Visceral leishmaniasis is the second most lethal parasitic disease after malaria and there is so far no human vaccine. Leishmania donovani is a causative agent of visceral leishmaniasis in South East Asia and Eastern Africa. However, in Sri Lanka, L. donovani causes mainly cutaneous leishmaniasis, while visceral leishmaniasis is rare. We investigate here the possibility that the cutaneous form of L. donovani can provide immunological protection against the visceral form of the disease, as a potential explanation for why visceral leishmaniasis is rare in Sri Lanka. Subcutaneous immunization with a cutaneous clinical isolate from Sri Lanka was significantly protective against visceral leishmaniasis in BALB/c mice. Protection was associated with a mixed Th1/Th2 response. These results provide a possible rationale for the scarcity of visceral leishmaniasis in Sri Lanka and could guide leishmaniasis vaccine development efforts.","is_dataset_classified":null,"base_score":3.8918202981106265,"endowment":3.8918202981106265,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23219435","pmcid":null,"openalex_id":"https://openalex.org/W2047763566","authors":[],"funders":[],"total_grants":0,"fwci":3.6857,"citation_percentile":0.92461681,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2014,"count":5},{"year":2015,"count":6},{"year":2016,"count":9},{"year":2017,"count":6},{"year":2018,"count":2},{"year":2019,"count":3},{"year":2020,"count":6},{"year":2021,"count":3},{"year":2022,"count":2},{"year":2023,"count":2},{"year":2025,"count":2},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0264410X1201715X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0264410X1201715X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.vaccine.2012.11.065","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23219435","host_type":"repository"}],"fields_of_study":["Research on Leishmaniasis Studies","Trypanosoma species research and implications","Adult","Animals","Disease Models, Animal","Female","Humans","Leishmania donovani","Leishmaniasis Vaccines","Leishmaniasis, Visceral","Male","Mice","Mice, Inbred BALB C","Middle Aged","Th1 Cells","Th2 Cells","Vaccines, Attenuated"],"mesh_terms":["Adult","Animals","Disease Models, Animal","Female","Humans","Leishmania donovani","Leishmaniasis, Visceral","Male","Mice, Inbred BALB C","Middle Aged","Vaccines, Attenuated","Th1 Cells","Th2 Cells","Mice","Leishmaniasis Vaccines"],"keywords":["Visceral leishmaniasis","Leishmaniasis","Leishmania donovani","Cutaneous leishmaniasis","Leishmania","Immunology","Medicine","Parasitic disease","Immunization","Tropical disease","Disease","Virology","Pathology","Immune system","Parasite hosting"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T03:02:00.816320Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
