10 Dangerous Diseases

Bacteria and viruses are very simple creatures breed and the disease it causes highly contagious. There are currently 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 pathogens opportunity to exchange genes and equipment to kill foreign host before.

Transmission can also occur from activities that seem trivial and harmless, like letting a monkey riding on top of your head, which is a lot happening on the streets of Bali.

Microbes of 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.

Diseases transmitted 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 diseases that spread from cross-species :

1. Pandemic influenza. Deadly flu pandemic like the Spanish flu, swine flu or bird flu has struck in several countries. The pandemic potential of highly contagious through 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 catastrophe. 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 that has become epidemic in some countries. Now, the government is more prepared, scientifically and logistics to manage the outbreak. However, there is no vaccine against swine flu.

2. Pes. Bubonic plague, better known as the '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 fleas that is widely available in homes and offices.

3. Disease because of the bite. Zoonotic diseases are expected to increase due to an animal bite that kills hundreds of thousands of people every year. Mosquitoes are the main cause, such as dengue fever and malaria.

There was also an outbreak of disease caused by insect bites, rabies due to dog bites and other wildlife.

4. HIV/AIDS. HIV, the virus that causes AIDS, originated in chimpanzees and other primates, and an estimated first human infection is at least a century lalu. Virus damaging the immune sistem, opening the door to a host of deadly infections or cancer.

5. Cat brain parasites that are transmitted to humans. Strange 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 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 transmitted the bacteria that causes stomach ulcers, Helicobacter pylori, human ancestors thousands of years ago. And according to scientists, the disease has now spread 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 people who ate infected animals.

Now transmissible from human to human, through contact with blood or body fluids of an infected person, and has killed several hundred people in every several outbreaks in the mid-1970s.

8. Polio, yaws, anthrax. Fabian Leendertz, a wildlife epidemiologist at the Robert Koch-Institute and the Max Planck Institute for Evolutionary Anthropology in Germany, said that chimpanzees in Gombe Stream National Park in Tanzania is transmitted from human polio.

According Leendertz, there are also concerns that gorillas contracted yaws, a disease associated with syphilis, but not sexually transmitted diseases, of humans.

Gorillas and chimpanzees in West Africa has been killed by an outbreak of anthrax, which may come from cattle herded by humans, although according Leendertz these moments may be caused by naturally occurring anthrax in the woods.

9. Human virus killing chimps. Ecotourism trigger outbreaks of respiratory disease among the African chimpanzees. Human respiratory syncytial virus (HRSV) and human metapneumovirus (HMPV) killing human infants in developing countries.

Almost all humans have contact with germs, although it has developed alami antibodies designed to fight germs. But the first evidence that has been confirmed on penularanvirus directly from humans to wild apes, the virus is killing the entire population of chimpanzees in some parts of West Africa in 1999 and 2006.

10. Gorillas gave human pubic lice 'crab'. Humans get pubic lice from gorillas about 3 million years ago. The disease is not transmitted through sexual contact with gorillas, but with overnight stay or eat in gorilla nests. Scientists in 2007 named the disease 'crab'
