The present protocol describes a rodent model of newborn hypoxic-ischemic injury for identifying early changes in cerebral tissue by gross morphology and magnetic resonance imaging. This has benefits over existing models, which can be used to study late injury but do not allow the evaluation of reproducible early changes.
We describe the use of thin-layer chromatography direct bioautography assay and liquid chromatography-mass spectrometry to identify microbial natural products that display antagonism against fungal pathogens using the pathogen Sclerotinia sclerotiorum and biopesticidal Bacillus isolates as a model system.
