Adhesins mediate the introduction of bacteria to the host in the sometimes life-long relationship of uropathogenic Esherichia coli (UPEC) and the human urinary tract. As a class of extracellular proteins, adhesins enable bacteria to adhere to and, in some cases, invade host tissue; adhesins render UPEC virulent and permit host colonization. Adhesin receptor interactions at the host interface de...
Streptococcus pyogenes is an important pathogen that causes a variety of diseases. The most common infections involve the throat (pharyngitis) or skin (impetigo); however, the factors that determine tissue tropism and severity are incompletely understood. The S. pyogenes NAD(+) glycohydrolase (SPN) is a virulence factor that has been implicated in contributing to the pathogenesis of severe infe...
Adenoviruses (Ad) have a long history as DNA-transfer vehicles in various medical applications including vivo gene therapy [1]. In this context, the favorable safety profile of Ad has been considered major benefit, since lack integration into host cell genome eliminates potential risks associated with insertional mutagenesis. This is combined comparatively high packaging capacity for foreign DN...
Virotherapy of cancer using oncolytic adenoviruses has shown promise in both preclinical and clinical settings. One important challenge to reach the full therapeutic potential of oncolytic adenoviruses is accomplishing efficient infection of cancer cells and avoiding uptake by normal tissue through tropism modification. Towards this goal, we constructed and characterized an oncolytic adenovirus...
Animal papillomaviruses are widely used as models to study papillomavirus infection in humans despite differences in genome organization and tissue tropism. Here, we have investigated the extent to which animal models of papillomavirus infection resemble human disease by comparing the life cycles of 10 different papillomavirus types. Three phases in the life cycles of all viruses were apparent ...
Wolbachia are intracellular bacteria that infect invertebrates at pandemic levels, including insect vectors of devastating infectious diseases. Although Wolbachia are providing novel strategies for the control of several human pathogens, the processes underlying Wolbachia's successful propagation within and across species remain elusive. Wolbachia are mainly vertically transmitted; however, the...
