defensin
The antibiotic tested is not likely to be effective in eradicating the infection. *The infectious agents are a strain that have developed (evolved) a natural resistance to a particular antibiotic.
Cytokines such as interferrons and interleukins are secreted by the T cell in response to antigen. These chemicals are also secreted by B cells, dendrictic cells and natural killer cells. These chemicals are signalling agents that modulate (or properly control) the immune response
antibiotics can be obtained from micro organisms by fermentation or by semisynthetically and those can be called as natural. and some antibiotics can be prepared synthetically by series of chemical reactions. those are synthetic antibiotics. penicillin is natural antibiotic which is obtained from P. notatum so it is natural antibiotic. and chloramphenicol is synthetic
circulatory system and respiratory system are 2 examples

human respiratory uses air pressure like pneumatic system does

Consider the following scenario: An antibiotic is applied to a petri dish of bacteria. The antibiotic will kill of most of the bacteria, but some will remain that are immune to the antibiotic. Therefore, only the immune bacteria will reproduce. Soon, the whole petri dish will be full of bacteria that is immune to the antibiotic. Nature "selects" the immune bacteria for survival.
Antibiotic treatment for bacterial infections can produce yeast infections. Yeast infections due to antibiotic treatment are caused by the destruction of good and bad bacteria, and disrupts the vaginal flora.

ventilator
as the bacteria it was exposed to, eventually one strain mutated and this lead to a resistance to the antibiotic, and therefore the bacteria with the mutation was able to reproduce, where as the other bacteria would have been killed off by the antibiotic. Thus natural selection is achieved, yipee!(not for us)
it's garlic, it contains alicin a powerfull natural antibiotic which does not atack healthy bacteria in your gut.
The red sweat is a natural antibiotic sunscreen to protect them from the heat and sun.
