1. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota
Sammanfattning : 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. LÄS MER
2. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis
Sammanfattning : 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. LÄS MER
3. Antibiotic resistance in Lactobacillus reuteri and Lactobacillus plantarum
Sammanfattning : 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.
