We collected a total of 3,783 helminths belonging to 13 taxa: 4 digenean, 1 cestode, 1 acanthocephalan, and 7 nematoda. The nematode Physocephalus sp. was the most prevalent (63.3%) followed by Aplectana sp., which had the highest mean intensity (114.3) and mean abundance (63.8) that we recorded. The taxonomic composition of I. marmoreus mainly consists of generalist helminths, with nematodes being the predominant parasites found, confirming the terrestrial habits of this toad. The main route of helminth acquisition was ingestion of larvae and/or intermediate hosts, a process that also likely contributes to the high abundance of individuals in the toads. The knowledge of the helminth fauna associated to the 39 toad species distributed in Mexico is scarce and fragmentary, and our study presents results for only the second bufonid species studied in this region.","PeriodicalId":214905,"journal":{"name":"New Data on Myxobolus enoblei (Cnidaria: Myxobolidae): A Parasite of Smallmouth Buffalo Ictiobus bubalus (Cypriniformes: Catostomidae)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130696963","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 objective of this study is to report for first time the infection by A. cf. pacificus in the anadromous Coho salmon, Oncorhynchus kisutch, from the Simpson River, Chile. During July 1997 and July 1998, the fish were examined for diphyllobothriidean parasites. The plerocercoids were found encysted in the stomach, peritoneum, liver, spleen, gonads, and muscles. The prevalence of infection fluctuated between 75.0 and 100% and the mean intensity was between 31.6 ± 25.4 and 34.9 ± 27.9 plerocercoids in July 1997 and July 1998, respectively. The frequency of plerocercoids in the muscles was 15.6 to 20.0%, respectively, and the mean was 0.3–0.4 plerocercoids/infected fish. Eight adult dogs were submitted to fecal exams and treated with a broad-spectrum antiparasitic. Six of 8 dogs were successfully orally infected by freshly obtained plerocercoids. Two of them ingested 40 plerocercoids, and we recovered between 34 and 32 cestodes at 21 and 27 d postinfection (DPI), respectively; we identified only 3 gravid specimens in the last dog and the rest of the worms were nongravid. The other dogs presented between 1 and 4 cestodes at 29 and 44 DPI. The prepatent period fluctuated between 21 and 28 DPI and the gravid cestodes measured between 24 and 104 cm long.

These activities extended from descriptive morphology of protists, fungi and insects to the biochemistry of respiratory enzymes and metallo-protein compounds. It is, consequently, not possible for one person to deal adequately with all aspects of his work and in this appreciation of the man and his scientific achievements the main emphasis will be on his biological work. That bearing on parasitology will be considered in some detail, whereas the later, more biochemical, work will be considered briefly as fuller accounts of it have already been given by E. F. Hartree (Biochem. J. 89, 1-5), T. R. R. Mann (Biogr. Mem. Fellows B. Soc. 10, 185-207) and E. C. Slater (Enzymologia, 26, 313-20). In the brief survey of his biochemical work I have made much use of summaries and reports written by Keilin himself and I have often given the essence of lines of work summed up in his own words which express his conclusions with the elegance, lucidity and brevity characteristic of his style. As I was closely associated with David Keilin and in almost daily contact with him for just on forty years, it is natural that the following account will to some extent reflect my own interests and those aspects of his personality which became manifested during long and intimate contact both in private life and collaboration in scientific and administrative work.","PeriodicalId":214905,"journal":{"name":"New Data on Myxobolus enoblei (Cnidaria: Myxobolidae): A Parasite of Smallmouth Buffalo Ictiobus bubalus (Cypriniformes: Catostomidae)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1913-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129692397","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}
