No, diesel engines don't have ignition coil as they work on compression ignition and not on spark ignition as in diesel engines. Glow plugs used in diesel are like small electric heaters which use the mechanism of heating due to resistance during electrification.
Clarithromycin is another antibiotic treatment for walking pneumonia. It is more powerful than even erythromycin as it is also used to help treat HIV/AIDS patients. It works by interfering with the protein synthesis of bacteria, which prevents them from growing further. It is given in the form of tablets or a gel.
Walking pneumonia is simply a milder case of pneumonia. It can be caused by a number of different types of bacteria and viruses. The most common organism responsible is the bacteria Mycoplasma pneumoniae. The viruses and bacteria that cause walking pneumonia are contagious. However, it is unlikely that a person with walking pneumonia would give another person this condition. Instead, when spread, these germs are more likely to cause upper respiratory infections such as the common cold or flu.
