Strategies to eradicate the vector-borne infectious diseases (e.g. malaria and Japanese encephalitis) are often directed at controlling vectors with insecticides. Spraying insecticide, however, opens the way for the development of insecticide resistance in vectors, which may lead to the failure of disease control. In this paper, we examine whether the combined use of insecticide spray and zoopr...

abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...

This review illuminates key findings in our understanding of grapevine xylem resistance to fungal vascular wilt diseases. Grapevine (Vitis spp.) vascular diseases such as esca, botryosphaeria dieback, and eutypa dieback, are caused by a set of taxonomically unrelated ascomycete fungi. Fungal colonization of the vascular system leads to a decline of the plant host because of a loss of the xylem ...

Disease susceptibility is linked to nutritional status for a wide range of human and animal diseases. Nutritional status can influence both resistance (ability to resist the pathogen) and resilience (ability to tolerate or ameliorate the effects of the pathogen). This review focuses on the nutritional modulation of gastro-intestinal nematode infection in domestic ruminants, primarily sheep. It ...

Natural resistance against brucellosis was reviewed from historical and biological perspectives with regard to animals, humans and Brucella spp. Unfortunately, brucellosis continues to be a serious worldwide bacterial zoonosis of major significance to animal and human populations. Host genetic, innate and adaptive immune factors significantly influence the outcome of brucellosis as does the ena...

Potato virus Y (PVY) and Potato mop-top virus (PMTV) are viruses whose geographical distribution is expanding and economic losses are increasing, in contrast to most of other viruses infecting potato crops. Most potato cultivars lack broad-spectrum resistance to the new, genetically complex strains of PVY, and no efficient resistance to PMTV is known in potato. Control of the vectors of these v...

Antibiotic therapy has been of unquestionable value in terms of saving lives and reducing suffering caused by infectious diseases. However, the widespread and indiscriminant use of antibiotics has not been without significant consequences. Some of these consequences include increased antibiotic resistance in pathogenic strains of bacteria. In addition, the indiscriminate use of antibiotics has ...

Host organisms can respond to the threat of disease either through resistance defenses (which inhibit or limit infection) or through tolerance strategies (which do not limit infection, but reduce or offset its fitness consequences). Here we show that resistance and tolerance can have fundamentally different evolutionary outcomes, even when they have equivalent short-term benefit for the host. A...
