Diagnosis of Trypanosoma cruzi infection in Mexican populations: current conventional serology lacks adequate sensitivity and specificity. This subject is the theme of a new manuscript published in Memorias Journal.

A new Memorias Journal study explores the trypanosomicidal effect of butoconazole alone or with benznidazole against *T. cruzi*, highlighting the potential of drug repurposing and combination therapies for advancing Chagas disease treatment.

Researchers from UERJ analyzed the growth of endothelial cells (HUVECs) during S. agalactiae infection and the role of pilus PI-2b in endothelial barrier disruption and increased permeability. The results were published in the journal Memorias Journal.

Researchers from Brazil and Belgium studied the impact of oral probiotics (PB8 and Bifilac) in mice infected with Leishmania amazonensis. Among other findings, they discovered that prior use of probiotics significantly reduced macrophage infection by Leishmania by up to 27%.

Argentine researchers authored an article in MemoriasJournal presenting the results of a study that investigated the IgM and IgG antibody responses against specific lipid components of T cruzi, as well as against an enzyme it produces (TcPLA1).

Chagas disease, caused by Trypanosoma cruzi, remains a global health issue. To mark 50 years of research, the Brazilian Society of Protozoology held a four-day conference in Caxambu, Brazil. The discussions is disclousured in a manuscript published in Memorias Journal.

A study in Memorias Journal analyzed the ST gene in V. cholerae and V. mimicus, linked to cholera-like diarrhea. Researchers examined its prevalence, genomic context, and expression—filling key gaps in understanding ST toxin's role in vibrio pathogenesis.

The first report of a rare recombinant norovirus strain in Brazi is the subject of a paper published in Memorias Journal. Norovirus sequences from specimens from 5 people shared 100% of nucleotide identity, and had the highest similarity with a South Africa GII.10 strain detected

What is the impact of probiotics on T. cruzi infection in vitro and in mouse acute experimental models? A new manuscript published in Memorias Journal showed the potential of a combined therapeutic approach for Chagas Disease, using probiotics and benznidazole.

Given the role of microbiota in modulating host immunity, scientists explored whether probiotics could improve clinical outcomes against Leishmania amazonensis infection in a BALB/c mouse model for CL. To read de paper, visit memorias.ioc.fiocruz.br.
