Presentation
Abstract A clinical efficacy study of amikacin in the treatment of 15 adults with nonbacteremic, gram-negative bacillary pneumonia is presented. [ncbi.nlm.nih.gov]
The ORs compared with the baseline value (patients with no risk factor present) were 4.2 (95% CI, 1.4-16.7) for 1, 9.1 (95% CI, 2.8-37.2) for 2, and 39.3 (95% CI 9.3-188.3) for 3 or more risk factors present on admission. [jamanetwork.com]
It is impossible to present precise incidence figures, as these vary from centre to centre and are influenced by diagnostic sensitivity, patient populations, etc. [cambridge.org]
The present review has the aim to update the current knowledge about the etiology, classifi cation, antimicrobial resistance, diagnosis, and therapy in CAP due to GNB. [caijournal.com]

Fever
Essentially, all had new lung infiltrates as shown by chest radiography, leukocytosis, recent onset of fever, and increased volume of purulent secretions. Half had multilobar pulmonary infiltrates. [ncbi.nlm.nih.gov]
This results in the fever, chills, and fatigue common in bacterial and fungal pneumonia. The neutrophils, bacteria, and fluid leaked from surrounding blood vessels fill the alveoli and result in impaired oxygen transportation. [en.wikipedia.org]

Your doctor might also suggest medication for pain and fever. Other things you can do to help yourself get better: Get lots of rest. Drink plenty of fluids (they’ll loosen up the gunk in your lungs so you can cough it out). [webmd.com]

Preventing pneumonia is always better than treating it. Vaccines are available to prevent pneumococcal pneumonia and the flu. Other preventive measures include washing your hands frequently and not smoking. [icdlist.com]
