Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU) in humans. In contrast to uropathogenic E. coli (UPEC) that cause symptomatic urinary tract infection, very little is known about the mechanisms by which these strains colonize the urinary tract. Here, we have investigated the biofilm-forming capacity on abiotic surfaces of groups of ABU strains and UPEC...

Microbial acquisition of nutrients in vivo is a fundamental aspect of infectious diseases, and is a potential target for antimicrobial therapy. Part of the innate host defense against microbial infection is nutritional restriction of access to sources of host nutrients (Abu Kwaik and Bumann, 2013; Eisenreich et al., 2013). Despite this host nutritional restriction, there has been a long held pr...

In this note we prove, by using straightforward arguments, a stronger version of a well-known capacity result proved by Abu-Mostafa and St. Jacques. Our results states that no Hoppeld memory can have a \capacity" (in Abu-Mostafa and St. Jacques's sense) exceeding 1, thereby showing the inadequacy of their capacity notion.

Many of the plant species found that it can be used medically (Ali-Shtayeh and Abu, 1999). Essential oils are aromatic substances which are obtained from various plant parts by steam distillation; many of which exhibit antibacterial (Ozcan et al., 2006), antifungal (Chee and Lee, 2007) and antiviral (Khan et al., 2005) activity. Lemongrass (Cymbopogon citratus) is widely used in traditional med...
