“…Brucellosis is not a notifiable disease in Bangladesh and was first serologically investigated in goat (1983) Rahman et al, 2009Rahman et al, , 2010Rahman et al, , 2011Ahasan et al, 2010;Muhammad et al, 2010). A variable seroprevalence ranged from 1.0 to 6.2% were reported Islam et al, 2010;Rahman et al, 2011a;Akhter et al, 2014). Exceptionally higher seroprevalence (14.5%) was reported in just one study in goat (Rahman et al, 1988).…”

Background: Brucellosis is one of the ancient re-emerging zoonotic diseases which play a significant economic impact on public health and livestock sector. Many studies were carried out on the epidemiology of the disease recently but economic importance was not focused on those studies. This study was conducted to determine the true prevalence and economic impact of caprine and ovine brucellosis in Mymensingh district, Bangladesh. Methods: A cross-sectional epidemiologic study covering all upazilas of Mymensingh district, Bangladesh was conducted during the period from January to December, 2016. The data related to age, sex, abortion record and reproduction disorders were also collected on the sampling day using a questionnaire. Blood samples ( n=2593) were collected from randomly selected native goat and sheep where Rose Bengal Test, Rapid Brucella AB test kit and MAb-ELISA (Monoclonal antibody based blocking Enzyme-Linked Immunosorbent Assay) were used to identify the positive reactors. Results: The prevalence of caprine and ovine brucellosis was estimated to be 1.6% whereas it was found to be 1.56% and 1.64 % in goats and sheep respectively. The prevalence data was incorporated to the economic model to quantify the financial loss due to brucellosis. The total losses attributed to the disease was 48436400 taka (605455 US$) annually in the district whereas 46462900 taka (580786.25 US$) and 1973500 taka (24668.75 US$) in goat and sheep respectively. Conclusions: The study concluded that brucellosis silently constitutes economic loss to the economy of the country and the producers due to insufficient knowledge and inadequate diagnostic facilities, lack of awareness and an effective prevention and control strategy.

“…Exceptionally higher seroprevalence (14.5%) was reported in just one study in goat (Rahman et al, 1988). The prevalence recorded in sheep were 1.2% to 9.8% Rahman et al, 2011a,b;Ahsan et al, 2014;Akhter et al, 2014) of which highest prevalence (9.8%) was recorded in Mymensingh and Netrokona regions (Ahsan et al, 2014;Akhter et al, 2014).…”

“…Results of this investigation was in accordance to that observed by Rahman et al (2011a). However, it contradicted with Akhter et al (2014) who found that none of these risk factors was associated with brucellosis in sheep. Contradiction in the previous reports may be attributed to variation in the risk factors in terms of sex, age, district, breed, stillbirth and neonatal losses at both individual animal and flock level (Gebremedhin, 2015;Akhter et al, 2014).…”

In this work, the prevalence of Brucella spp. antibodies among sheep in Aljouf region, Saudi Arabia was investigated. Five hundred and fifty sera were collected randomly during March to April 2021 from sheep of both sexes, age and breed in the region. Samples were tested for circulating antibodies against Brucella spp. by Rose Bengal Plate Test (RBPT), Rapid test (RT) and ELISA. Pearson's Chi-square was adopted to estimate possible correlation between RBPT, Rapid test, ELISA and risk factors involved. Kappa test was used to measure agreement of the results and the tests adopted. Out of the tested sera forty (7.3%) were positive for Brucella spp. antibodies by RBPT, 23 (18.4%) in Dumataljundal, 16 (16.7%) among male, compare to 24 (5.3%) among female, 28 (70%) were positive among the groups of 12-30 month age. On the other hand, eighty-eight (16%) sera were positive in Brucella ssp. Antibodies by rapid test, 39 (31.2%) in Dumataljundal, 23 (24.0%) among male, compared to 65 (14.3%) in female, higher percentage (20.7%) of antibodies was found in 36-48 months old. ELISA revealed that eighty-five samples (15.5%) were positive by ELISA, 39 (31.2%) in Dumataljundal, 23 (24%) among male, compared to 62 (13.7%) in female, higher percentage (19.8%) of Burucella spp. antibodies was found in 36-48 month age. Significant correlation between seroprevalence screened by RBPT and city (-0.168), sex (-0.166) and age (0.121) were recorded. Likewise, significant relationship between seropositivity detected by rapid test and city (-0.311), sex (-0.100) and age (0.088) were estimated. ELISA results were correlated with city (-0.297), sex (-0.108) and age (0.085). Analysis revealed strong correlation between ELISA and rapid test (0.980), moderate correlation (0.636) between ELISA and RBPT was noticed. Kappa test indicated moderate agreement between RBPT and ELISA (value=.583), while perfect agreement between rapid test and ELISA was estimated (value=.979). Large-scale epidemiological investigation is needed to better understand possible risk factors involved and to implement effective control measures.

“…B. melitensis , the etiological agent of brucellosis in goats, is a zoonotic infection and is most pathogenic for humans. Higher seroprevalence was recorded in female goats compared to male [ 41 , 42 ], providing a potential reservoir for the organism to propagate. A report from Egypt revealed that in each year the incidence of Brucella infection among slaughtered goats was found to be more compared to other species such as buffalo, sheep, and cattle [ 43 ].…”

Aim:The aim of the present study was to investigate the molecular etiopathology of occurrence of reproductive diseases in female goats. Reproductive diseases in goats account for major economic losses to goat farmers in terms of valuable loss of offspring and animal productivity.Materials and Methods:A total of 660 female genitalia were examined for pathological conditions (macroscopic and microscopic lesions). The etiopathological study was carried out for the presence of pathogenic organisms such as Brucella, Chlamydia, and Campylobacter in the uterus and ovary. Based on the microscopic lesions, suspected samples were subjected to diagnostic polymerase chain reaction (PCR) for various etiological agents employing 16srRNA genus specific primers for Campylobacter and Chlamydophila and OMP31 gene-based PCR for Brucella melitensis and nested PCR using ITS-1 gene primers for Toxoplasma gondii. For Brucella suspected samples, immunohistochemistry (IHC) was also performed.Results:In studied female genitalia, 108 (16.30%) showed gross abnormalities with overall 23.32% occurrence of pathological conditions (macroscopic and microscopic lesions). Pathological involvement of the uterus was the highest 68 (62.96%), followed by the ovaries 27 (25%) and other organs. Major uterine condition observed was endometritis (5.60%). In uterine infections, 35 (5.30%) samples were found positive for Campylobacter spp., 12 (1.81%) samples for B. melitensis, and 3 (0.45%) samples were positive for Chlamydophila spp. Among the samples positive for B. melitensis by PCR, 3 were found positive by IHC also. Corynebacterium ovis was detected by PCR using specific primers in a case of hydrosalpinx. It was concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats.Conclusion:The present study concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats.
