Persister cells formation and expression of type II Toxin-Antitoxin system genes in Brucella melitensis (16M) and Brucella abortus (B19)
Background & Objective: Persister cells are defined as a subpopulation of bacteria that are capable of reducing their metabolism and switching to dormancy in stress conditions. Persister cells formation has been attributed to numerous mechanisms, including stringent response and Toxin-Antitoxin (TA) systems. This study aimed to investigate the hypothetical role of TA systems in...
متن کاملA serological comparison of complement fixation reactions using Brucella abortus and B. melitensis antigens in B. abortus infected cattle.
Brucella abortus and B. melitensis antigens were used in parallel on the National Standard Brucella abortus antiserum and on field sera coming from cattle where practically exclusively B. abortus biotypes 1 and 2 have been isolated over the last 11 years. With the National Standard serum the titres to B. melitensis were consistently lower than those to B. abortus antigen. Most were 1 dilution (...
متن کاملDetection of Brucella melitensis and Brucella abortus strains using a single-stage PCR method
Brucella melitensis and Brucella abortus are of the most important causes of brucellosis, an infectious disease which is transmitted either directly or indirectly including consuming unpasteurized dairy products. Both strains are considered endemic in Iran. Common diagnostic methods such as bacteriologic cultures are difficult and time consuming regarding the bacteria. The aim of this study w...
متن کاملReal-time multiplex PCR assay for detection of Brucella spp., B. abortus, and B. melitensis.
The identification of Brucella can be a time-consuming and labor-intensive process that places personnel at risk for laboratory-acquired infection. Here, we describe a real-time PCR assay for confirmation of presumptive Brucella isolates. The assay was designed in a multiplex format that will allow the rapid identification of Brucella spp., B. abortus, and B. melitensis in a single test.
متن کاملEpidemiology of brucellosis in domestic animals caused by Brucella melitensis, Brucella suis and Brucella abortus.
Brucellosis is a disease that causes severe economic losses for livestock farms worldwide. Brucella melitensis, B. abortus and B. suis, which are transmitted between animals both vertically and horizontally, cause abortion and infertility in their primary natural hosts - goats and sheep (B. melitensis), cows (B. abortus) and sows (B. suis). Brucella spp. infect not only their preferred hosts bu...
