cockroaches were collected from hospitals, houses and poultry sheds in various parts of isfahan (iran) and identified to species. in total, seven species of cockroaches in seven genera were identified: blatta lateralis, polyphaga aegyptiaca, arenivaga roseni and parcoblatta spp. three species periplaneta americana, blattella germanica and supella longipalpa (blattidae and blattellidae) were mor...

background: multi drug resistant (mdr) pseudomonas and acinetobacter species are defined as resistant to at least three classes of antibiotics. most studies have demonstrated that mdr gram negative infections convey increased mortality and morbidity. case: an 11-year –old girl was admitted to pediatric burns unit with burn injury of approximately 68% total body surface area (tbsa). discussion: ...

BACKGROUND Multi-drug resistant bacteria are increasing and remain a major public health challenge worldwide. In order to understand the potential role of medical students as a reservoir for circulating pathogenic bacteria and their transmission, we analysed the nasal colonisation among 86 clinically exposed medical students of the Medical University of Vienna, which is integrated into General ...

6 The large reservoir of antibiotic resistant bacteria in raw and treated water supplies is a matter of public health concern. Currently, the National Antimicrobial Resistance Monitoring Systems, a collaborative effort of the Centers for Disease Control, the US Department of Agriculture, and the US Food and Drug Administration, does not monitor antimicrobial resistance in surface waters. Given ...

background and objective: uttarakhand region is less explored, but possess a great biodiversity. this diversity can be explored for isolation and characterization of new actinomycetes strains for seeking antimicrobial molecules. it can therefore be predicted that novel bioactive metabolite producing actinomycetes can be discovered to combat multidrug resistant bacterial pathogens. materials and...

Epidemics of drug-resistant bacteria emerge worldwide, even as resistant strains frequently have reduced fitness compared to their drug-susceptible counterparts . Data from model systems suggest that the fitness cost of antimicrobial resistance can be reduced by compensatory mutations2; however, there is limited evidence that compensatory evolution has any significant role in the success of dru...

Two silver sulfadiazine-resistant isolates of Enterobacter cloacae obtained in a burns unit where the drug was in use were studied. These strains were resistant to elevated levels of the drug, and they were cross-resistant to silver benzoate, but not to silver nitrate. Growth of the strains in nutritionally poor defined media sensitized them to the inhibitory action of the drug. Exposure of the...

Multidrug drug resistant bacteria are becoming increasingly problematic particularly in the under developed countries of the world. The most important microorganisms that have seen a geometric rise in numbers are Methicillin resistant Staphylococcus aureus, Vancomycin resistant Enterococcus faecium, Penicillin resistant Streptococcus pneumonia and multiple drug resistant tubercule bacteria to n...

BACKGROUND Previous researches about necrotic pancreatic tissue infections are numerous, but the study on systemic infection related to the severe acute pancreatitis (SAP) treatment period is limited. This study aimed to investigate the distribution and drug resistance of pathogenic bacteria in patients who had hepatobiliary surgery for SAP during the past three years. METHODS A retrospective...
