Detection of Viable But Non-Culturable State of Escherichia coli O157:H7 Using Reverse Transcription PCR

Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods:  Escherichia. coli O157:H7 was inoculated i...

Regulation of Francisella Tularensis Virulence

Francisella tularensis is one of the most virulent bacteria known and a Centers for Disease Control and Prevention Category A select agent. It is able to infect a variety of animals and insects and can persist in the environment, thus Francisella spp. must be able to survive in diverse environmental niches. However, F. tularensis has a surprising dearth of sensory and regulatory factors. Recent...

Nutritional virulence of Francisella tularensis

One of the most fundamental aspects of infectious diseases is microbial acquisition of nutrients in vivo, which impacts virulence and antibiotic treatment. Therefore, it is not surprising that part of the innate host defense against microbial infection is to limit access of various invading pathogens to sources of host nutrients (Abu Kwaik and Bumann, 2013; Eisenreich et al., 2013). Despite thi...

Growth conditions and environmental factors impact aerosolization but not virulence of Francisella tularensis infection in mice

In refining methodology to develop a mouse model for inhalation of Francisella tularensis, it was noted that both relative humidity and growth media impacted the aerosol concentration of the live vaccine strain (LVS) of F. tularensis. A relative humidity of less than 55% had a negative impact on the spray factor, the ratio between the concentration of LVS in the aerosol and the nebulizer. The s...
