Lower Respiratory Tract Infection (LRTI) Caused By Susceptible Bacteria

Lower respiratory tract infections (LRTI) are a collective term to describe the inflammation of the lower airways and affected by various organisms, such as viruses and bacteria. While LRTIs can be caused by a variety of bacteria or viruses, they are most commonly caused by bacteria that are susceptible to antibiotics.

Bacterial infections can cause various forms of lower respiratory tract infection, such as pneumonia, bronchitis, and tracheitis. The bacteria that cause these infections are often the same bacteria that cause other illnesses, and they can often be treated with antibiotics.

There are several different types of bacteria that are known to cause lower respiratory tract infections. They include:

• Streptococcus pneumoniae (pneumococcus): A gram-positive bacteria found in the throat, nose, and upper respiratory tract.
• Haemophilus influenzae: A gram-negative bacteria that can cause ear infections and meningitis.
• Mycoplasma pneumonia: A type of gram-negative bacteria.
• Legionella pneumonia: A type of bacteria that can cause a severe form of pneumonia.
• Staphylococcus aureus: A gram-positive bacteria.
• Klebsiella pneumoniae: A type of gram-negative bacteria.

The most common symptoms associated with lower respiratory tract infection include: cough, fever, difficulty breathing, chest pain, and bloody sputum. If left untreated, LRTIs can lead to complications such as sepsis, organ failure, or even death.

In order to treat an LRTI caused by susceptible bacteria, patients may be prescribed antibiotics. It is important to finish the entire dose of antibiotics as prescribed, even if the symptoms subside. Otherwise, the infection may return, and may be more resistant to treatment.

In addition to taking antibiotics, it is important to get plenty of rest and drink plenty of fluids. A humidifier can also be used to make breathing easier. If the symptoms worsen or do not improve with treatment, it is important to contact a doctor right away.
