Investigation of motility and biofilm formation by intestinal Campylobacter concisus strains
Motility helps many pathogens swim through the highly viscous intestinal mucus. Given the differing outcomes of Campylobacter concisus infection, the motility of eight C. concisus strains isolated from patients with Crohn's disease (n=3), acute (n=3) and chronic (n=1) gastroenteritis and a healthy control (n=1) were compared. Following growth on solid or liquid media the eight strains formed two groups; however, the type of growth medium did not affect motility. In contrast, following growth in viscous liquid medium seven of the eight strains demonstrated significantly decreased motility. In media of increasing viscosities the motility of C. concisus UNSWCD had two marked increases at viscosities of 20.0 and 74.7 centipoises. Determination of the ability of UNSWCD to swim through a viscous medium, adhere to and invade intestinal epithelial cells showed that while adherence levels significantly decreased with increasing viscosity, invasion levels did not significantly change. In contrast, adherence to and invasion of UNSWCD to mucus-producing intestinal cells increased upon accumulation of mucus, as did bacterial aggregation. Given this aggregation, we determined the ability of the eight C. concisus strains to form biofilms, and showed that all strains formed biofilms. In conclusion, the finding that C. concisus strains could be differentiated into two groups based on their motility may suggest that strains with high motility have an increased ability to swim through the intestinal mucus and reach the epithelial layer.
Ultrasonic bug zappers don't help ward off bedbugs
It sure is tempting: Just plug in a device and let sound waves keep bedbugs and other creepy-crawlies away, without pesticides or expensive exterminator bills. Unfortunately, those ultrasonic bug repellent devices marketed on late-night TV and sold online don't work,...
In this simple veggie side dish, all you need to do is dress broccoli with olive oil and season with a hint of salt to bring out its naturally hearty flavor. The scent of Parmesan cheese will attract hungry mouths to the table and the earthy taste of freshly roasted broccoli will have them coming back for more.
Tempeh is marinated in a ginger lime dressing and then tossed with refreshing crisp veggies like sugar snap peas, asparagus, carrots, corn, bell peppers and scallions. The earthy tempeh pairs well with the hearty, whole wheat soba noodle and the veggies in this dish can be adapted easily to suit any season.
Rather than putting your body through harsh fasts or detox programs, take a gentle approach to cleansing and detoxifying your body with an herbal fiber supplement. Fiber works to slowly yet thoroughly cleanse the digestive system without disrupting daily life.

Prescription for Nutritional Healing By Phyllis A. Balch, CNC
Prescription for Nutritional Healing is the most thorough drug-free guide to managing chronic conditions I have ever come across. It is an 800 page, A to Z, guide providing alternative and holistic approaches to almost every common disease. I highly recommend this book to anyone, especially practicing dietitians, looking to expand their holistic knowledge. If you, like me, consistently counsel patients not responding to or interested in Western Medicine, then this is your answer.
