b a ckground: cockroaches are among the medically important pests found within the human habitations that cause serious public health problems. they may harbor a number of pathogenic bacteria on the external surface with anti- biotic resistance. hence, they are regarded as major microbial vectors. this study investigates the prevalence and antibiotic resistance of gram-negative pathogenic bacte...

objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

background and objectives: non-fementer gram-negative bacilli (nfgb) are ubiquitous pathogen that has emerged as a major cause of health care associated infections. the aim of this study was to determine the prevalence and antimicrobial susceptibility of   nfgb in an iranian hospital. materials and methods: fromjuly 2005 to november 2006 a total of 257 strains of nfgb including 109 (42.41%) str...

conclusions our results showed the rate of effects of different risk factors on imipenem resistance. regarding the studied risk factors, appropriate programs must be set in place to control and prevent imipenem resistance in gram-negative bacteria. results of the 374 isolated, 134 were imipenem resistant, and 240 were sensitive to imipenem. the resistance rate was more common in males and in pa...

bacteremia is an important infectious disease which may lead to death. common bacteria and pattern of antibiotic resistance in different communities are different and understanding these differences is important. in the present study, relative frequency and pattern of drug resistance have been examined in bacteria isolated from blood cultures in razi hospital laboratory. the method of the study...

agricultural and specifically industrial activities have led to a substantial release of toxic heavy metals in the environment which can constitute a major hazard for ecosystem and human health. biosorption of heavy metals is one of the most effective technologies involved in the removal of toxic metals from contamination sites that has used in the last decade. population and microbial activity...

Bacterial infections may cause disease and death. Infants and children are often subject to bacterial infections. Antimicrobials kill bacteria protecting the infected patients andreducing the risk of morbidity and mortality caused by bacteria. The antibiotics may lose their antibacterial activity when they become resistant to a bacteria. The resistance to different antibiotics in a bacteria is ...

background the rapid emergence of antibiotic resistance, especially broad-spectrum antibiotics, resulted in the avid use of new potent antibiotics. ceftriaxone and ceftazidime, two third-generation cephalosporin, are usually used to manage complicated and uncomplicated infections. the use of cefepime in resistant infections is increasing gradually, which put this potent antibiotic at risk of re...
