Summarize the following:
You need to limit the spread of the infection, which is done by keeping the infected horse away from uninfected horses. Where possible, it is best to isolate the horse for 2-3 weeks during and after treatment to reduce the risk of spreading the infection. In some cases, the horse's immune system will fight off the infection. In these cases the infection is considered 'self-limiting,' meaning that no treatment is necessary to cure that horse. However, because of the risk of infection and widespread shedding of fungus into the environment, it is advisable to treat ringworm before it has run its course. It can take around 6 - 15 weeks for self-cure to take place. During this time the horse is a source of infection to other horses. If the lesions are itchy and the horse rubs a lot, the ringworm patches may get infected are require further veterinary attention. Signs of infection include reddening of the area, inflammation, scabs formation, or weeping or discharge from the area. The first line of treatment is to use a topical treatment that is wiped over the affected areas to damage and kill the fungus. The product licensed for use in horses contains a drug called enilconazole (Imaverol). This is a liquid which damages the structure of the fungus and kills spores. It should be applied to the skin and hairs every three days for at least four treatments. Imaverol is concentrated and needs dilution prior to use. 1 ml of Imaverol is added to 50ml of water to make a 0.2% solution. It is best to spray the whole horse for the first treatment, in order to contact any fungus which is present but not yet showing signs of infection. After than it is acceptable to treat the infected areas only with a margin of skin around them to catch any sideways spread. The diluted Imaverol needs to contact the fungus, therefore scabs need to be removed first. This can be done by soaking them in a shampoo Malaseb (containing an antifungal agent, miconazole) and then picking them off or brushing gently with a toothbrush. Take care to wear gloves so that your skin doesn't become affected. After removing the scabs, thoroughly dry the skin so that water doesn't further dilute the Imaverol and weaken its action. Use any leftover Imaverol solution to wipe down reins and tack to decrease the risk of spread via equipment. It is also advisable to scrub down woodwork and surfaces with a 10% solution of bleach to kill the ringworm spores, which could pose a source of future infection. Oral medication, such as antifungal Griseofulvin, can be is added to the horse's feed. This treatment is usually reserved for hard-to-treat cases that are resistant to topical therapy. The horse receives treatment daily for 7 days. However, this treatment works from the inside out, and takes longer to be effective as the fungus need to contact the chemical in the blood. Also, some of the shed fungus could potentially still be infective.

summary: Isolate the infected horse. Assess whether treatment is necessary. Apply a topical treatment for ringworm. Clean all equipment and areas that the infected horse has been in contact with. Give your horse oral medication for ringworm if topical treatment is not effective.

Summarize the following:
Look for medium-sized rocks that appear to be more round than surrounding rocks. Geodes look a lot like normal rocks but can sometimes have an egg-like shape that distinguishes them. Sharp, pointy rocks rarely contain geodes. Look for rocks that have a unique, bumpy texture on the exterior. Geodes are rarely perfectly smooth. The texture of a geode's exterior may have a cauliflower-like appearance. Inspect the surface for any signs of minerals inside. Sometimes traces of the inside crystals are visible on the surface. Pick up the rock and assess its weight. If the rock feels lighter than that surrounding rocks, it may be a geode. Geodes have a hollow space inside, which is what allows the crystals to form. You can also shake the rock next to your ear to test whether it is hollow. You may hear small pieces of rock or crystal rattling around inside if it is hollow.
summary: Look for round rocks. Check the surface for bumps. Test whether the rock has a hollow interior.
