Developing an apicomplexan dna barcoding system to detect blood parasites of small coral reef fishes
Renoux, Lance P.; Cook, Courtney A.; Smit, Nico J.; Sikkel, Paul C.; Dolan, Maureen C. (American Society of Parasitologists, 2017)Apicomplexan parasites are obligate parasites of many species of vertebrates. To date, there is very limited understanding of these parasites in the most-diverse group of vertebrates, actinopterygian fishes. While DNA ... -
The distribution and host-association of a haemoparasite of damselfishes (Pomacentridae) from the eastern Caribbean based on a combination of morphology and 18S rDNA sequences
Sikkel, Paul C.; Cook, Courtney A.; Smit, Nico J.; Renoux, Lance P.; Bennett, Courtney L. (Elsevier, 2018)Coral reefs harbor the greatest biodiversity per unit area of any ecosystem on earth. While parasites constitute the majority of this biodiversity, they remain poorly studied due to the cryptic nature of many parasites and ... -
First record of an intraleucocytic haemogregarine (Adeleorina: Haemogregarinidae) from South African tortoises of the species Stigmochelys pardalis (Cryptodira: Testudinidae)
Cook, Courtney A.; Smit, Nico J.; Davies, Angela J. (Taylor & Francis, 2014)To date, four intraerythrocytic apicomplexans, namely the haemogregarines Haemogregarina fitzsimonsi and Haemogregarina parvula, and the haemoproteids Haemoproteus testudinalis and Haemoproteus natalensis, have been described ... -
Hepatozoon species (Adeleorina: Hepatozoidae) of African bufonids, with morphological description and molecular diagnosis of Hepatozoon ixoxo sp. nov. parasitising three Amietophrynus species (Anura: Bufonidae)
Netherlands, Edward C.; Cook, Courtney A.; Smit, Nico J. (BioMed Central, 2014)Background Haemogregarines comprise a large group of apicomplexan blood parasites. In 1996 all anuran haemogregarines still in the genus Haemogregarina Danilewsky, 1885 were reassigned to the genus Hepatozoon Miller, ... -
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 ... -
A new lizard malaria parasite Plasmodium intabazwe n. sp. (Apicomplexa: Haemospororida: Plasmodiidae) in the Afromontane Pseudocordylus melanotus (Sauria: Cordylidae) with a review of African saurian malaria parasites
Van As, Johann; Cook, Courtney A.; Netherlands, Edward C.; Smit, Nico J. (BioMed Central, 2016)Background Saurian malaria parasites are diverse apicomplexan blood parasites including the family Plasmodiidae Mesnil, 1903, and have been studied since the early 1900s. Currently, at least 27 species of Plasmodium are ... -
Occurrence of Hepatozoon canis (Adeleorina: Hepatozoidae) and Anaplasma spp. (Rickettsiales: Anaplasmataceae) in black-backed jackals (Canis mesomelas) in South Africa
Penzhorn, Barend L.; Netherlands, Edward C.; Cook, Courtney A.; Smit, Nico J.; Vorster, Ilse (BioMed Central, 2018)Background: Domestic dogs are not native to sub-Saharan Africa, which may account for their susceptibility to Babesia rossi , of which endemic black-backed jackals ( Canis mesomelas ) are natural reservoirs. There is ... -
Reassignment of the land tortoise haemogregarine Haemogregarina fitzsimonsi Dias 1953 (Adeleorina: Haemogregarinidae) to the genus Hepatozoon Miller 1908 (Adeleorina: Hepatozoidae) based on parasite morphology, life cycle and phylogenetic analysis of 18S rDNA sequence fragments
Cook, Courtney A.; Lawton, Scott P.; Davies, Angela J.; Smit, Nico J. (Cambridge University Press, 2014)Research was undertaken to clarify the true taxonomic position of the terrestrial tortoise apicomplexan, Haemogregarina fitzsimonsi (Dias, 1953). Thin blood films were screened from 275 wild and captive South African ... -
Redescription and molecular diagnosis of Hepatozoon theileri (Laveran, 1905) (Apicomplexa: Adeleorina: Hepatozoidae), infecting Amietia quecketti (Anura: Pyxicephalidae)
Netherlands, Edward C.; Cook, Courtney A.; Smit, Nico J.; Du Preez, Louis H. (Praha : Academia, 2014)Blood smears prepared from the peripheral blood of 20 wild caught Amietia quecketti (Boulenger) from the North-West University Botanical Gardens, North West Province, South Africa, were examined for the presence of ... -
Redescription, molecular characterisation and taxonomic re-evaluation of a unique African monitor lizard haemogregarine Karyolysus paradoxa (Dias, 1954) n. comb. (Karyolysidae)
Cook, Courtney A.; Netherlands, Edward C.; Smit, Nico J. (BioMed Central, 2016)Background: Within the African monitor lizard family Varanidae, two haemogregarine genera have been reported. These comprise five species of Hepatozoon Miller, 1908 and a species of Haemogregarina Danilewsky, 1885. Even ... -
Ultrastructural comparison of Hepatozoon ixoxo and Hepatozoon theileri (Adeleorina: Hepatozoidae), parasitising South African Anurans
Conradie, Roxanne; Cook, Courtney A.; Du Preez, Louis H.; Jordaan, Anine; Netherlands, Edward C. (Wiley, 2017)To date, only two haemogregarine parasite species have been described from South African anurans: Hepatozoon ixoxo, infecting toads of the genus Scler- ophrys (syn. Amietophrynus); and Hepatozoon theileri, parasitising ...
