10 Deadly Diseases transmitted among species

Bacteria and viruses are very simple creatures multiply and the disease it causes highly contagious. Currently a number of contagious and deadly disease has been transferred from animals to humans and from humans to animals. What are the deadly disease?

Cross-species infection could come from farms or markets, which creates conditions of mixing of pathogens. Which gives pathogens the opportunity to exchange genes and equipment up to a previous killing of foreign host.

Transmission can also 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 from the two varieties can even be assembled in your intestines, the virus evolved and make some 'dancing' to turn you into a host of infectious and deadly.

Infectious diseases from animals to humans is called zoonosis. There are more than three dozen diseases, whether transmitted through touch as well as from the bite.

As quoted from LiveScience, Saturday (15/05/2010), the following 10 deadly infectious disease from cross-species:

1. Influenza pandemics
   Deadly flu pandemic like the Spanish flu, swine flu or bird flu has struck in several countries. Potential pandemic is very easily spread by direct contact, so that could be very dangerous.
   
   Among years 1918 and 1919, Spanish flu killed 20 to 40 million people. This is truly a global disaster. This deadly flu attacked people ages 20 to 40 years, and infects 28 percent of Americans.
   
   And lately also emerging swine flu and avian influenza that has become epidemic in some countries. Now, governments are better prepared, scientifically and logistics to manage the outbreak. However, there is no vaccine against swine flu.
    
2. Plague
   Pestilence known as 'Black Death', is an infectious disease caused by the bacterium Yersinia pesti, 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. Diseases due to bites
   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 causes, such as dengue fever and malaria.
   
   There was also a disease outbreak caused by insect bites, rabies due to dog bites and other wild animals.
    
4. HIV / AIDS
   HIV, the virus that causes AIDS, originated from chimpanzees and other primates and the first human infection is estimated at least a century ago. The virus is damaging the immune system, opening the door to a host of deadly infections or cancer.
    
5. Cat brain parasite that is transmitted to humans
   Weird parasite Toxoplasma gondii infects the brain more than half the human population, including about 50 million Americans. Estimated to increase the risk of neuroticism and can cause schizophrenia. The main cause is the cat's house, 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, an ancestor of mankind since 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 transmit from human to human, through contact with blood or body fluids from an infected person, and has killed several hundred people at each of 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 a sexually transmitted disease, from humans.
   
   Gorillas and chimpanzees in West Africa have been killed by the anthrax outbreak, which may have originated from cattle herded by humans, though according to Leendertz this event may be caused by anthrax that is naturally in the forest.
    
9. Human viruses kill chimps
   Ecotourism trigger outbreaks of respiratory disease among African chimpanzees. Human Respiratory Syncytial Virus (HRSV) and Human Metapneumovirus (HMPV) to kill human babies in developing countries.
   
   Almost all humans have contact with germs, although it has developed a natural antibody designed to fight germs. But the first evidence that has been confirmed on direct virus transmission 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. This disease is not transmitted through sexual contact with a gorilla, but with overnight stay or dining in gorilla nests. The scientists named the disease in the year 2007 'crab'.
