Brucellosis is a widespread zoonosis. Currently the diagnosis of this zoonosis is based on microbiological and serological laboratory tests. Polymerase chain reaction (PCR) has been used to detect DNA from Brucella. Different target genes, primer pairs, PCR techniques, and extraction procedures have previously been published for Brucella detection. But only a few of these primers have been used in human samples, and only one study has been carried out to compare sensitivity between them. In the… 
Polymerase chain reaction–based assays for the diagnosis of human brucellosis
TLDR
The aim of this review was to summarize the main PCR techniques and their applications for diagnosis and follow-up of patients with brucellosis.
Polymerase Chain Reaction (PCR) Assay for Rapid Diagnosis and Its Role in Prevention of Human Brucellosis in Punjab, India
TLDR
Primer pair B4/B5 that amplifies a gene encoding a 31 kDa immunogenic outer membrane protein of Brucella species was used for PCR amplification and showed that early-case reporting is possible by rapid tests like PCR.
Evaluation of different primers for detection of Brucella in human and animal serum samples by using PCR method.
TLDR
F4/R2 and B4/B5 have the greatest sensitivity for purified bacteria and serum in the detection of Brucella respectively when DNA isolation is boiling, according to this study.
Multiplex PCR Assay for the Simultaneous Detection of the Brucella Genus in Human Whole Blood and Serum
TLDR
The purpose of this investigation was to extend and optimize a multiplex PCR for the identification of genus Brucella from serum and whole blood samples.
Development of a Differential PCR Assay for Detection of Brucella abortus and Brucella melitensis: an Analytical Approach for Monitoring of Brucella spp. in Foods of Animal Origin
TLDR
A PCR-based assay was the first step towards developing a novel kit with final aim of standardizing molecular identification of B. abortus and B. melitensis in foods of animal origin in Kazakhstan and other central Asia countries.
A PCR method with internal control for detection of Brucella spp. from bovine abortion samples
TLDR
The developed PCR method with an internal positive control has a potential for use in direct detection and identification of the Brucella spp.
Comparison of different PCR methods for detection of Brucella spp. in human blood samples.
TLDR
The results suggest that serum and blood analysis by conventional and real time PCR is a convenient and safe method for rapid and accurate diagnosis of brucellosis.
Real-time PCR carried out on DNA extracted from serum or blood sample is not a good method for surveillance of bovine brucellosis
TLDR
The results of this study suggest that RT-PCR targeting bcsp31 gene carried out on DNA extracted from serum or blood may not be a suitable method for surveillance of brucellosis in bovines.
Diagnosis of human brucellosis by PCR using l7/l12 and 16srRNA genes compared with common serological tests
TLDR
This study aims to compare the diagnosis of human brucellosis by PCR method using l7/l12 and 16srRNA genes and serological tests and concludes that PCR method has a higher sensitivity and specificity in diagnosis in comparison with serological Tests.

Comparison of three different PCR methods for detection of Brucella spp in human blood samples.
TLDR
Although the sensitivity of PCR using primers F4/R2 is affected by human DNA, they are still the most sensitive and they could provide a useful tool for the diagnosis of human brucellosis.
Specific detection of Brucella DNA by PCR
TLDR
The specificity and high sensitivity of the PCR assay may provide a valuable tool for the diagnosis of brucellosis and suggest a closer relationship between Brucella spp.
Rapid laboratory confirmation of human brucellosis by PCR analysis of a target sequence on the 31-kilodalton Brucella antigen DNA
TLDR
The test proved to be rapid and specific for the laboratory confirmation of acute human brucellosis and must be conducted to assess the utility of this test on additional patients with chronic relapsing bru cellosis as well as patients under treatment.
Specificity of a Polymerase Chain Reaction Assay of a Target Sequence on the 31-Kilodalton Brucella Antigen DNA Used to Diagnose Human Brucellosis
TLDR
A very good degree of specificity is confirmed in a polymerase chain reaction assay for detecting Brucella DNA using primers specific for the amplification of a 223 bp region of the sequence encoding a 31 kDa immunogenic BrucellA abortus protein (BCSP31).
Rapid diagnosis of human brucellosis by peripheral-blood PCR assay
TLDR
The results suggest that the PCR assay is rapid and easy to perform and highly sensitive and specific, and it may therefore be considered a useful tool for diagnosis of human brucellosis.
PCR Assay for Diagnosis of Human Brucellosis
TLDR
The study deals with the optimization of a method described in a previous work by these authors, in which they report a sensitivity of 100% and a specificity of 98% for rapid diagnosis of human brucellosis by PCR.
Serum Is the Preferred Clinical Specimen for Diagnosis of Human Brucellosis by PCR
TLDR
Serum is the optimal specimen for the diagnosis of brucellosis by PCR, a choice that leads to assay simplification and shortens turnaround time.

TLDR
Results showed that PCR assay can be applied with serology for the diagnosis of brucellosis suspected cases and relapses regardless of the duration or type of the disease without relying on the blood cultures, especially in chronic cases.
Single-step PCR for detection of Brucella spp. from blood and milk of infected animals
TLDR
The sensitivity of the test and its ability to detect the pathogen in samples from the field reveal a promising advance in the diagnosis of brucellosis in animals and humans.
