The molecular basis of the FPSRs is reviewed through analyzing the components of the cell wall of Gram-negative bacteria, especially the surface lipopolysaccharide (LPS) with details related to brucellae. After evaluating the efforts that have been made to solve target specificity problems of serologic tests, the following conclusions can be drawn: (i) resolving the FPSR problem requires a deeper understanding than we currently possess, both of Brucella immunology and of the current serology tests; (ii) the practical solutions will be as expensive as the related research; and (iii) the root cause of FPSRs is the application of the same type of antigen (S-type LPS) in the currently approved tests. Thus, new approaches are necessary to resolve the problems stemming from FPSR. Such approaches suggested by this paper are: (i) the application of antigens from R-type bacteria; or (ii) the further development of specific brucellin-based skin tests; or (iii) the application of microbial cell-free DNA as analyte, whose approach is detailed in this paper.<\/jats:p>","DOI":"10.3390\/tropicalmed8050274","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T10:49:51Z","timestamp":1683888591000},"page":"274","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["False Positives in Brucellosis Serology: Wrong Bait and Wrong Pond?"],"prefix":"10.3390","volume":"8","author":[{"given":"Borb\u00e1la","family":"B\u00e1ny\u00e1sz","sequence":"first","affiliation":[{"name":"Department of Microbiology and Infectious Diseases, University of Veterinary Medicine Budapest, 1143 Budapest, Hungary"},{"name":"Laboratory of Immunology, Veterinary Diagnostic Directorate, National Food Chain Safety Office, 1143 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f3zsef","family":"Antal","sequence":"additional","affiliation":[{"name":"Omixon Biocomputing Ltd., 1117 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00e9la","family":"D\u00e9nes","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Infectious Diseases, University of Veterinary Medicine Budapest, 1143 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"380","DOI":"10.7861\/clinmedicine.18-5-380","article-title":"The British Army\u2019s contribution to tropical medicine","volume":"18","author":"Herron","year":"2018","journal-title":"Clin.
