archaea/m.smithii – old/new

Methanobrevibacter smithii, AKA M. smithii, member of Archaea domain, I don’t know of you before this. I feel bad considering you are descendants of the oldest life in existence.

Archaea derives from the Greek word achaios, meaning ancient or primitive.

M. smithii look how beautiful you are…

The single-celled microorganism Methanobrevibacter smithii,  the most abundant  archaeon in the human gut, aids in digestion of complex sugars. These microbes are a hydrogenotroph (consumes hydrogen) and a methanogen (produces methane). Yes, they are manufacturers of gas!

Methano refers to its connection with methane, and brevibacter means short rod. There appears to be an association between gas production and body weight. M. Smithii may influence weight gain and loss (anorexia) as well as constipation.

These microorganisms are prokaryotes having no cell nucleus (or any other membrane-bound organelle). Archaea, in general, are unique in that they have a distinct biochemistry.

About archaea and life…
They’ve been around for about 4 billion years! They’re resilient, truly thriving between order and chaos, proving life creative – even in time of crisis.

white becoming white

Candida albicans, member of the Saccharomycetaceae (yeast) family as well as the human microbial community, I especially enjoy painting you fungus. I wasn’t planning on it, but maybe I’ll draw another member of your fungi kingdom.


The word Candida comes from the Latin candidus, meaning white. Albicans derives from the Latin word albicō, meaning becoming white. White becoming white.

Man, are we loaded with bugs! I never gave this stuff a thought…by stuff I mean the variety of microorganisms, including candida, holding microscopic space in the human body.

This fungus is most commonly found in the gastrointestinal tract and mouth (in at least 80% of the worldwide population). In some circles Candida aids in food digestion and absorption, while in other circles (the out of control circles?) it’s known as an opportunistic pathogen.

The fungus (yeast) is naturally  found in the human body, primarily in the intestine, colon and mouth. Out of control, it can attack skin and mucous membranes. It can also travel through  the blood stream and affect kidneys, heart, lungs, throat and heart-valves. (Is this what it means to be metabolically flexible?)

cellular structure.

C. albicans is an eukaryotic organism. It’s structure includes a cell wall (which seems an important aspect to this microorganism), nucleus, ribosomes and mitochondria. I don’t know what it means when I read hyphae sense reproductive units from a distance and grow towards them but it makes me think of an electric pull.

I appreciate the lace-like quality of the organic form. The long branches, called hyphae (web) with their circular budded tip, appeal to me. This subject-matter is visually elegant and playful. Candida itself, complicated.

Here is what I wonder:
Candida albicans are commensal. We eat at the same table? I take this to mean they consume what the human host consumes. Yes? Or do they eat what the host discards?  Mutually beneficial?
Is C. albicans overgrowth always seen as an attack on the body? Can the out of control set up be a warning sign of another imbalance (other microbes) in the human body?

twisted and seedy bacteria – you are streptococci

I work H. Pylori bacteria a few weeks ago so why do I feel the need to mess with Streptococcus? Bacteria is bacteria – or is it? Maybe it’s all about location…

Strepto from Ancient Greek: streptós, means easily twisted, pliant. Coccus from Modern Latin: coccus, from Ancient Greek: kókkos, translates to grain, seed, berry.

My painting goes through too many mutations for several reasons including that at times I don’t care for the look and feel of the surface, the heavy line work is not a preference and again, I discover filters.

Streptococci (plural) forms in pairs or chains. My compositions focus on their spherical quality, otherwise you’d see connecting chain-like or bead-like forms moving across the picture plane.

I work with smooth mylar to play with the translucent quality and glossy surface. What am I thinking to lay in a gesso black ground? Everything goes opaque, contrast is high and I lose a natural lightness. I rework and overwork.

Frustrated, it feels right to cut the bacteria out and seal it into a petri-dish. I enjoy holding it (with my cotton gloves).

A few weeks ago a friend comments about streptococcus bacteria and its relationship to heart problems (aortic valve). It leaves an impression. I know then I’ll draw the bacteria.

Streptococci can live in the mouth, nose, throat, upper respiratory tract, intestine, genital tract, and on the skin. Particular strains can cause pink eye, meningitis, endocarditis and necrotizing fasciitis. Its trouble causing span feels much too broad, from the not so serious to the deadly serious. It surprises me to learn its nonmotile. It doesn’t move?! (Unlike H. Pylori with its flagella.)

I do move…
Yesterday, I don’t like these studies. Today, is a brand new day and I like them after all. Next: Fungi.


PS: I can’t write very much about the microorganisms I study. While I understand some things in general, I don’t understand things in particular. It’s a whole new (microscopic) world.

I look at microbiota – in hope of gaining insight into the human microbiome.  I hear microbial cells, in and on our body, outnumber our human cells 10-1 (statistics seem to vary – what do I know).  But what does this all mean in terms of our genes? What rules – the human or the microbial?

The most valuable thing that happens as I continue to work is I make connections to things I understand or thought I understood.  Let’s see how it works itself out of me.

In the meantime, I love the tiny stuff I’m drawing. I just wish I’d gone bigger with the microorganisms. I tell my drawing students regularly – it’s easier to work large than it is to work small. Right now I feel like the latter is the only thing I know for certain (but this too can change).
