The adherence to the principles of rational antibacterial therapy is great significance, namely prescription a medication achieve quickest possible clinical and bacteriologic convalescence, spectrum mechanisms drug should affect germ, overcome resistance make highest concentration in infectious focus. Moreover, prescribed be convenient for outpatient usage. important principle infection treatme...

The antibacterial properties of aflatoxin B1 have been evaluated against antibiotic-resistant clinical isolates of Escherichia coli and Staphylococcus aureus. The inhibition of growth ranged from 11.5 to 60.0% and 4.5 to 18.5% in the strains of S. aureus and E. coli, depending on the extent of drug resistance. Aflatoxin-B1 binding varied with toxin concentration, the presence of surfactants (Tw...

AIM The aims of the present study were to determine the antibiotic susceptibility profils with particular emphasis on susceptible or resistant strains to macrolides and lincosamids antibiotics and to determine possible antibiotic resistance mechanisms occurring in group B streptococci (GBS) strains using PCR assay and disk diffusion method. METHODS A total of 62 clinical GBS strains were inve...

background :  emerging antibacterial resistance rates and beta-lactamase producing bacteria recovered from uti is an increasing problem in different regions, limiting therapeutic options. therefore, this survey consider to use the extract and essence of the citrus aurantium (which have a so many rate of planting in iran) and also survey on extract on bacteria whose cause urinary tract infection...

objective: the use of antiretroviral drugs has proven remarkably effective in controlling the progression of human immunodeficiency virus (hiv) disease, but these benefits can be compromised by the development of drug resistance. this study aims to assess the drug resistance profile of the pr gene in highly active antiretroviral therapy (haart)-treated and naïve hiv-1 infected patients. metho...

objectives in this study, we explored a physical method of converting drug-resistant bacteria to drug-sensitive ones. materials and methods this is an in vitro case-control study, performed at the ionizing and non-ionizing radiation protection research center (inirprc), shiraz university of medical sciences (sums), shiraz, iran in 2014. all experiments were carried out using gram-negative bacte...

conclusions these findings underscored the importance of monitoring and developing guidelines for better management of infectious diarrhoea in bangladesh and elsewhere. background diarrhoea is considered as the most widespread illness occurring in bangladesh. in addition, the growing antimicrobial resistance of diarrhoeal pathogens in this developing country hardens physicians to supervise pati...

The observation of a rise in multiple resistance to antibiotics in shigellae by Japanese workers, and their demonstration that this resistance could be transferred to other Enterobacteriaceae by conjugation (Ochiai et al., 1959; Akiba et al., 1960; Watanabe, 1963), opened a new phase both in bacterial genetics and in the study of drug resistance in this group of organisms. Briefly, this type of...

We show here that silver nanoparticles (AgNP) were intrinsically antibacterial, whereas gold nanoparticles (AuNP) were antimicrobial only when ampicillin was bound to their surfaces. Both AuNP and AgNP functionalized with ampicillin were effective broad-spectrum bactericides against Gram-negative and Gram-positive bacteria. Most importantly, when AuNP and AgNP were functionalized with ampicilli...
