We assessed the clinical relevance and performed molecular characterization of 36 multidrug-resistant strains of Corynebacterium striatum. Pulsed-field gel electrophoresis confirmed a single clone, possessing erm(X), tetA/B, cmxA/B, and aphA1 genes, but few related subclones. This strain is emerging as a pathogen in Italy.
BACKGROUND Community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA) is responsible for severe infections in previously healthy people acquired in the community in different areas of the world. AIM To report an outbreak of CA-MRSA in a hospital newborn nursery in northern Italy in September-October 2010, its investigation and control(More)
Twenty-six patients were implicated in a nosocomial pseudo-outbreak of Fusarium verticillioides. Examination of clinical records and handling procedures revealed a fungal contamination of supposedly sterile containers used for biological materials. An accurate system of monitoring permitted us to determine the origin of the infection and the means of its(More)
From June to September 1988, an outbreak of Pseudomonas aeruginosa infections in neutropenic patients admitted to the Haematological Wards of “Ospedali Riuniti” in Bergamo, Italy, was detected. Out of 11 cases of P. aeruginosa infections, 8 were bacteremic. Of these, 7 died within few days of onset (mortality rate: 87.5%). Consequently, possible sources of(More)
The clinical files of patients admitted to the Ospedali Riuniti of Bergamo between January 1984 and December 1987 in which the presence of mycobacteria has been demonstrated have been reviewed. We have analysed the clinical pattern and the complicating diseases and we have reported the typing of mycobacteria in comparison with the literature data. We stress(More)
During the 1989 calendar year, P. aeruginosa caused clinical infections in 0.46% of patients admitted to Ospedali Riuniti (a general hospital), Bergamo, Italy. Strains (n = 267) of P. aeruginosa were collected during this period, and epidemiological characteristics were studied. The mean prevalence of P. aeruginosa infection in inpatients was 1.1% (range(More)
We describe the emergence of three thymidine-dependent strains (Thy-): two Escherichia coli obtained in successive occasions from urine of a woman treated with co-trimoxazole before the organisms were isolated and one Proteus mirabilis obtained from urine of a man who had a treatment with norfloxacin. Cultural characteristics and methods for the detection(More)
The Authors note their experience of dealing with data in a microbiology laboratory using the Olivetti TES 501 system. This system permits a rational organisation of the work programme, from writing out the work sheets, simultaneous type-out of results, filing, to the possibility of rapid consultation of records, etc. According to the Authors, however, its(More)
A study was undertaken to evaluate the sensitivity, accuracy and practicability to a two-bottle nonradiometric blood culture system (BACTEC NR 660) with the two bottle conventional blood culture system in use in our laboratory. A total of 592 sets of four blood culture bottles were collected from adults in a twenty-week period, giving 126 positive sets. The(More)
The Liquoid-BHI, biphasic blood culture system, was compared with a conventional blood culture bottle (Hemoline performance diphasique) in 3125 paired blood cultures. Both systems were inoculated with equal volumes of blood (5 ml). Streptococcus spp. (P less than 0.02) and S. epidermidis (P less than 0.05) were recovered from BHI system. In contrast, P.(More)
