Surgical site infections in neonates and infants: is antibiotic prophylaxis needed for longer than 24 h?
In clean-contaminated and contaminated gastrointestinal operations, giving>24 h of postoperative antibiotics offered no protection against SSI. An adequately powered randomized clinical trial is needed to conclusively evaluate longer duration antibiotic prophylaxis.
OmpJ is a putative porin found in the outer membrane of the model metal reducer G. sulfurreducens that is required for respiration of extracellular electron acceptors such as soluble and insoluble metals. The effect of OmpJ in extracellular electron transfer is indirect, as OmpJ is required to keep the integrity of the periplasmic space necessary for proper folding and functioning of periplasmic and outer membrane electron transport components. The exclusive presence of ompJ in members of the Geobacteraceae family as well as its role in metal reduction suggest that the ompJ sequence may be useful in tracking the growth or activity of Geobacteraceae in sedimentary environments.
