Editing Salmonella (section)

== Serotyping ==
Serotyping is done by mixing cells with antibodies for a particular antigen. It can give some idea about risk. A 2014 study showed that ''S.'' Reading is very common among young [[turkey (bird)|turkey]] samples, but it is not a significant contributor to human salmonellosis.<ref name=":0">{{cite web|url=https://www.fsis.usda.gov/sites/default/files/media_file/2020-10/Salmonella-Serotype-Annual-2014.pdf|title=Serotypes Profile of Salmonella Isolates from Meat and Poultry Products, January 1998 through December 2014}}</ref> Serotyping can assist in identifying the source of contamination by matching serotypes in people with serotypes in the suspected source of infection.<ref name=":1">{{cite web|url=https://www.cdc.gov/foodsafety/outbreaks/investigating-outbreaks/investigations/index.html|title=Steps in a Foodborne Outbreak Investigation|date=2018-11-09}}</ref>  Appropriate prophylactic treatment can be identified from the known antibiotic resistance of the serotype.<ref name=":2">{{cite journal | vauthors = Yoon KB, Song BJ, Shin MY, Lim HC, Yoon YH, Jeon DY, Ha H, Yang SI, Kim JB | title = Antibiotic Resistance Patterns and Serotypes of ''Salmonella'' spp. Isolated at Jeollanam-do in Korea | journal = Osong Public Health and Research Perspectives | volume = 8 | issue = 3 | pages = 211–219 | date = June 2017 | pmid = 28781944 | pmc = 5525558 | doi = 10.24171/j.phrp.2017.8.3.08 }}</ref>

Newer methods of "serotyping" include xMAP and [[real-time PCR]], two methods based on DNA sequences instead of antibody reactions. These methods can be potentially faster, thanks to advances in sequencing technology. These "molecular serotyping" systems actually perform [[Genotyping by sequencing|genotyping]] of the genes that determine surface antigens.<ref>{{cite journal | vauthors = Luo Y, Huang C, Ye J, Octavia S, Wang H, Dunbar SA, Jin D, Tang YW, Lan R | title = Comparison of xMAP ''Salmonella'' Serotyping Assay With Traditional Serotyping and Discordance Resolution by Whole Genome Sequencing | journal = Frontiers in Cellular and Infection Microbiology | volume = 10 | page = 452 | date = 2020-09-07 | pmid = 33014887 | pmc = 7504902 | doi = 10.3389/fcimb.2020.00452 | doi-access = free }}</ref><ref>{{cite journal | vauthors = Nair S, Patel V, Hickey T, Maguire C, Greig DR, Lee W, Godbole G, Grant K, Chattaway MA | title = Real-Time PCR Assay for Differentiation of Typhoidal and Nontyphoidal ''Salmonella'' | journal = Journal of Clinical Microbiology | volume = 57 | issue = 8 | pages = e00167–19 | date = August 2019 | pmid = 31167843 | pmc = 6663909 | doi = 10.1128/JCM.00167-19 | veditors = Ledeboer NA }}</ref>
