arsenic is one of the most dangerous heavy metals in the environment that is harmful for organisms such as human beings. due to this treat economic approach for elimination of arsenic from water and wastewater is necessary. in this research arsenic-resistant bacteria from water and sediments of lake maharloo were isolated and identified then their antibiotic resistance was evaluated. sampling w...

Background and Objective: Antibiotic resistance is the ability of microbes to survive antibiotic exposure with standard doses. Regular updating of antibiotics is one solution to overcome antibiotic resistance. One source with potential new antibiotics is moonmilk from caves because it contains various bacteria proven to have antibacterial activity. The objective of the present study is to explo...

187 commercial checken flocks affected with respiratory diseases were examined for ornithobacterium rhinotracheale isolation. the bacterium was isolated from 105 (56.2%) poultry flocks. drug sensitivity test using standard disk diffusion technique was performed with 19 antibiotics. all the isolates were susceptible to tiamulin and most of them were susceptible to chloramphenicol and linco-spect...

To evaluate the clinical outcomes of pneumococcal pneumonia caused by antibiotic-resistant strains in Asian countries, we performed a prospective observational study of 233 cases of adult pneumococcal pneumonia in 9 Asian countries from January 2000 to June 2001. Among 233 isolates, 128 (55%) were not susceptible to penicillin (25.3% were intermediately susceptible, and 29.6% were resistant). C...

conclusions the present study showed that bla oxa-23-like was the most frequent carbapenemase identified among carbapenem-resistant a. baumannii isolated in tehran hospitals. evaluation of antibiotic resistance genes in a. baumannii, is necessary to control further dissemination of these antibiotic resistant genes. results results showed that 123 of 131 (93.89%) acinetobacter species, possessed...

Antibiotics pose a great public health irony. Their existence and use have made possible the treatment of previously untreatable infections. But simultaneously, rampant antibiotic overuse has promoted the development of antibiotic resistance and new untreatable, highly resistant infections. To address this growing threat, The National Action Plan for Combating Antibiotic-Resistant Bacteria esta...

The tremendous therapeutic advantage afforded by antibiotics is being threatened by the emergence of increasingly resistant strains of microbes. Selective pressure favoring resistant strains arises from misuse and overuse of antimicrobials (notably extended-spectrum cephalosporins), increased numbers of immunocompromised hosts, lapses in infection control, increased use of invasive procedures a...

 The present study was aimed to evaluate the antimicrobial resistance and the presence of antibiotic resistance genes in Vibrios spp. isolated from seafood. A total of 72 isolates of Vibrio in 6 species including V. parahaemolyticus, V. vulnificus, V. alginolyticus, V. harveyi, V. mimicus and V. cholerae were examined. The results revealed that all isolates were expressing multiple antibiotic r...
