Both DNA sequence data and morphologic and life-cycle characters support a sister-group relationship between H. americanum and H. canis and support elevating Hepatozoon to familial level (Hepatozoidae) as originally suggested by Wenyon in 1926.

Molecular survey and microscopic examination of Hepatozoon Miller, 1908 (Apicomplexa: Adeleorina) in lacertid lizards from the western Mediterranean.

Phylogeny based on 18S rRNA gene sequences indicates that most of the new Hepatozoon sequences are part of a clade exclusive from North African and Iberian lizards, except for a single P bocagei isolate that is found related to another clade including isolate from other reptile host species and rodents.

Hepatozoon milleri sp. nov. (Adeleorina: Hepatozoidae) in Akodon montensis (Rodentia: Cricetidae: Sigmodontinae) from southeastern Brazil

This is the first description of a new Hepatozoon species from wild small rodents in Brazil, based on morphological and molecular characteristics, and detected in this study is distinct from those species previously reported in small rodents.

Description of a New Species Hepatozoon quagliattus sp. nov. (Apicomplexa: Adeleorina: Hepatozoidae), infecting the Sleep Snake, Dipsas mikanii (Squamata: Colubridae: Dipsadinae) from Goiás State, Brazil

A new species of Hepatozoon found infecting the sleep snake Dipsas mikanii from Brazil is described based on morphological and molecular data.

Developmental stages and molecular phylogeny of Hepatozoon fitzsimonsi (Dias 1953) (Adeleorina: Hepatozoidae) in tortoises Stigmochelys pardalis (Cryptodira: Testudinidae) and ticks of the genus Amblyomma (Acari: Ixodidae) from South Africa

The present study provides further support for ticks acting as the vectors of H. fitzsimonsi by molecularly identifying and linking observed developmental stages in tortoises with those in the invertebrate host ( Amblyomma spp).

Description of three new species of Hepatozoon (Apicomplexa, Hepatozoidae) from Rattlesnakes (Crotalus durissus terrificus) based on molecular, morphometric and morphologic characters.

Phylogenetic relationships of Hepatozoon (Haemogregarina) boigae, Hepatozoon sp., Haemogregarina clelandi and Haemoproteus chelodina from Australian reptiles to other Apicomplexa based on cladistic analyses of ultrastructural and life-cycle characters

The phylogeny of representative haemozoan species of the phylum Apicomplexa was reconstructed by cladistic analyses of ultrastructural and life-cycle characteristics, finding some relationship between parasites and their intermediate hosts, suggestive of parasite/vector co-evolution.

NEW MOLECULAR DATA ON MAMMALIAN HEPATOZOON SPECIES (APICOMPLEXA: ADELEORINA) FROM BRAZIL AND SPAIN

Phylogenetic analysis showed Hepatozoon to be a monophyletic genus, in which species from carnivorous mammals appear as a sister lineage of that of lower vertebrates and rodents, which suggests that H. americanum evolved in ticks and carnivores rather than in other ectoparasites and other types of mammal.

Molecular characterisation and morphological description of two new species of Hepatozoon Miller, 1908 (Apicomplexa: Adeleorina: Hepatozoidae) infecting leukocytes of African leopards Panthera pardus pardus (L.)

This paper describes two new haemogregarines in captive and wild leopards from South Africa and provides a tabular summary of these species in relation to species of Hepatozoon reported from mammalian carnivores.

The first report of Hepatozoon sp. (Apicomplexa: Hepatozoidae) in neotropical felids from Brazil.

Morphological and molecular characteristics of a species of Hepatozoon Miller, 1908 (Apicomplexa: Adeleorina) from the blood of Isoodon obesulus (Marsupialia: Peramelidae) in Western Australia

Phylogenetic analysis has not previously been reported for any species of Hepatozoon from Australian marsupials and consequently could not be used to confirm the identity of the organism in the current study as that described in the 1900s.

Correlation between parasite phylogeny and taxonomic affinities of their definitive hosts suggests that the definitive hosts of heteroxenous sporozoa are their ancestral hosts.

The genus Hepatozoon (Apicomplexa: Adeleina).

A systematic review of the hemogregarine complex has resulted in the expansion in the genus Hepatozoon to include all members of the genus Haemogregarina that infect amphibians, snakes, lizards, crocodilians, birds, and mammals.

Cryptosporidium is more closely related to the gregarines than to coccidia as shown by phylogenetic analysis of apicomplexan parasites inferred using small-subunit ribosomal RNA gene sequences

The trees indicate that the genus Cryptosporidium has a closer phylogenetic affinity with the gregarines than with the coccidia, and these results do not support the present classification of the cryptosporidiidae in the suborder Eimerioirina Léger, 1911.

An Eimeriid origin of isosporoid coccidia with Stieda bodies as shown by phylogenetic analysis of small subunit ribosomal RNA gene sequences.

Findings indicate that the genus Isospora as defined by several authors is polyphyletic, and species with StiedA bodies should be classified in the family Eimeriidae, whereas those without Stieda bodies should remain in theFamily Sarcocystidae.

Some corrections in Haemogregarine (Apicomplexa: Protozoa) nomenclature.

The nomenclature of three genera in the family Haemogregarina, Karyolysus, and Hepatozoon has been reviewed and the following new names are introduced to replace homonyms or for previously unnamed species.

Phylogenetic relationships between Toxoplasma and Sarcocystis deduced from a comparison of 18S rDNA sequences

The results obtained from this study do not reject the hypothesis of monophyly of Sarcocystis species, although the bootstrap data were inconclusive for some species.

Evolutionary origin of Plasmodium and other Apicomplexa based on rRNA genes.

The evolutionary history of the Apicomplexa and two related protistan phyla, Dinozoa and Ciliophora, is explored by comparing the nucleotide sequences of small subunit ribosomal RNA genes, and it is concluded that the Plasmodium lineage diverged from other apIComplexan lineages several hundred million years ago.
