Leptospirosis is a blood infection caused by the bacterium Leptospira [8] that can infect humans, dogs, rodents and many other wild and domesticated animals. [8] Signs and symptoms can range from none to mild (headaches, muscle pains, and fevers) to severe (bleeding in the lungs or meningitis). [5]
The icteric form is also known as Weil's disease. [29] It has been shown in studies that L. interrogans may damage the endothelial cell lining of various vessels and organs, allowing them to leak and further spread the bacteria to other parts of the body. [30] Symptoms can appear anywhere between 2 and 4 weeks after exposure.
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

Drs. Eugeniusz Lazowski and his medical-school friend Stanisław Matulewicz were practicing in the small town of Rozwadów in Poland during World War II.Dr. Matulewicz realized that since Proteus vulgaris strain OX19 was used to manufacture the then-common Weil-Felix antibody-agglutination test for typhus, inoculating villagers with dead Proteus would cause a false positive result without ...
The ID 50 (the dose needed to infect 50% of experimental subjects) is one via inhalation; i.e., inhalation of one organism will yield disease in 50% of the population. This is an extremely low infectious dose (only 1-10 organisms required), making C. burnetii one of the most infectious known organisms.
DR.WEIL'S ANTI-INFLAMMATORY DIET is designed to reduce chronic inflammation and related chronic diseases, like heart disease, diabetes, Alzheimer’s, and others, Harbstreet says. It also aims to ...
The cheapest and most easily available serological test is the Weil-Felix test, but this is notoriously unreliable. [15] The best test is indirect immunofluorescence , [ 16 ] but the main limitation of this method is the availability of fluorescent microscopes, which are not often available in resource-poor settings where scrub typhus is endemic.
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 ...
