Species: P. aeruginosa

3. Pseudomonas aeruginosa is
a Gram-negative, aerobic,
rod-shaped bacterium, 0.5 to
0.6 by 1.5 microns, occurring
singly, in pairs and short
chains. motile possessing one
to three polar flagella.

4. It has been identified as
an opportunistic
pathogen of both
humans and plants, as it
infects the airway,
urinary tract, burns, and
wounds, and also causes
other blood infections.

5. Furthermore, it has been known for its
characteristic water-soluble pigment as
pyocyanin (blue-green), pyoverdine (yellow-
green fluorescent), and pyorubin (red-brown,
produced by a small proportion of strains), also
for high ability to resist antibiotics.

6. As it is almost exist in every very, P.aeruginosa is
cultured in different types of media and incubated
with a temperature of 37°c or 42°c to good growth.

7. The anti-microbial bandage
Scientists in Switzerland have developed an infection-
fighting bandage that could help prevent burn victims
from succumbing to the bacteria breeding in their
wound dressings

8. During convalescence, burn patients might be missing
skin on parts of their bodies and wear bandages to treat
their injuries. While these dressings may help heal burn
wounds, like other cloth-based materials, they’re also
ideal breeding grounds for bacteria.
It’s a significant problem, since, according to the
researchers, death from post-burn infections is more
common than fatalities from the burns alone. This is
especially so with Pseudomonas aeruginosa, the main
cause of bacterial infection among patients with serious
burns.

9. This is where the new biological bandage comes in.
Designed to accelerate the scarring process, the
dressing aims to ultimately keep bacteria from
multiplying, which could help head off infections
before they take hold.
What the researchers have done now is combine the
bandage with molecules called dendrimers. When the
gauze is applied to a bacteria-infected site on a patient’s
skin, some of the dendrimers migrate to the skin and
destroy the microbes in the vicinity, while others stay
behind as a kind of rear guard.
