An antibiotic is a drug that treats infections caused by bacteria.
There are many different types of antibiotics, some are bactericidal
(kill bacteria), such as penicillin. Other antibiotics, such as
bacteriostatic (stop bacteria from growing and multiplying). Over the
years, antibiotics helped to bring under control many serious infectious
diseases that were previously untreatable and frequently fatal.
the widespread use of antibiotics, repeated or used incorrectly, there
is a chance that the bacteria will become resistant. This means that the
antibiotic becomes less effective against that type of bacterium. The
bacteria survive exposure to an antibiotic and continue to multiply
causing more harm. Some bacteria can be resistant to more than one
antibiotic class and these are called multi-resistant.
Antibiotic therapy can lead to overgrowth of potentially antibiotic-resistant pathogenic bacteria and fungi, such as Stahylococcus aureas
, Escherichia coli
and Candida albicans
Probiotics are live beneficial microorganisms from the human gut which
help to maintain protective gut microflora, reduce survival of
pathogenic or bad bacteria. The most common probiotic bacteria are the Lactobacilli
study carried out at the Addenbrooke's Hospital in Cambridge, UK,
followed 30 patients requiring the same antibiotic therapy. The patients
were divided into the two groups and supplemented with probiotic
containing 25 billion live bacteria per daily dose or placebo capsule in
conjunction with antibiotics. None of the participants knew if they
were taking probiotic or placebo.
demonstrated that supplementation of probiotics with 25 billion live
bacteria per dose daily helped maintained the balance of gut microflora
during antibiotic therapy. The group without probiotic supplement
resulted in double the amount of "bad" bacteria (total fecal number of
coliforms, staph. aureas and enterocci) prior initiating antibiotic
treatment. Overgrowth of pathogenic bacteria can lead to
gastrointestinal problems such as gas and bloating, abdominal pain,
diarrhea and more.
