We studied all patients with community-acquired pneumonia who were admitted to our 800-bed adult acute care hospital from 1 November 1981 to 15 March 1987. The 719 patients had a mean age of 63.2 years; 18% were admitted from nursing homes, and 18% required ventilatory assistance as part of the therapy for pneumonia. Patients with nursing home-acquired(More)
4 patients with atypical pneumonia and a history of exposure to wild rabbits were found to have antibodies to Coxiella burnetii but not to the other organisms also commonly associated with atypical pneumonia. 10 (45%) of 22 snowshoe hares caught in the area where 1 of the patients snared his rabbits had antibodies to Coxiella burnetii. Q fever ought to be(More)
We used an indirect immunofluorescence assay to determine antibody titers to phase I and phase II Coxiella burnetii antigens in serum samples from a variety of wild animals in Nova Scotia. Forty-nine percent of the hares, 16.5% of the moose, 7.1% of the raccoons, and 1.5% of the white-tailed deer tested had antibodies to phase I antigen. We conclude that(More)
We describe an outbreak of Q fever affecting 16 of 32 employees at a truck repair plant. None of the cases were exposed to cattle, sheep or goats, the traditional reservoirs of Q fever. The cases did not work, live on, or visit farms or attend livestock auctions. One of the employees had a cat which gave birth to kittens 2 weeks prior to the first case of Q(More)
There is very little information available about the prevalence of Coxiella burnetii in Africa. We obtained blood from 75 Nigerians hospitalized in Sokoto for a variety of acute medical conditions. Their age range was 7 months to 50 years; there were 39 males and 36 females. Antibody titers were determined to phase I and phase II C. burnetii antigens using(More)
Twenty-eight previously unreported cases of appendiceal diverticula were found in a 15-year retrospective review of records at five hospitals. The incidence is probably higher than is realized. Data drawn from the review indicated that the age of the patient and a history of previous attacks might be slight clues to distinguishing between diverticulum and(More)
PURPOSE To define the etiology of pneumonia, using a battery of serological tests, among patients presenting to physicians' offices in Cumberland County, Nova Scotia from July 2, 1989 to July 1, 1990. METHODS Patients presenting to their physician's office with symptoms suggestive of pneumonia were invited to participate in the study by completing a(More)
Thirty-three cases (24 definite, nine probable) of Q fever were diagnosed in Victoria County, Cape Breton, Nova Scotia from May to August, 1985. Twenty-six of the cases occurred in residents of Baddeck (population 900, attack rate 2.8 percent), and 21 of the cases occurred during the month of June. There was geographic clustering of the cases: 14 of the 33(More)
