“It is feasible to use a dog to detect Clostridium difficile in stool samples and in patients. The dog’s diagnostic accuracy with stool samples suggests that immediate identification of C difficile is possible. Moreover, our data suggest that the same may be true for the rapid diagnosis of C difficile infection on clinical wards. For the purposes of detection the dog did not need a stool sample or physical contact with patients. It would seem dogs can detect C difficile in the air surrounding patients. In addition, dogs are quick and efficient: patients in a hospital ward can be screened for the presence of C difficile infection in less than 10 minutes.” Read entire study below to find more information on methods and results.

New Research; how odor is processed

“For most animals, smell is a very, very important thing,” said Harvard Professor Venkatesh Murthy. “If they are in an environment where there’s one overwhelming smell that’s irrelevant, they need to be able to detect a weak smell that may signal danger.” Earlier studies had hinted that the interneurons in the olfactory bulb are the primary . . . → Read More: New Research; how odor is processed

Handlers’ Beliefs Affect Explosive- And Drug-Sniffing Dog Performance
02 Feb 2011
Drug- and explosives-sniffing dog/handler teams’ performance is affected by human handlers’ beliefs, possibly in response to subtle, unintentional handler cues, a study by researchers at UC Davis has found. Continue reading Handlers’ beliefs & Drug Dog Performance

The high mortality rate associated with ovarian carcinoma is mainly owing to late diagnosis. It is thus essential to develop inexpensive and simple methods for early diagnosis. Papers on canine scent detection of malignancies such as melanoma and bladder, lung, and breast cancer have recently been published in peer-reviewed journals, indicating a new diagnostic tool for malignancies.
