Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Changes to Neuron Number

Evolution &Development, Volume 28, Issue 2, June 2026.
“Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Addition and Loss of Neurons” Han et al. DAPI staining of Xiphinema sp. (Clade 2) highlighting the neuronal‐like nuclei within the ventral nerve cord. ABSTRACT Despite their diversity in habitats, nematodes are often considered to have a highly conserved neuroanatomy.

Lungworms (Metastrongylus spp.) demonstrated in domestic pigs with respiratory disease: was there a clinical relevance?

Porcine Health Management, 2022
Background An outdoor pig herd was affected by severe respiratory disease in one out of three pastures. At necropsy, Mycoplasma hyopneumoniae and Pasteurella multocida were detected in the lungs, as well as the lung worm Metastrongylus apri.

Chronic Cholestatic Liver Disease Induced by Larval Ascariasis: Novel Insights Into Immune‐Mediated Pathogenesis and Hepatic Fibrosis in Mice

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Liver alterations induced by single infection (SI) or reinfection (RE) with 250 or 2500 Ascaris suum eggs in mice. Histological analysis shows inflammatory cell infiltration (eosinophils, lymphocytes, macrophages, and neutrophils), fibrotic areas, and bile duct proliferation in infected animals compared with uninfected controls.

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review

Chemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

A Scoping Review of the Associations Between Ascariasis, Helicobacter pylori Infection and Gastric Pathologies

Parasite Immunology, Volume 48, Issue 5, May 2026.
ABSTRACT Ascaris infection—ascariasis—is the most common human parasitic worm infection worldwide and induces damage and cellular changes within the stomach. Helicobacter pylori is a bacterium of the stomach that also causes gastric pathologies globally. Importantly, Ascaris, H.

Escherichia coli Nissle 1917 Occupies Previously Undocumented Host Niches in the Insect‐Parasitic Nematode Steinernema hermaphroditum

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This study characterizes previously undocumented host tissues in Steinernema nematodes, including putative coelomocytes, intestinal compartments, and inter‐cuticular spaces colonized by Escherichia coli Nissle 1917. Our findings reveal niche‐specific microbial interactions distinct from those with native symbionts, establishing a platform for ...

Exploring poly‐L‐lysine‐based particle capture for atomic force microscopy studies of extracellular vesicles

Journal of Microscopy, Volume 302, Issue 1, Page 100-110, April 2026.
Abstract We herein investigate the effects of varying the main experimental variables in one of the most used protocols for extracellular vesicle (EV) immobilisation on substrates for subsequent atomic force microscopy (AFM) quantitative morphometry and nanoindentation performed in liquid. We introduce the parameter Q as a quantitative measure of total

Hybrid and/or mixed infection by pig and human Ascaris in a Guarani indigenous village in southern Brazil.

PLoS Neglected Tropical Diseases
BackgroundAscaris lumbricoides and Ascaris suum are nematode parasites that infect millions of people and pigs worldwide, respectively. Reports of cross-infection and hybridization between the two species has stimulated molecular epidemiological studies ...

The Intestinal Roundworm Ascaris suum Releases Antimicrobial Factors Which Interfere With Bacterial Growth and Biofilm Formation

Frontiers in Cellular and Infection Microbiology, 2018
Ascariasis is a widespread soil-transmitted helminth infection caused by the intestinal roundworm Ascaris lumbricoides in humans, and the closely related Ascaris suum in pigs.

Helminths as architects of trained tolerance: implications for human health

Clinical &Translational Immunology, Volume 15, Issue 3, 2026.
Abstract Helminths infect nearly 2 billion people worldwide and are a major cause of chronic morbidity in low‐resource regions. Unlike bacterial and viral pathogens that elicit protective memory, helminths actively remodel host immunity to enable their years‐long persistence and reinfection.
