Resistance to antibiotics: limit theorems for a stochastic SIS model structured by level of resistance

Phenotypic Resistance to Antibiotics

The development of antibiotic resistance is usually associated with genetic changes, either to the acquisition of resistance genes, or to mutations in elements relevant for the activity of the antibiotic. However, in some situations resistance can be achieved without any genetic alteration; this is called phenotypic resistance. Non-inherited resistance is associated to specific processes such a...

Limit Theorems for Solutions of Stochastic

Exact rates of convergence which are of the law of the iterated logarithm type are investigated for recursive stochastic diierence equations in Ba-nach spaces. The results are applied to autoregressive processes and to an averaging method.

Propionibacterial resistance to antibiotics in patients with Acne Vulgaris

Background: Acne vulgaris is a self-limited disease that mainly involves the sebaceous follicles. Systemic antibiotic is a common therapeutic modality, so bacterial resistance can be a problem. Objectives: Assessment of Propionibacterium resistance to erythromycin, tetracycline, clindamycin and spiramycin. Patients and Methods: Sampling was done on lesions of 123 patients with acne vulgaris who...

Development of Resistance to Antibiotics

Widespread use and misuse of penicillin and other antibiotics have resulted in development of resistance most antibiotics. The mechanisms by which microorganisms develop resistance to antibiotics are discussed. Topics covered include acquisition of point mutations and antibiotic resistance genes, methods of transfer of resistance genes between bacteria, and the advantages of synthetic antibioti...
