Introduction: Bacterial pneumonia occurs in most hospitalized patients where is the important cause of morbidity and mortality. To reduce the mortality rate, we aimed to isolate the bacterial agents of pneumonia and determine the antibacterial resistance. Methods: In this descriptive study, 330 hospitalized patients inffered from bacterial pneumonia were studied to identify the bacterial ag...
Objective(s): Phage therapy is a potential alternative treatment for infections caused by Acinetobacter baumannii, a significant nosocomial pathogen, which has evolved resistance to almost all conventional antimicrobial drugs in poor hygiene and conflicts areas such as Iraq. Materials and Methods: Bacteriophages were isolated to highly resistant isolates of A. baumannii to form therapeutic phag...
abstract biofilm is a complex community of microorganisms residing within a polysaccharide and/or protein matrix. biofilm can be produced by microorganisms such as bacteria and fungi. both gram positive and gram negative bacteria have this ability. resistance of biofilm to antimicrobial agents is becoming a global issue. bacterial biofilms are important in various aspects such as chronic human ...
Extended laboratory culture and antimicrobial susceptibility testing timelines hinder rapid species identification and susceptibility profiling of bacterial pathogens associated with bovine respiratory disease, the most prevalent cause of cattle mortality in the United States. Whole-genome sequencing offers a culture-independent alternative to current bacterial identification methods, but requi...
Antimicrobial peptides, or AMPs, play a significant role in many environments as a tool to remove competing organisms. In response, many bacteria have evolved mechanisms to resist these peptides and prevent AMP-mediated killing. The development of AMP resistance mechanisms is driven by direct competition between bacterial species, as well as host and pathogen interactions. Akin to the number of...
Bacterial strains resistant to various antibiotic drugs are frequently encountered in clinical infections, and the rapid identification of drug-resistant strains is highly essential for clinical treatment. We developed a locked nucleic acid (LNA)-based quantitative real-time PCR (LNA-qPCR) method for the rapid detection of 13 antibiotic resistance genes and successfully used it to distinguish d...
conclusions mobiles contamination with different pathogens is extremely common among our health care staffs compared with other societies, and resistance of these isolates to various antibiotics is also detectable. thus, quick assessment of this issue to prevent the spread of these infectious agents is critical for the authorities in our health care systems. results in total, 99.2% of mobile ph...
Antimicrobial susceptibility testing is essential for guiding the treatment of many types of bacterial infections, especially in the current context of rising rates of antibiotic resistance. The most commonly employed methods rely on the detection of phenotypic resistance by measuring bacterial growth in the presence of the antibiotic being tested. Although these methods are highly sensitive fo...
