Description

Two patients were reported as having been infectd with Bartonella henselae after having contact with a dog. Both of the patients owned a dog, but had no contact with cats.<BR>One patient was a 10-year-old boy who had experienced a fever of 38-39°C for 11 days, as well as having bilateral cervical lymphadenopathy. The boy's serum IgM antibodies to B. henselae were negative on the 6th and 16th day of his illness, whereas his IgG value, using indirect fluorescence antibody (IFA) method, was found to be elevated from 1: 256 to 1: 1, 024. B. henselae DNA was detected, by PCR method, in swabs from the gingiva and buccal membrane of the dog with which the boy had been in contact. The boy was first treated with cefdinir (300mg daily) for 6 days without beneficial effect. He responded, however, to minocycline (100mg daily) with symptom resolution in four days.<BR>The other patient was a 64-year-old man who had experienced a fever of 38-39°C for 27 days, as well as having right inguinal lymphadenopathy. The man's serum IgM antibody to B. henselae was negative, although his IgG value, determined by IFA, was 1: 1, 024. In addition, B. henselae DNA was detected, by PCR method, in parafin-embedded tissue obtained from the biopsied inguinal lymph nodes. The man was treated with cefazolin (2g daily). His fever resolved, but his lymph nodes remained swollen. After a regimen of erythromycin (1, 200mg daily), the swelling in his inguinal lymphnodes gradually disappeared.<BR>Careful review of suspected CSD victims' history of contact with animals is important in making a prompt diagnosis of B. henselae infection.
