Effective chemotherapy of tuberculosis requires rapid assessment of drug sensitivity because of the emergence of multidrug-resistant Mycobacterium tuberculosis. Drug susceptibility was assessed by a simple method based on the efficient production of photons by viable mycobacteria infected with specific reporter phages expressing the firefly luciferase gene. Light production was dependent on pha...

silicosis is considered to be among the occupational lung diseases and associated with sandblasting, mining, quarrying and tunneling. acute silicosis is usually progressive diseaseand despite treatment with corticosteroids it leads to cardio-respiratory failure and death. alveolar silicoproteinosis is one of it’s acute presentations due to exposure to silica dust and lungs filling with proteina...

background methicillin-resistant staphylococcus aureus (mrsa) remains a significant public health problem and treatment challenge. objectives this study was conducted to determine the frequency, molecular types, and drug resistance of s. aureus isolated from nasal carriers in two teaching hospitals (hajar and kashani) in shahrekord, southwestern iran. methods in this cross-sectional study, 262 ...

We examine the dynamics of infection by the human immunodeficiency virus (HIV), as well as therapies that minimize viral load, restore adaptive immunity, and use minimal dosage of anti-HIV drugs. Virtual therapies for wild-type infections are demonstrated; however, the HIV infection is never cured, requiring continued treatment to keep the condition in remission. With high viral turnover and mu...

A current phenomenon of great concern among the medical communities in developing countries is rising multi-drug resistant organisms, and the challenges of curing the infections in children. In this study, we evaluated the multi drug resistant strains of Escherichia coli isolated from urinary tract infection in children in southern Iran. Totally, 90 strains of E. coli were collected from urine ...

PURPOSE To evaluate the clinical features and treatment outcomes of patients with pulmonary tuberculosis, stratified by level of drug resistance. METHODS This was a historical cohort study based on data from the II National Anti-Tuberculosis Drug Resistance Survey (2006-2007) collected at eight participating health care facilities in Porto Alegre, southern Brazil. The cohort was followed for ...
