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 ]
Leptospirosis in canines can be divided into the four categories of reproductive, icteric, hemorrhagic, and uremic. Reproductive leptospirosis results in the premature birth of offspring or abortion, and uremic leptospirosis is referred to as Stuttgart disease. [32] L. interrogans triggers a highly inflammatory response in infected dogs.
Leptospira (from Ancient Greek λεπτός (leptós) 'fine, thin, narrow, etc.' and Latin spira 'coil') [1] is a genus of spirochaete bacteria, including a small number of pathogenic and saprophytic species. [2]
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] The disease is normally absorbed through the mucous membranes of another animal or human and is excreted from the body in the urine. [ 7 ]
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.
It’s a common virus that causes illness in the upper and lower respiratory tracts, Dr. William Schaffner, a professor of infectious disease at the Vanderbilt University Medical Center, tells ...
Rabbits had been brought to the continent in 1859 for sport, and having no natural predators, bred at an extraordinary rate. The infection killed 99.8 percent of rabbits, but by the late 1950s, Australian rabbits started to become immune to the virus and the population of rabbits increased, but never to the vast numbers seen before 1950.

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.
