Since the Cry toxins of <em>B. thuringiensis</em> are public goods that benefit groups of bacteria, not individual cells, we employed a passage design which provided reproductive benefits to groups of pathogens, based on infectivity. Passage of one bacterial genotype (<em>Bt morrisoni)</em> led to the loss of virulence, while the second genotype (<em>Bt galleriae</em>) evolved virulence that was dependent on selection treatment. In contrast to expectation, selection in <em>P. xylostella</em> produced lineages with increases in virulence in both hosts; selection in <em>S. frugiperda</em> led to very low virulence and the alternating host treatment produced intermediate levels of virulence. Modest increases in virulence were accompanied by a reduction in fitness, consistent with a cost of increased investment in virulence factors. In contrast, infection in <em>S. frugiperda</em> selected for cheaters that had reduced investment in Cry toxins and high competitive fitness within hosts. In conclusion, the selection favouring cheaters depended strongly on both host species and bacterial genotype.

The <em>in vivo</em> assay with <em>Artemia franciscana</em> demonstrated that ThurH is non-toxic at 1000 µg/ml. Challenge tests with <em>A. franciscana</em> at 100 mL (4 artemias/mL) and histological analysis demonstrated the efficacy of ThurH in <em>in vivo</em> trials, improving organism survival with two doses (MIC). These results demonstrate for the first time in an <em>in vivo</em> assay that ThurH has potential as an antimicrobial against <em>S. iniae</em> in aquaculture.</div></div>","PeriodicalId":16296,"journal":{"name":"Journal of invertebrate pathology","volume":"216 ","pages":"Article 108550"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146105721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
