Basic Shapes

most bacteria come in one of three basic shapes:  coccus, bacillus and spiral.

Coccus

Based on planes of division, the coccus shape can appear in several distinct arrangements:
diplococcus, streptococcus, tetrad, sarcina, and staphylococcus.

Bacillus

The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.

Spiral

The spiral shape can appear in several forms: vibrio, spirillum, and spirochete.

Size

The metric unit micrometer (1/1,000,000 or 10-6 of a meter) is used to measure bacterial size.

We will revisit bacterial sizes when looking at BioProtect’s revolutionary antimicrobial technology. Using a mechanical barrier, BioProtect’s spikes pierce and rupture the cell membrane of each microbe. This prevents the colonization and growth of these microbes on a protected substrate, but also prevents the creation of  antibiotic resistant Superbugs.

To ensure a substrate is adequately disinfected prior to the application of the antimicrobial, we recommend disinfection with our EPA registered hospital grade SmartTouch disinfectant. It is also NSF registered as a no-rinse food contact sanitizer, kills mold and mildew, and eliminates allergens and odors.
