Sue's done an authoritative exposition on bactericides in her last post. She's certainly got a lot of practical experience and knowledge of the subject. I'll just mention something else about bacteria that I think she'll agree with. People generally fear most the well-known dangerous pathogens such as botulism, cholera, typhoid. Those pathogens can be avoided or controlled by good hygiene and food safety measures. But if we return to a world without antibiotics there will be another, greater danger. Other bacteria are everywhere in our environment and most of the time they do us no harm and may be beneficial. But if they get into our body tissues and bloodstream they can kill, and did so, frequently. One of my father's sisters died after a motorcycle accident in about 1930, due to wound infection. Another of his sisters died after childbirth in the late 1930s, probably due to infection. But for about 75 years we have been able to protect ourselves from these environmental bacteria by using antibiotics. One of my cousins suffered a minor cut on his foot while paddling in a river with his kids on a Sunday outing some years ago. On the Monday he collapsed at work and was rushed by ambulance to hospital as an assumed case of heart attack. Then the doctors realised he had blood poisoning. An immediate treatment with antibiotic saved his life. Otherwise he would have been killed by what would normally be described as an innocuous type of bacteria that lives a quiet, harmless life in a clean river. If we lose our antibiotics the greater danger will be from these types of bacteria and they can't be completely avoided by more hygiene.
After writing the above I saw this latest research on antibiotic resistant bacteria...
`Drug-resistant bacteria in patients’ urine or stools raise risk of drug-resistant sepsis'
21 April 2017 European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Under embargo until 22 April 2017 22:01 GMT
People who have recently been found to have drug-resistant bacteria in their urine or stool samples have a greatly increased risk of developing a bloodstream infection that is also resistant to certain antibiotics, according to a study presented at the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID). Sepsis affects an estimated 30 million people worldwide each year. Without quick treatment, it can lead to multiple organ failure and death. Treating sepsis can be even more difficult if the bacteria responsible are resistant to antibiotics. Presenting the research, Dr Joakim Isendahl from the Karolinska Institutet, Sweden told the congress that in some cases bacteria may be spreading from the bowel or urinary tract into the bloodstream, while in others the bacteria found in patients’ urine or stool samples could be transferring their ability to resist antibiotics to other bacteria in the body, which then can cause sepsis.....
