Prevalence rates of microsporidia in locusts and grasshoppers in South-Western Russia

BIO Web of Conferences, 2020
Locusts and grasshoppers are dangerous polyphagous pests of agricultural crops. In the present paper, results of screening of Acridoidea populations in the South-Western Russia for microsporidia infections including locusts Locusta migratoria ...

Human Microsporidial Infections [PDF]

, 2006
Microsporidia are eukaryotic, spore forming obligate intracellular parasites, first recognised over 100 years ago. Microsporidia are becoming increasingly recognised as infectious pathogens causing intestinal and extra-intestinal diseases in both immuno ...

Virulence Evolution: Thinking Outside of the Host

Evolutionary Applications, Volume 18, Issue 9, September 2025.
ABSTRACT The main theory of the evolution of virulence relies on a trade‐off between virulence and transmission rate. However, it has been difficult to measure the required trade‐off. A recent transmission decomposition framework explains that this might be partly due to a lack of information about the parasite's survival in the environment outside its

Molecular detection and phylogenetic analysis of microsporidia in water and soil in Mosul city

Open Veterinary Journal
Background: Microsporidia are opportunistic intracellular parasites that cause a variety of illnesses in humans. There is little information available regarding the frequency of these parasite in human cases of diarrhea and cancer.

Microsporidia detection and genotyping study of human pathogenic E. bieneusi in animals from Spain.

PLoS ONE, 2014
Microsporidia are ubiquitous parasites infecting all animal phyla and we present evidence that supports their zoonotic potential. Fecal samples taken from domestic (cats and dogs), farm (pigs, rabbits and ostriches) and wild animals (foxes) from ...

Pesticide and Pathogen Exposure Causes Idiosyncratic Gene Expression Responses Across Four Diverse North American Bumble Bee Species

Molecular Ecology, Volume 34, Issue 17, September 2025.
ABSTRACT Bumble bee (Bombus Latreille) populations of certain species have declined precipitously in North America over several decades. Hypotheses for declines include exposure to the pathogen Nosema bombi and neonicotinoid pesticides. Importantly, populations of some bumble bee species remain stable despite their presumed exposure to these same ...

Microsporidia persistence in host impairs epithelial barriers and increases chances of inflammatory bowel disease

Microbiology Spectrum
Microsporidia are intracellular fungus-like pathogens and the infection symptoms include recurrent diarrhea and systematic inflammations. The major infection route of microsporidia is the digestive tract.

First identification and genotyping of Enterocytozoon bieneusi and Encephalitozoon spp. in pet rabbits in China

BMC Veterinary Research, 2020
Background Microsporidia are common opportunistic parasites in humans and animals, including rabbits. However, only limited epidemiology data concern about the prevalence and molecular characterization of Enterocytozoon bieneusi and Encephalitozoon spp ...

Intestinal microsporidiosis: a new entity in Malaysia? [PDF]

, 2008
Objective: Intestinal microsporidia is an emerging human disease caused by microsporidia. A study was conducted to determine the prevalence of microsporidia in patients with gastro-intestinal symptoms and to examine the clinical manifestations associated

Strong Bottlenecks Constrain Adaptive Coevolution in a Host–Parasite Metapopulation

Molecular Ecology, Volume 34, Issue 17, September 2025.
ABSTRACT Although parasites are well‐known for adaptively evolving in order to exploit their hosts, they may experience strong genetic drift during transmission bottlenecks when infecting a new host. Host population structure and host population bottlenecks can also lead to genetic drift effects in parasite populations, constraining their adaptive ...
