Equine Thrush



Thrush is a degenerative condition of the Frog caused by anaerobic bacteria characterised by a grey/black necrotic material in the affected area.


Thrush affects the Medial/Lateral & Central Frog clefts


Thrush is caused by Unhygienic conditions where anaerobic bacteria can thrive, the bacteria Spherophorus Necrophorus is most commonly found.  The contribution factors to this are;

Unhygienic Conditions
Poor Stable management
Poor grazing
Unclean Feet
Prolong use of sole pack & pads
Irregular Shoeing or Trimming
Long term use of Heart Bars

Clinical Signs

The Clinical Signs of Thrush are

An Offensive odour
Black/Grey narcotic frog
Increase Moisture discharge
Atrophied Frog
Exposure of sensitive Structures
Sheared Heels ( in Sever long term cases )


Diagnosis is based on clinical finding



Veterinary treatment in not normally needed unless infection is sever.


Farriery Treatment is aimed at removing the cause and limiting the cultivation of the bacteria. This can be done by;

Improving Stable Management
Removing all necrotic materiel
Treating with anti-bacterial sprays and Powder 
Regular Trimming and shoring 


  The foot should be well trimmed and as clean as possible. With extra attention being paid to the frog clefts. The frog should then be scrubbed with an iodine solution and flushed with hydrogen Peroxide to kill any anaerobic infection.Finally the food should be cleaned and dried with regular use of a hoof pick and anti-bacterial sprays advised.The use of bar shoes and Sole Pack is also ill advised as they can create a low oxygen environment that advantageous for the growth of bacteria. 


A Good Prognosis can be given as long as there is no extensive damage to the underling sensitive structures.
