Is Capnocytophaga aerobic or anaerobic?
Capnocytophaga spp. are long, thin gram-negative bacilli that are slow growing, with gliding ability on agar media. They are facultatively anaerobic and require enrichment with CO2 (5-10%) for optimum growth (capnophilic). The organisms grow best at 35 to 37 °C on either blood or chocolate agar.
Is Capnocytophaga oxidase positive?
sputigena is oxidase- and catalase-negative and may cause severe periodontitis and other opportunistic infections in humans. 3. Which of the following resistance mechanisms may be found in multidrug-resistant Capnocytophaga sputigena? a.
What does Capnocytophaga do to humans?
In both types of infections—those that spread from animals or from oneself—the bacteria can enter the blood stream, which can lead to infection in various parts of the body. Infection can also cause the following: Septicemia (blood infection) Endocarditis (inflammation of the lining of the heart)
Is Capnocytophaga canimorsus indole negative?
The major phenotypic characteristics of C. canimorsus include positive test results for oxidase, catalase, arginine dihydrolase, and o-nitrophenyl-β-d-galactopyranoside and negative reactions for urease, nitrates, and indole.
Is Capnocytophaga catalase positive?
With three rapid identification methods, negative catalase and oxidase reactions and positive ONPG assay, Capnocytophaga was easily separated from Eikenella corrodens, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, and CDC group DF-2.
How do you identify Capnocytophaga?

What is a Dysgonic fermenter?
Dysgonic fermenter 2 (DF-2) is a slow-growing gram-negative bacillus causing a zoonotic infection that is acquired through dog bites or other contact with dogs. Splenectomized patients and those with alcoholic liver disease are most susceptible to DF-2 infection.
What kills Capnocytophaga?
Capnocytophaga infection can be treated with prescription medicine called antibiotics. Antibiotics kill bacterial germs like Capnocytophaga. It is important to call your doctor if you have been bitten by a dog or cat or believe that you might be infected with Capnocytophaga germs.
How do you test for Capnocytophaga?
What tests diagnose Capnocytophaga infections? Doctors diagnose Capnocytophaga canimorsus by detecting it in the blood by growing the bacterium in cultures performed in a microbiology laboratory. Blood cultures may detect most bacteria (“become positive”) within 1 to 2 days of incubating the blood in the lab.
Should I worry about Capnocytophaga?
Capnocytophaga, as hard to treat as it is to pronounce, is a common bacteria found in our pets. While harmless to cats and dogs, it can cause serious health problems in humans. So, should we be worried about it? Experts say probably not.
