five common tetracycline resistance genes tet(a), tet(b), tet(m), tet(o) and tet(s) were studied by polymerase chain reaction in 100 bacteria isolated from iranian fish farms. in the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. nine isolates out of 46 aeromonas spp. contained either tet(a/m/s) resistant genes as follows: tet(a) in a. ...
The presence of pan-resistant bacteria worldwide possesses a threat to global health. It is difficult to evaluate the extent of carriage of resistant bacteria in the population. Sewage sampling is a possible way to monitor populations. We evaluated the presence of pan-resistant bacteria in Israeli sewage collected from all over Israel, by modifying the pour plate method for heterotrophic plate ...
The emergence of drug-resistant strains of bacteria is an increasing threat to society, especially in hospital settings. Many antibiotics that were formerly effective in combating bacterial infections in hospital patients are no longer effective because of the evolution of resistant strains, which compromises medical care worldwide. In this article, we formulate a two-level population model to ...
background and objective: diabetes mellitus is one of the main problems in health systems in the world. diabetic foot infections (dfi) is one of the main complications and the most cause of non-traumatic lower limb amputation .this study aimed to determine the prevalence of bacteria involved in dfi and their antibiotic resistance in patients with dfi diagnosis. patients and methods: this desc...
Resistance to desiccation was utilized in the selection of highly radiation-resistant asporogenous bacteria from non-irradiated sources. A bacterial suspension in phosphate buffer was dried in a thin film at 25 degrees C and 33% relative humidity. Storage under these conditions for 15 days or more reduced the number of radiation-sensitive bacteria. Further selection for radiation-resistant bact...
