We report on the first isolation of an extended-spectrum beta-lactamase-producing Leclercia adecarboxylata strain from the bloodstream in a 58-year-old man with acute myeloid leukemia. The strain, resistant to ceftazidime, cefotaxime, and aztreonam, produces the SHV-12 beta-lactamase, one of the most common variants found in Italian nosocomial isolates of Enterobacteriaceae.

Plant growth-promoting rhizobacteria (PGPR) and biochar (BC) are recognized as effective biological agents for enhancing stress tolerance and mitigating heavy metal toxicity in crops. Therefore, this study aims to investigate the effects of the cadmium (Cd)-resistant PGPR strain Leclercia adecarboxylata HW04 (>4 mM Cd resistance) on soybean plants exposed to 300 μM Cd. HW04 was observed to possess the innate ability to synthesize indole-3-acetic acid and exopolysaccharides, which facilitated the absorption of Cd in the medium.

This study aims to explore the pathogenic potential of as a rare pathogen in immunocompetent individuals and to analyze how mental health status may influence susceptibility to infection. We report a case of bacteremia in a 31-year-old immunocompetent female who developed infection during an episode of severe depression. Although the patient exhibited self-harm tendencies, a thorough physical examination did not reveal any external wounds or signs of injury.

Maize ( L.), a key staple crop in Sub-Saharan Africa, is particularly vulnerable to concurrent drought and heat stress, which threatens crop yield and food security. Plant growth-promoting rhizobacteria (PGPR) have shown potential as biofertilizers to enhance plant resilience under such abiotic stresses.

Article Synopsis
  • Oral microbial communities can move from the mouth to the gut, potentially contributing to cancers like colorectal cancer (CRC) and inflammatory bowel disease (IBD).
  • Researchers identified over 55,000 genes related to this translocation, focusing on those involved in signaling and cell structure, which are similar in both CRC and IBD.
  • A newly identified pathogen has been found in higher amounts in CRC patients, with its genes playing a role in various metabolic processes, highlighting the genetic evidence of how oral pathogens can influence gastrointestinal cancer development.

Article Synopsis
  • - Colistin is a last-resort antibiotic for multidrug-resistant bacteria, but the mcr-1 gene, which causes colistin resistance, is spreading and poses a public health risk.
  • - Researchers found a strain of Leclercia adecarboxylata carrying the mcr-1 gene in Seoul's wastewater, showing resistance to colistin and multiple other antibiotics.
  • - The study highlights the importance of monitoring antimicrobial resistance in wastewater, as they discovered a plasmid (pCOL134-1) that aids in the gene's transfer between bacteria.
