“…Potassium iodide (KI) is commonly used in the treatment of fungal infections in horses, including those caused by aspergillus species (Crothers et al, 2009; Randleff‐Rasmussen et al, 2017; Robinson et al, 2007; Schwarz et al, 2009). Its mechanism of action is unclear but is thought to be due to the enhancement of specific immunoprotection mechanisms (Hassan & Keen, 2012).…”

SummaryA 9‐month‐old Thoroughbred colt was presented to the University College Dublin Veterinary Hospital for investigation of suspected neck pain. Clinical signs included severe dullness, bilateral mucopurulent nasal discharge, ptosis of the right eyelid, reduced range of motion of the neck and ataxia. Endoscopy of the medial compartment of both guttural pouches showed fungal‐like plaques, from which Aspergillus was cultured. Laser salpingopharyngeal fistulation was performed under standing sedation and the colt received treatment with oral potassium iodide. The colt developed bacteraemia post‐operatively which resolved after antimicrobial treatment. Serial endoscopic evaluation of the guttural pouches showed complete resolution of fungal plaques 4 months post‐operatively. Minimal neurologic deficits remained 6 months post‐operatively. This report highlights the importance of considering guttural pouch mycosis in young horses and those presenting with reduced range of neck motion and neck pain. It offers support for the use of salpingopharyngostomy as an effective treatment method for guttural pouch mycosis and documents its use in the case of bilateral disease confirmed by fungal culture. It also documents the recovery of a horse from GPM with associated severe neurological signs.

“…To summarise, the histopathological description, without granular lesions nor fungal invasion, is quite atypical for a fungus‐induced mycetoma, otherwise very rare in horses and frequently observed in cutaneous or subcutaneous tissues (Randleff‐Rasmussen et al . ). Histological examination might have been compared to aspergillosis granuloma in the mediastinum presenting with septated hyphae and Aspergillus ‐positive cultures that have been reported (Moore et al .…”

“…In the case reported here, the affected pony had concurrent pars pituitary intermedia dysfunction (PPID), which has been linked anecdotally to higher incidence of secondary infections (McFarlane ) and increased severity of fungal (Randleff‐Rasmussen et al . ) and parasitic disease (McFarlane et al . ; Raftery et al .…”

Mycobacterial infections in equids: Clinical characteristics and diagnostic techniques

Summary Mycobacterial infections in equids are relatively rare but the case report (Charlesworth 2017) detailed in this issue highlights that Mycobacterium bovis infections may still result in clinical signs in this incidental host and have zoonotic potential. Most reported cases of M. bovis in horses have a protracted disease course, with features including pyrexia, weight loss and oedema with a nonspecific inflammatory profile. As such, the clinical features of disease overlap with conditions such as neoplasia, peritonitis, protein‐losing enteropathies and bacterial infections including Rhodococcus equi and Lawsonia intracellularis. In this clinical satellite article, mycobacterial infections in equids are considered in terms of incidence and mode of transmission, key clinical features and perhaps most importantly, in terms of the diagnostic techniques that can be used in order to reach a definitive (ante mortem) diagnosis. The major zoonotic risk to veterinary personnel is likely to occur at the time of post‐mortem examination of infected horses, and awareness of these potential risks remains of the utmost importance.
