Epizootic lymphangitis can resemble [[Glanders (Farcy) - Donkey|glanders]] caused by [[Pseudomonas aeruginosa and Burkholderia species#Burkholderia mallei|''Burkholderia mallei'']], ulcerative lymphangitis caused by [[Corynebacterium species#Corynebacterium pseudotuberculosis|''Corynebacterium pseudotuberculosis'']] or sporotrichosis caused by [[Subcutaneous Mycoses#Sporotrichosis|Sporothrix schenckii]]. In some parts of Egypt '''lacrimal histoplasmosis''' is a common manifestation of the infection (Saleh, 1989; Heragy, 2003). The condition starts with slight conjunctivitis and epiphora. This progresses to blepharospasm and photophobia as the eyelids and lacrimal sac become severely inflamed. Chronic conditions may present with purulent nasal discharge from the affected nostril and fistulation of the lacrimal duct.
