The aim of the study is the evaluation of resistance patterns of E. coli in wastewater treatment plants without an evaluation of basic antibiotic resistance mechanisms. Investigations have been done in sewage, sludge and receiving waters from three different sewage treatment plants in southern Austria. A total of 767 E. coli isolates were tested regarding(More)
Among 149 extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae isolates collected from patients in southeast Austria from 1998 to 2004, 38 Escherichia coli isolates and 11 Klebsiella spp. were CTX-M producers. The proportion of CTX-M-producers among all ESBL producers rose from 0% in 1998 to 58% in 2004. In general, CTX-M-producers had(More)
The present study describes the effect of cadmium on lymphokines that cannot be directly traced to an allergen, or antigen in order to be able to explain various immunological processes. Exposure to various environmental pollutants is known to induce epithelial and inflammatory changes, characterized by a release of cytokines and other soluble mediators.(More)
The evaluation of airborne microorganisms in waste treatment facilities is complicated by different measuring systems, a lack of measuring standards and large variations between individual counts. In the present study, different sectors of the waste management industry were compared by determining median values of airborne culturable microorganisms from(More)
A 39-year-old healthy man developed a brain abscess weeks after a near-drowning incident. Scedosporium apiospermum, the anamorph of Pseudallescheria boydii, was isolated from the abscess. The patient died 153 days after the accident despite antifungal therapy. We discuss the role of antifungals and review the literature for comparable cases.
A total of 1163 I. ricinus ticks were collected in 3 different regions (15 localities) in Styria (Austria) in June 1997 and examined for the presence of spirochetes by dark field microscopy. The mean infection rate was 20.8%. Among 310 adults, 24.2% were positive and among 853 nymphs, 19.6% were positive. All 15 collection areas were shown to harbour(More)
The existence of human immunodeficiency virus type 1 (HIV-1) subtypes has many important implications for the global evolution of HIV and for the evaluation of pathogenicity, transmissibility, and candidate HIV vaccines. The aim of this study was to establish a rapid method for determination of HIV-1 subtypes useful for a routine diagnostic laboratory and(More)
Molecular detection of herpes simplex virus (HSV) DNA is recognized as the reference standard assay method for the sensitive and specific diagnosis of central nervous system infections caused by HSV. In this study, a molecular assay based on real-time PCR on the LightCycler (LC) instrument was evaluated and compared with a home-brew molecular assay. The(More)
