  1. 1. Antibiotic-Regulated Plasmid Copy Number Variation: A Driver of Antibiotic Resistance?

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Ahmed Eldek; [2019]
    Keywords : antibiotic resistance; plasmid copy number; ddPCR;

    Abstract : Plasmids are small circular DNA molecules within bacterial cells that are separated from the bacterial chromosome and replicate independently. Also, they play a crucial role in the dissemination of antibiotic resistance genes among bacteria through horizontal gene transfer. READ MORE

  3. 2. Growth Dynamics, Antibiotic Susceptibility and the Effect of Sublethal Ciprofloxacin Concentrations in Susceptible and Resistant Escherichia coli in Biofilm

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Jenny Fernberg; [2019]
    Keywords : Biofilm; Escherichia coli; CFT073; BPC; MBIC; MSC; Ciprofloxacin; Streptomycin; Rifampicin; Antibiotic resistance; Urinary Tract Infections; Growth dynamics; Antibiotic susceptibility; S83F; K42N; S531L; Sub-MIC;

    Abstract : Instead of planktonic growth in nature, many species of bacteria form biofilm to survive in harsh conditions. Although many chronic bacterial infections are caused by bacterial species in a biofilm lifestyle, previous research has focused on studying antibiotic resistance in planktonic growth. Here we used a modified MBEC assay, i.e. READ MORE

  4. 3. Mekanismer hos tillväxtfrämjande antibiotika

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Miranda Blad; [2019]
    Keywords : tillväxtfrämjande; antibiotika; produktionsdjur;

    Abstract : Antibiotika har använts inom djurproduktion i tillväxtfrämjande syfte sedan den effekten uppdagades för över 50 år sedan. Med en ökande resistensproblematik har dock användningen ifrågasatts och i stora delar av världen även förbjudits. READ MORE
