This study describes the isolation and identification of the bacteria from cage-cultured <jats:italic>Etroplus suratensis<\/jats:italic> that experienced moderate to severe mortalities in Kerala, India. Gram-positive, catalase-negative <jats:italic>S. agalactiae<\/jats:italic> was identified from brain, eye and liver of the fish by antigen grouping and 16S rDNA sequencing. Multiplex PCR confirmed that the isolate belonged to capsular serotype Ia. Antibiotic susceptibility tests showed that the isolate was resistant to methicillin, vancomycin, tetracycline, kanamycin, streptomycin, ampicillin, oxacillin and amikacin. Histological sections of the infected <jats:italic>E. suratensis<\/jats:italic> brain revealed infiltration of inflammatory cells, vacuolation and meningitis. This report is the first description of <jats:italic>S. agalactiae<\/jats:italic> as a primary pathogen causing mortalities in <jats:italic>E. suratensis<\/jats:italic> culture in Kerala.<\/jats:p>","DOI":"10.3354\/dao03726","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T09:48:56Z","timestamp":1680083336000},"page":"1-6","update-policy":"https:\/\/doi.org\/10.3354\/policy","source":"Crossref","is-referenced-by-count":2,"title":["Isolation and identification of Streptococcus agalactiae in cage-cultured green chromide Etroplus suratensis in Kerala, India"],"prefix":"10.3354","volume":"154","author":[{"given":"SK","family":"Girijan","sequence":"first","affiliation":[{"name":"Department of Aquatic Animal Health Management, Kerala University of Fisheries and Ocean Studies, Kochi, Kerala 682506, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Krishnan","sequence":"additional","affiliation":[{"name":"Department of Aqualife Medicine, Chonnam National University, Yeosu, Jeonnam 61186, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K","family":"Maniyappan","sequence":"additional","affiliation":[{"name":"Department of Aquatic Animal Health Management, Kerala University of Fisheries and Ocean Studies, Kochi, Kerala 682506, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Pillai","sequence":"additional","affiliation":[{"name":"Department of Aquatic Animal Health Management, Kerala University of Fisheries and Ocean Studies, Kochi, Kerala 682506, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1913","reference":[{"doi-asserted-by":"publisher","key":"Ref1","DOI":"10.1186\/2193-1801-2-286"},{"doi-asserted-by":"publisher","key":"Ref2","DOI":"10.3923\/javaa.2010.2640.2646"},{"doi-asserted-by":"publisher","key":"Ref3","DOI":"10.1515\/aopf-2017-0018"},{"doi-asserted-by":"crossref","unstructured":"Amal MN, Zamri-Saad M, Iftikhar AR, Siti-Zahrah A, Aziel S, Fahmi S (2012) An outbreak of Streptococcus agalactiae infection in cage-cultured golden pompano, Trachinotus blochii (Lacepede), in Malaysia.
