Abstract We present a case of bacterial endocarditis with both methicillin-sensitive and methicillin-resistant Staphylococcus aureus , which based on typing, originated from two distinct clones. Such may be misinterpreted by microbiology lab automation to monoclonal multi-drug resistant while simple techniques will instantly reveal clonality.

The occurrence and spread of multi-drug resistant bacteria is a pressing public health problem. The emergence of bacterial resistance to antibiotics is common in areas where antibiotics are heavily used, and antibiotic-resistant bacteria also increasingly occur in aquatic environments. The purpose of the present study was to evaluate the impact of the wastewater treatment process on the prevale...

the nosocomial infections, caused by multi-drug resistant bacteria, are the most important cause of mortality throughout the world. one important mechanism against beta-lactam antibiotics is the production of beta-lactamases. enterobacteriaceae and non-fermentative bacteria, like pseudomonas aeruginosa and acinetobacter baumannnii may produce these enzymes. currently, there is no vaccine to pre...

Results Altogether 28.9% of the residents had wheelchair disability or were bedridden, 10.6% disoriented in time and/or space, 49,5% had urinary incontinence and 35,3% fecal incontinence. Prevalence of MDRO was found to be 12.4%. The most common pathogens were MRSA, which consisted 43,2% of all S. aureus isolates (n=94) and ESBL(+) rods, which reached 13,9% out of 165 Enterobacteriaceae isolate...

conclusions the present study reports on a high rate of multi-drug resistance, the predominance of the frequency of class 1 integron, and the emergence of spa type t790 among iranian staphylococcus aureus strains. the results revealed that the dissemination of multi-drug resistance among staphylococcus aureus isolates may be associated with the presence of integrons. therefore, continuous surve...
