Live attenuated vaccines are essential elements in control programs for the prevention of brucellosis. Here, we report the whole-genome sequence of the original Elberg Brucella melitensis Rev.1 vaccine strain, passage 101 (1970). Commercial lines of the original strain have been successfully used in small ruminants worldwide.

We report the draft genome sequences of two Brucella abortus strains LMN1 and LMN2 isolated from cattle and pig. The LMN1 and LMN2 have the genome size of 3,395,952 bp and 3,334,792 bp, respectively. In addition to the conserved genes of Brucella, few novel regions showing similarity to the phages were identified in both strains.

Brucella broth without supplementation is the recommended medium for broth microdilution susceptibility tests of Brucella abortus, B. melitensis, and B. suis. Based on an eight-laboratory collaborative study using a pH-adjusted modification of this medium, we propose MIC quality control ranges for three control strains against 10 antimicrobials that are potentially efficacious for treating infe...

Brucellosis is a zoonotic disease caused by bacteria of the genus Brucella The disease is endemic in many areas, causing chronic infections responsible for reproductive disorders in infected animals. Here, we present eight complete genome assemblies of eight Brucella abortus strains isolated from water buffaloes farmed in the Campania region.

A new method was developed based on SPR for the detection of Brucella abortus CE. The detection limit of SPR biosensor was found to be 0.1 ppm. Interference study was also performed with Brucella CSP-31 and a decrease in angle change was observed with exemplifying specificity for antigenantibody interaction.

Brucellosis, which is among the most widespread global zoonotic diseases, is endemic in the nation of Georgia and causes substantial human morbidity and economic loss. Here, we report whole-genome sequences of three Brucella melitensis and seven Brucella abortus isolates from cattle, sheep, and humans that represent genetic groups discovered in Georgia.

INTRODUCTION Brucellosis is one of the most important zoonotic diseases that affects multiple livestock species and causes great economic losses. The highly conserved genomes of Brucella, with > 90% homology among species, makes it important to study the genetic diversity circulating in the country. METHODOLOGY A total of 26 Brucella spp. (4 reference strains and 22 field isolates) and 1 B. m...

Large-scale genomic rearrangements including inversions, deletions, and duplications are significant in bacterial evolution. The recently completed Brucella melitensis 16M and Brucella suis 1330 genomes have facilitated the investigation of such events in the Brucella spp. Suppressive subtractive hybridization (SSH) was employed in identifying genomic differences between B. melitensis 16M and B...

A rough (R) Brucella abortus 45/20 mutant was more sensitive to the bactericidal activity of polymyxin B and lactoferricin B than was its smooth (S) counterpart but considerably more resistant than Salmonella montevideo. The outer membrane (OM) and isolated lipopolysaccharide (LPS) of S. montevideo showed a higher affinity for these cationic peptides than did the corresponding B. abortus OM and...
