2. 1. Staphylococcus aureus : aspects of pathogenesis and molecular epidemiology

   Author : Lisa Stark; Per-Eric Lindgren; Sture Löfgren; Erik Kihlström; Jan Strindhall; Andreas Matussek; Johanna Ericson Sollid; Linköpings universitet; []
   Keywords : ;

   Abstract : Staphylococcus aureus is a human commensal colonizing about 30 per cent of the population. Besides, it is a frequent cause of infections such as skin, wound and deep tissue infections and also more life-threatening conditions such as pneumonia, endocarditis and septicaemia. S. aureus may also cause different toxicoses. READ MORE

4. 2. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

   Author : Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; Microbiology; Mikrobiologi;

   Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE

5. 3. Molecular epidemiology of methicillin-resistant staphylococcus aureus : epidemiological aspects of MRSA and the dissemination in the community and in hospitals

   Author : Carolina Berglund; Bo Söderquist; Teruyo Ito; Ulf Tidefelt; Johanna Ericson Sollid; Örebro universitet; []
   Keywords : methicillin-resistant Staphylococcus aureus MRSA ; community-acquired MRSA CA-MRSA ; staphylococcal cassette chromosome mec SCCmec ; multilocus sequence typing MLST ; horizontal transfer; Panton Valentine leukocidin PVL ; MEDICINE; MEDICIN; Medicin; Medicine;

   Abstract : Methicillin-resistenta Staphylococcus aureus (MRSA) som bär på genen mecA, har förekommit och spridit sig över hela världen, främst i sjukhusmiljö, och orsakat utbrott av vårdrelaterade (så kallade nosokomiala) infektioner. Dessa infektioner kan inte behandlas med stafylokock-penicilliner och MRSA-bakterierna är ofta resistenta även mot flera andra grupper av antibiotika vilket medför att infektionerna ofta är påtagligt svårbehandlade.

6. 4. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

   Author : Rong Cao; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

   Abstract : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. READ MORE

7. 5. Serum antibodies against Staphylococcus aureus antigens in healthy individuals and patients with invasive infections

   Author : Patricia Colque-Navarro; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The present work aims to study the antibody responses against Staphylococcus aureus in health and in deep infections and is composed of six papers. We developed a sandwich enzyme immuno assay (EIA) with a detection limit for alpha-toxin at nanograms levels. READ MORE
