Blood parasites of the genus Hepatozoon (Apicomplexa, Hepatozoidae) infect all groups of terrestrial vertebrates, and particularly high prevalence and species diversity have been reported in reptiles and mammals. [...] Key Result Hepatozoon ellisgreineri n. sp. can be readily distinguished from all described species of avian Hepatozoon because its gamonts develop only in granulocytes, predominantly in heterophils, a unique characteristic among bird parasites of this genus.Expand
Lankesterella (Apicomplexa, Lankesterellidae) Blood Parasites of Passeriform Birds: Prevalence, Molecular and Morphological Characterization, with Notes on Sporozoite Persistence In Vivo and Development In Vitro
A high diversity of Lankesterella parasites in birds is demonstrated, and it is demonstrated that several avian Hepatozoon-like parasites, in fact, belong to Lankestere genus, which is more diverse than previously thought. Expand
Molecular and morphological description of the first Hepatozoon (Apicomplexa: Hepatozoidae) species infecting a neotropical turtle, with an approach to its phylogenetic relationships
A new Hepatozoon species is reported that represents the first report of a hepatozoid species infecting a semi-aquatic continental turtle in the world and is important to identify new molecular markers to improve parasite species identification. Expand
Redescription of Hepatozoon ameivae (Carini and Rudolph, 1912) from the lizard Ameiva ameiva (Linnaeus, 1758)
Blood samples from 72 Ameiva ameiva lizards from Central Amazonian upland forests were collected, and thin smears of 40 animals were positive for gamonts of Hepatozoon with a mean level of intensity of infection of 14 parasites/2000 blood erythrocytes, which provides the first molecular characterization of a HepatoZoon species from a Brazilian lizard.

Hemogregarine parasites in wild captive animals, a broad study in São Paulo Zoo
The purpose of this study was to gather information from the database available at the Clinical Analyses Laboratory at São Paulo Zoo Foundation in the last ten years and determine the occurrence of hemogregarine parasites in captive animals of the SãoPaulo Zoo Foundation. Expand
Further characterisation of Leucocytozoon podargii in wild tawny frogmouths (Podargus strigoides) in Western Australia
It was concluded that the Leucocytozoon parasite identified from wild tawny frogmouths in WA is consistent with L. podargii in wild tAWS from WA and Queensland and genetically characterised two different L.podargii genotypes (QLD and WA) for the first time. Expand


First Molecular Characterization of a Hepatozoon Species (Apicomplexa: Hepatozoidae) Infecting Birds and Description of a New Species Infecting Storm Petrels (Aves: Hydrobatidae)
This is the first Hepatozoon species infecting birds to be characterized at the molecular level and the first found infecting erythrocytes and not leucocytes. Expand
The genus Hepatozoon (Apicomplexa: Adeleina).
  • T. G. Smith
  • Biology, Medicine
  • The Journal of parasitology
  • 1996
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. Expand
Redescription of Hepatozoon felis (Apicomplexa: Hepatozoidae) based on phylogenetic analysis, tissue and blood form morphology, and possible transplacental transmission
The results indicate that feline infection is primarily caused by a morphologically and genetically distinct species, H. felis, which has predilection to infecting muscular tissues, and is highly prevalent in the cat population studied. Expand
Characterization of Hepatozoon spp. in Leptodactylus chaquensis and Leptodactylus podicipinus from two regions of the Pantanal, state of Mato Grosso do Sul, Brazil
Although the morphology and morphometry of the collected parasites at each site showed differences, the sequencing of these samples revealed identical species of Hepatozoon, and different compared to those from GenBank, thereby demonstrating that the species in L. chaquensis observed in this study probably represent a new species. Expand
Molecular characterization of putative Hepatozoon sp. from the sedge warbler (Acrocephalus schoenobaenus)
Partial sequences of 18S rDNA from sedge warblers infected with a parasite described previously as Hepatozoon kabeeni are characterized, supporting the suggestion that the systematic position of avian HepatoZoon-like species needs to be revised. Expand
Description of gamontogonic and sporogonic stages of Hepatozoon spp. (Apicomplexa, Hepatozoidae) from Caudisoma durissa terrifica (Serpentes, Viperidae)
It is concluded that three types of gamonts were very similar and may represent the same Hepatozoon species, but at least three different HepatoZoon species were infecting the C. durissa terrifica snakes in this study. Expand
Molecular characterization of five widespread avian haemosporidian parasites (Haemosporida), with perspectives on the PCR-based detection of haemosporidians in wildlife
This study indicates that morphological characters, which have been traditionally used in taxonomy of avian haemosporidian parasites, have a phylogenetic value. Expand
Anurans as paratenic hosts in the transmission of Hepatozoon caimani to caimans Caiman yacare and Caiman latirostris
Results suggest these amphibians are paratenic hosts in the natural transmission cycle of H. caimani in Pantanal, suggesting that the main transmission route is through ingestion of insectivorous vertebrates, such as anurans. Expand
Recent advances in the study of avian malaria: an overview with an emphasis on the distribution of Plasmodium spp in Brazil.
This review discusses several emerging topics related to the current research of avian Plasmodium spp and some related avian haemosporidians and summarize some important discoveries in this field and emphasizes the value of using both polymerase chain reaction-based and microscopy-based methods in parallel for wildlife studies.
