Checklist of acanthocephalan parasites of South Africa

Halajian, Ali; Smit, Nico J.; Smales, Lesley R.; Tavakol, Sareh; Luus-Powell, Wilmien J. (Pensoft, 2018)

Twenty-one species of acanthocephalans, representative of thirteen genera from ten families of seven orders and three classes, are included in this updated checklist of acanthocephalans in South Africa. Although South ...

Diurnal activity patterns of the temporary fish ectoparasite, Gnathia africana Barnard, 1914 (Isopoda, Gnathiidae), from the southern coast of South Africa

Welicky, Rachel L.; Sikkel, Paul; Smit, Nico J.; Ferreira, Maryke L. (Cambridge Univ Press, 2018)

Gnathiid isopods are one of the most common fish ectoparasites, and are found in both temperate and tropical oceans. On coral reefs, gnathiids are most active at dusk and dawn, and contribute significantly to trophic ...

Investigation of mRNA expression changes associated with field exposure to DDTs in chickens from KwaZulu-Natal, South Africa

Thompson, Lesa A.; Ikenaka, Yoshinori; Van Vuren, Johan J.; Wepener, Victor; Smit, Nico J. (PLoS, 2018)

The objective of this study was to identify potential mRNA expression changes in chicken livers associated with environmental exposure to dichloro-diphenyl-trichloroethane (DDT) and its metabolites (DDTs). In particular, ...

Linking organochlorine exposure to biomarker response patterns in Anurans: a case study of Müller’s clawed frog (Xenopus muelleri) from a tropical malaria vector control region

Wolmarans, Nico J.; Du Preez, Louis H.; Ikenaka, Yoshinori; Smit, Nico J.; Wepener, Victor (Springer, 2018)

Organochlorine pesticides are highly persistent in aquatic ecosystems. Amphibians, specifically anurans, play an intricate part in the aquatic food web, and have very permeable skin which makes them prone to bioaccumulation ...

Monophyly of the species of Hepatozoon (Adeleorina: Hepatozoidae) parasitizing (African) anurans, with the description of three new species from hyperoliid frogs in South Africa

Netherlands, Edward C.; Cook, Courtney A.; Du Preez, Louis H.; Brendonck, Luc; Smit, Nico J. (Cambridge Univ Press, 2018)

Haemogregarines (Apicomplexa: Adeleiorina) are a diverse group of haemoparasites reported from almost all vertebrate classes. The most commonly recorded haemogregarines to parasitize anurans are species of Hepatozoon ...

DNA barcoding of the medically important freshwater snail Physa acuta reveals multiple invasion events into Africa

Lawton, Scott P.; Smit, Nico J.; Allan, Fiona; Hayes, Polly M. (Elsevier, 2018)

The medically important freshwater snail Physa acuta is highly invasive and has been reported in several freshwater environments across Africa. To identify species and provide initial insights into the origins of P. acuta ...

Molecular insights into the identification and phylogenetics of the cosmopolitan marine fish blood parasite, Haemogregarina bigemina (Adeleorina: Haemogregarinidae)

Hayes, Polly M.; Smit, Nico J. (Elsevier, 2019)

Haemogregarina bigemina is one of the most prevalent haemogregarines of marine fishes and has long been considered an enigmatic and cosmopolitan species. However, to determine whether H. bigemina truly represents a single ...

Revision of the fish parasitic genus Pleopodias Richardson, 1910 (Isopoda, Cymothoidae), with the description of a new species and key to the genus

Hadfield, Kerry A.; Smit, Nico J. (Pensoft, 2017)

The cymothoid genus, Pleopodias Richardson, 1910, is revised and a new species from South Africa is recorded. Pleopodias nielbrucei sp. n. can be distinguished by large eyes covering majority of the cephalon (almost in ...

Redescription of poorly known species of Ceratothoa Dana, 1852 (Crustacea, Isopoda, Cymothoidae), based on original type material

Hadfield, Kerry A.; Bruce, Niel L.; Smit, Nico J. (Pensoft, 2016)

Due to the difficulty in accurately identifying cymothoids, these parasitic isopods are often incorrectly named or confused with other species. Within the genus Ceratothoa, a number of recent studies have aimed at ...

Elthusa nierstraszi nom. n., the replacement name for Elthusa parva (Nierstrasz, 1915), a junior secondary homonym of Elthusa parva (Richardson, 1910) (Isopoda, Cymothoidae)
