Droplet digital PCR as a tool for investigating dynamics of cryptic symbionts

Ecology and Evolution, 2021
Interactions among symbiotic organisms and their hosts are major drivers of ecological and evolutionary processes. Monitoring the infection patterns among natural populations and identifying factors affecting these interactions are critical for ...

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Characterization of mRNA polyadenylation in the apicomplexa

PLOS ONE, 2018
Messenger RNA polyadenylation is a universal aspect of gene expression in eukaryotes. In well-established model organisms, this process is mediated by a conserved complex of 15-20 subunits. To better understand this process in apicomplexans, a group of unicellular parasites that causes serious disease in humans and livestock, a computational and high ...

Identification of Lupus Erythematosus Cells and Ragocytes in Peripheral Blood from a Dog with Systemic Lupus Erythematosus

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 3‐year‐old female‐intact German Shepherd presented for the evaluation of progressive shifting leg lameness, carpal swelling, and weight loss with a poor appetite since adoption about three months prior. Routine blood smear evaluation, lymph node, and synovial fluid cytologies all revealed rare neutrophils with cytoplasmic inclusions ...

Infection with the Neorickettsial Organism Stellantchasmus falcatus Agent in an Arctic Fox (Vulpes lagopus)

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 1‐year‐old female‐intact arctic fox (Vulpes lagopus) presented for diarrhea, lethargy, severe thrombocytopenia, and hyperbilirubinemia. Blood film evaluation revealed intracytoplasmic coccoid bacteria within moderate numbers of leukocytes consistent with infection by a rickettsial organism.

Prospects for elucidating the phylogeny of the Apicomplexa [PDF]

Parasite, 2008
The Apicomplexa is traditionally considered to contain four clearly defined groups, but the phylogenetic relationships among these groups, and their subsequent taxonomic arrangement, are currently unclear. Here, I consider five of the important criteria that need to be met before radical taxonomic changes are made, in relation to phylogenetic analyses.

Survey of Gastrointestinal Parasites of Farmed Pigs in Ghana

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Survey of Gastrointestinal Parasites of Farmed Pigs in Ghana Gastrointestinal parasites were common in pigs sampled from Kpone Katamanso Municipality, Ghana, with an overall prevalence of 67.6%. Complementary formol–ether concentration, modified McMaster, and modified Ziehl–Neelsen techniques improved parasite detection, while polymerase chain reaction

The Genus Hepatozoon (Apicomplexa: Adeleina) [PDF]

The Journal of Parasitology, 1996
Hemogregarines of the genus Hepatozoon are intraerythrocytic apicomplexan parasites that have been described from all groups of tetrapod vertebrates. Gametogenesis, fertilization, and sporogonic development, which culminates in the formation of polysporocystic oocysts, occur in the gut or hemocoel of a hematophagous arthropod definitive host. Merogonic
