Giardia in symptomatic dogs and cats in Europe--results of a European study.
The percentage of Giardia infection in dogs and cats with gastrointestinal signs presenting to clinics was examined across Europe using the IDEXX SNAP Giardia Test (IDEXX Laboratories). Veterinary practices were asked to identify diarrheic and/or vomiting dogs and cats and to use the test on fecal samples from these animals. A selection for "asymptomatic" testing was also available on the data collection sheet for testing that occurred outside the target "symptomatic" population. Results from 8685 dogs and 4214 cats were submitted during the sampling period from 2005 to 2006. Analysis of the data showed 24.78% of the samples positive for Giardia among tested dogs and 20.3% among tested cats. The younger the dog or the cat, the higher the risk of being positive, peaking in the category below 6 months. The main clinical symptom, diarrhoea, also showed a higher risk of being positive, OR's of acute diarrhoea were almost double of those of the category "asymptomatic" for dogs or cats, the same range was calculated for chronic diarrhoea. Differences in participating countries were also seen. The risk of being positive was half or less in UK, Spain, Netherlands, Italy compared to Germany, and only in Belgium it showed to be higher. The results of this study show that Giardia is a common enteric agent among dogs and cats with gastrointestinal signs in Europe.
