2. 1. 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

4. 2. 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.

5. 3. Species specific susceptibility testing for ß-lactam antibiotics. With special reference to staphylococci

   Author : Ann Cathrine Petersson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; beta-lactamase; staphylococcus; methicillin resistance; Microbiology; mecA susceptibility testing; virologi; mykologi;

   Abstract : The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?.

6. 4. Molecular epidemiology of coagulase-negative staphylococci in hospitals and in the community

   Author : Micael Widerström; Johan Wiström; Tor Monsen; Anders Sjöstedt; Bo Söderquist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; staphylococcus epidermidis; staphylococcus saprophyticus; electrophoresis; gel; pulsed-field; genetic diversity; methicillin-resistance; UTI; drug resistance; multiple; bacterial; epidemiology; molecular; cross infection; molecular sequence data; Medical microbiology; Medicinsk mikrobiologi; Clinical bacteriology; Klinisk bakteriologi; Infectious diseases; Infektionssjukdomar; Clinical Bacteriology; klinisk bakteriologi; mikrobiologi; Microbiology; Infectious Diseases; infektionssjukdomar;

   Abstract : Background Coagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). READ MORE

7. 5. Development of an Ultrasensitive Capacitive DNA-sensor: A promising tool towards microbial diagnostics

   Author : Ally Mahadhy; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive DNA-sensor; Enterobacteriaceae; mecA gene; Methicillin resistance; automated sequential injection analysis; sandwichhybridization; elevated temperature; polytyramine;

   Abstract : Fast and sensitive detection of pathogenic microbial cells is a highly important task in medical diagnostics, environmental analysis and evaluation of food safety. Accordingly, the idea of microorganism identification by the recognition of specific DNA sequence using electrochemical technique is one of the leading researches in the development of diagnostic devices.
