The susceptibilities of 43 pharyngeal isolates of Capnocytophaga to beta-lactam antibiotics, alone or in combination with beta-lactamase inhibitors, were tested by an agar dilution method. The 34 beta-lactamase-positive strains were highly resistant to beta-lactams, but the intrinsic activities of clavulanate, tazobactam, and sulbactam against Capnocytophaga, even beta-lactamase producers, indicates that these beta-lactamase inhibitors could be used for empirical treatment of neutropenic patients with oral sources of infection.

Waterhouse-Friderichsen syndrome caused by Capnocytophaga canimorsus septicemia was fatal in a previously healthy 47-year-old woman. The patient died suddenly in less than 12 hours after presentation, in spite of supportive measures, including ventilation, antibiotic coverage, pressor therapy, and multiple transfusions of blood products. The diagnosis of infection due to an unusual organism was suspected earlier in the course of management after review of the peripheral blood smear. The importance of the findings in the blood smear and their correlation with infection due to this organism are discussed.

Do not snog the dog: infective endocarditis due to Capnocytophaga canimorsus.

We present a case of prosthetic valve endocarditis and paravalvular abscess caused by the canine bacteria Capnocytophaga canimorsus in a 63-year-old man, who made a habit of snogging his pet dog. Capnocytophaga canimorsus can cause culture-negative endocarditis, therefore a high level of clinical awareness and the appropriate isolation techniques are important for making the diagnosis. Antibiotic therapy and properly timed excision of the infected focus are recommended.

Capnocytophaga canimorsus infections in human: review of the literature and cases report.
Lion C, Escande F, Burdin JC
Laboratoire de Bacteriologie, Centre Hospitalo-Universitaire de Nancy, France. Capnocytophaga canimorsus, formerly designated Dysgonic fermenter 2 (DF-2) was first described in 1976; it is a commensal bacterium of dogs and cats saliva, which can be transmitted to man by bite (54% of cases), scratch (8.5%), or mere exposure to animals (27%). We present a review of the clinical and microbiological characteristics of the Capnocytophaga canimorsus infections and 12 cases of infection in France. Over 100 cases of human infections have been reported, mainly septicemia in patients with diminished defences, due to splenectomy (33%), alcohol abuse (24%), immunosuppression (5%). However 40% of septicemia occur in patients with no predisposing conditions. Other infections are less frequent: meningitis, endocarditis, arthritis, pleural and localized eye infections. These infections range from mild to fulminating disease, with shock, respiratory distress, disseminated intravascular coagulation. Dermatological lesions (macular or maculopapular rash, purpura) or gangrene are common. This fastidious Gram-negative bacterium grows slowly on chocolate agar or on heart infusion agar with 5% rabbit blood incubated in 5% CO2. In spite of a great susceptibility of bacteria to antibiotics, the mortality is of 30%. Because of the severity of these infections, taking into account this organism in the management of bites is necessary, especially in patients with predisposing factors.

Capnocytophaga canimorsus septicemia in Denmark, 1982-1995: review of 39 cases.
Pers C, Gahrn-Hansen B, Frederiksen W
Department of Clinical Microbiology, Statens Seruminstitut Copenhagen, Denmark.
Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.

Vertebral osteomyelitis due to Capnocytophaga species in immunocompetent patients: report of two cases and review.
Duong M, Besancenot JF, Neuwirth C, Buisson M, Chavanet P, Portier H
Department of Infectious Diseases, Hopital du Bocage, Dijon, France.
Vertebral osteomyelitis caused by Capnocytophaga species was diagnosed in two adults. One of these infections was due to C. ochracea and the other was due to C. sputigena. Both patients were immunocompetent and presented with concomitant periodontitis and gingivitis. The infections were eradicated by means of prolonged antibiotic therapy, combined in one case with surgical treatment. Capnocytophaga species should be considered a potential cause of vertebral osteomyelitis in immunocompetent patients, especially in the presence of oral pathology.

Capnocytophaga sp. is a gram-negative bacilli, scarcely documented as the cause of bacteremias. Two cases of bacteremia caused by Capnocytophaga sp, one of them with endocarditis, are reported here. A review of previous published cases is also presented. One of the patients was immunocompromised, because of chemotherapy, the other, suffered from a rheumatic-cardiopathy which was complicated with endocarditis. Both patients developed an alteration of the oral mucosa. Antibiotic therapy proved to be effective with two patients.

Capnocytophaga canimorsus septicemia: fifth report of a cat-associated infection and five other cases.
Valtonen M, Lauhio A, Carlson P, Multanen J, Sivonen A, Vaara M, Lahdevirta J
Department of Medicine, Helsinki University Central Hospital, Finland.
Capnocytophaga canimorsus is a fastidious, slow-growing, gram-negative, rod-shaped bacterium that belongs to the normal oral flora of dogs and cats. Human septicemic infections are associated with a high mortality; most cases occur in immunocompromised patients with a history of dog bite. The fifth case of cat-associated septicemia caused by Capnocytophaga canimorsus is described. The six case reports presented here point out the characteristics reported previously: (a) cats are a source of human infection; (b) alcohol abuse is an important risk factor for the development of septicemic Capnocytophaga canimorsus infection; (c) septicemic infection often manifests with disseminated intravascular consumption coagulopathy or purpura; and (d) some cases of septicemia in humans result from pets that lick skin ulcers.
