Gastrointestinal nematodes (GIN) are highly prevalent, prompting us to investigate factors affecting the prevalence of endoparasites in pre-weaning calves in a warm, humid climate in Mexico. Fecal samples were analyzed to assess fecal egg count (FEC) dynamics and endoparasite prevalence. The prevalence of trematodes (<i>Fasciola hepatica</i> and paramphistomids) was determined on 12 beef cattle farms in the rainy season from May to September 2022 and July to November 2023. Nematode prevalence was monitored on four farms during 2022 and 2023. In addition, on one farm, the FEC was compared between dewormed and untreated groups. Coprocultures were conducted to obtain third-stage larvae for species identification based on morphology. The prevalence of <i>F. hepatica</i> was 12 % (77/640), while paramphistomids had a prevalence of 20.5 % (131/640). Trichostrongylids showed a prevalence exceeding 30 %, with maximum values reaching 93 %. The predominant species identified from coprocultures were <i>Cooperia</i> spp., <i>Oesophagostomum</i> spp., and <i>Haemonchu</i>s spp. Dewormed calves exhibited similar nematode eggs per gram of feces (EPG) to the untreated group, and nematode EPG in calves tended to decrease with age.

The injured sea turtles are regularly transferred for treatment to the Sea Turtle Research, Rescue and Rehabilitation Center (DEKAMER) Muğla Ortaca-Dalyan (Turkey) from the different coasts of the these two seasthese include Çanakkale, Balıkesir, İzmir and Aydın (Aegean Sea); Antalya and Mersin (Mediterranean Sea) and also Muğla (it has two coasts both Aegean Sea and Mediterranean Sea). In this study, both internal and external parasites and epibiont species of turtles that died during treatment were examined. This is the first detailed parasitological and epibiont study on these sea turtles in the Turkish coast. Twenty-two adult <i>Caretta caretta</i> and twelve green turtles were examined and these symbiotic groups were recorded: endoparasitic digeneans and nematodes, and epibiotic annelids and cirripeds (barnacles). The observed three digenean species (<i>Pyelosomum renicapite</i>, <i>Learedius learedi</i> and <i>Deuterobaris proteus</i>) are recorded in Turkey for the first time. Also, <i>Ch. mydas</i> and <i>C. caretta</i> represent new host records for these digenean species in Turkey. <i>Ch. mydas</i> represents a new host record for two cirriped species (<i>Chelonibia testudinaria</i> and <i>Lepas hillii</i>) from Turkey and <i>C. caretta</i> also represent a new host record for <i>Ozobranchus margoi</i> from Turkey. Based on the available literature, the implications of these symbionts on sea turtle health are discussed, highlighting the importance of recording parasitic data of sea turtles. The study of internal and external parasites is very important, especially for the treatment of sea turtles under rehabilitation.</p>","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"62 1","pages":"40-49"},"PeriodicalIF":1.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12117616/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
