Fresh faecal samples (n=110) of captive ungulate species were collected from Lahore Zoo (n=55), Jallo Park (n=35) and the woodland wildlife park (n=20).

Methods such as the fl otation concentration technique, the sedimentation technique and the faecal egg count per gram were used to analyze the diversity of endoparasites in faecal samples. Parasitological analyses detect 10 parasites in the faecal sample. Kruskal-Wallis Post Hoc statistical test was used to compare the prevalence of the specifi ed parasitic species among different captive ungulates. The results show that individuals of lower age are more susceptible to infections. The overall diversity of GI parasitic infections in captive ungulates was 77.25 %. Survivability of captive ungulates could be affected by the prevalence of parasitic species.

The species involved are Lecithocladium excisum, Parahemiurus merus, Tormopsolus orientalis, Stephanostomum euzeti and Bucephalus gorgon. Tormopsolus orientalis and B. gorgon were recorded for the fi rst time off the Algerian waters. S. euzeti was described for the second time, based on adult worms, since its original description. As for L. excisum, S. dumerili represents a new host record. The data analysis indicated that B. gorgon had the highest values of prevalence (85.95 %), mean abundance (64) and mean intensity (74.46), qualifying it as a core species. Spearman's correlation test revealed a strong positive correlation between the mean abundance and the mean intensity of S. euzeti, as well as the size of the host.

Therefore, gaining a thorough comprehension of the diversity of intestinal parasites and the factors infl uencing their interaction is of primary importance. This study assesses the diversity of gastrointestinal parasites in wild rodents in Lebanon. Two thousand fi ve hundred trapping nights were carried out in fi ve Himas in Lebanon during the spring and fall of 2022. A total of 205 rodents, including Apodemus mystacinus, Apodemus flavicollis, Apodemus hermonensis, Microtus guentheri, Rattus rattus, and Mus musculus, were trapped and examined for intestinal parasites. Nine intestinal parasites were isolated, including one cestode species, Hymenolepis diminuta (11.7 %), and eight nematodes: Ascaris lumbricoides (31.7 %), Trichuris muris (7.8 %), Aspiculuris tetraptera (7.3 %), Heligmosomoides polygyrus (6.8 %), Syphacia muris (3.9 %), Syphacia obvelata (3.4 %), Capillaria spp. (2.4 %), and Physaloptera spp (0.5 %). The species and gender did not infl uence the number of rodents infected with these parasites. However, the season impacted the number of rodents infected with A. lumbricoides, T. muris, and S. muris. Infection of rodents with H. diminuta and A. lumbricoides was infl uenced by the site of trapping. Among the collected parasites, A. lumbricoides, H. diminuta, and Syphacia obvelata are considered zoonotic. This study showed that preserving parasite-host dynamics and biological cycles depends heavily on environmental stability. This project will further advance the understanding of rodent parasites and support future studies on endoparasites in Lebanon and the region.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"62 2","pages":"120-134"},"PeriodicalIF":1.2,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12498213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145245799","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}

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 (Fasciola hepatica 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 F. hepatica 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 Cooperia spp., Oesophagostomum spp., and Haemonchus 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. In conclusion, age, sex, and farm management practices influence the prevalence of nematodes and trematodes. Nematode prevalence exceeded 30 % for most of the year, while trematode prevalence ranged from 12 % to 20 %.","PeriodicalId":55061,"journal":{"name":"Helminthologia","volume":"62 1","pages":"30-39"},"PeriodicalIF":1.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12117615/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183427","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}
