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

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 ...

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 ...

Evaluation of the Cutaneous Immunological Milieu Before and After Treatment With Meglumine Antimoniate in Dogs Naturally Affected by Leishmaniosis due to Leishmania infantum

Veterinary Dermatology, EarlyView.
Background: Canine leishmaniosis (CanL) is a zoonotic disease of variable severity. The typical immune response is driven by an exaggerated humoral immune response. Protective immunity is mediated by pro‐inflammatory cytokines that enhance macrophage leishmanicidal activity. Objective: To evaluate the cutaneous and the systemic immune responses as well

Successful in vitro propagation of feline coronavirus from clinically diagnosed feline infectious peritonitis cases using Vero cells: A potential model for future research

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Feline coronavirus (FCoV) causes inapparent to progressive fatal feline infectious peritonitis (FIP) in domestic and wild cats, which affects multiple‐organ systems. Methods We investigated three clinically sick cats using different laboratory and molecular tests to diagnose and confirm FCoV and propagate the virus in Vero cell ...

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.

The role of T cells in sepsis of distinct infectious aetiologies

Clinical and Translational Discovery, Volume 6, Issue 2, April 2026.
Pathogen‐specific sepsis induces mitochondrial dysfunction in T cells, leading to functional alterations. Single‐cell transcriptomics reveals subtype‐specific impairments involving reactive oxygen species accumulation, mtDNA damage, calcium dysregulation, and metabolic reprogramming.

Anticorpos anti-Neospora caninum em bovinos de leite do sudoeste do estado do Paraná

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Since November 2007 until May 2009, 1,778 serum samples of cattle from dairy herds of the Southwest of Paraná State, Brazil, were used for search of anti-Neospora caninum antibodies. The frequency of seropositive animals, assessed by IFAT, was 24.2% (431/

Leishmania Extracellular Vesicles as a Preventive Vaccine Platform Against Leishmaniasis

Journal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
The potential of Leishmania‐derived extracellular vesicles (EVs) as a vaccine platform was investigated, emphasizing an affordable, GMP‐compliant production and purification method. Immunization with EV vaccines, either unadjuvanted or combined with α‐galactosylceramide (αGC), induced robust humoral and cellular immune responses, conferring protection ...

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.
