Consumption of contaminated poultry meat is regarded as the main source of human infection. This study was undertaken to determine the antimicrobial susceptibility and the molecular epidemiology of 205 Campylobacter isolates derived from Greek flocks slaughtered in three different slaughterhouses over a 14-month period. A total of 98.5% of the isolates were resistant to at least one antimicrobial agent. In terms of multidrug resistance, 11.7% of isolates were resistant to three or more groups of antimicrobials. Extremely high resistance to fluoroquinolones (89%), very high resistance to tetracycline (69%), and low resistance to macrolides (7%) were detected. FlaA sequencing was performed for the subtyping of 64 C. jejuni and 58 C. coli isolates. No prevalence of a specific flaA type was observed, indicating the genetic diversity of the isolates, while some flaA types were found to share similar antimicrobial resistance patterns. Phylogenetic trees were constructed using the neighbor-joining method. Seven clusters of the C. jejuni phylogenetic tree and three clusters of the C. coli tree were considered significant with bootstrap values &gt;75%. Some isolates clustered together were originated from the same or adjacent farms, indicating transmission via personnel or shared equipment. These results are important and help further the understanding of the molecular epidemiology and antimicrobial resistance of Campylobacter spp. derived from poultry in Greece.<\/jats:p>","DOI":"10.3390\/vetsci8050068","type":"journal-article","created":{"date-parts":[[2021,4,21]],"date-time":"2021-04-21T21:25:10Z","timestamp":1619040310000},"page":"68","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Antimicrobial Resistance, FlaA Sequencing, and Phylogenetic Analysis of Campylobacter Isolates from Broiler Chicken Flocks in Greece"],"prefix":"10.3390","volume":"8","author":[{"given":"George","family":"Natsos","sequence":"first","affiliation":[{"name":"Department of Poultry Diseases, Veterinary Faculty, University of Thessaly, 43100 Karditsa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niki K.","family":"Mouttotou","sequence":"additional","affiliation":[{"name":"Ministry of Rural Development and Foods, National Reference Laboratory for <i>Salmonella<\/i> and Antimicrobial Resistance, 34100 Chalkida, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8883-7275","authenticated-orcid":false,"given":"Emmanouil","family":"Magiorkinis","sequence":"additional","affiliation":[{"name":"Department of Laboratory Haematology, General Hospital for Chest Diseases \u201cSotiria\u201d, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1880-7366","authenticated-orcid":false,"given":"Anastasios","family":"Ioannidis","sequence":"additional","affiliation":[{"name":"Department of Nursing, Faculty of Human Movement and Quality of Life Sciences, University of Peloponnese, 23100 Sparta, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Magana","sequence":"additional","affiliation":[{"name":"Department of Nursing, Faculty of Human Movement and Quality of Life Sciences, University of Peloponnese, 23100 Sparta, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1251-8355","authenticated-orcid":false,"given":"Stylianos","family":"Chatzipanagiotou","sequence":"additional","affiliation":[{"name":"Department of Medical Biopathology, Medical School\u2013Eginition Hospital, National and Kapodistrian University of Athens, 15772 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0240-4194","authenticated-orcid":false,"given":"Konstantinos C.","family":"Koutoulis","sequence":"additional","affiliation":[{"name":"Department of Poultry Diseases, Veterinary Faculty, University of Thessaly, 43100 Karditsa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.12681\/jhvms.15624","article-title":"Campylobacter spp. infection in humans and poultry","volume":"67","author":"Natsos","year":"2016","journal-title":"J.
