Despite very numerous studies on Alzheimer's disease (AD), especially on amyloid plaques and neurofibrillary tangles, little information has been obtained thus on the causes of the disease. Evidence is described here that implicates firstly herpes simplex virus type 1 (HSV1) as a strong risk ...
Is a pathogen an antigen? A pathogen is not an antigen, but pathogens contain antigens. A pathogen is an organism that causes disease. An antigen is part of a pathogen that activates the immune system and causes an immune response.What...
EFFICIENT early diagnosis and treatment of sexua-lly transmitted genital ulcer disease (GUD) arebecoming increasingly important because of thecorrelation between GUD and human immunodeficiencyvirus transmission.1-3 Studies suggested that the commonetiolo关键词: multiplex polymerase chain reaction genital ulce...
It's convenient to think that bloodborne pathogens spread only through blood, and that they only cause one disease. But this lesson will teach you...
(E) plant species. The role of factors is very interesting that they lead to the occurrence of the plant disease epidemic in the fields. It might the three relationships that happened among the strains of plant pathogens, (A) Competition, (B) Cooperation, (C) Coexistence (Abdullah et al....
Esca is a grapevine wood disease that seriously affects vine yield and longevity. Our knowledge of this disease and its causes has changed profoundly in recent years, as it has become clear that esca in fact comprises a number of distinc... G Surico,L Mugnai,G Marchi - Springer Netherlands...
Plant disease occurs only when pathogenic microorganisms encounter susceptible plants under favourable environmental conditions. Microbe-associated molecular patterns (MAMPs). Structurally conserved microorganism-derived signature molecules, including peptides, carbohydrates or fatty acids, that are detected by ...
We find that the accumulation of specialist pathogens in monocultures decreases host plant yields and that pathogen dilution predicts plant productivity gains derived from diversity. Pathogen specialization predicts the strength of the negative feedback between plant species in greenhouse assays. These ...

The diagenetic processes that make ancient DNA research generally difficult are also impediments to ancient pathogen research and perhaps more so given that their DNA may represent an even rarer proportion of the remaining nucleic acids in a fossil sample than host DNA. However, studies performed ...
