Top 10 Deadly Diseases are Transmitted Between Species

Category: Written by admin / 12.50

Bacteria and viruses are very simple creatures multiply and the disease it causes was highly infectious. Currently, a number of contagious and deadly disease has moved 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 the pathogen. Which gives pathogens the opportunity to exchange genes and equipment up to a previous killing foreign host.

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 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.

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

As reported by LiveScience, the following 10 deadly infectious disease from cross-species:

1. Pandemic influenza
Deadly flu pandemic like the Spanish flu, swine flu or bird flu has struck in several countries. Pandemic potential is very easily transmitted through direct contact, so that could be very dangerous.

Between 1918 and 1919, Spanish flu killed 20 to 40 million people. This is truly a global disaster. This deadly flu strikes people ages 20 to 40 years, and infects 28 percent of Americans.

And lately also emerging swine flu and bird flu 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
Bubonic plague is 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 a rat flea that is widely available in homes and offices.

3. Disease 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 and malaria.

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

HIV, the virus that causes AIDS, originated from chimpanzees and other primates and humans is expected to first become infected 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 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 peptic ulcers, Helicobacter pylori, the 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 in each of several outbreaks in the mid-1970s.

8. Polio, yaws, anthrax
Fabian Leendertz, a wildlife epidemiologist at the Robert Koch-Institute and 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 come from cattle that were herded by humans, although according to Leendertz this event may be caused by anthrax that exist 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 antibodies designed to fight germs. But the first evidence that was 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 'crab'
Humans get pubic lice from gorillas about 3 million years ago. The disease is not transmitted through sexual contact with gorillas, but by staying or dining at gorilla nest. Scientists in 2007 named the disease 'crab'.
