WRITING a science editorial regarding new aspects of equine grass sickness (EGS) is challenging at a time when we are eagerly awaiting results from vaccination trials and ongoing research, trying to identify the cause of EGS and factors involved in aetiopathogenesis. Britain has remained the country most affected by this often fatal neurodegenerat...

An increased content of eosinophils in cerebrospinal fluid (CSF) and eosinophilic infiltration of brain tissue are observed in eosinophilic meningoencephalitis (EME). After exclusion of various infectious diseases and further known causes of EME in other species, the diagnosis idiopathic EME was made at necropsy in the case reported here. To the au...

The medical records of 28 horses with guttural pouch mycosis were reviewed. The most commonly observed clinical signs were nasal discharge, epistaxis, dysphagia and/or cough. All 28 horses had the disease unilaterally, however, in five of them, it had spread into the contralateral pouch via the mesial septum. Three horses were treated medically, 11...

Equine grass sickness (EGS) occurs mainly in Great Britain, but has once been reported in Hungary. The stud which was affected by EGS in 2001 had no new cases until 2009/10, when 11 of 60 and five of 12 one- to three-year-old colts died or were euthanased due to EGS. Following a few hours in the high-risk field during the winter of 2010/11 further...

The aim of this study was to determine the occurrence and frequency of a mutation in the gene coding for skeletal muscle glycogen synthase type 1 (GYS-1), which is the cause of equine polysaccharide storage myopathy (PSSM) type 1 in a population of 50 Haflingers. GYS-1 genotyping of 50 Haflingers was performed with a validated restriction fragment...

A 6-year-old 680-kg (1,496-lb) German Warmblood gelding was evaluated because of bilateral blepharospasm and head shaking. Moderate blepharospasm was evident bilaterally, and both eyes had hyperemic and edematous conjunctivas and lusterless corneas. For each eye, the Schirmer tear test value was only 7 mm/min. The horse's nasal mucosa was dry. Abno...

Poultry mites (Dermanyssus gallinae) have occasionally been reported to cause pruritic dermatitis not only in humans but also in horses. Diagnosis is based on history and evidence of mites in the environment. Because the mites only feed on the horse temporarily, demonstrating the D. gallinae in skin scrapings may be impossible. Case report A 19 yea...

Different diseases can cause headshaking in horses. Therefore an intensive work up is needed. But in 90 % of all cases no diagnosis can be reached. Headshaking can be caused by tooth problems, diseases of the guttural pouches, etc. but also photic headshakers or cases with allergic or vasomotor rhinitis are reported. Neuritis of the trigeminal nerv...
