{"doi":"10.1128/msphere.00113-23","title":"Serum Immune Responses to Group A Streptococcal Antigens following Pharyngeal Acquisitions among Children in Cape Town, South Africa","abstract":"(GAS) antigens will serve to refine diagnostic approaches and contribute to vaccine efforts, which together will serve to reduce the burden of rheumatic heart disease, a major source of morbidity and mortality especially in the developing world. This study, utilizing an antibody-specific assay, uncovered three patterns of response profiles following GAS infection, among 256 children presenting with sore throat to local clinics. Overall, the response profiles were complex and variable. Of note, a preceding infection was most convincingly represented by a GAS-positive culture with an immune response to at least one shared antigen and M peptide. Also, more than a third of participants demonstrated no immune response despite a positive culture. All antigens tested were immunogenic, providing guidance for future vaccine development.","journal":"mSphere","year":2023,"id":359347,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":10,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.963,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":406545,"name":"Babu Muhamed","orcid":"0000-0003-4832-0671","position":1,"is_corresponding":false},{"id":407983,"name":"Kélin Engel","orcid":null,"position":2,"is_corresponding":false},{"id":794999,"name":"Kimona Rampersadh","orcid":"0000-0001-5834-4672","position":3,"is_corresponding":false},{"id":1110313,"name":"Rezeen Daniels","orcid":null,"position":4,"is_corresponding":false},{"id":1110314,"name":"Lwazi Mhlanti","orcid":null,"position":5,"is_corresponding":false},{"id":427164,"name":"Thomas A.
