It is important to address that boy may has exercise-induced asthma.
Exercise-induced asthma is a narrowing of the airways in the lungs triggered by strenuous exercise. It causes shortness of breath, wheezing, coughing, and other symptoms during or after exercise.
The more preferred term for this condition is exercise-induced bronchoconstriction.
Kids with EIB should be able to take part in activities; they just may need medication before an activity.
There are three types of medicines to prevent or treat the symptoms of EIB.
They are short-acting bronchodilator (taken 10-15min before the activity), long-acting bronchodilator (taken 30-60min before the activity) and mast cell stabilizers (taken 10-15min before the activity).

The mechanism by which genes are transferred from a donor to a recipient microorganism is called TRANSDUCTION. After transduction, the genetic makeup of the recipient cell is different.
Transduction refers to the genetic recombination mechanism by which bacteria can transfer fragments of DNA by using bacteria-infecting viruses called bacteriophages.
During transduction, a bacterial cell interacts by a conjugal bridge through which fragments of DNA are transferred to a suitable (host) recipient cell.
This mechanism (transduction) changes the genome of the host cells by generating genetic recombinants when the bacteriophages initiate a new cycle of infection.
