    • Granulomatous lesion in wall of ileum Bilateral purulenthemorrhagic nasal discharge
    • Bilateral purulent nasal Bilateral mucopurulent )discharge )with blood nasal discharge Ruptured pharyngeal lymph nodeMassive pharyngeal and Bastered Strangles, pharyngeal submandibular swelling, discharging abscesses, lymphadenopathy weight loss, abducted elbow associated with dyspnea and ventral edema
    • Bastered Strangles, extensive Massive pulmonary pharyngeal and abscess with submandibular multiple lymphadenopathy compartments and thick fibrous reaction Endoscopic view of pharynx difference in discharge from guttural pouches indicating time difference to rupture of pharyngeal abscessBastered Strangles, in guttural pouches.hypopyon with Discharge from leftminimal corneal pouch is older thaninvolvement right

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

    • Miliary abscesses on Large numbers of abscesses the lung lesions in lung parenchyma Foal presented with severe diarrhea. Large numbers of abscesses in mesentery and lymph nodes of colon and cecum
    • Neonatal septicemia, Five day old foal with sign ofgeneralized petechiation of neonatal septicemia, aqueousall body surfaces including flare )due to inflammatory debris .this pleural surface 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
    • Caused by Corynebacterium ovis Chronic form, Corded lymphatic Lesion affecting the extensive vessels and lower hind limbs of fibrosis and purulent discharge foal above the hock. Itdistal edema of from ulcerated site is unusual to find hind leg )arrow(. Chronic lesions above the hock thickening and or on the front limbs exudate over distal parts of limb
    • Lesion restricted to saddle contact area. Very painful lesion with exudates Lesion had been present with littlechange for several years
    • Extensive hair Extensive deep loss leaving exudative hyperkeratotic dermatitis with linear scabs and cracking and skin denuded of thickening of skin hair on palmar pastern of white footLoss of hair follows water run off pattern Extensive hair loss followed minor remaining hair is matted with exudate, grooming effort, leaving denuded some areas of hypopigmentation over skin with minimal scraping and no gluteal region apparent exudates
    • Hair matted in a tesselated Pale glistening surface with pattern purulent exudate found under matted hair Hair plucked from a case Paint brush effect withshowing paint brush effect denudation of hair. No purulent exudate, skin surface very dry
    • Chest abscesses )pigeon breast / Wyoming strangles(Corynebacterium equi

Several horses sharing saddlery developed an almost identical syndrome over 2 weeks. Lesion approximately 14 days post infection
