An investigation was carried out to detect anti-Brucella antibodies of sheep in Al-Anbar province by using few serological tests; rose Bengal plate test (RBPT) and tube agglutination test (TAT). A total of 754 sheep blood samples (94 Ram and 660 Ewe) were collected randomly distributed in Al-Anbar province from unvaccinated sheep flocks with different ages. A total percentage of infected sheep depending on RBPT was 10.21% with significant differences at (P< 0.01), it was 9.69% in ewes, whereas in rams it elevated to reach 13.82%, in addition to the disease was higher seroprevalence at > 3 years (12.78%) in both gender with significant differences at (P<0.05) than lower ages. Out of 77 RBPT positive sera, 38(49.35%) were positive using TAT, there was 14 seropositive with significant differences at (P< 0.01). The study reported that brucellosis was distributed in Al-Anbar province with variable percent (3.26% to 21.27%), as well as emphasized on different epidemiological aspects.

     A research was carried out to detect Brucella antibodies of sheep and goats in Al-Sulaimanya governorate by using modified Rose Bengal test and indirect ELISA. A total of three hundred and eleven (311) whole blood samples (160 sheep and 151 goats) were collected randomly from eight different regions in Al-Sulaimanya governorate from unvaccinated flock with different ages. A total percentages of positive result by using modified Rose Bengal test was 14.46% (20% in sheep and 8.6% in goats), while by using indirect ELISA was 27.6% (35.2% in sheep and 19.2% in goats) with significant (P<0.05) differences. It revealed that rates to modified Rose Bengal test were 14.34% in female and 10.09% in males while to indirect ELISA 26.35% in female and 33.9% in males in sheep and goats, In conclusion of this study the high seroprevelence was at 1-3 years 19.2% and ˃3 years 33.96% according to modified Rose Bengal test and indirect ELISA, respectively.

SummaryA total of 1887 bovine sera positive to the Rose Bengal plate test were subjected to other serological tests for bovine brucellosis: the complement fixation test using warm fixation (CFTW), the serum agglutination test (SAT) and the radioimmunoassay (RIA).The SAT was generally much less sensitive than the CFTW. Many sera, however, gave positive reactions in the SAT but no reaction in the CFTW or the RIA. These SAT reactions were attributed to IgM antibody.Comparison between the results of the CFTW and the RIA led to the conclusion that 200 ng could be used as a minimum diagnostic reaction in the RIA.

SUMMARYBrucella-specific antibodies of different immunoglobulin classes were quantitatively evaluated with respect to their efficiency in serological tests for bovine brucellosis.IgM reacted more efficiently than IgG1and IgG2in both the Rose Bengal plate test and serum agglutination test. The complement fixation test was found to be slightly more sensitive to IgM than to IgG1and did not react to IgG2.IgM was, however, partly inactivated when heated at 60°C. in the presence of serum.

Brucellosis is an infectious debilitating, acute or sub-acute febrile illness usually marked by an intermittent or remittent fever accompanied by malaise, anorexia and prostration, and which, in the absence of specific treatment, may persist for weeks or months. The aim of this study was to determine the relationship between Socio-Demography Characteristics and prevalence of brucellosis among community members in Kenya. A case of Mandera East Sub-county, Mandera County, Kenya. The study was descriptive cross sectional study which collected both qualitative and quantitative data from where a sample of 420 respondents was systematically selected from heads of 2,617 households form Mandera East Sub-county. The study instruments included questionnaire, Focus Group Discussion guide and Interview Guide. Blood samples were screened for brucellosis using Rose Bengal Plate Test (RBPT) and the positive sera were subjected through Serum Slow Agglutination Test (SSAT) which acted as a confirmatory test. Data was analyzed using SPSS Version 20 and results of the study presented in frequencies and percentages in Tables and Figures. Ethical issues were observed and consent sought from the respondents. Rose Bengal Plate Test (RBPT) indicated a prevalence of 24.8% (95% CI: 20.0–29.6) and Serum Slow Agglutination Test (SSAT) indicated that the prevalence was at 14.3% (95% CI: 8.7–19.9) among the respondents. The study showed that the seroprevalence was higher among the male respondents (98%; n=103) as detected through RBPT and (98%; n=57) confirmed through SSAT. There was significant relationship between the gender and seroprevalence as tested through RBPT (P<0.001).

An investigation was carried out to study the seroprevalence and risk factors for Brucella seropositivity in sheep in Bangladesh. For this, highly sheep populated ten different districts including all seven divisions of Bangladesh were selected where sheep of Panchagarh (151), Naogaon (101), Tangail (83), Noakhali (56), Sunamganj (52), Patuakhali (119) and Dhaka (75) were tested but sheep of Chapai Nawabganj, Khulna, Noakhali and Feni has under tested for Brucellosis. In the present study, seroprevalence of ovine brucellosis was tested by Rose Bengal Plate Test (RBPT), Serum Agglutination Test (SAT) and Enzyme-Linked Immunosorbent Assay (ELISA). About 5% sheep might have got Brucella infection. The highest Brucella antibody was observed in sheep of Tangail district (8.4%) followed by the sheep of Savar (8.0%), where as sheep of Subarna Char and Kala Para were free from Brucella antibody. In relation to age and sex, adults (6.5%) were more positive than young (3.6%) and female (5.3%) were more susceptible than male (3.8%).Asian J. Med. Biol. Res. March 2016, 2(1): 13-18

The Rose Bengal plate agglutination test (RBT) was evaluated for the diagnosis of equine glanders, and its diagnostic efficiency was compared with that of mallein and other serological tests, including indirect hemagglutination test (IHAT), complement fixation test (CFT), and modified counter immunoelectrophoresis test (mCIET). Sera from 70 naturally infected culture-positive, 96 potentially exposed cohorts, and 110 healthy equines were tested. All tests but mCIET showed 100% specificity when testing the sera from glanders-negative equines. The calculated sensitivities of RBT, IHAT, CFT, mCIET, and mallein test when testing culture-positive equines were 90.0, 97.1, 91.4, 81.4, and 75.7%, respectively. The RBT was significantly ( P < 0.05) more sensitive than the mallein test and mCIET. The positive and negative predictive values of each test (RBT, IHAT, CFT, mallein test, and mCIET) were as follows: 100 and 94, 100 and 98.2, 100 and 96.7, 100 and 86.6, and 90.5 and 88.6, respectively. On comparing glandered and nonglandered animals, the highest agreement (0.987) was found between RBT and CFT followed by RBT and IHAT (0.940), RBT and mallein test (0.871), and RBT and mCIET (0.852). Because the RBT is simpler and rapid to perform, the inclusion of the test as a supplementary test for the diagnosis of glanders in field conditions is recommended.
