bacterias
Single-celled microbes
Bacterias is a nonstandard plural of bacteria.
The word bacteria is already plural—the singular is bacterium—so adding -s is technically redundant.
Nevertheless, bacterias appears in casual speech and informal writing: The bacterias in your gut help with digestion.
In scientific and formal contexts, bacteria remains the accepted plural.
