Abstract
Non-fermenting gram-negative bacteria are of particular clinical importance in recent years, primarily as an etiologic factor causing nosocomial infections. This group includes Pseudomonas spp., Acinetobacter spp., Moraxella spp., Stenotrophormonas spp., Burkholderia spp. etc. These mi crobes are found chiefly in soil and water; they are also released from the food. Not uncommon colonization (contamination) of medicines, medical equipment, disinfectants by these microorganisms in hospital. Many of them can be found on the mucosa of healthy humans and animals. Most of the non-fermenting gram-negative bacteria are an opportunistic pathogen that causes infections in humans whom the normal clearance mechanisms are impaired; in those who are immunosuppressed. The article presents the sensitivity/resistance of non-fermenting Gram-negative bacteria - Pseudomonas spp. (38 strains) and Acineobacter spp. (23 strains), to widely used antibiotics. It was found that both Pseudomonas and Acineobacter showed a high level of resistance to most of the studied antibiotics, but the fluoroquinolones and carbapenems were sensitive.
