Coccidian oocysts

Parasitology, 1944
1. The spores of Eimeria (not the oocysts) are the real infective agents and, as in other Sporozoa, they readily set free their sporozoites in the duodenum or in vitro under suitable conditions.2. The protective oocyst has double walls: the ectocyst is thick and impervious to fluids but easily fractures by mechanical means, such as drying.

The Potential of Bioinformatics in Revolutionizing Disease Diagnosis in Sub‐Saharan Africa: A Narrative Review

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aim Despite its role in healthcare delivery and accessibility, the potential of bioinformatics to transform disease diagnosis in SSA remains unknown. This narrative review aims to assess the current status of bioinformatics initiatives in SSA and evaluate the role of bioinformatics in transforming diagnosis of major diseases in ...

Morphological and Molecular Characterization of Eimeria spp. Infecting Domestic Poultry Gallus gallus in Riyadh City, Saudi Arabia

Microorganisms, 2023
Coccidiosis in chickens is one of the major problems in the poultry industry, caused by protozoan parasites of the genus Eimeria. The current study used morphological and molecular characteristics to identify Eimeria spp.

Molecular and Biological Characterization of a Cryptosporidium molnari-Like Isolate from a Guppy (Poecilia reticulata) [PDF]

, 2004
Histological, morphological, genetic, and phylogenetic analyses of a Cryptosporidium molnari-like isolate from a guppy (Poecilia reticulata) identified stages consistent with those of C. molnari and revealed that C.

Simulated Microgravity Causes Faster Replication During Acute Infection of ME49‐Toxoplasma Gondii and Alterations in Host Cells

FASEB BioAdvances, Volume 8, Issue 4, April 2026.
Simulated microgravity (SMG) alters the growth and morphology of host cells and induces parasite replication during acute T. gondii infection. In this study, we examined host cells and Type II T. gondii using a 3D clinostat. Increased number of host cells and multicellular spheroids observed in Vero cells and HFF.

Population biology of Toxoplasma gondii: what's out and where did they come from

Memorias do Instituto Oswaldo Cruz, 2009
Until recently, Toxoplasma gondii was considered to be clonal with little genetic variability. In this paper we summarize recent genotyping data from chickens in Brazil, and pigs, lambs and white-tailed deer in the USA, to demonstrate the high genetic ...

Effects of Feed Additives and Mixed Eimeria Species Infection on Intestinal Microbial Ecology of Broilers [PDF]

, 2006
Evaluation of digestive microbial ecology is necessary to understand effects of growth-promoting feed. In the current study, the dynamics of intestinal microbial communities (MC) were examined in broilers fed diets supplemented with a combination of ...

Nanoparticle Lysis of Cryptosporidium Oocysts

Methods and Protocols
The extraction of DNA from Cryptosporidium oocysts is challenging due to the robust oocyst wall. Nanoparticles have been applied to disinfect Cryptosporidium oocysts; here, we demonstrate the utilisation of nanoparticles to disrupt the oocyst wall to enable sporozoite lysis and detection via PCR.

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Effect of sulphuric acid and formalin on sporulation of Eimeria bovis oocysts

Kufa Journal for Veterinary Medical Sciences, 2011
Eimeria bovis oocysts were isolated and identified after obtained the fecal sample from infected calf.     Three different concentrations of sulphuric acid and of formalin were examining to observe their effect on E.bovis oocysts sporulation in ...
