Weil's disease (/ ˈ v aɪ l z / VILES), [12] the acute, severe form of leptospirosis, causes the infected individual to become jaundiced (skin and eyes become yellow), develop kidney failure, and bleed. [6] Bleeding from the lungs associated with leptospirosis is known as severe pulmonary haemorrhage syndrome. [5]
Nonetheless, Koch was already aware that the causative agent of cholera, Vibrio cholerae, could be found in both sick and healthy people, invalidating his first postulate. [ 6 ] [ 9 ] Since the 1950s, Koch's postulates have been treated as obsolete for epidemiology research, but they are still taught to emphasize historical approaches to ...
In 1916, he described a disease with the symptoms urethritis, conjunctivitis and arthritis, which became known as Reiter's syndrome. Reiter was born in Reudnitz, near Leipzig in the German Empire . He studied medicine at Leipzig and Breslau (now Wrocław ), and received a doctorate from Tübingen on the subject of tuberculosis .
Diagnostic methods that can identify influenza include viral cultures, antibody- and antigen-detecting tests, and nucleic acid-based tests. Treatment of influenza in cases of mild or moderate illness is supportive and includes anti-fever medications such as acetaminophen and ibuprofen , adequate fluid intake to avoid dehydration, and resting at ...
An etiological agent of disease may require an independent co-factor, and be subject to a promoter (increases expression) to cause disease. An example of all the above, which was recognized late, is that peptic ulcer disease may be induced by stress, requires the presence of acid secretion in the stomach, and has primary etiology in ...
In biology, a pathogen (Greek: πάθος, pathos "suffering", "passion" and -γενής, -genēs "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. [1] The term pathogen came into use in the 1880s.
The Weil–Felix test is an agglutination test for the diagnosis of rickettsial infections. It was first described in 1916. By virtue of its long history and of its simplicity, it has been one of the most widely employed tests for rickettsia on a global scale, despite being superseded in many settings by more sensitive and specific diagnostic tests.
Fig. 1: Microwells showing positive and negative TPHA test. The Treponema pallidum particle agglutination assay (also called TPPA test) is an indirect agglutination assay used for detection and titration of antibodies against the causative agent of syphilis, Treponema pallidum subspecies pallidum. It also detects other treponematoses. [citation ...
