Gram Negative Bacteria
The integration of foreign DNA into the genome of Gram-negative bacteria, such as Acinetobacter sp. BD413, occurs through a process known as natural transformation, which is a significant gene transfer mechanism in prokaryotes.

Natural transformation Constitutes a major gene transfer
mechanism in the prokaryotes Researchers found the integration of foreign DNA into the genome of the Gram-negative Acinetobacter sp. BD413 during transformation. The active uptake of cellular DNA The Mechanism & Function of Natural Competence Gram Negative bacteria take up DNA
in two stages : DNA translocation (across the
inner membrane) DNA uptake (across the outer membrane) Gram Negative Bacteria Research NIAID-funded researchers are exploring these related to
Gram negative bacteria and the diseases they cause. Researchers are unraveling the molecular
mechanisms of drug resistance to identify novel strategies to
combat these pathogens New drugs to combat Gram negative bacteria
infections are needed. Prevention Vaccines are not available for most healthcare-
associated caused by Gram negative bacteria. To reduce it, hand washing and having healthcare
workers wear gloves Many infections occur through
cross contamination between people. Characteristics Thin peptidoglycan High Lypopolysaccharides Appear pinkish or red Treatment For example, the unique nature
of their cell wall makes them resistant
to several antibiotics Can be difficult because of several
unique features of this bacteria Transmission This can lead to pneumonia and such infections of the : urinary tract joints bones bloodstream Bacteria enter the body through : wounds ventilators urinary
