Urinary tract infections are quite common in dogs. (They’re uncommon in cats, but a lot of cats get treated with antibiotics for non-infectious urinary tract disease.) An important aspect of managing urinary tract infections (UTIs) is getting a proper diagnosis. Diagnosing a UTI involves a few different things:
One of the common questions accompanying the onslaught of calls I’ve taken today is "How do you diagnose influenza in pets?"
Clinical signs, such as sneezing, coughing, fever and lethargy, are not useful for diagnosis. Influenza can produce highly variable disease, ranging from almost none to very severe – so you can’t
As public awareness of zoonotic diseases increases, some new marketing opportunities are created. One is offering screening of pets for "protection" of the family. One company, Healthgene, offers a Family Protection Program that involves screening pets for selected zoonotic pathogens. Unfortunately, it involves the use of non-validated PCR tests for pathogens for which screening
Tuttle Animal Medical Center in Florida has reported six dogs with severe bloody diarrhea, vomiting and fever, over the past month. The affected dogs were from the same general area in Sarasota County, and all but one died within 24 hours. However, care must be taken when interpreting information such as this

Testing in certain situations is useful, but this is almost always limited to diagnosis of animals with active infections (i.e. they’re
If your veterinarian suspects your pet may have ringworm, there are several different ways he or she may test for the causative fungus (a dermatophyte) on your animal’s fur and skin. Some of these techniques are more useful than others in different situations.
An important step in diagnosing infectious diseases and determining the optimum approach to treatment and management is rapid and accurate diagnostic testing. Many different testing methods are used, particularly bacterial culture (at least for bacterial diseases). Molecular testing has revolutionized the field of microbiology, and is making inroads into the field of diagnostic testing. Polymerase
