Pneumonia clinical presentation

As stated in the clinical presentation of community-acquired or aspiration pneumonia. 

Signs and Symptoms Diagnosis of psittacosis can be difficult. There is a variable clinical presentation but may include fever, headache, muscle pain (myalgia), chills and upper or lower respiratory tract disease, and dry cough. Pneumonia is often evident in chest x-rays. 

Tularemia pneumonia can result from an inhalation exposure or from hematogenous spread of the infection. An aerosol release could be expected to result in large numbers of patients experiencing systemic symptoms accompanied by signs and symptoms associated with one or more of the following conditions pharyngitis, bronchiolitis, pleuropneumonitis and hilar lymphadenitis (43). However, many people with inhalational exposure will likely develop a clinical presentation of systemic symptoms without prominent signs or symptoms of respiratory disease.

The clinical presentation of pneumonia in HIV-infected persons is frequently not helpful in distinguishing one pathogen from another. 

Colonization does not occur with Blastomyces. Acute pulmonary blastomycosis generally is an asymptomatic or self-limited disease characterized by fever, shaking chiUs, and productive, purulent cough, with or without hemoptysis, in immunocompetent individuals. The clinical presentation may be difficult to differentiate from other respiratory infections, including bacterial pneumonia, on the basis of clinical symptoms alone. 

Clinical and Pathological Features Patients with asbestosis usually are clinically similar to those with usual interstitial pneumonia and present with shortness of breath, dry cough, and Velcro rales at the lung... 

Methicillin-resistant Staphylococcus aureus (MRSA) is a common hospital-acquired pathogen and is also increasing in the community. MRSA has presented a problem in the past because it required treatment with vancomycin. Community-acquired MRSA presents a major therapeutic challenge. MRSA can cause pneumonia, cellulitis, and other infections. Clinicians should be aware of the rate of hospital and community MRSA in your geographic area. New treatment options are available for MRSA. They include linezolid, tigecycline, and daptomycin. Prospective clinical trials have not demonstrated benefits of these agents over vancomycin.36-37...
