[5] [6] [7] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung. [8] [9] In most cases patients with NP have fever, cough and bad breath, and those with more indolent infections have weight loss. [10]
Diagnosis of pneumonia is made clinically, rather than on the basis of a particular test. [13] Evaluation begins with a physical examination by a health provider, which may reveal fever, an increased respiratory rate ( tachypnea ), low blood pressure ( hypotension ), a fast heart rate ( tachycardia ) and changes in the amount of oxygen in the ...
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [3] [14] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [15]
[6] S.pneumoniae growth on blood agar. Streptococcus pneumoniae can be differentiated from the viridans streptococci, some of which are also alpha-hemolytic, using an optochin test, as S. pneumoniae is optochin-sensitive. S. pneumoniae can also be distinguished based on its sensitivity to lysis by bile, the so-called
The genus Klebsiella was named after the German microbiologist Edwin Klebs (1834–1913). [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics.
The term mycoplasma (mykes meaning fungus, and plasma, meaning formed) is derived from the fungal-like growth of some mycoplasma species. [6] The mycoplasmas were classified as Mollicutes (“mollis”, meaning soft and “cutis”, meaning skin) in 1960 due to their small size and genome, lack of cell wall, low G+C content and unusual nutritional needs.
The Peabody Picture Vocabulary Test, the 2007 edition of which is known as the PPVT-IV, is an untimed test of receptive vocabulary for Standard American English and is intended to provide a quick estimate of the examinee's receptive vocabulary ability. It can be used with the Expressive Vocabulary Test-Second Edition (EVT-2) to make a direct ...
Notably, simple molecular detection of P. jirovecii in lung fluids does not mean that a person has PCP or infection by HIV. The fungus appears to be present in healthy individuals in the general population. [14] A blood test to detect β-D-glucan (a part of the cell wall of many different types of fungi) can also help in the diagnosis of PCP.
