This manuscript reports on a co-infection of chickens with Staphylococcus lentus and Staphylococcus aureus associated with an outbreak of arthritis, synovitis, and osteomyelitis in an organic broiler breeder flock in Austria. Clinically, the affected flock showed weakness, lethargy, lameness, and increased mortality. Post-mortem examinations identified purulent arthritis and femoral head necrosis. Bacteriological analysis using MALDI-TOF MS identified both S. aureus and S. lentus in the affected joints. Antibiotic resistance testing revealed significant resistance, particularly in S. lentus. Histological analysis showed severe inflammation and bacterial colonies in the joints. While S. aureus is a common pathogen in poultry, S. lentus is less frequently reported. This study emphasises the need for detailed bacterial characterisation in outbreaks to better understand the role of less common pathogens like S. lentus. Further research is necessary to elucidate the impact of S. lentus on poultry health and its role in causing arthritis and synovitis, highlighting the importance of comprehensive investigation in such outbreaks.<\/jats:p>","DOI":"10.3390\/ani14172574","type":"journal-article","created":{"date-parts":[[2024,9,4]],"date-time":"2024-09-04T05:54:47Z","timestamp":1725429287000},"page":"2574","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Co-Infection of Chickens with Staphylococcus lentus and Staphylococcus aureus from an Outbreak of Arthritis, Synovitis, and Osteomyelitis Argues for Detailed Characterisation of Isolates"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5887-8260","authenticated-orcid":false,"given":"Miguel","family":"Matos","sequence":"first","affiliation":[{"name":"Clinic Unit for Poultry Medicine, Clinical Center for Population Medicine in Fish, Pigs, and Poultry, University of Veterinary Medicine, Veterinaerplatz 1, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Mitsch","sequence":"additional","affiliation":[{"name":"Tierarzt GmbH Dr. Mitsch, Hauffgasse 24, 1110 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2412-1248","authenticated-orcid":false,"given":"Dieter","family":"Liebhart","sequence":"additional","affiliation":[{"name":"Clinic Unit for Poultry Medicine, Clinical Center for Population Medicine in Fish, Pigs, and Poultry, University of Veterinary Medicine, Veterinaerplatz 1, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6991-0120","authenticated-orcid":false,"given":"Michael","family":"Hess","sequence":"additional","affiliation":[{"name":"Clinic Unit for Poultry Medicine, Clinical Center for Population Medicine in Fish, Pigs, and Poultry, University of Veterinary Medicine, Veterinaerplatz 1, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3535-5157","authenticated-orcid":false,"given":"Claudia","family":"Hess","sequence":"additional","affiliation":[{"name":"Clinic Unit for Poultry Medicine, Clinical Center for Population Medicine in Fish, Pigs, and Poultry, University of Veterinary Medicine, Veterinaerplatz 1, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5607","DOI":"10.1099\/ijsem.0.004332","article-title":"List of Prokaryotic Names with Standing in Nomenclature (LPSN) Moves to the DSMZ","volume":"70","author":"Parte","year":"2020","journal-title":"Int.
