Salmonella grows massively and aerobically in fecal matter

Show abstract
The use of wastewater for irrigation and animal manure as fertilizer can cause transmission of intestinal pathogens, conditions frequently observed in Low- and Middle-Income Countries (LMICs). Here we tested the ability of Salmonella to grow in the fecal matter; we inoculated freshly isolated Salmonella strains (from chickens) in chicken fecal matter and incubated for 24, 48 and 72 hrs under aerobic and anaerobic conditions. We found that both Salmonella and E. coli multiplied massively in fecal matter outside a host for 72 hrs, being their growth higher in aerobic conditions. Our results have critical implications in waste management, as we demonstrate that aerobic treatments may not be the best to reduce the number of Salmonella in the environment.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
