We present the case of a 3-month-old immunocompromised infant who developed a vascular catheter-related bloodstream infection caused by Pantoea septica. Susceptibility testing results for this isolate and 10 additional clinical strains are provided to help define the susceptibility profile of this infrequently recovered organism.

View Article and Find Full Text PDFTropical rainforests in Sri Lanka are biodiversity hotspots, which are sensitive to anthropogenic disturbance and long-term climate change. We assessed the diversity, endemism and conservation status of these rainforests across a wide altitudinal range (100-2200 m above sea level) via a complete census of all trees having ≥ 10 cm diameter at breast height in ten one-hectare permanent sampling plots. The numbers of tree families, genera and species and community-scale tree diversity decreased with increasing altitude.

- Foliar diseases caused by specific fungi significantly hinder Welsh onion production in Taiwan, prompting interest in eco-friendly biocontrol methods using endophytes instead of chemical fungicides.
- The study isolated 109 bacterial and 31 fungal strains from healthy Welsh onion leaves and identified several with strong antagonistic potential against major leaf blight pathogens, particularly highlighting the bacterial strain GFB08 as the most effective.
- Strain GFB08 demonstrated high disease control through its antimicrobial properties and secretion of cell wall degrading enzymes, suggesting its potential as a biological control agent against Welsh onion leaf blight.
Introduction: Variations in the human ocular volumes are related to ocular pathologies including congenital glaucoma, microphthalmus, buphthalmus, and macrophthalmus. As the currently published reference ocular volumes are prone to physiological and racial variations, population specific values may provide more precision in ophthalmological interventions. This study was conducted to assess the age and sex dependent differences in ocular volumes in Sri Lankan individuals using magnetic resonance imaging (MRI).
