Abstract
Brucellosis is one of the most common zoonotic diseases worldwide that is endemic to Bosnia and Herzegovina (B&H) and remains an emerging public and animal health concern in this country. Diagnostic testing of brucellosis in ruminants in B&H relies exclusively on serological methods. The present study was conducted to determine the presence of Brucella spp. in clinical samples of seropositive ruminants by Real-time PCR assay. Of the 135 samples tested, 37% were positive by Real-time PCR. The frequency of detection of Brucella-DNA in the samples collected from aborted animals (n = 20/20; 100%) was significantly higher (P < 0.00001) when compared to asymptomatic animals (n = 30/115; 26%). Among asymptomatic animals, 31.1% of cattle were positive for Brucella-DNA, followed by sheep (23.4%) and goats (16.6%). The results of this research underline the limitations of the current control policy and indicate the need for additional diagnostic methods required for more effective brucellosis control program.

Abstract
BACKGROUND Toxin-antitoxin systems (TAs) are two-component elements, which are extensive in the bacterial genome and have a regulatory role in many cellular activities including, growth arrest, survival, biofilm formation, and bacterial persistence. OBJECTIVE TAs have not well studied in Brucella spp. METHODS We evaluated the presence of different toxin-antitoxin systems, including relE- rhhlike, Fic- Phd, Cog- Rhh, and cogT- cogAT in 40 clinical Brucella melitensis isolates using PCRbased sequencing assay. RESULTS Our results showed the high presence of relE-rhh-like, Fic-Phd, Cog-rhh, and cogTcogAT s TAs genes in B. melitensis isolates that were 96.25%, 92.5%, 96.25%, and 95%, respectively. CONCLUSION A high presence of TAs genes in clinical B. melitensis isolates revealed that the TA system could be an antibacterial target in B. melitensis but more investigation is necessitated to elucidate the exact roles of these genes.

Abstract
Brucellosis is an economically important infectious disease of livestock causing abortions, infertility, delayed oestrus, interrupted lactation, increased condemnation and loss of milk production besides its zoonotic nature. The present study was conducted to compare serological assays and polymerase chain reaction (PCR) for the diagnosis of caprine brucellosis. A total of 301 whole blood samples to extract DNA for PCR and serology were collected from goats maintained at various organized herds, panjarapoles, slaughter house, local meat markets, etc. in South Gujarat region of India. Out of 301 serum samples tested, 7 samples (2.33%) were positive by all the three serological tests, viz. rose bengal plate test (RBPT), indirect ELISA (iELISA) and immunochromatographic assay (ICA). Among 301 DNA samples, genus specific PCR detected DNA of Brucella spp. in 11 samples by targeting BCSP 31 and IS-711 genes to get 223 bp and 350 bp PCR products on agarose gel electrophoresis. None of the seven serologically positive samples showed Brucella genus-specific DNA amplification by PCR and similarly all PCR positive samples were negative on serology.

Abstract
Brucellosis, one of the most common zoonotic diseases and has significant public health and economic importance worldwide. Few studies and reports have been performed to estimate the true prevalence of animal brucellosis in the Sultanate of Oman; however, no incidence of the disease was previously reported in Al Jabal Al Akhdar. The purpose of this study was to investigate the prevalence of brucellosis in goats in eight villages in Al Jebal Al Akhdar, Sultanate of Oman, namely: Al Aqaieb, Al Helailat, Al Ghilayil, Hail Al Hedap, Da'an Al Hamra, Shnoot, Al Qasha'e and Al Sarah, Al Jabal Al Akhdar in the Sultanate of Oman. In this study we used different diagnostic serological tests, namely, RBT, I-ELISA and CFT to study the prevalence of Brucella infection in goats in Al Jabal Al Akhdar. Statistical analysis using Kappa statistics was used to compare the performance of the serological tests. Biochemical tests and species-specific Multiplex PCR were used to identify the brucella species involved in the infection. A structured questionnaire and Chi-square (x2 ) statistical analysis was used to identify related brucellosis risk factors. This study is the first to reveal brucellosis infection in goats in eight villages in Al Jebal Al Akhdar, Sultanate of Oman, namely: Al Aqaieb, Al Helailat, Al Ghilayil, Hail Al Hedap, Da'an Al Hamra, Shnoot, Al Qasha'e and Al Sarah, with an overall seroprevalence of 11.1%. The study also compared the performance of three different serological tests, namely, RBT, I-ELISA and CFT. Statistical analysis using Kappa statistics showed that the degree of agreement was best seen between RBT and CFT (96%), followed by RBT, I- ELISA (91.4%) and CFT and I- ELISA (89.2%). Biochemical tests and species-specific Multiplex PCR showed the typical profile for B. melitensis. A structured questionnaire and Chi-square (x2 ) statistical analysis indicated that the presence of abortion is the major risk factor for the prevalence of brucellosis, whereas age and sex were not significant factors in the tested animals. Besides, poor knowledge about brucellosis, consumption of unpasteurized milk or milk products, free trade of animals and the introduction of new animal breeds to herds were all contributing risk factors to the prevalence of brucellosis. The prevalence of human brucellosis obtained verbally from pastoralists gave an insight that brucellosis could pose a public health hazard, especially in those high-risk groups, mainly the pastoralists in the study area. Because of their constant and increasing interaction with their animals, pastoralists could be at a high risk of occupational infection.

Abstract
The collection of serum samples from cows is frequently difficult to implement in large-scale surveys, and may involve a high risk of occupational infection. This study assessed the potential of using raw milk sampling as a suitable method for use in a pilot survey of Brucella abortus infection status in cattle. Raw milk samples from 816 cows were examined. Polymerase chain reaction assays of raw milk, with primers derived from the IS711 element of the Brucella genome, were used. Of the cows, 55 were Brucella positive based on serum agglutination test (SAT) results. Polymerase chain reaction amplified Brucella DNA in 25 (45%) of the 55 SAT-positive cows. All of the 689 SAT-negative cows were found to be negative in PCR assays of their milk. Brucella infection status based on PCR results was then predicted for 72 cows from private h erds in which the brucellosis status was unknown. Subsequently, SAT verification of Brucella status was performed. There was no significant difference between predicted and actual SAT-positive rates in those 72 cows. This study indicates a relationship between Brucella detection levels obtained using milk-based PCR results and SAT results. The specific, rapid, and easy sampling procedure within milk-based PCR assaying for brucellosis detection makes the milk PCR method an attractive alternative for evaluation of B. abortus infection in cows, particularly if used as a routine screening and surveillance tool to reduce brucellosis outbreaks.

Abstract
The aim of this study was to standardize and evaluate a PCR assay for the detection of Brucella canis (B. canis) in lymph node samples of naturally infected dogs. The performance of the PCR was compared with the results of bacteriological culture as reference method. Forty-eight inguinal lymph node samples were collected from 48 dogs (18 males and 30 females) that died in the city's pound in the years 2007-2008 and were examined by microbiological culture and the PCR assay. B. canis was isolated from 4 (8.3%) of 48 lymph node samples. Forty-four (91.7%) of the samples were bacteriological culture negative. B. canis DNA was directly detected from all culture positive lymph node samples (n = 4) by PCR. All of the culture negative samples were confirmed as negative by PCR. When the culture method was used as a gold standard, sensitivity and specificity of the PCR assay were found to be 100%. The limit of PCR detection of B. canis DNA was 1.4 x 10(1) CFU/g at least. In conclusion, the PCR assay has been shown to have a diagnostic performance equal to bacteriological culture for detection of B. canis. By a non-hazardous protocol for laboratory workers, the assay can be performed in one day.
