Transmission routes for the bacterium Campylobacter

11.12.2006
Campylobacter is the most frequently reported human bacterial enteric pathogen, in Norway as well as in other countries. The number of diseased has been continuously increasing during the last 15

According to the official statistics, approximately 1200 persons are domestically infected with Campylobacter each year, but the true number is probably much higher according to Gro Johnsen. She has done research on Campylobacter, and defended recently her PhD thesis at the Norwegian School of Veterinary Science.

Consumption of poultry meat purchased raw, for instance broiler fillet, is regarded as a risk factor for acquiring the disease. Campylobacter is decimated through food production, but the bacterium is readily transmitted to salad and other ready-to-eat foods due to poor kitchen hygiene and cross contamination from contaminated utensils, Johnsen says.

Surprising results

Johnsen has studied the transmission routes for Campylobacter, from environment on to live broilers at farm, and cross contamination in the slaughterhouse. She found extensive presence of Campylobacter on the courtyards, and that infected drinking water and lacking hygienic routines caused infection of the broilers.

- A surprising finding was the high prevalence of Campylobacter in surface water in the vicinity of the broiler farms, Johnsen tells. It is well known that the bacterium can be isolated from water, but that it can be so commonly found is worrying.

Johnsen also found that the carcasses and the slaughterhouse environment, including the air, were considerably contaminated during the slaughtering of infected flocks.

To prevent Campylobacter infecting the live poultry at farm, proper hygienic barriers and clean disinfected drinking water are important. During slaughter, measures have to be implemented to prevent the transmission of Campylobacter to clean carcasses, to the slaughterhouse workers and to prevent infected retail products to be distributed.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
