Enteropathogenic Escherichia coli O157 Strains from Brazil

Emerging Infectious Diseases, 2003
We describe two serogroup O157 Escherichia coli strains from Brazilian infants with diarrhea. A variety of assays indicate that these strains belong to the enteropathogenic, not the enterohemorrhagic, pathotype.

Highly conserved type 1 pili promote enterotoxigenic E. coli pathogen-host interactions [PDF]

, 2017
Enterotoxigenic Escherichia coli (ETEC), defined by their elaboration of heat-labile (LT) and/or heat-stable (ST) enterotoxins, are a common cause of diarrheal illness in developing countries.

Detecting TP53 mutations in paired liquid and tissue biopsies from patients with high‐grade serous ovarian carcinoma

International Journal of Cancer, Volume 158, Issue 8, Page 2043-2050, 15 April 2026.
What's New? High‐grade serous ovarian carcinoma is often diagnosed at advanced stages due to non‐specific symptoms and the lack of reliable screening methods. This proof‐of‐concept study introduces a novel TP53 mutation panel using unique molecular identifier‐based next‐generation sequencing for sensitive detection of high‐grade serous ovarian ...

Chaperone-usher fimbriae in a diverse selection of Gallibacterium genomes

BMC Genomics, 2014
Fimbriae are bacterial cell surface organelles involved in the pathogenesis of many bacterial species, including Gallibacterium anatis, in which a F17-like fimbriae of the chaperone-usher (CU) family was recently shown to be an important virulence factor

A Longitudinal Study of Children's Hippocampal Development: Investigating Maternal Physical Activity, Depression, and Education

Developmental Neurobiology, Volume 86, Issue 2, April 2026.
ABSTRACT The developing hippocampus is particularly sensitive to early environmental influences, including during pregnancy. This longitudinal neuroimaging study examined associations between prenatal maternal physical activity and depression, maternal education, and hippocampal development from early childhood to early adolescence.

Development of monoclonal antibodies against P. gingivalis Mfa1 and their protective capacity in an experimental periodontitis model

mSphere
Porphyromonas gingivalis (P. gingivalis), a gram-negative, black-pigmented anaerobe, is a major etiological agent and a leading cause of periodontitis. Fimbriae protein Mfa1 is a key virulence factor of P. gingivalis and plays a crucial role in bacterial

Fimbriae reprogram host gene expression – Divergent effects of P and type 1 fimbriae

PLOS Pathogens, 2019
Pathogens rely on a complex virulence gene repertoire to successfully attack their hosts. We were therefore surprised to find that a single fimbrial gene reconstitution can return the virulence-attenuated commensal strain Escherichia coli 83972 to virulence, defined by a disease phenotype in human hosts. E.

MrkH, a Novel c-di-GMP-Dependent Transcriptional Activator, Controls Klebsiella pneumoniae Biofilm Formation by Regulating Type 3 Fimbriae Expression

PLoS Pathogens, 2011
Klebsiella pneumoniae causes significant morbidity and mortality worldwide, particularly amongst hospitalized individuals. The principle mechanism for pathogenesis in hospital environments involves the formation of biofilms, primarily on implanted ...

Bactericidal, Bacteriostatic, and Fungicidal Activities of Clausena anisata Fruit and Its Compounds, Stigmasteryl 3‐Palmitate (a Phytosterol Ester) and Phellopterin (a Furanocoumarin), Against Some Clinical Pathogens

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
C. anisata fruit extract and its compounds demonstrated potent broad‐spectrum antimicrobial activity, notably against Klebsiella pneumoniae (MIC 0.625 mg/mL; MLC 2.5 mg/mL) and Candida albicans (MIC 0.0781 mg/mL; MLC 0.625 mg/mL). The findings highlight promising bactericidal and fungicidal potential of stigmasteryl 3‐palmitate and phellopterin against
