1. Epidemiology of Enterococci with Acquired Resistance to Antibiotics in Sweden : Special emphasis on Ampicillin and Vancomycin
Abstract : The first hospital outbreak of vancomycin-resistant enterococci (VRE) and carriage rates of VRE and ampicillin-resistant enterococci (ARE) in Sweden were investigated. Clonal relationships and mutations in fluoroquinolone resistance determining regions among ARE collected nation-wide were studied. READ MORE

2. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota
Abstract : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. READ MORE

3. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis
Abstract : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. READ MORE

4. Antibiotic resistance in Lactobacillus reuteri and Lactobacillus plantarum
Abstract : Lactic acid bacteria (LAB) may act as reservoirs of antibiotic resistance genes that can be transferred via the food chain or within the gastrointestinal tract to pathogenic bacteria. This thesis provides data required for assessing the potential risk of using antibiotic resistant strains of the LAB species Lactobacillus reuteri and Lactobacillus plantarum as food processing aids or probiotics.

5. Molecular epidemiology of clinical Enterococcus faecium
Abstract : Enterococci are today the third most commonly isolated species from bloodstream infections, and problems with ampicillin and vancomycin resistance are increasing. Some putative virulence factors such as the enterococcal surface protein (Esp) and hyaluronidase (Hyl) have been described in Enterococcus faecium. READ MORE
