of Brucella antibodies using Rose Bengal Plate test (RBPT) and competitive enzyme linked immunosorbent assay (cELISA). Sera analysis revealed that, 16.5% and 10.8% were seropositive to Brucella infection by RBPT and cELISA, respectively. There was statistically significant association between sex of the sheep and seropositivity to Brucella infection using RBPT (P < 0.05). Meanwhile, no statistically significant association between the age and breed of sheep and seropositivity to Brucella infection using RBPT and cELISA, respectively (P > 0.05). This study shows evidence of Brucella infection with high prevalence mainly among female sheep and the disease can be considered as a potential risk for both susceptible animals and humans in the study area. Therefore, creating awareness about brucellosis, interdisciplinary partnership and complementary effort between veterinary and public health professionals is very important to control the transmission of brucellosis.Keywords: Brucellosis, Kaduna State, Sheep, Sero-prevalence

“…Bovine brucellosis may also be responsible for retention of placenta and metritis and results in 25% reduction in milk production in infected cows (Acha and Szyfres, 2003;Anonymous, 2006). The overall seroprevalence of bovine brucellosis reported in Bangladesh is 5.3% (4.8 to 6.2) (Ahmed et al, 1992;Amin et al, 2004Amin et al, , 2005Nahar and Ahmed, 2009;Ahasan and Song, 2010;Sikder et al, 2012;Belal and Ansari, 2013;Dey et al, 2013;Islam et al, 2013) and overall prevalence of brucellosis in cows based on milk ring test (MRT) is 5.6% (4.8 to 6.3) (Pharo et al, 1981;Rahman and Rahman, 1981;Rahman et al, 1983;Sikder et al, 2012). B. abortus DNA has also been detected from bovine milk and serum samples using real time polymerase chain reaction (PCR) assays (Rahman et al, 2014(Rahman et al, , 2017 in Bangladesh.…”

The objective of this study was to detect dairy cattle infected with Brucella abortus from Jamalpur, Rangpur districts and Central Cattle Breeding and Dairy Farm (CCBDF), Savar, Dhaka in Bangladesh. Both milk and serum samples of 510 dairy cattle were initially screened by milk ring test (MRT) and Rose Bengal Test (RBT). Twelve samples positive in both MRT and RBT were further confirmed by conventional polymerase chain reaction (PCR). The overall prevalence of brucellosis based on MRT and RBT was 2.7 and 2.4%, respectively. The prevalence of brucellosis was found to be significantly (p<0.001) higher in CCBDF than Jamalpur district. Out of 7 MRT and RBT positive samples, 42.9% samples of CCBDF were PCR positive and none of the five samples of Jamalpur and Rangpur districts was PCR positive. These results strongly suggest that the use of MRT, RBT and PCR technique could lead to more reliable diagnosis of brucellosis from dairy cow in Bangladesh.
