“…In the current study, buffaloes aged more than 4 years had higher prevalence (24.44%) than other age groups, and the animals that experienced abortion showed the highest prevalence of brucellosis. Similar observations were also recorded by Vikrant et al (2006) and Islam et al (2013). Age-wise prevalence has also been studied by Abubakar et al (2010) who showed that the incidence of brucellosis increased with age, and the incidence is high in sexually mature animals.…”

Brucellosis is considered an economically important highly contagious and zoonotic bacterial disease of water buffaloes. Control of brucellosis in buffaloes is very important for public health. The efficacy of control program depends on the detection and eradication of infected animals coupled with vaccination and application of biosecurity. This study was carried out to control the brucellosis in buffalo farm in Assuit Governorate, Egypt during the period from April 2015 to August 2016. Out of 620 unvaccinated buffaloes, 87 (14.03%) aborted. Moreover, 90/620(14.51%), 82/620(13.22%), 82/620(13.22%), and 80/620 (12.9%) buffaloes were serologically positive by BAPA, RBPT, m SAT and Riv.T, respectively. Three isolates were differentiated as Brucella melitensis, biovar 3, one strain isolated from one vaginal swap out of 10 Riv.T. positive recently aborted buffaloes (10%) and two strains were isolated out of ten milk samples of Riv.T. positive buffaloes (20%). Eighty serological positive buffaloes to Riv.T were culled from the herd, while 60 serological negative heifers were vaccinated by Brucella abortus S 19 vaccine, with a dose of 3-8×109 cfu/5ml and monitored for serological titer for 240 days. After 6 months of vaccination, the number of serologically positive calves declined marginally to 50 (83.33%), 40 (66.67%), 50 (83.33%), 0 (0%), 40 (66.67%) and 0 (0%) by BAPA, RBPT, mSAT, CFT, iELISA and cELISA, respectively. Three successive serological tests every three weeks were done by screening tests, BAPA and RBPT and confirmed by Riv.T. At the end of the control program, all examined buffaloes were serologically negative. Application of biosecurity in the farm was applied by the sanitary disposal of aborted material and application of proper disinfectants at its recommended work strength and contact time.

“…In Bangladesh, it was first reported in cattle in 1967 [ 10 ] and in human in 1983 [ 11 ]. Several studies were carried out in Bangladesh to record the seroprevalence of brucellosis in cattle and buffaloes [ 12 – 14 ]. Brucella abortus has been identified by a real-time PCR assay directly from clinical specimens [ 15 – 17 ].…”

Brucellosis is endemic in Bangladesh both in humans and in animals. A number of reasons complicate the diagnosis, as bovine brucellosis can be diagnosed by various serological tests. But the tests have a limitation; when the organism remains intracellular, the disease goes into chronic stage and the antibody titres may decline. The present study was conducted for isolation and detection of Brucella spp. by polymerase chain reaction (PCR) from seronegative cows. A total of 360 dairy cows from three geographical regions were screened serologically by Rose Bengal Plate Test (RBPT) where 24 samples were serologically positive and the rest of the samples were serologically negative. Among the 24 seropositive individuals, 11 were culture positive and 6 were culture positive from serologically negative dairy cows. The overall seroprevalence of brucellosis in cattle was 6.6% and in disease condition a higher prevalence was recorded in abortion (28.07%) followed by infertility (13.33%). To confirm the Brucella spp. in seronegative dairy cattle, the isolates were extracted and PCR was conducted, which produced 905 bp amplicon size of 6 Brucella spp. from milk sample. So, for the detection or eradication of brucellosis, a bacteriological test and a PCR technique should be performed with the serological test of milk.

“…Application of strict hygienic measures on the farm, proper disposal of aborted material, regular serological monitoring of brucellosis in animals on farms and use of vaccine are some of the important preventive measures against brucellosis in sheep and goat (Islam et al, 2013). Handling of aborted materials using protective clothing and gloves, drinking of properly boiled milk and consumption of meat from brucellosis free sheep and goat could reduce the risk of transmission of brucellosis from sheep and goat to human (Corbel, 1997).…”

“…Brucellosis is a worldwide emerging zoonotic disease caused by Gram negative bacteria belongs to the genus Brucella (Islam et al, 2013). It mainly affects the reproductive tract of animals and responsible for huge economic losses in livestock sector due to abortion, infertility, still birth, retention of placenta and decreased milk production (Radostits et al, 2007).…”

A cross sectional study was performed to determine the seroprevalence and risk factors of brucellosis in sheep and goat on the farms, Veterinary Teaching Hospital of Bangladesh Agricultural University (BAU), and animal slaughter house of Mymensingh , Bangladesh. Sera were prepared after collecting blood samples from sheep (n=101) and goat (n=113). Risk factors relating to brucellosis were determined considering the variables generated from a questionnaire. These variables included animal's age, sex, pregnancy, and husbandry system. The sera were tested by Rose Bengal Plate Test (RBPT) for the detection of Brucella abortus specific antibodies in sheep and goat. The results revealed that 5.94% (n=6/101) sera of sheep, and 6.19% (n=7/113) sera of goat were positive for brucellosis. Higher prevalence of brucellosis was recorded in female sheep (7.54%) and goat (6.49%) as compared to male sheep (4.16%) and goat (5.50%), respectively. The s heep and goat above two years of age showed higher prevalence of brucellosis (8.69% and 6.45%) as compared to other ages. No risk factor was found to be statistically significant (p>0.05). Data of this study suggest that sheep and goat could be the reservoir hosts of brucellosis that might constitute a hurdle in the controlling of bovine and human brucellosis.
