This study proposed the use of satellite hyperspectral imagery to support tick-borne infectious diseases surveillance based on monitoring the variation in amplifier hosts food sources. To verify this strategy, we used the data of the human rickettsiosis occurrences in southeastern Brazil, region in which the emergence of this disease is associated with the rising capybara population. Spatio-tem...

There is clearly a significant increase in awareness of the risks from food-borne diseases among consumers in western countries in the past decade. The concern about the quality and safety of food appears to be driven by increased affluence, new scientific discoveries, by more sophisticated measurements and analyses, by new information about linkages between diet and health, by new food technol...

Staphylococcal enterotoxins are major causing agents of food-borne diseases. Their detection in food remnants for risk assessment or food poisoning outbreaks investigation suffers from a lack in comprehensive immunological tools. In this study, we demonstrate that the combination of immunocapture and Protein Standard Absolute Quantification (PSAQ) strategy, which uses isotope-labeled enterotoxi...

food-borne botulism is one of the dangerous food poisonings in human in the world. the specimens of 115 patients (serum and stool) with clinical symptoms of botulism, who were inpatient and outpatient were collected at some medical centers in tehran and other areas of iran, between april 1984 to august 1994. in this survey, specimens of 73 patients showed the toxin and spore of c.botulinum. clo...

The outbreak of enterohaemorrhagic Escherichia coli in Germany last year and recent reports about the emergence of Salmonella Kentucky as a “new superbug” have re-focused public attention on food-borne diseases. Salmonellosis is an important cause of food-borne disease with significant economic burden to the population and healthcare systems. In the last century, microbiologists have identified...

Background: Every institution which provides food for a large group of consumers has the responsibility to keep the safety and wholesomeness of food otherwise it may result outbreaks of food borne illness. The most identified contributing factors of food borne illness in mass catering establishments were cross contamination, dirty work environment and poor personal hygiene practice by food hand...

We report on a novel technique for sorting and identification of single biological cells and food-borne bacteria based on laser tweezers and Raman spectroscopy (LTRS). With this technique, biological cells of different physiological states in a sample chamber were identified by their Raman spectral signatures and then they were selectively manipulated into a clean collection chamber with optica...
