Two hуperspectral remote sensing techniques, spectral reflectance and chlorophyll fluorescence, were used for the identification of biotic stress (sharka disease) in plum trees at an early stage without visible symptoms on the leaves. The research was focused on cultivars that are widely spread in Bulgaria: ‘Angelina’, ‘Black Diamond’ and ‘Mirabelle’. Hyperspectral reflectance and fluorescence ...

in an attempt to convert mass vaccination practices to the extended programme on immunization, a sero-evaluation study was carried out in rural iran in 1976. a total of 22 246 rural children of 2-12 years of age were sampled. blood samples taken on filter paper were tested by indirect hemagglutination technique to determine the level of circulating antibodies against tetanus toxoid. tetanus was...

background: brucellosis is a zoonotic disease and its symptoms and appearances are not exclusive in human and its tradi­tional diagnosis is based on blood culture and serological methods. for more sensitive and specific detection, the pcr method is recommended. methods: one hundred four blood samples were gathered from suspicious patients with brucellosis different ages form ker­manshah, mazand...

conclusions findings of this study demonstrate no significant difference between levels of h. pylori specific antibodies of iga, igg, anti-caga and the presence of pcos disorders, and also indicate that serologic testing is a sensitive method for the detection of h. pylori antibodies. the high prevalence of h. pylori positive antibody levels in both pcos and non-pcos patients can be probably as...

helicobacter pylori (h.pylori) is the most common human infection in the world. this agent has a strong role in pathogenesis of chronic gastritis and peptic ulcers. therefore introducing of simple and cost effective and non invasive tests are important for diagnosis of h.pylori infections. in this study 215 patient suffering from different gastrointestinal disorders referred to gi endoscopy dep...

No association was found between inflammatory bowel disease and infection with C. trachomatis or C. psittaci when patients were tested for the presence of these organisms using immunohistological, cell culture isolation, and serological techniques.

Plant diseases caused by viruses are the most menace to sustainable agriculture, leading numerous billion dollars in losses annually. Proper and accurate detection of plant is always key developing appropriate solutions manage economic them. Advances technology have simplified tools available detect diagnose at a time when control measures should be used. Currently, nucleic acid serological bas...
