Biogenesis and trafficking of membrane vesicles are essential and well-studied processes in eukaryotes. In contrast, vesiculation in bacteria is not well understood. Outer membrane vesicles (OMVs) are produced in Gram-negative bacteria by blebbing of the outer membrane. In addition to the roles in pathogenesis, cell-to-cell communication and stress response, recent work has suggested that OMVs ...
This work presents the design, fabrication, and testing of a cross-flow filtration microdevice, for the continuous extraction of bacteria from a whole blood sample for the treatment of sepsis and bacteremia. The system consists of a two-compartment microdevice with two aligned sets of PDMS microchannels, separated by a porous polycarbonate (PCTE) membrane with 2 m pores. When a whole blood sam...
Intestinal bacteria were classified as gram-positive or gram-negative by an electrode system with a basal plane pyrolytic graphite electrode and a porous nitrocellulose membrane filter to trap bacteria. When the potential of the graphite electrode was run in the range of 0 to 1.0 V versus the saturated calomel electrode (SCE), gram-positive bacteria gave peak currents at 0.65 to 0.69 V versus t...
Exposure of E. coli K12 W1485 to the cytolytic alternative pathway assembled from the 11 isolated pathway proteins resulted in killing of the bacteria, as evidenced by loss of viability. Lysis of the bacteria required introduction of lysozyme into the reaction mixture. The time-course and dose dependency of bacteriolysis in the isolated system were identical to those in C4-depleted serum. The b...
