Profuse dark diarrhea over wall of stable. Diarrhea contained blood and
shreds of intestinal mucosa. Profuse diarrhea, often with blood
and shreds of mucosa
Very limited area of distal jejunum and proximal ileum affected with hemorrhagic
inflammation
Extensive severe inflammation of jejunum which is not distended.
Proximal distension (portion held) and normal large colon
Well defined patches of compromised small intestinal wall (arrow)
Granulomatous lesion in wall of ileum
Bilateral purulent hemorrhagic nasal
discharge
Bilateral purulent nasal discharge (with blood)
Bilateral mucopurulent nasal discharge
Massive pharyngeal and submandibular
lymphadenopathy
Ruptured pharyngeal lymph
nodeBastered Strangles, pharyngeal
swelling, discharging abscesses, weight loss, abducted elbow
associated with dyspnea and ventral edema
Bastered Strangles, extensive pulmonary abscess with multiple compartments and thick fibrous reaction
Endoscopic view of pharynx difference in discharge from guttural pouches indicating time difference to rupture of pharyngeal abscess in guttural pouches. Discharge from left pouch is older than right
Massive pharyngeal and submandibular lymphadenopathy
Bastered Strangles, hypopyon with minimal corneal involvement
Swelling ( non tympanic) below tendon of insertion of sternocephalicus m.
Endoscopic view, chondroids (inspissated and tumbled purulent material. Generalized diverticulitis with loss of detailed structure such as blood vessels on mucosa
Endoscopic view, caseated, purulent material on floor of medial compartment. Some loss of surface detail
Endoscopic view, very liquid contents, generalized diverticulitis with loss of normally obvious detalid anatomical features such as blood vessels and nerves
Endoscopic view, purulent discharge from pharyngeal ostium of left pouch (arrow). Marked dorsal pharyngeal compression.
Bilateral hemorrhagic nasal discharge
Bilateral venous epistaxis
Sharply demarcated edema of fore limb at level of elbow
(arrow) .
Petechial hemorrhages in vaginal m.m
Chains of ulcerated lymphatic nodules
Chains of ulcerated, discharging nodules following lymphatic
versals
Bilateral purulent hemorrhagic nasal discharge (scanty) with fetid odor
Tongue withdrawal absent
Tail (hand pump) head elevation. Horse showed stiff and stilted gait
Prolapsed third eye lid and enophthalmos in response to sudden noise and when face is tapped with a finger(
Fixed, alert facial expression, erect ears, prolapsed third eye lid, nostrils drawn open and tense mouth
Opisthotonus and extensor rigidity of neck, limbs, trunk and tail
Miliary abscesses on the lung
Large numbers of abscesses lesions in lung parenchyma
Foal presented with severe diarrhea. Large numbers of abscesses in mesentery and lymph nodes of colon and cecum
Neonatal septicemia, generalized petechiation of all body surfaces including
this pleural surface.
Five day old foal with sign of neonatal septicemia, aqueous
flare (due to inflammatory debris in aqueous humor ) , hyphema
(blood in anterior chamber). Muddy appearance of iris and
miosis
Multiple pyaemic abscesses encountered in a 10 day old foal with septicemia
Septicemic form, edematous swelling of neck and throat.
Chronic form, extensive
fibrosis and distal edema of
hind leg
Corded lymphatic vessels and
purulent discharge from ulcerated site
(arrow). Chronic thickening and
exudate over distal parts of limb
Lesion affecting the lower hind limbs of
foal above the hock. It is unusual to find
lesions above the hock or on the front limbs
Caused by Corynebacterium ovis
Lesion had been present with little
change for several years
Lesion restricted to saddle contact area. Very painful
lesion with exudates
Extensive hair loss followed minor grooming effort, leaving denuded skin with minimal scraping and no
apparent exudates
Loss of hair follows water run off pattern remaining hair is matted with exudate, some areas of hypopigmentation over
gluteal region
Extensive deep exudative dermatitis with cracking and thickening of skin on palmar pastern of white foot
Extensive hair loss leaving hyperkeratotic linear scabs and skin denuded of hair
Hair matted in a tesselated pattern
Hair plucked from a case showing paint brush effect
Paint brush effect with denudation of hair. No purulent exudate, skin
surface very dry
Pale glistening surface with purulent exudate found
under matted hair
Chest abscesses (pigeon breast / Wyoming strangles) Corynebacterium equi
Highly painful necrotic changes in skin of coronet
(arrow) .
Enlarged gland, mare lame, obvious engorgement of
transthoracic vein (arrow) Gland was hot, painful, and had stringy milk without
clots. Edema above gland
Enlarged gland with fibrous induration
Raised hair patches of very early lesions (10 days post
infection)
Obvious heavy encrustation with minimal exudation
Distribution of lesions corresponding with girth position. Several horses sharing saddlery developed an almost identical syndrome over 2 weeks. Lesion approximately 14 days post infection
Microsporum gypseum transmitted by insect bite, note: location and
pattern of lesions correspond with biting site of insect, hair loss not complete and scabs less easily
removed
Hair loss leaves silvery grey glistening skin
which heals within 4-5 days. Border of lesion
poorly demarcated
Multiple nodules and crusted plaques over the shoulder
Lesion on third eye lid and/ or at the lacrimal puncta often
have an aggressive neoplastic appearance
A mild, self limiting conjunctivitis with marked epiphora was present in this case
with the typically more severe lesions characteristic of the disease on the eye lids
and within the naso lacrimal apparatus. Marked tear dermatitis is often present
down the sides of the face.
