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 (First question answer: Pneumonia doesn't walk, but patients with walking pneumonia do!) is an imprecise term used to describe a person with symptoms of pneumonia that are mild enough to allow people to do daily activities and do not require patient hospitalization; it does not describe the cause of the pneumonia-like symptoms and is often used as a preliminary diagnosis without good evidence (a chest X-ray or other tests) that pneumonia is actually present.
