PURPOSE To study the qualitative and quantitative methods for the investigation of biofilm formation and to examine the correlation between biofilm and antibiotic resistance among the clinical isolates of Acinetobacter baumannii . We also verified the association between biofilm and presence of extended spectrum beta-lactamases, particularly, bla PER-1 . METHODS A total of 55 isolates were su...

Cloacal and pharyngeal swabs from 100 tree-nesting Double-crested cormorant (DCC) chicks were examined by culture for commensal and potentially pathogenic bacteria. No Salmonella or Erysipelothrix were isolated from the cloacal swabs. Twenty-two cloacal swabs were positive for Campylobacter, of which 14 were C. jejuni, C. coli, and 1 C. lari. None belonged to common serotypes isolated from huma...

tuberculosis is an infectious disease caused by mycobacterium tuberculosis and is the primary cause of mortality in the world. m. tuberculosis strains are important intracellular pathogens causing infection in oxygen-rich macrophages in the lungs. the emergence of aids, declined socioeconomic standards and a lessened emphasis on tb control programs have contributed to the disease resurgence. re...

background: nowadays, nosocomial infection with multidrug-resistant acinetobacter is an important problem in the world, which is facing wide spectrum antibiotics and hence has become resistant. m aterials and methods: in this study, positive cultures of acinetobacter from one hundred clinical samples in seven hospitals from tehran during 2012-2013 were collected for checking antibiotic suscepti...

background: due (drug utilization evaluation) studies can help identify and correct problems associated with irrational use of drugs. considering lack of data regarding how rational vancomycin is being used, we evaluated this due study in a referral infectious center to evaluate compliance with guidelines in terms of rational use of this valuable antibiotic. methods: this retrospective study wa...

Monitoring trends in antimicrobial drug-resistant Neisseria gonorrhoeae is a critical public health and global health security activity because the number of antimicrobial drugs available to treat gonorrhea effectively is rapidly diminishing. Current global surveillance methods for antimicrobial drug-resistant N. gonorrhoeae have many limitations, especially in countries with the greatest burde...

1614 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 12, No. 10, October 2006 multidrug-resistant gram-negative pathogens, and enhanced measures are needed to prevent spread of these organisms. A greater understanding of the modes of spread and acquisition of these organisms is essential for effective control of this problem. We have reported just 1 case of infection with an almost comple...

Antimicrobial drug resistance (AMR) is widely recognized as a global public health threat because it endangers the effectiveness of treatment of infectious diseases. In 2001 WHO issued the Global Strategy for Containment of Antimicrobial Resistance, but it has proved difficult to translate the recommendations of the Global Strategy into effective public health actions. The purpose of the Antimi...

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most threatening pathogens due to its multi-drug resistance (MDR) and strong biofilm-forming capacity. Here, we described the screening of a novel chimeolysin (ClyF) that was active against planktonic and biofilm MRSA. Biochemical tests showed that ClyF was active against all S. aureus clinical isolates tested under planktonic and...
