Influenza viral infection is well-known to predispose to subsequent bacterial superinfection in the lung but the mechanisms have remained poorly defined. We have established a murine model of heterologous infections by an H1N1 influenza virus and Staphylococcus aureus. We found that indeed prior influenza infection markedly increased the susceptibility of mice to secondary S. aureus superinfect...
OBJECTIVE To investigate the antibacterial activity of henna (Lawsonia inermis Linn) obtained from different regions of Oman against a wide array of micro-organisms. METHODS Fresh henna samples were obtained from different regions of Oman as leaves and seeds. 100 g fresh and dry leaves and 50 g of fresh and dry seeds were separately soaked in 500 mL of ethanol for three days, respectively, wi...
Background and objectives: Metallobeta-lactamase production is one of the most important mechanisms of antibiotic resistance. The aim of the present study was to evaluate the antibacterial activity of Stachys lavandulifolia and Quercus brantii on the IMP-type metallo-beta-lactamase-producing Pseudomonas aeruginosa. Methods: This study...
Background: Listeriosis can be fatal for vulnerable groups of society. The disease has been widespread in recent years due to the large consumption of dairy and meat products. There is little information about the susceptibility of antibiotics and the pattern of Listeria monostigenesis gene resistance in Iranian society. Accordingly, the present study was conducted to investigate the antibiotic...
Carbon-based nanomaterials have a great potential as novel antibacterial agents; however, their interactions with bacteria are not fully understood. This study demonstrates that the antibacterial activity of graphene oxide (GO) depends on the physiological state of cells for both Gram-negative and -positive bacteria. GO susceptibility of bacteria is the highest in the exponential growth phase, ...
Background: Ventilator Associated Pneumonia (VAP) is one of the serious complications of ventilator support occurring in ICUs. The aim of this study was to determine the susceptibility pattern of Acinetobacter baumannii (A. baumannii) isolated from patients with VAP by two methods: disk diffusion and E. test. Methods: This descriptive-cross sectional study was conducted in the four ICUs of Ras...
Determining the susceptibility of pathogens to antibacterial substances is one key steps in bacteriological diagnostics that affects success both therapeutic therapy and appropriate selection cosmetic products. Antibiotic chemotherapeutic sensitivity tests determine ability an antimicrobial agent inhibit growth a microorganism vitro.
