Is Gangrene Contagious?

my husband had second toe amputated gangrene and the wound reopened after stitches removed. It started eating away at the big toe and acts like flesh eating bacteria. Two weeks between office visits are too long with the looks of both toes. I am concerned this type of gangrene can be a contagious transmission. Could I get this deadly bacteria by kissing him?

Hi i do care for your concern.
Most of the time gangrene is caused by tetanus bacteria, it is advisable to get vaccinated against tetanus, though not recommended by WHO.
The main cause for gangrene to occur is due to decreased blood supply that results in growth of non-oxygen requiring bacteria, which causes more damage.
Though bacteria may spread by direct contact, but to develop gangrene other associated condition as mentioned above should be present.
Hence Gangrene as disease is not contagious.
Hope i have answered your question. If you have more doubts feel free to ask.
Thank you.
