Extra Coating Aids Bacterial Spores

NEW YORK, May 7 (UPI) — Bacterial spores that cause botulism, tetanus and anthrax may have an extra coating of protection that help them survive, scientists in New York said.

The new findings offer insight into why bacterial spores are the most resistant organisms, researchers at New York University said in a release Thursday.

Microbiologists studied the spores of Bacillus subtilis, a non-pathogenic bacterium that shares many of the same structural features of spore-forming pathogens, such as botulism, tetanus and anthrax.

An electron microscope confirmed B. subtilis carried an outermost layer, which the researchers named the “spore crust.”

While it has yet to be confirmed, it’s possible the spore crust is a common feature of all spore-forming bacteria, including the harmful pathogens, the microbiologists wrote in a recent issue of the journal Current Biology.

The study was conducted by researchers at New York University’s Center for Genomics and Systems Biology, Loyola University’s Medical Center, and Princeton University’s Department of Molecular Biology.
