Improved monitoring tools are important for the control of Campylobacter bacteria in broiler production. In this study, we compare the sensitivities of detection of Campylobacter by PCR with feces, dust, and air samples during the lifetimes of broilers in two poultry houses and conclude that the sensitivity of detection of Campylobacter in air is comparable to that in other sample materials. Profiling of airborne particles in six poultry houses revealed that the aerodynamic conditions were dependent on the age of the chickens and very comparable among different poultry houses, with low proportions of particles in the 0.5- to 2-microm-diameter range and high proportions in the 2- to 5-microm-diameter range. Campylobacter could also be detected by PCR in air samples collected at the hanging stage during the slaughter process but not at the other stages tested at the slaughterhouse. The exploitation of airborne dust in poultry houses as a sample material for the detection of Campylobacter and other pathogens provides an intriguing possibility, in conjunction with new detection technologies, for allowing continuous or semicontinuous monitoring of colonization status.

The present invention relates to a method, a chip, a device and a system for extraction of biological material form biological cells. The invention involves exposing the biological particles to an alternating electric field in a sample chamber and may also involve subsequent analysis of the biological material after the extraction.

Method, Chip, Device and System for Extraction of Biological Materials

The present invention relates to a method, a chip, a device, and a system for detection of biological particles. The method of the invention typically comprises collecting the biological particles from a gaseous sample, contacting the biological particles with a first liquid reagent, extracting biological material from the collected biological particles, and analysing the biological material for the presence of a target nucleic acid sequence.

Method, chip, device and integrated system for detection biological particles

The present invention relates to a method, a chip, a device, and a system for collection of biological particles. The method makes use of electrostatic attraction of biological particles to charged electrodes and preferably operates with gaseous samples. The method, chip, device, and system are e.g. useful for collecting pathogenic particles, such as bacterial spores and vira, from air samples and allow for subsequent analysis of the collected biological particles.

The present invention relates to a method, a kit and a system for sensitive detection of a target nucleic acid molecule. The target nucleic acid molecule may e.g. be specific for a certain microorganism, e.g. a pathogenic microorganism such as B. anthracis. The methods and kits relate to so-called nested PCR and especially improvements, which renders the nested PCR technique better suited for automated analysis.
