Abstract. The genus Brucella historically has been classified in the family Brucellaceae, but it was recently removed from this family and placed with several other genera in a group of unaffiliated Gram-negative aerobes. Members of this genus are important bacteria because of the widespread and serious nature of the disease they can cause in both man and :// Title: The Use of Phages for the Removal of Infectious Biofilms VOLUME: 9 ISSUE: 4 Author(s):J.

Keywords:Biofilms, Phages, antibiotic therapies, exopolymeric matrix, polysaccharide lyase, immune system
The current study involved detection of three virulence genes (bvfA, virB, ure) by PCR in 52 isolates of Brucella melitensis biovar 3, recovered from different animal species (28 sheep, 10 goats, 9 cattle and 5 buffaloes).Of the 52 B. melitensis strains; 48 (%) isolates carried bvfA genes, 51 (%) isolates had virB genes and 50 (%) isolates were positive for ure :// Table of Contents This guide contains general technical information for bacterial growth, propagation, preservation, and application.

Brucella phages have been isolated and studied for about years only, and Russian, Polish and South African workers have supplied most of the standard strains. The present author has been very active in these investigations and describes methods for isolation of Brucella phages from a large collection of Brucella.
The morphology of Brucella phages has been described and authors differ as Additional Physical Format: Online version: Parnas, Józef. Brucella phages, properties and application.

Lysis by Brucella phages is a useful tool to confirm the identity of Brucella species. Brucella biovars are differentiated by their requirement for CO 2 for growth, production of urease which varies from fast to very slow, H 2 S production, sensitivity to the dyes, basic fuchsine PARNAS et al.
1,2 obtained 14 samples of Brucella bacteriophage from old cultures of Brucella abortus and compared with these a Brucella phage originally isolated from manure in the :// The author emphasizes his belief that phages may be used more extensively for the taxonomic problems of Brucella and related bacteria.
By means of tatoles and figures he shows the phage specificity for Brucella, Francisella tularensis (sometimes classified with Brucella), Pasteurella pestis, P.
multocida and P. pseudotuberculosis. By the use of phages Tb, /XXIX, at the two doses of 1 RTD For decades, bacteriophages (phages) have been used for Brucella species identification in the diagnosis and epidemiology of brucellosis.
Traditional Brucella phage typing is a multi-day procedure including the isolation of a pure culture, a step that can take up to three weeks. In this study, we focused on the use of brucellaphages for sensitive detection of the pathogen in clinical and other Phages can exploit their bacterial hosts by lytic infection, when many viral particles are released at cell lysis, or by lysogeny, when phages integrate into the host’s :// Brucella belongs to the a2 proteobacteria, its closest relatives being predominantly plant pathogens such as Agrobacterium and Ochrobacter species, and in a more distant relationship, Bartonella la is a small Gram-negative coccobacillus that grows slowly and, in traditional culturing methods, may require specific growth media.
The recent sequencing of the complete genome of Phages were spotted onto the surface of the plates at a titre of the order 10 9 phages/ml with either a cross test comb or a pipette both holding 10 μl of individual phage lysates.
The plates were left to dry and were inspected for lysis zones after an overnight incubation at 30°C. The spot assay was used to assess the bactericide ability of Rev. sci. tech. Off. int. Epiz.,1 (1), Classification of the genus Brucella: the current position(*) by M.J.

Phages that can lyse members of the genus Brucella do not lyse members of other genera and thus can be useful in generic identification.
There are several phages active or partially active upon various members of this genus. The most dependable and useful is the Tbilisi :// This is a continuation of the work of PARNAS and ZALICHTA [above] who reported on the inhibition of the activity of Brucella phages by acetone preparations of the three types of Brucella, especially by a substrate of Br.
