AI Article Synopsis

  • The text discusses a Gram-negative bacterium responsible for Q fever, a zoonotic disease that affects various hosts, including humans and animals.
  • It highlights the challenges of studying the bacterium's virulence in costly and ethically constrained mammalian models.
  • The study presents an alternative approach using a specific larval model to investigate the virulence of strains isolated from domesticated ruminants.

Article Abstract

is a small Gram-negative intracellular bacterium and is the causative agent of Q fever, which is a zoonotic disease with a worldwide distribution. Domesticated ruminants are the main reservoir of the disease, but the bacterium is able to infect a wide range of hosts, including humans, arthropods and invertebrates. Virulence studies of strains usually require a suitable animal model. However, mammalian models are costly and are associated with many ethical constraints. An alternative infection model using has been used to study the virulence of several bacterial as well as fungal pathogens. Moreover, the larvae model has been used to identify virulence genes using phase II strain Nine Mile mutants. In our study we describe its use for the characterization of strains isolated from ruminants.

Aflatoxin contamination of corn can occur when developing kernels are infected by the plant pathogen Aspergillus flavus. One route of infection is from airborne conidia. We executed a series of experiments within the corn canopy during two growing seasons and in two states to document the abundance and dynamics of the airborne A.

This study reports draft genomes of 30 bacteria representative of the plant food system microbiota and isolated from different sources in Italy and France. Individual genomes were reconstructed using PacBIO DNA sequencing: taxonomic classification and distribution of genes involved in microbe-environment interactions are reported to facilitate strains' characterization and utilization.

The marine ecosystem is characterized by a rich diversity of bacterial hosts and their phages. The propagation of phages is primarily limited by their ability to adsorb to host cells and is further challenged by various bacterial defense mechanisms. To fully realize the potential of phage therapy in aquaculture, a comprehensive understanding of phage-host interactions and their regulation is essential.

Immunocompetent host immune responses, such as formation of pulmonary granulomas, control the infection and prevent disseminated disease.

is a bacterium associated with colorectal cancer (CRC) tumorigenesis, progression, and metastasis. Fap2 is a fusobacteria-specific outer membrane galactose-binding lectin that mediates adherence to and invasion of CRC tumors. Advances in omics analyses provide an opportunity to profile and identify microbial genomic features that correlate with the cancer-associated bacterial virulence factor Fap2.
