CELLS alive! Library: Contents of Volume 2

Motility of E. coli

2.1 Motility of E. coli

Common intestinal bacteria in real time. They swim by means of hair-like flagellae that cannot be seen at this magnification. Color is added at time of recording by computer.

Growth of E. coli speed x440

2.2 Growth of E. coli speed x440

These bacteria were grown on the microscope stage and are shown at 440 times real speed. Each bacterium can divide every 20-30 minutes.

Motility of Salmonella enteritidis

2.3 Motility of Salmonella enteritidis

Another rod-shaped bacteria, Salmonella enteritidis can be found in raw eggs and has become the number one cause of food-poisoning outbreaks in the US.

Growth of Salmonella enteritidis Speed x 360

2.4 Growth of Salmonella enteritidis Speed x 360

Same bacteria shown in time-lapse at 360 times real speed.

Neutrophil oxidative activity shown with NBT.

2.5 Neutrophil oxidative activity shown with NBT.

Same white blood cell as #10 on Vol 1, but colorized to enhance oxidative activity.

Helicobacter pylori

2.6 Helicobacter pylori

A bacterium just discovered in past few years and shown to be the cause of most stomach ulcers. Has led to treatment of ulcers with antibiotics rather than just antacids.


2.7 Artemia

AKA "Sea Monkeys" or Brine Shrimp. Artemia eggs can remain viable for years without water. Ordered from the back pages of magazines, and rehydrated with salt water for just a few hours, the embryos begin hatching as nauplius larvae. See them hatch, and see the nauplii swim, bob and dart. In this tape, you can also follow them to the adult stage (2-3 weeks).

Human Sperm

2.8 Human Sperm

Sperm are some of the most active cells in the body, their motility responsible for getting them to the site of an ovum for fertilization. Both black and white and colorized clips show their rapid whip-like movement, as well as their morphology: head with enclosed DNA, midpiece, and tail (flagellum).
