Determining if a nonhealing wound is infected can be difficult. The surface of a wound is not sterile and can be colonized with numerous commensal, environmental, and potentially pathogenic microorganisms. Different types of wounds have various clinical presentations, with some signs and symptoms more likely to be present than others depending on the type and location of the wound. Clinicians o...

Laboratory cultures of heterotrophic protists are often xenic, meaning that the culture contains more than one microbial organism. In this study, we analyzed genome-assembly data from four marine protist flagellates—the malawimonad Imasa heleensis, undescribed mantamonad strain SRT-306, discobid Ophirina amphinema, and cryptist Palpitomonas bilix—specifically to search for genomes cocultured ba...

  Abstract   Background: Wound infection is a frequent and severe complication in burn patients   accounting for a high number of mortalities. There are some reports comparing   swab and biopsy cultures of wounds of various etiologies or chronic wounds.   Objectives: The aim of the study was to evaluate burn wound infection by different   bacteriologic methods of surface swab and tissue biopsy ...

The transient behavior of a continuous culture of Klebsiella pneumoniae with mixed feed of glucose and xylose arising from step-up and step-down in dilution rates and from a feed-switching experiment is presented. he organism gradually switches from simultaneous utilization of the substrates at low growth rates to preferred utilization of the faster substrate (i.e, supporting a higher growth ra...

Aerobic cultures of Staphylococcus simulans biovar staphylolyticus characteristically achieved about 17 times higher bacterial densities and produced about 7 times higher concentrations of exoprotein than did anaerobic cultures. However, total exoprotein secreted per unit of bacterial dry weight typically was 2.3 times greater for anaerobic cultures. As determined by SDS-PAGE, anaerobic culture...
