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 ]
Leptospira is one of the genera of the spirochaete phylum that causes severe mammalian infections. [3] This species is pathogenic to some wild and domestic animals, including pet dogs. It can also spread to humans through abrasions on the skin, where infection can cause flu-like symptoms with kidney and liver damage. [ 2 ]
Leptospira noguchii is another pathogenic bacteria that causes Leptospirosis. Leptospirosis can be transferred in a multitude of ways. Leptospirosis can transfer from animals to humans , humans to humans, or animals to animals via intake of contaminated body fluids, such as urine and blood. [7]
Leptospirosis: Caused by bacterium of genus Leptospira: Water contaminated by the animal urine carrying the bacteria Begins with flu-like symptoms then resolves. The second phase then occurs involving meningitis, liver damage (causes jaundice), and kidney failure: Otitis Externa (swimmer's ear) Caused by a number of bacterial and fungal species.
One or both ends of the spirochete are usually hooked. Because they are so thin, live Leptospira are best observed by darkfield microscopy . The bacteria have a number of degrees of freedom; when ready to proliferate via binary fission , the bacterium noticeably bends in the place of the future split.
About 200 Americans are killed per year by animals, according to one study, and the most common perpetrators may be surprising. A recent Washington Post analysis of government data between 2001 ...
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human.
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.
