Incidence of Acinetobacter spp. and other gram-negative, oxidase-negative bacteria in fresh and spoiled ground beef

Cell Envelope Structure and Functions in Gram-negative Bacteria

Comparative activities of tigecycline and other tetracyclines against nonfermenting Gram-negative bacilli, excluding Acinetobacter spp.

Tigecycline, a glycylcycline, is a semisynthetic derivative of minocycline with a broad spectrum of activity against aerobic and anaerobic bacteria (2, 12, 16). In the literature there are several publications concerning tigecycline activity, most of them related to Acinetobacter baumannii and Stenotrophomonas maltophilia isolates (1, 5, 8, 10, 11, 14); however, its activity against other speci...

Synthesis and Characterization of Novel Antibacterial PDDA/Honey Nanofiber Against Gram-Positive and Gram-Negative Bacteria

Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...

Antibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan

Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...

Genetic tools for pseudomonads, rhizobia, and other gram-negative bacteria.

Gram-negative bacteria are extraordinarily diverse microorganisms that present a wide variety of characteristics worthy of genetic investigation. For historical reasons, the application of recombinant DNA technology to gram-negative bacteria in general has always lagged behind that of E. coli and its close relatives. However, the past 10 years have seen dramatic advances in the development of n...
