1. Daptomycin to bone and joint infections and prosthesis joint infections: a systematic review
ABSTRACT Backgroud: Daptomycin has been used in bone and joint infections (BJI) and prosthesis joint infections (PJI) considering spectrum of activity and biofilm penetration. However, the current experience is based on case reports, case series, cohorts, and international surveys. The aim of this systematic review was to evaluate studies about daptomycin t

2. Atividade antimicobacteriana, citotoxicidade e interaÃÃo com macrÃfagos J774 de lipossomas contendo Ãcido Ãsnico
Secondary lichen metabolite usnic acid (UA) [2,6-diacetyl-7,9-dihydroxy-8,9b-dimethyl-1,3(2H,9bH)-dibenzofurano] is known by its antimicrobial activity against gram-positive bacteria and mycobacteria. Pulmonary tuberculosis is characterized by involvement of macrophages containing inside a large number of Mycobacterium tuberculosis. Liposomes have long been

3. Estudo da disposição cinética da cefuroxima em pacientes submetidos à cirurgia de revascularização do miocárdio com circulação extracorpórea e hipotermia / Cinetic disposition of cefuroxime in coronary artery bypass graft surgery with Cardiopulmonary bypass and hypothermia
Cardiopulmonary bypass and hypothermia (HCPB) is a procedure commonly used during heart surgery, representing a risk factor for the patient by promoting extensive hemodilution and profound physiological changes. Cefuroxime is used for the prophylaxis of infection after heart surgery and its minimum inhibitory concentration (MIC90) may vary from 4 to 16 µ

4. Transmission Electron Microscopic Study of Antibiotic Action on Klebsiella pneumoniae Biofilm
The penetration of ampicillin and ciprofloxacin through biofilms formed by Klebsiella pneumoniae was confirmed by transmission electron microscopic observation of antibiotic-affected cells at the distal edge of the biofilm. Because the bacteria nevertheless survived antibiotic treatment, some protective mechanism other than inadequate penetration must have b

7. Theoretical aspects of antibiotic diffusion into microbial biofilms.
Antibiotic penetration into microbial biofilm was investigated theoretically by the solution of mathematical equations describing various combinations of the processes of diffusion, sorption, and reaction. Unsteady material balances on the antibiotic and on a reactive or sorptive biomass constituent, along with associated boundary and initial conditions, con

8. Contributions of Antibiotic Penetration, Oxygen Limitation, and Low Metabolic Activity to Tolerance of Pseudomonas aeruginosa Biofilms to Ciprofloxacin and Tobramycin
The roles of slow antibiotic penetration, oxygen limitation, and low metabolic activity in the tolerance of Pseudomonas aeruginosa in biofilms to killing by antibiotics were investigated in vitro. Tobramycin and ciprofloxacin penetrated biofilms but failed to effectively kill the bacteria. Bacteria in colony biofilms survived prolonged exposure to either 10

9. Evaluation of the penetration of ciprofloxacin and amoxycillin into the bronchial mucosa.
The concentrations of two antibiotics, amoxycillin and ciprofloxacin, were measured by microbiological assay in serum and in bronchial mucosa obtained at fibreoptic bronchoscopy in 38 patients undergoing diagnostic bronchoscopy for a range of respiratory symptoms. Patients had taken one of the two drugs orally for four days before bronchoscopy. The percentag

12. Penetration of Rifampin through Staphylococcus epidermidis Biofilms
Rifampin penetrated biofilms formed by Staphylococcus epidermidis but failed to effectively kill the bacteria. Penetration was demonstrated by a simple diffusion cell bioassay and by transmission electron microscopic observation of antibiotic-affected cells at the distal edge of the biofilm.
