Skin Disorders
Mites  *  Ringworm Munge  *  Wool Break
 

 
Alopecia - This is the term used for bald spots. The most common is the bare spot on the bridge  of the nose.  More common in summer months, it can be caused by fly irritation and rubbing.   For this problem, some owners have found improvement by applying Conofite, Vitamin E Oil, Vaseline, or Preparation H to the area.  The wool on the bridge of the nose normally grows back in winter months if not before.

If the area with hair loss is crusty, flaky, thickened or reddened,  one may have to suspect ringworm, mange, mites, a type of fungus, rain scald, or zinc responsive skin disease (sometimes called elephant skin).  When the wool is coming out or breaking off, but not leaving a bald spot, it  may be due to shedding or a wool break due to some  stress or illness.  Often this will occur when a llama goes to a new home or births a cria for the first time. 

Mites
This Case Has Not Been Clinically Diagnosed

Notes From Owner:  Began with loss of hair and then gradually the bald patches increased in size, thickly encrusted with a greyishness or sometimes simply reddish in color. In one or two areas the skin has cracked and bled.  The affected area, now extensive, is the inner thighs, now completely stripped of hair, and the anus region. It seems the front legs are beginning to be affected too. While this condition is unsightly and very disturbing to me, Maryann seems completely unaware of it. There is no apparent itching and none of the limping which would indicate soreness.  Her field here in southern England is poorly drained clay of neutral to acid soil. By avoiding over-stocking, we manage to keep all but the gate areas free of mud. Temperatures of late include nights below freezing, in case this is relevant. She lives with four male llamas - none of which show any sign of the problem.
Suggestions from other llama owners:
1.  One owner suggests that these pictures look just like a mite problem that he had on one of his animals.  Injectible Ivermectin or Dectomax should take care of mites.  A skin scraping from the outer edge of the area would determine if it was mites or a type of fungus.  He then treated it with good old fashioned lime sulfur spray.  He drenched the area well twice a day.
2.  Another owner suggests that this could also be a type of fungus.  This farm treats a skin fungus with a Betadine or Iodine Scrub and then follows up with applications of fungal shampoo or medications.  Sometimes fungal infections can be very very difficult to clear up.
3.  Another Owner:  I have been fighting the exact same thing on one of our older girls. I finally got a hold on it by bathing the affected areas with a copper based soap and treating with dectomax. I did a skin scraping and had no doubt it was mites!!!!  Watch your other animals closely, especially the young and old................it is highly contagious. I also used  Cylence on the whole herd.
4.  Another Owner:  My vet suggested using Bag Balm on the area.  It prevents the air from getting to the area and allows it to heal.

More Suspected Mites

These photos show the loss of wool on legs of llamas from mites.  These animals were treated with Dectomax, 1 cc per 100 lbs., and the bare areas stopped spreading.

Ringworm

These are photos of a spot of Ringworm on a llama's nose.  This case was clinically diagnosed by a skin culture.

     Ringworm is not actually a worm, but rather a type of fungi.  And the skin lesion is not always in the form of a ring.  This species of fungi are sometimes found as normal inhabitants of soil, however, it may also be found in contaminated pens.  Highly contagious, it is easily spread from animal to animal - but rarely to humans although it is a possibility. 

     Arthrospores, the infective element of this fungi, invade the hair shafts and the outer layer of skin resulting in hair loss and a crusty appearance.  It most often appears on the face, the legs, or the feet.
 
     The photo on the top left was first noticed on the side of the animal's nose.  The photo on the top right is a close up view.  The photo just to the left is the area after it was cleaned with Betadine and the crustiness removed.  It was then treated with an anti-fungal cream which took care of the problem immediately.  It takes a few weeks before you notice the hair starting to grow back on the area.  Wash hands thoroughly after administering treatment.

Treatment:  Topically, treat with tincture of iodine or straight nolvasan.  Apply with a cotton swab so as not to get any in eyes etc - can be very irritating. Apply every other day for 1 week.




 

This photo below is of Ringworm on the side of the face just above the mouth.  The crusty spot was removed and it was treated topically with Iodine.  A follow up treatment of Confite, an anti-fungal ointment, was done a couple of days later.

Another Suspected Ringworm Case
 


 


Munge

Munge appears as a crusty crud or pustular dermatitis generally around the mouth and nose. Lesions may include thickening and cracking of the skin at the corners of the mouth and crusty scales on the lips and nose. Most cases of munge appear in animals 6 mo to 2 years of age. Cause is unknown. It may be the result of a bacterial infection, fungal infection or constant contact with an irritant like wet grass.  Skins scrapings should be done to rule out ringworm or mites. Suggested treatment is iodine scrubs. Some owners have had success with the use of a mixture called Witches Brew.
