2. 1. Epidemiology of Enterococci with Acquired Resistance to Antibiotics in Sweden : Special emphasis on Ampicillin and Vancomycin

   Author : Erik Torell; Mats Kallin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Antimicrobial resistance; enterococci; epidemiology in Sweden; intra-hospital spread; shedding; risk-factors; infection; colonization; virulence factors; ARE; VRE; Php; PFGE; esp; gyrA; parC; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; infektionssjukdomar; Infectious Diseases;

   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

4. 2. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota

   Author : Nahid Karami; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ampicillin; tetracycline; in vivo fitness; persistence; gene transfer; intestinal; blaTEM Escherichia coli;

   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

5. 3. β-lactam combinations against multidrug-resistant Enterobacterales : Exploring combination effects and resistance development

   Author : Lisa Allander; Thomas Tängdén; Linus Sandegren; Pernilla Lagerbäck; Arnfinn Sundsfjord; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gram-negative bacteria; antibiotic combination therapy; antibiotic resistance; beta-lactams; beta-lactamase inhibitors; Infektionssjukdomar; Infectious Diseases;

   Abstract : The β-lactam antibiotics are a cornerstone in treating bacterial infections, but the increasing prevalence of antibiotic resistance worldwide threatens their effectiveness. The main driver of β-lactam resistance is the production of β-lactamases, which are bacterial enzymes that inactivate the antibiotic. READ MORE

6. 4. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

   Author : Ratana Lawung; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   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

7. 5. Antibiotic resistance in Lactobacillus reuteri and Lactobacillus plantarum

   Author : Maria Egervärn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   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.
