Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Seroprevalence, spatial analysis and risk factors of infection with Neospora caninum in cattle in Brazil’s northern Pantanal wetland

Revista Brasileira de Parasitologia Veterinária, 2018
Neosporosis is caused by an obligate intracellular protozoan, Neospora caninum . It is considered one of the most widespread and frequent causes of abortion in cattle worldwide. To evaluate the prevalence of anti-N. caninum antibodies and associated risk

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Computed tomographic diagnosis and treatment of pneumolabyrinth in a mare with temporohyoid osteoarthropathy

Equine Veterinary Education, EarlyView.
Summary Pneumolabyrinth, which is the presence of gas within the labyrinth of the inner ear, can be associated with severe peripheral vestibular signs. This report describes a case of pneumolabyrinth in a horse that presented with vestibular ataxia. An 8‐year‐old Quarter Horse mare that presented with cranial nerve VII deficits underwent a standing ...

Sex ratios in the rodent malaria parasite, Plasmodium chabaudi [PDF]

, 2003
The sex ratios of malaria and related Apicomplexan parasites play a major role in transmission success. Here, we address 2 fundamental issues in the sex ratios of the rodent malaria parasite, Plasmodium chabaudi.

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 ...

Seroprevalence rates of antibodies againstLeishmania infantum and other protozoan and rickettsial parasites in dogs

, 2013
Canine visceral leishmaniasis (CVL) is caused by the protozoan Leishmania infantum, which infects dogs and humans in many regions of Brazil. The present study involved an indirect fluorescent antibody test (IFAT) to analyze L.

Trans-sialidase delivered as a naked DNA vaccine elicits an immunological response similar to a Trypanosoma cruzi infection

Brazilian Journal of Medical and Biological Research, 1999
Trypanosoma cruzi, the protozoan parasite that causes Chagas' disease, does not synthesize sialic acid, but expresses a trans-sialidase (TS) that catalyzes the transfer of sialic acid from host glycoconjugates to the parasite surface.

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

Immunization with Leishmania tarentolae-derived norovirus virus-like particles elicits high humoral response and stimulates the production of neutralizing antibodies

Microbial Cell Factories, 2021
Background Noroviruses are a major cause of epidemic and sporadic acute non-bacterial gastroenteritis worldwide. Unfortunately, the development of an effective norovirus vaccine has proven difficult and no prophylactic vaccine is currently available ...
