“…(Nielsen et al 2004). The observed brucellosis seroprevalence results agree with those of previous studies in Zimbabwe (Madsen, 1989;Mohan et al 1996) and those from smallholder farming areas in other regions (Bayemi et al 2009;Ibrahim et al 2010;Karimuribo et al 2007). However, higher brucellosis seroprevalence have been recorded in individual cattle from traditional smallholder herds in other areas (Chimana et al 2010;Faye et al 2005;Muma et al 2006).…”

“…The fact that brucellosis was low in areas with small median herd sizes showed that the risk of transmission of Brucella spp. among cattle was low in small herds (Ibrahim et al 2010). However, the observed results for Gokwe may be contributed by a high proportion of farms that shared facilities for grazing and watering of cattle compared to the other study areas which kept their herds as self-contained units (data not shown).…”

Seroprevalence of brucellosis and its risk factors in cattle from smallholder dairy farms in Zimbabwe. Tropical Animal Health and Production, 43:975-979. 2 AbstractA cross sectional study was conducted to investigate seroprevalence of brucellosis and the associated risk factors in cattle from smallholder dairy farms in Gokwe, Marirangwe, Mushagashe, Nharira, Rusitu and Wedza areas of Zimbabwe. A total of 1440 cattle from 203 herds were tested serially for Brucella antibodies using Rose Bengal test (RBT) and the competitive ELISA (c-ELISA). Weighted seroprevalence estimates were calculated and risk factors in individual cattle investigated using logistic regression analysis. The overall individual animal brucellosis seroprevalence was low, with mean of 5.6 % (95 % CI: 4.4 %, 6.8 %). Gokwe had the highest individual (12.6%; 95 % CI: 3.9 %, 21.4 %) and herd-level (40.0%; 95 % CI: 22.1%, 58.0 %), while Wedza had the lowest individual (2.3 %; 95 % CI: 0 %, 5.3 %) and herdlevel (8.0%; 95% CI: 0.0 %, 18.9 %) brucellosis seroprevalence, respectively. In individual cattle, the area of origin, age and history of abortion were independently associated with brucellosis seroprevalence. While the seroprevalence was independent of sex, it decreased with increasing age. Cattle 2-4 years old had higher odds (OR = 3.2; 95 % CI: 1.1, 9.1) of being seropositive compared to those > 7 years. Cows with a history of abortion were more likely to be seropositive (OR= 7.9; 95 % CI: 3.1, 20.1) than controls. In conclusion, the area-to area variation of brucellosis may be linked to ecological factors and differences in management practices. The implementation of stamping out policy, bleeding and testing animals before movement and promoting the use self-contained units are likely to significantly reduce the public health risks associated with Brucella infections in cattle.

“…Perusal of the literature indicated prevalence of brucellosis in western region (Gujarat state) was ranging from 8.98 to 44.00% (Sutariya et al 2005;Chauhan et al 2000), 17% in southern region (Isloor et al 1998), 6.3% in central region (Madhya Pradesh state) (Mehra et al 2000) and 12.9% in northern region (Punjab state) (Dhand et al 2005). In other countries, sero-prevalence of brucellosis was reported to be 3.1% in Ethiopia (Ibrahim et al 2009), 6.5% in Jordan (Al-Majali et al 2009), 8.4% in Cameroon (Bayemi et al 2009) and 32.92 to 39.45% in Turkey (Sahin et al 2008).…”

This study was carried out to investigate the prevalence of bovine brucellosis and infectious bovine rhinotracheitis (IBR) in organized dairy farms with history of abortion in India. ELISA and Rose Bengal Plate Test (RBPT) were used to detect the seropositive animals and the test results indicated that 22.18% and 13.78% animals were declared as sero-positive by ELISA and RBPT, respectively. Milk Ring Test (MRT) was carried out only in one farm and 12.82% of the tested animals were turned positive. Culture examination analysis of milk samples, two animals revealed the presence of organisms indistinguishable from Brucella spp. The organism was confirmed as brucella by morphological characteristics and biochemical tests. An overall sero-prevalence of antibodies against IBR was found to be 60.84%. None of the genital and nasal swab samples was found to be positive for presence of bovine herpesvirus -1 (BHV-1) on repeated passage in Madin-Darby Bovine Kidney (MDBK) cell lines. Brucella and IBR considered as the causal agent for abortions in these farms. The present study indicates the urgent need and the necessity for control of these infectious diseases which cause heavy economic losses to the organized farms.

“…Since the first report of brucellosis in the 1970s in Ethiopia, the disease has been noted as one of the important livestock diseases in the country (Asfaw, 1998;Eshetu et al, 2005;Kebede et al, 2008;Ibrahim et al, 2010). Prevalence of bovine brucellosis varies widely across Ethiopia, with reported seroprevalences ranging from 0.2% in south-western Ethiopia (Tolosa, 2004) to 38% in western Ethiopia (Rashid, 1993).…”

A cross-sectional study was conducted in Asella and Bishoftu towns of Oromia Regional State of Ethiopia to determine seropositivity and associated risk factors exposing dairy cattle to brucellosis from December, 2013 to March, 2014. A total of 570 dairy cattle from 35 herds were purposely selected for inclusion in the study based on abortion history. From 35 farms studied, 80, 55.56 and 100% of the farm owners in small, medium and large herd sizes responded as they were aware of brucellosis, respectively. It was also found out that all farm owners of the study area were dependent on culling of the known Brucella infected animals, while most of the farm owners dispose the after birth to open dump in small and medium herd size farms. All sera sample collected were tested and confirmed serologically using the card test (CT), rose Bengal plate test (RBPT), indirect enzyme linked immuno sorbent assay (i-ELISA) and complement fixation test (CFT). Out of 570 samples tested in the present study, an overall sero prevalence was estimated 1.4% (95% CI: 0.241, 3.461) by complement fixation test (CFT). Among the tested samples, 13 (2.28%), 15 (2.63%) and 16 (2.81%) were found positive by the aforementioned tests, respectively. The higher seroprevalence, 3.23% (95% CI: 3.0, 7.4) was observed in Asella compared to Bishoftu (0.52%) town. A Chi-square computed statistical analysis indicated that origin (χ2=6.63; P<0.05), breed type (χ2= 8.49; P<0.05), abortion history (χ2=92.43; P<0.001) and abortion period (χ2=192.97; P<0.001) were the major risk factors for Brucella infection in the study areas. Multivariable logistic regression statistical analysis revealed that origin and breed type were significantly associated with Brucella seropositivity (P<0.05). Consequently, origin was statistically identified to be the major risk factor for brucellosis to occur in relation to other factors (OR=7.56). In conclusion, the prevailing Brucella seropositivity in most of the dairy farms of the study areas signifies the economic importance of brucellosis in the dairy cattle industry and the potential public health implication for human population. Therefore, more proactive measures should be taken to protect the cattle populations from Brucella infection to reduce its economic impact to the dairy industry and the risk of zoonotic infection in exposed human population in the study areas.
