Detection of Campylobacter in Air Samples May Offer New Monitoring System for Broiler Flocks

New research from Denmark suggests a promising method using air samples to continuously monitor broiler flocks for the presence of the foodborne pathogen Campylobacter. The findings are reported in the April 2009 issue of the journal Applied and Environmental Microbiology.

Campylobacter is one of the most common cause of diarrheal illnesses in humans worldwide. Research estimates that about half of the cases of human Campylobacteriosis originate from livestock, with poultry considered to be the most important source of infection. The slow and complicated process of detecting Campylobacter through culture-based identification has emphasized the need for more efficient detection devices and methodologies.

In the study researchers used the PCR method to detect Campylobacter in feces, dust, and air samples during the lifetime of broiler flocks in two poultry houses. Results showed that the sensitivity of detection of Campylobacter in air samples was comparable to detection in the other sample materials. Further monitoring of airborne particles in six poultry houses suggested that aerodynamic conditions depended on the age of the chickens, but were very comparable among different poultry houses. Lastly, researchers found that Campylobacter could be detected by PCR method in air samples collected only during the hanging stage of the slaughter process.

“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,” say the researchers.

    I am really loving the theme/design of your site.

    Do you ever run into any internet browser compatibility problems?
    A small number of my blog visitors have complained about my website not working correctly
    in Explorer but looks great in Chrome. Do you have any tips to help fix this

    I drop a comment whenever I appreciate a post on a site or if I have something to valuable to
    contribute to the conversation. Usually it’s triggered by
    the passion displayed in the post I read. And after this post Detection of Campylobacter in Air Samples
    May Offer New Monitoring System for Broiler Flocks | WEB lab.
    Unggas UGM. I was moved enough to create a comment 😉 I do have some questions for you if you tend not to mind.
    Could it be only me or do some of the responses come across like left by brain dead people?
    😛 And, if you are posting at additional social sites, I would like to keep up with anything new you have to post.
    Would you list all of your shared sites like your Facebook page, twitter feed, or linkedin profile?

    Asking questions are genuinely pleasant thing if you are not understanding
    something fully, however this post provides nice understanding yet.
