Bacteria

 

Coccu BacteriaCocci (plural of coccus) bacteria are found in this circular smear. These cocci are too small to see below 400x. Although 1000x oil magnification is done, individual cocci are still barely visible. This image at left is a a collage of several images combined to cover the entire smear.

Colony of Cocci

This colony of coccus looks like fiber strands. These cocci are too small to be seen at 400x. 1000x oil is needed to get any sort of understanding of the individuals, but this image clearly shows groups in string like structures. These strings look like extremely tiny fish roe.

Streptococcus

Admitedly, I'm a new to the -ccus versus -cci suffix business. Even though I have heard the -ccus ending used more often, I'm personally tempted to use -ccii for everything.

Streptococci are found in abundance. Individual balls are lined up like a chain. Even at 1000x with oil, it is hard to see clear details of the cocci.

Bacillus

Even though this slide is labled coccus, some bacilli seem to have snuck in. Interestingly, these hot-dog shaped versions are identical in color to the cocci. I don't know if this is due to stain, but it gives the ludicrous impression that the cocci will grow up to be bacilli.
