athete foot

Athlete's foot typically affects the skin on the feet between the toes, but can move anywhere on the foot and can affect the toenails.

Athlete's foot is a fungi infection of the skin and the nails, usually found on the skin between the toes. When the infection spreads to the toenails, they become thick and distorted.

Fungi are plant organisms (tinea Pei such as mold and mildew and grow best in conditions that are moist. Bacteria may spread as a secondary infection, which worsens the symptoms of the disorder and makes it more difficult to cure. A fungal infection is one of the most difficult nail and foot conditions to treat.

It is common to catch athlete's foot from other people who have it by walking on floors that are moist or wet at swimming pools and in shared bathroom facilities). Athlete's foot is also much more common in people who tend to have moist feet. Athlete's foot can also be spread by sharing other people's shoes or personal care items such as towels and wash cloths.

Athlete's foot and fungus may also spread to other parts of the body, notably the groin and underarms, by those who scratch their and then touch themselves elsewhere.


Symptoms
On the skin Reddened, cracked, and peeling skin Some bleeding Itching Burning
small blisters .Blisters often lead to cracking of the skin. When blisters break, small raw areas of tissue are exposed, causing pain and swelling. Itching and burning may increase as the infection spreads. In severe cases the skin may thicken, callus.

Change in color yellow or brown Nail gets thicker Bad odor
mildew collects beneath the nail White marks on the nail.

how do some fungi attack plants

Fungi can't make their own food, so they must somehow get it from other organisms, living or dead. Some fungi can digest things like dead leaves and wood. Others set up mutually beneficial relationships with living plants . But a third group discovered how to attack plants and steal food from them.

These pathogenic or disease-causing fungi get inside the plant either by making a hole in its skin epidermis, or by growing in through the plant's breathing holes stomata. Then they either poison and kill the plant cells before absorbing food from them, or simply steal nutrients from the living cells.

The spores of some fungi come through the air and attack leaves, making dead spots or even killing the whole leaf. Some fungi live in the soil and enter roots. They can either block the water-conducting cells or kill them, causing the plant to wilt. In many cases the plants is seriously damaged or may even die. So such pathogenic fungi can threaten our crops. The study of these fungi is called plant pathology.



this video right here is a amazing link to a video that basicly blew my mind to see how BIG they grow! http://www.youtube.com/watch?v=puDkLFcCZyI

maLARIA

Malaria is a mosquito disease caused by a parasite. People with malaria often experience fever, chills, and flu . Left , they may develop severe complications and die. Each year 350-500 million cases of malaria occur worldwide, and over one million people die, most of them young children in Africa south of the Sahara.

This sometimes disease can be prevented and cured. Bednets, insecticides, and antimalarial drugs are effective tools to fight malaria in areas where it is transmitted. Travelers to a malaria risk area should avoid mosquito bites and take a preventive antimalarial drug.

MALARIA

Today I learned a lot about Malaria.  I found out that it is not the mosquito, but the protist living in the mosquito.
