For parasites that live within the host, part of the reason for this lack of information is that the hosts must be killed and dissected to determine which endoparasites they harbour, which has legal and/or ethical implications and limitations. These obstacles can be overcome by collecting and examining potential hosts that are found dead on roads or that are sacrificed as part of other non-related studies. In this study, our objective was to expand on our understanding of the gastrointestinal parasites of some common reptiles from an area in the vicinity of a study site in the Mid North region of South Australia by making use of snakes and large lizards that were found dead on roads or that were humanely killed for another study. Our study provides new locality and/or host species records for some parasite species.

Recently, limited work has been published on some ectoparasites of Arkansas rodents (McAllister et al. 2013, Tumlison et al. 2015). Here, we report information on a coccidian and some ectoparasites collected from rodents in the state. Pocket gophers from Arkansas were collected as follows and examined for helminths and coccidian parasites: 10 Ozark pocket gophers (Geomys bursarius ozarkensis) were collected

Fourteen toads (78%) were infected or infested with parasites as follows: 2 (11%) with Megalodiscus temperatus, 1 (6%) with tetrathyridia of Mesocestoides sp., 3 (17%) with Cylindrotaenia americana, 2 (11%) with 3rd-stage larval Physaloptera sp., 9 (50%) with Cosmocercoides variabilis, 10 (55%) with Oswaldocruzia pipiens, and 2 (11%) with larval Hannemania hegeneri chigger mites. We observed multiple infections/infestations of helminths and/or arthropods in 7 (39%) of these hosts. Herein, we report 5 new host and 2 new geographic-distribution records.

All 20 frogs harbored with one or more species, including 13 each (65%) with Opalina sp., and Nyctotherus cordiformis, 10 (50%) with Cystodiscus melleni, three (15%) with unknown reniferid metacercaria, three (15%) with Mesocoelium sp., one (5%) with Cylindrotaenia americana, four (20%) with Oswaldocruzia leidyi, five (25%) with Cosmocercoides variabilis, and three (15%) with unidentified acuariid larva. All (100%) harbored two or more protists, a cnidarian and/or helminths each. The Mesocoelium sp. appears to be a new species and new host records are reported for it as well as reniferid metacercaria; new distributional records in the state are documented for N. cordiformis, C. melleni, Mesocoelium sp. and O. leidyi.

Methods Digeneans were fixed in AFA (alcohol–formalin–acetic acid), stained with Borax’s carmine, studied and photomicrographed with a BX53 DIC/BF Olympus research microscope. Molecular studies were done by DNA isolation using Qiagen, DNeasy® Blood and Tissue Kit and PCR amplification using r-DNA ITS-1 marker situated between 18S and 1.58S gene. Results and conclusion The new species is differentiated from other known species of Haematoloechus in having larger oral sucker, kidney-shaped ovary and oval-lobed testes. H. singaporensis collected from E. cyanophlyctis represents a first record for India and a new host record. ITS sequences submitted and compared at NCBI GenBank support the uniqueness of the new species.

Thirty-seven of 74 (50%) E. tynerensis were found to harbor Sphyranura euryceae. Fifteen of 25 (60%) of the E. tynerensis in the far-downstream section were infested by S. euryceae, 8 of 31 (26%) of the middownstream Oklahoma salamanders were infested, and 14 of 19 (78%) of the near-downstream E. tynerensis had the highest prevalence of S. euryceae. Analyses of variance with Fisher's least significant difference test of mean intensity of S. euryceae on E. tynerensis showed significant variation among groups. One of 2 (50%) E. spelaea from the neardownsteam section harbored S. euryceae; none of the 10 E. spelaea from the pond inlet were infested. We report the first population study of S. euryceae in E. tynerensis and a new host record for this monogenoidean in E. spelaea.
