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]
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 36.8 ± 0.5 °C (98.2 ± 0.9 °F). [12]
L. interrogans cells are gram-negative, tightly coiled, motile spirochetes, with two periplasmic flagella. [1] One flagellum is inserted at each end of the bacterium. The cells are thin, about 0.15 μm, and long, between 6-20 μm, with a corkscrew shaped body with spiral or hooked ends. [1]
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3] [10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2]
Externally, the upper limit of the human body’s thermoneutral zone—the ambient temperature range in which the body can effectively maintain its temperature and equilibrium—likely falls ...
Leptospira noguchii are spirochete-shaped, gram-negative bacterium that typically range from 0.1 μm by 6 μm to 0.1 μm to 20 μm. [9] [10] Leptospira noguchii also lacks glycolipids in their peptidoglycan and contain diaminopimelic acid. [10] L. noguchii is a motile organism due to having amphitrichous flagella on opposing ends of each other ...
The minimal growth temperature of pathogenic species is 13–15 °C. Because the minimal growth temperature of the saprophytes is 5–10 °C, the ability of Leptospira to grow at 13 °C can be used to distinguish saprophytic from pathogenic Leptospira species. [30] The optimal pH for growth of Leptospira is 7.2–7.6.
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
