In conclusion, this is the first report from Pakistan highlighting a high prevalence of <em>T. gondii</em> in <em>A. persicus</em> infesting domestic poultry suggesting a potential zoonotic risk to humans through the consumption of infected poultry.

It contains 15 genera, of which only <em>Allocreadium</em>, <em>Creptotrema</em>, <em>Wallinia</em> and <em>Creptotrematina</em> have been reported in Argentina. The records of <em>Allocreadium</em> species still require further verification. The discovery of an allocreadiid digenean parasitizing <em>Pseudocorynopoma doriae</em> led us to erect a new genus for which the name <em>Martorellia</em> n. gen is proposed. It is characterized by poorly developed ventrolateral muscular lobes and a transversely elongated ovary, with the most characteristic feature being the presence of vitelline follicles in two fields (one anterior at level of ventral sucker and one posterior to the testis), which are not confluent in the middle. The phylogenetic tree reconstructed with 28S rDNA sequences placed the new genus as the sister taxa of <em>Creptotrematina</em>. Although both genera are separated by a small genetic distance, it is comparable with those separating other allocreadiid genera. The discovery of <em>Martorellia liciae</em> gen et sp. nov. provides further evidence of the great diversity of Allocreadiidae in South America. The analysis of new samples from different South American hosts with an integrative taxonomic approach as the one used here allows a better understanding of the evolutionary history and biogeography of allocreadiids in the Americas.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"57 ","pages":"Article 101150"},"PeriodicalIF":1.4,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present report describes a heavy infestation of yellow-legged gulls (<em>Larus michahellis</em>) with <em>Saemundssonia</em> species in Iran. Three yellow-legged gulls that were brought to Mashhad Birds Garden (northeastern Iran) were examined visually for infestation with any ectoparasites and infestation with lice on the head zone was observed. The lice were collected and after clearing in aqueous solution of potassium hydroxide were mounted on slides. The morphological characteristics were used to identify 85 collected lice from three examined birds and they were identified as <em>Saemundssonia lari</em>. The lice of this species parasitize a broad range of host species and it seems to be less host specific. Iran has many aquatic habitats and a few lakes that host many migratory birds annually. The accumulation of these birds in these habitats could spread lice infestations among themselves that negatively affect their health and welfare. Therefore, Periodic checks to identify ectoparasites and other pathogens of migratory birds are quite necessary.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"57 ","pages":"Article 101149"},"PeriodicalIF":1.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
