Sporing bacteria are the cause of a number of serious diseases in humans. Among diseases caused by anaerobic sporing bacteria are botulism (Clostridium botulinum), gas gangrene (Clostridium perfringens), tetanus (Clostridium tetani) and acute food poisoning (Clostridium perfringens again). Anthrax results from the aerobic sporing bacteria Bacillus anthracis.
In 1995, Raul Cano and Monica Borucki, of California Polytechnic State University in San Luis Obispo, reported having recovered and reanimated bacterial spores from the digestive tracts of bees that had been entombed in amber for between 25 and 40 million years. Similar remarkable claims have been made for the temperature resistance of spores. About one in 100,000 have been shown to survive brief exposure to the 3,000°C flame of a rocket exhaust, while others have emerged unscathed from a bath in liquid helium at -269°C. These findings are cited as evidence by proponents of panspermia that spores might be able to travel for millions of years across interstellar distances yet remain viable.
