How does pneumonia interfere with gas exchange?

Each one has a fine mesh of capillaries. This is where oxygen is added to the blood and carbon dioxide is removed. If a person has pneumonia, the alveoli in one or both lungs fill with pus and fluids (exudate), which interferes with the gas exchange. This is sometimes known as ‘consolidation and collapse of the lung’.

Is chloramphenicol Gram positive or negative?

Chloramphenicol is a broad-spectrum antibiotic whose spectrum includes several gram-positive and gram-negative bacteria, spirochetes, and Rickettsiae.

What bacteria is resistant to chloramphenicol?

Pseudomonas putida KT2440 is a chloramphenicol-resistant bacterium that is able to grow in the presence of this antibiotic at a concentration of up to 25 μg/ml.

What causes bronchopneumonia?

Causes and risk factors The most common cause of bronchopneumonia is a bacterial lung infection, such as Streptococcus pneumoniae and Haemophilus influenza type b (Hib). Viral and fungal lung infections can also causes pneumonia. Harmful germs can enter the bronchi and alveoli and begin to multiply.

What organs are affected by pneumonia?

Pneumonia is an infection that affects one or both lungs. It causes the air sacs, or alveoli, of the lungs to fill up with fluid or pus. Bacteria, viruses, or fungi may cause pneumonia.

Which class of antibiotics is chloramphenicol?

Chloramphenicol is an antibiotic and is in the class of antimicrobials that inhibits protein synthesis.

Is chloramphenicol effective against S aureus?

Chloramphenicol, in comparison with tobramycin, was more active against S. aureus, and less active against P. aeruginosa, although chloramphenicol also significantly reduced bacterial adhesion even when the lenses were colonized by P.

What class of antibiotic is chloramphenicol?

Is E. coli resistant to chloramphenicol?

Seventy-three percent of the E. coli isolates were resistant to five or more antibiotics. Interestingly, 53% of swine E. coli isolates exhibited resistance to chloramphenicol (CHL), an antibiotic whose use in food animals has been prohibited in the United States since the mid-1980s.

What are the 4 different types of pneumonia?

These are:

  • Bacterial pneumonia. This is caused by bacteria, the most common of which is streptococcus pneumoniae.
  • Viral pneumonia. Responsible for about one-third of all pneumonia cases, this type is caused by various viruses, includingflu (influenza).
  • Mycoplasma pneumonia.
  • Fungal pneumonia.
