Bacterial resistance to antibiotics is a growing clinical problem and public health threat. Antibiotic use is a known risk factor for the emergence of antibiotic resistance, but demonstrating the causal link between antibiotic use and resistance is challenging. This review describes different study designs for assessing the association between antibiotic use and resistance and discusses strengt...

conclusions it seems that besides the variety and prevalence of blatem and blactx, enormous mechanisms such as porin and leaking systems (efflux pumps) are responsible for the information of the a. baumannii resistance to disinfectants. the study on an accurate consideration of the resistance in strains and other microorganisms is advised. results in the current study, 131 a. baumannii isolates...

Alternatives to antibiotics are urgently needed in animal agriculture. The form these alternatives should take presents a complex problem due to the various uses of antibiotics in animal agriculture, including disease treatment, disease prevention, and growth promotion, and to the relative contribution of these uses to the antibiotic resistance problem. Numerous antibiotic alternatives, such as...

OBJECTIVES To study the minimum inhibitory concentrations (MICs) of Propionibacterium acnes (P. acnes) isolates to selected antibiotics from patients with acne vulgaris in Singapore and determine if resistance increases with prolonged use of antibiotics. DESIGN A single-centre prospective study. SETTING Tertiary dermatological referral centre in Singapore. PATIENTS One hundred and fifty p...

Introduction: Based on the World Health Organization reports, infections caused by ampicillin-resistant Haemophilus influenzae strains are a major threat to public health and need urgent therapy with new antibiotics. Given the lack of a previous comprehensive study on the prevalence of the antibiotic resistance of H. influenzae in Iran, this systematic review and meta-analysis was perform...

The evolution of antibiotic resistance among bacteria threatens our continued ability to treat infectious diseases. The need for sustainable strategies to cure bacterial infections has never been greater. So far, all attempts to restore susceptibility after resistance has arisen have been unsuccessful, including restrictions on prescribing [1] and antibiotic cycling [2], [3]. Part of the proble...

BACKGROUND The use of antibiotic drugs triggers a complex interaction involving many biological, sociological, and psychological determinants. Resistance to antibiotics is a serious worldwide problem which is increasing and has implications for morbidity, mortality, and health care both in hospitals and in the community. OBJECTIVES To analyze current research on the determinants of antibiotic...

Different theories have been proposed to understand the growing problem of antibiotic resistance of microbial populations. Here we investigate a model that is based on the hypothesis that senescence is a possible explanation for the existence of so-called persister cells which are resistant to antibiotic treatment. We study a chemostat model with a microbial population which is age-structured a...

Introduction: Urinary tract infection is a common bacterial infection in childhood . Approximately 3-5% of girls and 1% of boys acquire a urinary tract infection (UTI). The management of UTI is complicated by the increasing prevalence of antibiotic- resistant strains and over the - counter antibiotics empiric therapy with antibiotics such as ampicillin , amoxicillin and cotrimoxazo...

Background Antibiotic resistance is a growing problem worldwide, but communicating this challenge to policymakers and non-experts is complicated by the multiplicity of bacterial pathogens and the distinct classes of antibiotics used to treat them. It is difficult, even for experts aware of the pharmacodynamics of antibiotics, to infer the seriousness of resistance without information on how com...
