The identification of host genes associated with resistance to Phytophthora capsici is crucial to developing strategies of control against this oomycete pathogen. Since there are few sources of resistance to P. capsici in crop plants, non-host plants represent a promising source of resistance genes as well as excellent models to study P. capsici - plant interactions. We have previously shown th...

Various safety-critical devices, such as industrial control systems, medical devices, and home automation systems, are configured through web interfaces from remote hosts that are standard PCs. The communication link from the host to the safety-critical device is typically easy to protect, but if the host gets compromised, the adversary can manipulate any user-provided configuration settings wi...

Infections remain the most common immediate causes of morbidity in immune compromised hosts. The abated host defences are responsible for an increased susceptibility to various uncommon and opportunistic pathogens, and to a lowered host inflammatory response. Skin lesions develop in up to a third of infections in these patients, and they possibly represent the initial step of a systemic illness...

The extent to which pathogens maintain the extraordinary polymorphism at vertebrate Major Histocompatibility Complex (MHC) genes via balancing selection has intrigued evolutionary biologists for over half a century, but direct tests remain challenging. Here we examine whether a well-characterized epidemic of Mycoplasmal conjunctivitis resulted in balancing selection on class II MHC in a wild so...

Address harvesting is the act of searching a compromised host for the names and addresses of other targets to attack, such as occurs when an email virus locates target addresses from users’ address lists or mail archives. We examine how host addresses harvested from Secure Shell (SSH) clients’ known hosts files can aid those attacking SSH servers. Each user’s known hosts file contains the names...

The presence of compromised hosts in any network degrades the performance in many ways. The compromised nodes form the botnet and the detection of them is most primary solution to improve the network performance. The problem of botnet detection has been approached in many ways using fl ow factors but does not produce a remarking solution. To improve the botnet detection effi ciency, a novel sta...

Rhizoctonia solani is a necrotrophic fungal pathogen that causes disease in diverse plant species. In recent years, the genomic and transcriptomic studies have identified several candidate pathogenicity determinants of R. solani; however, most them remain to be validated. this study, we report viral vector-based host-induced gene silencing (HIGS) as well dsRNA (double-stranded RNA)-based approa...
