What is Kyowave?

Kyowave is a new product from Cryochaps that can help in the fight against Mud Fever. It’s an easy to use boot that harnesses the bactericidal effects of blue light therapy.

Blue light, has attracted increasing attention due to its intrinsic antimicrobial effect. Blue light therapy is a clinically accepted approach for acne infections and clinical trials have also been conducted to investigate the use of blue light for Helicobacter pylori stomach infections with promising results.  The interest in blue light has largely been driven by the increase in drug resistance among many classes of pathogen. Advantages include equal killing effectiveness regardless of antibiotic resistance, and a lack of resistance.

What is Mud Fever?

Mud Fever, pastern dermatitis, greasy heels and cracked heels, are all names given to a condition that can take over your life as a horse owner. Box rest, trying every lotion and potion in the book, plus those prescribed by vets with antibiotics and steroids. Mud Fever is usually seen most commonly during wet and muddy conditions but even heavy dew in the summer mornings can cause skin lesions, these ones more commonly known as dew burn. More often than not it effects the white, pink skinned heels, but your black hairy heels are not immune. Left untreated or unseen, hiding in the hairy legs, it can fester and become a major issue. Crusty, scabby, red, sore areas of the skin that sometimes weep, legs swell and become painful which causes obvious discomfort for the horse.

How does it happen? The most common cause is bacteria but fungus and mite infection have also been seen to play a part. Wet skin becomes softer and more prone to abrasion, so in the muddy conditions the protective outer skin layer becomes damaged, this creates a great environment for the bacteria to take hold as the skins protective barrier is weakened. Leg mites can also cause damage to the skin which allows bacteria to enter, or perhaps a rub caused by overreach boots, used when exercising.

So, which bacteria are commonly found in the wounds when swabbed? Staphylococcus, Streptococcus and Pseudomonas are the most common along with many commensal bacteria. These usually grow when mud fever is swabbed for culture.

Mud Fever

Kyowave has been tested on this horse suffering from mud fever. A vet swabbed the area on day 0 and day 8. Kyowave was applied to both front pasterns for 30mins daily.

Swabs and scabs cultured on day 0, showed, beta-heamolytic streptoccus spp, coagulase-negative staphyloccus and pseudomonas spp. All of which were absent on day 8 swab on the two legs that had Kyowave application. After 2 months the pastern dermatitis totally disappeared.

What does the blue light do?

It has been found across many trials that blue light can mediate a broad-spectrum antimicrobial effect. Kyowave has been manufactured to produce blue light with a precise wavelength that is reported to have the most bactericidal effect.

Studies on blue light inactivation of important wound pathogenic bacteria, including Staphylococcus aureus and Pseudomonas aeruginosa are well reported. The mechanism of blue light inactivation for many bacteria is photo-excitation of intracellular porphyrins and the subsequent production of cytotoxic reactive oxygen species. These reactive oxygen species damage internal structures within the bacterial cell, such as DNA and cause cell death.

The specific wavelength of light used in Kyowave has been seen to destroy bacteria and have been shown to be safe to use on human and mammalian skin, yet cause significant disruption to bacterial systems, resulting in broad-spectrum bacterial cell damage and death. KYOWAVE as s novel light device has been tested and shown to kill bacteria.

Fully charged Kyowave delivers approx 57.35W/m2 at a distance of 1cm. In Vivo studies have been carried out at the University of Surrey using Kyowave on methicillin resistant Staphlococcus aureus(MRSA) and Pseudomonas aeruginosa. Both were exposed to the light for between 15 and 30 mins on a paper disc placed 1cm away

Total bacterial killing

When tested total bacteria killing was observed against P. aeruginosa after 30 minutes of light exposure (A) and after 25 minutes against S. aureus (B), with a 5-log reduction in bacteria numbers compared to the non-treated controls.
