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. When humans infect non-humans, it is called reverse ...
Streptococcus suis is a peanut-shaped, Gram-positive bacterium, and an important pathogen of pigs. Endemic in nearly all countries with an extensive pig industry, S. suis is also a zoonotic disease, capable of transmission to humans from pigs.
Although a variety of infectious diseases existed in the Americas in pre-Columbian times, [1] the limited size of the populations, smaller number of domesticated animals with zoonotic diseases, and limited interactions between those populations (as compared to areas of Eurasia and Africa) hampered the transmission of communicable diseases.
Brucellosis [4] is a zoonosis caused by ingestion of unpasteurized milk from infected animals, or close contact with their secretions. [5] It is also known as undulant fever, Malta fever, and Mediterranean fever. [6] The bacteria causing this disease, Brucella, are small, Gram-negative, nonmotile, nonspore-forming, rod-shaped (coccobacilli ...
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
Cats and dogs can acquire the disease from the bite of a tick or flea that has fed on an infected host, such as a rabbit or rodent. For treatment of infected cats, antibiotics are the preferred treatment, including tetracycline, chloramphenicol or streptomycin. Long treatment courses may be necessary as relapses are common. [51]
If the outbreak is detected early, the organism can be destroyed by quarantines, movement controls, and the euthanasia of infected animals. Tsetse fly populations can be reduced or eliminated by traps, insecticides, and by treating infected animals with antiparasitic drugs. The tsetse habitat can be destroyed by alteration of vegetation.
All infected cats require supportive care, including careful fluids, nutritional support, treatment for complications, and often blood transfusion. [ 11 ] Cats that survive the infection should be kept indoors as they can be persistent carriers after surviving infection and might indirectly infect other cats after being themselves bitten by a ...
