"aseptic" poems
Preventing contamination,
A constant challenge in cell culture.
Contamination not only affects,
The culture in question and,
Costs time and money,
But also endangers the reproducibility of results.
No cell culture problem,
Is as universal as that of culture loss
Due to contamination.
Generally, contamination may be separated,
Into categories of microbial,
And eukaryotic contamination.
Examples of microbial contamination include:
Bacteria (including Mycoplasma),
Fungi and yeast;
Eukaryotic contamination includes:
Cross-contamination with other cell lines.
Bacteria, yeast and fungi,
The three more common types of contamination,
But luckily these forms are often detectable,
Under the microscope and,
By visual cues,
Like colour or turbidity changes in the medium.
Mycoplasma is a small genus of bacteria,
That lack a cell wall and for this reason,
They remain unaffected by common antibiotics.
They are also difficult to detect,
With standard microscopes,
Due to their size, about 0.1 μm in diameter,
And the fact that they often attach to host cells.
To prevent contamination,
Use 70% ethanol for disinfecting,
Equipment & surfaces,
Related to cell culture.
Sterile filter the media first,
Before bringing to the lab.
Fetal Bovine Serum,
A potential source of contamination,
Contains mycoplasma.
Filter it at 0.1 μm, or,
Gamma irradiate it.
Aseptic technique,
Necessary.
The laboratory workers be the last,
But not the least source of contamination.
Teach them the ideal laboratory practices,
To ensure asepticity in a laboratory.

Brought forth from a darkness so secure, baby boy relentless in the pursuit of education gazed upon the egg shell walls and sterile environment.
Breathing as if it were natural.
A construction of steel and concrete was the new cocoon , the window was an eye to a neoteric world. Bright white lights shone from within and a dull foreboding cloud loomed beyond the glass for the child to appreciate.
Mother exhausted collapsed sighing. She is the antidote to all that is evil, she is the mother to the world. A usually stick-thin figure now distended but leisurely relaxing.
Nursing her son as if it were natural.
Swooning nurses swaddle infants, the original factory workers. Substantial days grafting, workhorses prancing throughout aseptic halls.
The heroines of our world.
A tribe appears from dust clouds, over the dunes, panting, half-alive. Heavenly Ethiope arriving in time for the world to begin. Tumescent in her ecclesiastic luminescence bearing a King destined to travel great distances primed for expulsion from the cimmerian safety of the womb.
The seas of the earth accumulate before the small band of tall-standing creatures of exquisite anthropomorphism. Creatures from across the great unexplored continent at the centre of our world gathered in frenzied crowds. The Elephants marched in earth shattering herds, the lions of the Savannah put aside their differences and sat amongst the wild dogs of Ethiopia and the grévy's zebra, the dibatag stood and eagerly waited. Shrews, mice, gazelle, otters, cheetahs and giraffes all surrounded the tribe. Taking a silent vow and allowing stewardship to be passed along to a new generation.
Every mother is the mother of the earth. Her earth, the personal concept of earth that only she may understand.
Both children are connected by the planet they learn to walk upon. Connected by a thousand generations but connected nonetheless. They are one and the same. Each bought into a world in which they have no knowledge, each merely a slate eager to be scrawled upon by the elders of this fine rock.

Long gone are the days of ******
No more people say, "Alle Rufen ******
Germany is now aseptic and really safe,
Na'zi germs are no longer there.

In the morgue, the aseptic light
Was flickering upon it;
The livid, bruised, black and blue
Lying body of Love.
-Honey, It's dead, you see!
-Yes, sweetheart, but how did we
Come to this?
-Pass me the lancet and
Then we'll see.
A sharp cut was made on
The right temporal lobe of the brain;
The synaptic membranes were
Damaged, the reciprocal nerve-racking
Jealousy had made the brain collapse.
A big incision was made upon
The ribs: into the lungs no more
The vital breath of Love, only water
And mud were clogging the alveoli.
Love had drowned in the sea of adultery.
The last deep cut was made upon
The heart: the still valves and
Ventricles hadn't pumped
Blood and passion for long.
So, there's nothing else to do,
My dead love!

upon coming to the exit and birth, beginning, origin of the supermarket, I had the vision I was pushing my own body out of the morgue/into the abyss.
sleek, ultra-modern, aseptic carrion floor, processed through checkout, aisles, background fuzz, and the pointless chatter of deciding upon this or that alienated labour product.
the worthless time, the bare destitution, the surging eyes fixed across a nothingness that reduced both you and i to economic ex--
a holy verification of existence together in this ******* astronomically ******* up world.
blood at my index, slit along the serrated edge of a tin, metal scrap, upon a mountain of flesh; empire, bread and sons.
mass, ***** incarceration, brand loyalty, ethical spending, assimilation; all wallets bleed the same.
my race, my class, my gender, my age; DIY elevator pitch.
there.s nothing left.
there.s no.thing lft.
there.s n.thing .ft.
th.re.s g.f.
h.re.
e.
fine thread through the arched belly of a bleached whale, blood mixed with the grease, and salt, and death.
