organisms in or on an object or substance. Disinfectants and antiseptics do not sterilize since many types of organisms and spores are not killed. Disinfectants are described as antimicrobial agents that are used on inanimate objects such as an instrument or structural surfaces. The term antiseptic is usually applied to antimicrobial agents that are used on living tissue such as skin and throat mucosa. A disinfectant must be capable of killing pathogens while it is in contact with them‚ so that they

Meanwhile‚ effective microbial control of urinary tract infection depends on the excretion and sustenance of therapeutic concentration of antimicrobial agents in urine. The excretion rate data revealed that the herbs significantly reduced the elimination of norfloxacin‚ with the effect of tea being higher than that of GKS. This interaction may not be attributed to partition coefficient because

Antimicrobial properties of essential oils (EOs) reveal that Gram-positive bacteria are more vulnerable than Gram-negative bacteria. A number of EO components have been identified as effective antibacterials‚ e.g. carvacrol‚ thymol‚ eugenol‚ cinnamaldehyde and

Antibiotic resistance In recent years a challenge to the effective treatment of an ever-increasing range of infections caused by microbes is antimicrobial resistance (AMR). AMR results in reduced effectiveness of antibiotics‚ making the treatment of patients very difficult and sometimes impossible. The impact on especially susceptible patients is most evident‚ resulting in prolonged illness and increased mortality. The total problem caused by AMR on medical field in general and healthcare sector
