Different edible portions including meat (lump, claw and backfin) and roe of blue swimming crab () were analyzed. Both meat and roe had high protein content, but a greater fat content was found in roe. All meats showed higher levels of polyunsaturated fatty acids than roe.

Unlabelled: Bacteria have evolved diverse strategies to ensure survival under nutrient-limited conditions, where rapid energy generation is not achievable. Here, we performed a transposon insertion site sequencing loss-of-function screen to identify genes that promote pathogen fitness in stationary phase. We discovered that the aintenance of ipid symmetry (Mla) pathway, which is crucial for transferring phospholipids from the outer to the inner membrane, is critical for stationary phase fitness.

Japan has experienced several large earthquakes in the past 30 years. Emergency evacuation shelters become overcrowded immediately after disasters. Deteriorating sanitary conditions in toilets are associated with a higher risk of infectious pathogen transmission.

Competition between bacterial species is a major factor shaping microbial communities. It is possible but remains largely unexplored that competition between bacterial pathogens can be mediated through antagonistic effects of bacterial effector proteins on host systems, particularly the actin cytoskeleton. Using Typhimurium invasion into cells as a model, we demonstrate that invasion is inhibited if the host actin cytoskeleton is disturbed by actin-specific toxins, namely, MARTX actin crosslinking (ACD) and Rho GTPase inactivation (RID) domains, TccC3, and 's own SpvB.
