Heart - Heart! 10 Dangerous Diseases Transmitted Between These Species
Bacteria and viruses are being very easy to breed and the disease it causes is very contagious. At present a number of infectious and deadly diseases have been transferred from animals to humans and from humans to animals. What are the deadly disease?
Cross-species infection can originate from farms or markets, which creates conditions of mixing of pathogens. Which gives an opportunity to exchange genes of pathogenic and equipment up to kill previously foreign hosts.
Transmission also can occur from activities that seem trivial and harmless, like letting a monkey riding on top of your head, a lot happens on the streets in Bali.
Microbes of two varieties can even gather in your intestines, the virus evolved and make some 'dancing' to turn you into a host of infectious and lethal.
Infectious diseases from animals to humans are called zoonoses. There are more than three dozen diseases that are transmitted through touch or from the bite.
As reported by LiveScience, Saturday (15/05/2010), the following 10 deadly disease that spreads from cross-species:
1. Pandemic influenza. Lethal flu outbreaks such as the Spanish flu, swine flu or bird flu has been attacked in several countries. Pandemic potential is very easily transmitted by direct contact, so it can be very dangerous.
Between 1918 and 1919, the Spanish flu killed 20 to 40 million people. This is truly a global disaster. This deadly flu strikes people aged 20 to 40 years, and infect 28 percent of Americans.
And lately also emerging swine flu and bird flu which has become epidemic in some countries. Now, governments are more prepared, scientifically and logistics to manage the outbreak. However, there is no vaccine against swine flu.
2. Pes. Bubonic plague is better known as the 'Black Death', is an infectious disease caused by the bacterium Yersinia am absolutely, most often carried by rodents and fleas. In medieval times, millions of people across Europe died from plague caused by rat infestation that is widely available in homes and offices.
3. Disease because of the bite. Zoonotic diseases are expected to increase due to the bite of an animal that kills hundreds of thousands of people every year. Mosquitoes are the main cause, such as dengue and malaria.
There was also an outbreak of disease caused by insect bites, rabies due to dog bites and other wild animals.
4. HIV / AIDS. HIV, the virus that causes AIDS, originated from chimps and other primates and the first human infection is estimated at least a century this lalu.Virus damage the immune system, opening the door to a host of deadly infections or cancer.
5. Cat brain parasite that is transmitted to humans. Bizarre parasite Toxoplasma gondii infects the brains of more than half the human population, including approximately 50 million Americans. Predicted increased risk of neuroticism and could lead to schizophrenia. The main cause is a house cat, which is the sexual reproduction of microbes. This usually comes from cat feces.
6. Humans give cats the bacteria that cause stomach ulcers. Cats have been transmitted bacterium that causes peptic ulcers, Helicobacter pylori, from our ancestors thousands of years ago. And according to scientists, this disease is now spreading to other animals such as lions, zebras, and tigers.
7. Ebola. Ebola is a widespread threat to gorillas and chimpanzees in Central Africa, and may have spread to humans from the people who eat infected animals.
Now transmitted from human to human, through contact with blood or body fluids of an infected person, and have killed several hundred people in each several outbreaks in the mid-1970s.
8. Polio, yaws, anthrax. Fabian Leendertz, a wildlife epidemiologist at the Robert Koch-Institut and the Max Planck Institute for Evolutionary Anthropology in Germany, said that the chimpanzees at Gombe Stream National Park in Tanzania spread of polio from humans.
According Leendertz, there are also concerns that gorillas contracted yaws, a disease associated with syphilis, but not the sexually transmitted diseases, of humans.
Gorillas and chimpanzees in West Africa have been killed by the anthrax outbreak, which may have originated from cattle herded by humans, although Leendertz by these events may be caused by anthrax that occurs naturally in the forest.
9. Human viruses kill the chimp. Ecotourism trigger an outbreak of respiratory disease among African chimpanzees. Human respiratory syncytial virus (HRSV) and human metapneumovirus (HMPV) kill humans infants in developing countries.
Almost all humans have contact with the bacteria, although it has developed natural antibodies designed to fight germs. But the first evidence that has been confirmed on penularanvirus directly from humans to wild apes, the virus has killed entire populations of chimpanzees in some parts of West Africa in 1999 and 2006.
10. Gorillas gave humans pubic lice "crabs". Humans get pubic lice from gorillas about 3 million years ago. The disease is not transmitted through sexual contact with the gorillas, but by staying in gorilla nests or eating. Scientists in 2007 named the disease 'crabs'.
