Um, this is a very misleading article. there are countless studies providing proof that antibiotics are extremely dangerous drugs, not fantastic. You claimed they effectively kill bacteria and clear up infection, but that's like saying chemotherapy is the best option for cancer and is fantastic. In a way, they both disrupt their targeted environment by mostly being unable to control what they kill. This is the main reason they're both dangerous and should only be used if a100 percent life saving necessity.
Personally, as far as chemo goes, it as a treatment that should never be considered an option and whenever I receive a positive cancer reading, I'll absolutely reject chemo altogether, but that's another topic on its own. The reason I bring up chemo is because they're both linked to forms of worse side effects than benefits. They both kill the surrounding healthy inhabitants (chemo kills healthy cells and antibiotics kill healthy gut and surrounding area bacteria). Neither have nor ever will be able to control the population targeting – only the "bad" corrupting the environment allowing a worse spread of infection.
Antibiotics, alongside chemo, should only be taken if needed, not whenever. Sites such as this one promote bad information to those who don't fully look into studies available. The true risk of side effects comes with all unnatural treatment options (modern medicine/pills/drugs) which is why it's important to discuss which antibiotics you take if you should ever choose to put yourself in a position of danger by taking these courses of drugs. You also run the risk of allowing your system to get used to treatments, but these drugs are most famous for their adaptability, which risks treatment failure. This is a topic not explained by health professionals, so be sure to discuss all options with your family doctor/health care provider at the time of care before choosing antibiotics. There may be another way.
My last point, if I failed at drilling how dangerous this option is into your head, touches on my secondary warning. There has been a great deal of study on major breakouts involving a form of CER called NDM-1. It's pretty much antibiotic-resistant. There is one select very nasty bacteria called C. Diff. You hear about it as being the most popular form of resistant strains breaking out in such places as hospitals. At least one period every year is infected by this one strain in hospitals. It is caused by a bacteria that has built up resistance to antibiotics.
So please do your research or better yet, second guess the information sites offered by your own personal research. Explore treatment options with you doctor and think of these drugs as non-safe or in the same class as chemo. There are more cons than pros. Ask your pharmacist about the prevention of side effects that come along with taking drugs instead of self exploration on sites. Your pharmacist and GP doctor can help customize a personal plan to fit your needs, and always ask questions.
