Abstract Haemogregarina macrochelysi n. sp. (Apicomplexa: Haemogregarinidae) of the alligator snapping turtle, Macrochelys temminckii, is characterized by slender, recurved gamonts 29–35 × 3–4.5 μm, in which the anterior limb comprises 48–54% of the total length. The gamont nucleus, 5–7.5 × 2–5 μm, is situated at approximately midbody of the gamont. Meronts typical of Haemogregarina occupying erythrocytes have 3-8 small, compact nuclei and are 13–17 × 4.5–9 μm. Erythrocytic meronts that contain… Expand
Molecular and morphological characterization of a haemogregarine in the alligator snapping turtle, Macrochelys temminckii (Testudines: Chelydridae)
TLDR
A severely underweight alligator snapping turtle Macrochelys temminckii Troost in Harlan, 1835, was found near Tyler, Texas, and taken to the Caldwell Zoo, and morphology and morphometric data for the forms indicate similarity to Haemogregarina macrochelysi n. Expand
Molecular characterisation of Hepatozoon aegypti Bashtar, Boulos & Mehlhorn, 1984 parasitising the blood of Spalerosophis diadema (Serpentes: Colubridae)
TLDR
Phylogenetic analysis based on the partial 18S small subunit ribosomal DNA sequences indicates that Hepatozoon aegypti cluster within a mixed clade of HepatoZoon species parasitising snakes, geckos and rodents from various geographic areas. Expand
Haemogregarines of freshwater turtles from Southeast Asia with a description of Haemogregarina sacaliae sp. n. and a redescription of Haemogregarina pellegrini Laveran and Pettit, 1910
TLDR
The incompleteness of the morphological data and relatively low host specificity provides the space for large synonymy within this taxon, so a complex approach combining microscopic analyses together with molecular-genetic methods should represent the basic standard for all taxonomic studies. Expand
Biodiversity of the Coccidia (Apicomplexa: Conoidasida) in vertebrates: what we know, what we do not know, and what needs to be done.
Over the last two decades my colleagues and I have assembled the literature on a good percentage of most of the coccidians (Conoidasida) known, to date, to parasitise: Amphibia, four major lineagesExpand
Tracking platyhelminth parasite diversity from freshwater turtles in French Guiana: First report of Neopolystoma Price, 1939 (Monogenea: Polystomatidae) with the description of three new species
TLDR
Three new polystomes from the hosts K. scorpioides and R. punctularia are described, being the first chelonianpolystomes to be reported and described from French Guiana and the first representatives of Neopolystoma from South America. Expand
Haemogregarines and Criteria for Identification
TLDR
PCR-based assays and the sequencing of the 18S rRNA gene are helpful methods to further characterize this parasite group and the proper classification for the haemogregarine complex is available with the criteria of generic and unique diagnosis of these parasites. Expand
Molecular detection of hemogregarines and haemosporidians in Brazilian free-living testudines
TLDR
The findings suggest that free-living P. expansa were parasitized by a new genotype or even a possible new species of the genus Haemogregarina, and five closely related genotypes that formed a monophyletic group were revealed. Expand
Molecular detection of Apicomplexan hemoparasites in anurans from Brazil
TLDR
This study showed, for the first time, the molecular detection of Lankesterella sp. Expand
Population Structure and Body Size of the Suwannee Alligator Snapping Turtle (Macrochelys suwanniensis) in Northern Florida
TLDR
The M. suwanniensis population in the SFR presently appears healthy, but it is suggested this species requires continued protection because of vulnerability of adults to harvest. Expand
Identification of Blood Parasites in Individuals from Six Families of Freshwater Turtles
TLDR
Wild turtles would be more likely sources of parasite transmission to captive populations if used in breeding programs, and captive breeding with subsequent release of turtles would seem to pose little risk to free-ranging turtles with regard to the spread of these parasites. Expand

Prevalence and intensity of Haemogregarina balli (Apicomplexa: Adeleina: Haemogregarinidae) in three turtle species from Ontario, with observations on intraerythrocytic development
TLDR
Free-ranging populations of turtles, Chelydra serpentina serpentina, Chrysemys picta marginata, and Clemmys insculpta, were examined for prevalence and intensity of Haemogregarina balli during the summers of 1989 and 1990 in Algonquin Park, Ontario to suggest that the biology of P. ornata is an important influence in these changes.

TLDR
In Florida, at least, the diversity of the Hepatozoon community not only equals but probably exceeds the Diversity of the snake communities present, and that host specificity in nature may be much greater than that postulated from previous studies. Expand
