In the present study, the incidence of bovine tubeculosis (bTB) and brucellosis in Hanwoo (Korean native cattle) and dairy cow in Gyeongsangnam-do was investigated for three years from 2020 to 2022. The incidence bTB tested by tuberculin skin test with purified protein derivative (PPD) and gamma interferon (γ-INF) test with a commercial enzyme-linked immunosorbent assay. From 2020 to 2022, the incidence of bTB showed a decreasing trend in Hanwoo, while an increasing trend in dairy cow. In the case of Brucellosis, the positive rates for Hanwooe gradually increased. However, no brucellosis was found in dairy cow from 2020 to 2022. The increase in the incidence of these diseases is presumed to be related the small scale and poor sanitation facilities of livestock farms in Gyeongsangnam-do, and easy access of wild animals. Therefore, in order to suppress the incidence of the diseases, it is necessary to the farm scale from small to large and to strengthen sanitary facilities on farms.

This survey was conducted for the serological confirmation on large outbreak of bovine brucellosis in two dairy farms. Serological tests were performed by the plate agglutination test, tube agglutination test, enzyme linked immunosorbent assay(ELISA), complement fixation, ,test(CFT) and rose bengal plate test(RBPT). Total 200 heads(134 heads in farm A and 66 heads in farm B) were tested. The primigravida and positive group have been raised separately in the farm A and both group have been raised together in the farm B.. The result were summarized as follows ; 1. Positive ratios in positive herds of farms by the tube agglutination test were 68.3% in farm A and 53.2% in farm B. 2. Seroconversion to brucella was observed in the primigravidas group in farm B, but was not observed in the primigravidas group in farm A. 3. All calves born in positive herd were serologically negative at time of test. 4. Positive ratio of ELISA in farm A was higher than that of tube agglutination test. 5. Number of positive reactors by the CFT, RBPT in farm A were equal to those of tube agglutination test.

In order to investigate serum antibodies for detection of brucellosis in pigs, a total of 1208 sera were tested by Rose Bengal test (RBT), the standard tube agglutination test (STAT) and competitive ELISA (cELISA). The sera were collected from pigs of Gyeonggi, Chungnam, Chungbuk, Jeonnam and Jeonbuk, provinces during the period 2002 to 2004. All the sera were screened by RBT, and were confirmed by STAT and cELISA. Among 1208 sera, 26 sera (2.2%) were positive in screening test. All the 26 positive sera were positive by STAT, while all the sera were negative by cELISA. On the basis of this study, farmed pigs may be exposed to Brucella species. Furthermore, these results suggest that establishment of diagnoses for detection of porcine brucellosis is necessary.

This study was conducted to examine the utilization of immunohistochemistry using the bovine anti-brucella immunoglobulin G (IgG) antibody in the diagnosis of brucellosis and to develop a functional biomarker relation for the progress of the disease. Anti-brucella IgG antibody was purified from the affected bovine serum using an affinity chromatography. We performed our investigation on 17 cases of brucellosis and 19 control cases with negative Rose-Bengal test results. Our purified anti-brucella IgG antibody showed a positive immunoreactivity in cytoplasmic hepatocytes of the centrilobular region, and glomeruli and tubular epithelium of the kidney. The protein pattern of the affected liver versus control was analyzed by two-dimensional electrophoresis, showing a different expression pattern of proteins between the two. Five protein spots were up-regulated and another were five down-regulated in the brucellosis liver. Significant upregulaton of catalase and 3-hydroxyacyl-CoA dehydrogenase might be due to a compensatory reaction in response to the endotoxic shock of brucella. In conclusion, the anti-brucella IgG antibody may be a good tool for discriminative diagnosis of the affected tissues and proteomics data suggest new target proteins underlying a possible pathogenic mechanism of brucellosis.

The incidence of Brucellosis is increasing in Korea. Spondylitis is the most frequent complication, but it is difficult to diagnose because its clinical symptoms are non-specific. It should therefore be included in the differential diagnosis of back pain. We report three rare cases of brucellar spondylitis successfully treated by medical and surgical therapy.

Brucellosis, a zoonosis with worldwide distribution, is a systemic infection caused by facultative intracellular bacteria of the genus Brucella, which can involve multiple organs and tissues. We report an uncommon case of spondylodiscitis with epidural abscess due to Brucella in a male stockbreeder. Diagnosis was based on clinical history, and supported by Brucella serology and magnetic resonance imaging. Clinical and radiological improvement were observed with a combined antimicrobial therapy of doxycycline, rifampicin, and gentamycin.

Brucella spp. are small, non-motile Gram-negative coccobacilli known to cause disease in a number of vertebrate species including humans and brucellosis is one of the world's major zoonoses, alongside bovine tuberculosis and rabies. There are about 33.55 million goats and 1.16 million sheep in Bangladesh. The sheep and goats can significantly play an important role in the economic well being of the resource-poor farmer in Bangladesh. Sexually matured 362 female small ruminants(300 goats and 62 sheep) were examined. Approximately 3-5 ml of blood was collected from the jugular vein of each animal and sera samples were prepared. Samples were then tested for brucellosis by using Rose Bengal test(RBT), plate agglutination test(PAT) and tube agglutination test(TAT). Among 362 small ruminants, irrespective of species(sheep or goat), diagnosed highest in TAT, 2.21%(n=8) and lowest both by RBT & PAT, 1.93%(n=7) and it is concluded that TAT is superior than RBT and PAT.

A total of 710 bovine serum samples which are composed 532 bovine serum samples showed negative reaction and 178 bovine serum samples showed positive reaction with tube agglutination test (TAT) from North area of Gyeong-nam, Korea were tested using all the 3 assays which are Rose-Bengal test(RBT), tube agglutination test (TAT) and enzyme-linked immunosorbent assay (ELISA, two types) and analyzed for evaluation of specificity, sensitivity, reproducibility and predictive value. In the comparison of serum antibody titer agglutination test, RBT showed almost agreement with TAT. In the comparison of TAT and two types of ELISA method, they showed difference in specificity and sensitivity about 5%. But there is no significant difference in detecting sensitivity between two types of ELISA method and TAT. In serologic tests for bovine brucellosis, the new assay ELISA would be a good candidate for serologic survey for bovine brucellosis in Korea because it is efficient in detecting many test samples quickly. But the serum agglutination tests (RBT, TAT) are more economical and easy assay for detection. In the test of comparison of antibody titer between first day of finding and 10 days after finding by TAT, there was no change in 55% (76/139) of positive cattle.
