Vertical transmission of Toxoplasma gondii in Australian marsupials

, 2009
To date, little is known about the dynamics of vertical transmission of Toxoplasma gondii in Australian marsupials. Studies in mice demonstrate that vertical transmission of T. gondii is common and that chronically infected mice can transmit T. gondii to

Toxoplasma gondii in rodents and shrews in Armenia, Transcaucasia

International Journal for Parasitology: Parasites and Wildlife
Toxoplasma gondii infections in small mammals are important because they serve as source of infection for the felids who excrete environmentally resistant oocysts in their feces. Here, the authors sought evidence for T.

From Infection to Anxiety: A Sequential Model Linking Latent Toxoplasmosis to Psychological Distress via Health and Stress

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT Identifying the drivers of chronic stress is crucial for understanding its impact on mental health. Latent toxoplasmosis, a widespread parasitic infection, has been linked to various psychological changes. The Stress‐Coping Hypothesis proposes that at least some of these changes are consequences of chronic stress arising from the infection's ...

Unusual MRI features in a case of presumed canine tick‐borne meningoencephalomyelitis

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract A 7‐year‐old, standard, wire‐haired dachshund presented with quickly progressive multifocal central nervous system signs, which localised to the brainstem and cervical myelopathy, including reduced cervical and thoracic limb muscle tone and withdrawal reflexes. Magnetic resonance imaging revealed bilateral, approximately symmetric, T2‐weighted

The Plasmodium berghei Ca(2+)/H(+) exchanger, PbCAX, is essential for tolerance to environmental Ca(2+) during sexual development.

, 2013
Ca(2+) contributes to a myriad of important cellular processes in all organisms, including the apicomplexans, Plasmodium and Toxoplasma. Due to its varied and essential roles, free Ca(2+) is tightly regulated by complex mechanisms.

RNF213 Is an Interferon‐Stimulated Gene That Targets Influenza A Virus NP and Activates MDA5 to Restrict Infection

Advanced Science, Volume 13, Issue 31, 4 June 2026.
RNF213 is characterized as a dual‐functional antiviral effector. It directly mediates the degradation of the influenza A virus nucleoprotein (NP) while simultaneously activating the MDA5‐mediated innate immune signaling pathway. This coordinated response establishes a powerful host defense system against viral infection. ABSTRACT Influenza A virus (IAV)

Prevalence of Toxoplasma gondii IgG Antibodies and Associated Risk Factors in Psychiatric Patients from Western Romania: A Cross-Sectional Study

Microorganisms
Infection with the coccidian parasite Toxoplasma gondii was associated with an increased risk of several mental disorders. We conducted a case–control study of 464 consecutive psychiatric patients and assessed the prevalence of IgG antibodies against T ...

Fecal Microbiota Transplantation From Patients With Social Anxiety Disorder Is Associated With General Anxiety‐Like Behavior and Gut Microbiota Alterations in Mice

Brain and Behavior, Volume 16, Issue 6, June 2026.
Fecal microbiota transplantation from patients with social anxiety disorder (SAD) into mice induces anxiety‐like behaviors, accompanied by gut microbiota alterations (increased Bacteroidota, decreased butyrate producers), downregulation of microbial metabolic pathways, and reduced plasma tryptophan, suggesting a causal role of gut dysbiosis in SAD ...

Hemoglobin Digestion Genes Are Conserved in Lizard‐Infective Plasmodium Species With Different Host Cellular Niches

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Despite their evolutionary relatedness to malaria parasites that infect humans, wildlife Plasmodium—particularly those that infect birds and lizards—are understudied, leaving their vast genetic diversity to be explored. By assembling parasite transcriptomes from Plasmodium‐infected lizard blood, we provide the first evidence that lizard‐infective ...
