Photo of tongue of steer with one day old ruptured vesicle
Plate 1 - Tongue of steer with 1-day-old vesicle which ruptured when the tongue was drawn from the mouth.
Photo of steers upper gum and tongue with ruptured vesicles
Plate 2 - Steer with 2-day-old ruptured vesicle along upper gum and several 1-day-old unruptured vesicles on the tongue.
Photo of two day old ruptured vesicles on the tongue of steer
Plate 3 - Two-day-old ruptured vesicles on the tongue, lower gum and lower lip of a steer. Note sharp edges to ulcerated areas.
Photo of a further example of a ruptured lesion on the tongue of a steer
Plate 4 - A further example of 2-day-old lesions in the mouth of a steer. Again note sharp margins of lesions and red raw appearance of exposed dermis.
Photo of steers tongue with three day old lesions
Plate 5 - Tongue of steer with 3-day-old lesions. Sero-fibrinous exudation into the lesions has resulted in a loss of earlier red raw appearance and also sharpness of margination. Early granulation evident.
Photo of steers tongue with four day old lesions
Plate 6 - Same animal as in plate 5 with 4-day-old lesions. Note progressive loss of lesion margination and extensive fibrin infilling.
Photo of steers tongue with ten day old lesion
Plate 7 - Steer’s tongue with a 10-day-old lesion characterised by loss of papillae, indentation at the site of the lesion and fibrous tissue proliferation.
Photo of steers foot with two day old unruptured inter digital vesicle
Plate 8 - Foot of a steer with a 2-day-old unruptured vesicle in the inter-digital space.
Photo of steers foot with two day old unruptured inter digital vesicle Plate 9 - A different steer also with a 2-day-old inter-digital vesicle.
Photo of steers heel bulbs with unruptured two day old vesicles Plate 10 - The heel bulbs of a steer’s foot with unruptured 2-day-old vesicles.
Photo of steers foot with ruptured vesicle Plate 11 - The same foot as in Plate 10, 1 day later. The epithelium overlying the vesicle is friable and easily stripped off.
Photo of steers foot with five day old lesion Plate 12 - A 5-day-old lesion on a steer’s foot. Signs of early granulation are evident.
Photo of a steers foot with seven day old lesion Plate 13 - A 7-day-old lesion on a steer’s foot. Healing is progressing underneath the necrotic epithelium.
Photo of another example of a seven day old foot lesion Plate 14- Another example of a 7-day-old inter-digital foot lesion on a steer.
Photo of an eleven day old lesion on the heel bulb of a steer Plate 15 - An 11-day-old foot lesion on the heel bulb of a steer. Note healing and under-running of horn tissue.
Photo of one day old vesicles on a teat of a cow. Plate 16- One-day-old vesicles on the teat of a cow. Rupturing has not taken place but several vesicles have coalesced.
