BACKGROUND Bacterial colonisation of the respiratory tract is commonly described and usually thought to be of no clinical significance. The aim of this study was to examine the presence and significance of bacteria and viruses in the upper respiratory tract of healthcare workers (HCWs), and association with respiratory symptoms. METHODS A prospective cohort study was conducted in China and 22...
background and objectives: urinary tract infection is one of the most common bacterial infections in the human population, and more frequent infection during pregnancy. with notice to this point that most of urinary tract infections during pregnancy are asymptomatic, they could lead to serious complications such as prematurity, low-birth weight, hypertension, and higher fetal mortality rates if...
Background : Silver nanoparticles have wide applications in medicine and treatment of bacterial infections due to their disinfection properties. Chemical synthesis, biosynthesis and antibacterial properties of silver nanoparticles have been studied previously, but regarding the high costs of chemical synthesis and the increase of antibiotic-resistance phenomenon among bacteria, assessment of ...
Exacerbations of Crohn's disease are not infrequently associated with bacterial gastroenteritis. The recognition of synchronous infections in such patients is vital for the initiation of appropriate antimicrobial therapy. Furthermore, the detection of active bacterial infections may lead the clinician to delay starting biological therapy. We report here a man presenting with an exacerbation of ...
Background: Microbial infections and the resistance to antibacterial drugs are on the rise, and scientists are in search of the safest and most effective approach to overcome them. Medicinal plants are potentially effective against many microorganisms. Therefore, this study was planned to examine the antibacterial properties and cytotoxicity of the extracts of Allium sativum and Myrtus communis...
Serratia species are opportunistic, gram-negative, motile bacteria classified in the large family Enterobacteriaceae and differentiate from Klebsiella spp. with slow fermenting lactose DNAase positive (1,2). One of characteristics that distinguishes them other is to synthesize red pigments, prodigiosins. It can cause nosocomial infections especcialy newborns patients intensive care units. spp.;...
coagulase-positive and coagulase negative, methicillin-resistant staphylococci are major causes of serious nosocomial infections and it is very important to have a reliable test to detect these bacteria. a multiplex polymerase chain reaction (mpcr) was used on 100 clinical samples for simultaneous amplification of the universal bacterial, mec-a encoding the penicillin binding protein 2a, which ...
conclusions this results of the study show that the most contamination in nicus is from gram-negative bacteria and ciprofloxacin is the most effective antibiotic for treatment. thus, the control of infections in nicus in hospitals is very important. results during the seven-month study on 105 samples, including 85 (81%) urine samples and 20 (19%) blood samples, 81 samples (77.1%) were gram-nega...
The emergence and spread of antimicrobial-resistant bacterial, viral, and fungal pathogens for which diminishing treatment options are available is of major global concern. New viral respiratory tract infections with epidemic potential, such as severe acute respiratory syndrome, swine-origin influenza A H1N1, and Middle East respiratory syndrome coronavirus infection, require development of new...
