Project description:To explore the circulating miRNA expression after subcutaneous injection of Gram negative and positive bacteria in the mice The recombinant specific Gram negative pathogens Escherichia coli (xen14) and Gram positive pathogens Staphyllococcus aureus (xen29) were purchased from the Caliper (Caliper, Princeton, NJ, USA). 1M-CM-^W108 Escherichia coli or Staphyllococcus aureus pathogen in 100 M-NM-<l PBS was injected subcutaneously with Fr. 25 needle into the back of the mice to cause bacterial infection of the mice. An extra group of animals was inoculated with PBS to serve as a negative control. The mice had access to food and water ad libitum both before and after bacteria injection. The mice were killed at the indicated time points (4, 8, and 24 h) after the bacteria injection, and whole blood was drawn.

Project description:N2 young adult animals were analyzed four hours after exposure to wild-type Candida albicans DAY185, heat-killed C. albicans DAY185 and heat-killed Escherichia coli OP50, all on Brain Heart Infusion (BHI) agar. It was necessary to use heat-killed E. coli OP50 as a control for these experiments because live E. coli OP50 (the normal nematode food source) is pathogenic to nematodes on BHI agar. These data identify the C. elegans genes that are differentially regulated during nematode infection with a human fungal pathogen.
