As part of the SENTRY Antimicrobial Surveillance Program, a total of 1078 Acinetobacter species and 842 Stenotrophomonas maltophilia isolates were collected between January 1997 and December 1999 from 5 geographic regions (Canada, the United States, Latin America, Europe, and the Asia-Pacific). The frequency of infections (by geographic region and body(More)

The authors have reviewed the clinical manifestations and therapy of hydrocephalus shunt infections in 32 patients with a total of 35 shunt infections. These 35 infections accounted for 43 hospital admissions. First infections usually developed within 2 months following surgery. At the time of diagnosis, 89% of patients were febrile. Fever and cough as a(More)
The majority of microbiology laboratories have implemented quality improvement procedures such as a Q scoring system to assess the nature of clinical specimens. Our study reviewed the sources and the amount of variation when Q scoring of lower respiratory secretions was performed. In total, 450 slides representing lower respiratory tract secretions were Q(More)
Records of 29,356 blood cultures performed between April 1994 and April 1997, using the BACTEC 9240 continuous monitoring blood culture system, were reviewed retrospectively. From these, 3,127 blood culture vials became positive. Of 95 blood culture isolates detected after three days of incubation, 63 were recovered on day four and 32 on day five.(More)
Between November 1 and 22, 1985, an outbreak of acute, nonbacterial gastroenteritis occurred in a 600-bed hospital in Toronto, Ontario, Canada. Illness in 635 of 2,379 (27%) staff was characterized by fatigue, nausea, diarrhea, and vomiting and had a median duration of 24-48 hours. The finding of virus-like particles measuring 25-30 nm in six stool(More)
A 29-year-old Chinese woman presented with a liver mass 2 months after initiation of chemotherapy for disseminated tuberculosis. A percutaneous liver biopsy revealed tuberculous pseudotumour. Although acid-fast bacilli were seen in the biopsy specimen, no organism could be cultured. No changes were made in the antituberculous chemotherapy, and the mass(More)
Early detection of methicillin-resistant S.aureus (MRSA) is critical for both the management of infected patients, and the timely institution of appropriate infection control measures. Although detection of the mecA gene by PCR remains the gold standard, this technology is inaccessible for many laboratories. Therefore, we sought to evaluate several new(More)
We evaluated four commercial transport systems with a standardized inoculum of clinical isolates of N. gonorrhoeae (NG), and assessed survival after holding for up to 48 hours at both ambient and refrigeration temperatures. Suspensions of clinical isolates of NG were standardized and adsorbed onto four transport swab types: Culturette EZ (Becton Dickinson(More)
The API Uriscreen is a rapid urine-screening test based on the detection of catalase activity present in somatic cells and in many of the bacteria commonly causing urinary tract infections. Of 487 routine, outpatient urine specimens processed by conventional quantitative culture, API Uriscreen, Vitek UID-3 panel, and a leukocyte esterase-nitrite strip, 142(More)
