{"title":"EXPLORING DIFFERENTIAL GENE EXPRESSION PROFILES OF DERO (ALLODERO) HYLAE IN THEIR PARASITIC AND FREE-LIVING FORMS.","authors":"Claire Bonham, Ashley Roguski, Gabriel J Langford, Jason Macrander","doi":"10.1645/23-18","DOIUrl":"https://doi.org/10.1645/23-18","url":null,"abstract":"<p><p>Parasitism is ubiquitous, yet little is known about the evolutionary mechanisms that lead to a parasitic lifestyle. Facultative parasites can switch between free-living and parasitic lifestyles, which may provide an opportunity for researchers to study the genetic mechanisms underlying a transition to parasitism. The oligochaete Dero (Allodero) hylae is a facultative parasite commonly found within the ureter of various anuran species, such as the Cuban tree frog (Osteopilus septentrionalis). The Dero hylae worm passes into the frog's cloaca, where it then infects the ureter. In the ureter, the worm loses its free-living characteristics such as hair setae, dorsal setae, a digestive tract, and fossa with gills as it transitions to a parasitic lifestyle. The parasite may be expelled from its host during urination, and when this occurs the worm will reacquire its free-living characteristics. The focus of this study was to compare the differential gene expression profiles observed when this rapid morphological change takes place. Specimens of D. hylae were extracted from wild Cuban tree frogs and either flash-frozen to capture the parasitic RNA gene expression profile or cultured for 2 wk and allowed to metamorphose to their free-living stage and then flash-frozen. The extracted RNA was used for de novo transcriptome assembly, and we conducted a differential gene expression analysis using an RNA Tag-Seq approach for both the free-living and parasitic life forms. Based on these results, we identified 213 differentially expressed transcripts between the 2 developmental forms, with 190 of these up-regulated in the free-living life form. Although over half of the differential genes recovered did not result in any significant BLAST hits, many of these genes did provide insight into which molecular signals are potentially used after the parasite transforms into the free-living form. This analysis provides significant insight into differentially expressed transcripts associated with the drastic morphological changes observed in this rare case of oligochaete parasitism by D. hylae encompassing both free-living and parasitic forms.</p>","PeriodicalId":16659,"journal":{"name":"Journal of Parasitology","volume":"110 6","pages":"690-696"},"PeriodicalIF":1.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(found in the anterior salivary glands) and its relationship with the gonad development stages (GDSs) of the host. From August 2009 to May 2010, 439 specimens of O. maya were caught in 2 localities on the northern coast of the Yucatán Peninsula: Dzilam de Bravo (n = 239) and Ria Lagartos (n = 200). The mantle length, eviscerated body weight, reproductive complex weight, and gonad weight were recorded in each specimen. Portions of each gonad were used to identify the GDS based on histology for each individual to determine the periodicity of the reproductive cycle and the monthly variation in the reproductive complex weight. Temporal variation in the monthly mean abundance of cestodes but not in prevalence was evident. A permutational multivariate analysis of variance indicated that variation in the mean abundance of Prochristianella sp. was affected by host GDS, month of sampling, host sex, and sampling locality; however, the first-order interactions indicated that the most were important variables were GDS, month, and host sex. General linear model analyses also indicated that the size, reproductive status, and sex of the hosts were significantly related to the abundance of cestodes. Temporal variation was evident in the monthly mean abundance of Prochristianella sp. but not in its prevalence; the number of parasites increased in octopuses from September to December. Regarding the GDS, the mean abundance of the parasite increased as gonads developed, and gonad development was related to water temperature and time, which are linked to season and the upwelling that occurs in spring and summer. In the oral cavity of octopuses, variations in cestode abundance related to host sex, size, and reproductive status can have major implications for the production of saliva, an essential secretion for food acquisition and defense in this host, and could affect octopus reproduction and recruitment of this food resource so important for the Yucatán Peninsula.</p>","PeriodicalId":16659,"journal":{"name":"Journal of Parasitology","volume":"110 6","pages":"670-678"},"PeriodicalIF":1.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two species, Echinococcus granulosus sensu lato and Echinococcus multilocularis, are endemic to North America and are the etiologic agents of cystic echinococcosis and alveolar echinococcosis, respectively. North America is currently experiencing an epidemiological shift in the state of transmission, distribution, and prevalence of E. multilocularis, following the introduction of the European variant of the parasite. The rapid expansion of the parasite into the northeastern United States has resulted in novel detections of spillover to humans, indicating the need for active surveillance to direct public health education and disease control measures. Our surveillance of the parasite in definitive hosts in New York State from 2019 to 2023 yielded 8 detections of the parasite, for a sample prevalence of 8.3% (8/96). Phylogenetic analysis of mitochondrial markers confirmed that all New York isolates belong to the European lineage and group in a well-supported clade with E. multilocularis isolates described from Slovakia and Poland. Investigation of the highly polymorphic EmsB microsatellite marker revealed several E. multilocularis genotypes circulating in New York, including 1 that is distinct from European isolates detected in western North America. These data are consistent with 1 or more unique introductions from Europe rather than a spread from western regions of Canada and the United States, where other European variants are found. Echinococcus multilocularis appears to have a complex epidemiology in North America that warrants further detailed surveillance to evaluate the risks for zoonotic transmission.</p>","PeriodicalId":16659,"journal":{"name":"Journal of Parasitology","volume":"110 6","pages":"697-708"},"PeriodicalIF":1.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
