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

open access: yesEcology 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 ...

Goussia trichogasteri n. sp. (Apicomplexa: Eimenidae) infecting the aquarium-cultured golden gourami Trichogaster trichopterus trichopterus [PDF]

open access: yes, 1992
Goussia trichogasteri n. sp. is described from the gut of the aquarium fish Trichogaster trichopterus trichopterus. Gamogonic stages develop epicellularly in the gut epithelium. Oocysts are shed in early stage of sporulation.

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

open access: yesIntegrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Identification of novel cryptosporidium genotypes from the Czech Republic [PDF]

open access: yes, 2003
Isolates of Cryptosporidium from the Czech Republic were characterized from a variety of different hosts using sequence and phylogenetic analysis of the 18S ribosomal DNA and the heat-shock (HSP-70) gene.

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

open access: yesVeterinary 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 ...

Neospora caninum and Bovine Neosporosis: Current Vaccine Research [PDF]

open access: yes, 2017
Neospora caninum, a tissue cyst-forming parasite, is the causative agent of bovine neosporosis. It is considered to be one of the most important transmissible causes of reproductive failure in cattle; abortion and neonatal mortality result in significant

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

open access: yesVeterinary 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.

Divergent polyamine metabolism in the Apicomplexa [PDF]

open access: yesMicrobiology, 2007
The lead enzymes of polyamine biosynthesis, i.e. ornithine decarboxylase (ODC) and arginine decarboxylase (ADC), were not detected in Toxoplasma gondii [the limit of detection for ODC and ADC was 5 pmol min(-1) (mg protein)(-1)], indicating that T. gondii lacks a forward-directed polyamine biosynthetic pathway, and is therefore a polyamine auxotroph ...

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3103-3113, June 2026.
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...
