VL is a zoonotic disease, with dogs as the predominant domestic reservoir. Traditionally, this disease is transmitted via sand flies of the genus Phlebotomus or Lutzomyia as vectors. Case reports of transmission in non-endemic areas have increased, where transmission is predominantly vertical, sexual, or bloodborne. L. infantum has been shown to be enzootic in hunting hounds within the United States (U.S.), with no indication of vector borne transmission. In this population, there is very high risk of parasite spread if the dam's diagnostic status is positive. In comparison, very little is known about the risk if the sire not the dam is positive for L. infantum. This is a retrospective cohort study of 24 U.S. hunting hound sires' L. infantum exposure between 2013 and 2022 and the resultant evidence of infection in their 183 pups over that time.

Here, we integrated bioinformatic analyses, functional assays in vitro and mouse models in vivo to systematically determine the effects of antibodies directed against the JEV fusion loop (FL) region on ZIKV infection. Sequence alignment and structural analysis revealed complete amino acid identity and almost identical three-dimensional conformations between the FL regions of the two viruses, providing a molecular basis for cross-reactivity. Antisera generated against the JEV FL region recognized ZIKV particles and displayed concentration-dependent bidirectional effects. Increased and decreased antibody levels respectively neutralized viral entry and replication, and facilitated infection via antibody-dependent enhancement (ADE). These effects were confirmed in vivo, in which high and low antibody doses reduced tissue pathology and improved survival, and increased viremia and exacerbated inflammatory responses, respectively. These findings highlight the importance of antibody concentration in determining whether cross-reactive responses to conserved structural elements engender neutralization or enhancement response. Our findings provide experimental evidence for assessing ZIKV susceptibility in JEV-vaccinated populations and offer structural insights for designing flavivirus vaccines that maximize protection while minimizing ADE risk.

In multivariate analysis, factors independently associated with receiving a syndromic diagnosis were age ≥ 30 years (OR = 1.16; 95% CI: 1.05-1.20), male sex (OR = 2.31; 95% CI: 1.75-2.45), single marital status (OR = 1.82; 95% CI: 1.43-2.21), irregular condom use (OR = 3.21; 95% CI: 2.46-3.60), and having two or more casual partners (OR = 3.42; 95% CI: 2.94-3.90).</p><p><strong>Conclusions/significance: </strong>Despite inherent limitations, the syndromic approach remains an essential strategy for STI control in resource-constrained contexts such as the Amazon. It facilitates prompt treatment and broadens access to care where laboratory confirmation is unavailable. Integrating syndromic and etiological approaches is vital to improve diagnostic accuracy, optimize antimicrobial use, and strengthen public health responses to STIs in the region.</p>","PeriodicalId":49000,"journal":{"name":"PLoS Neglected Tropical Diseases","volume":"20 5","pages":"e0014282"},"PeriodicalIF":3.4,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13155674/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
