The objective of this study was to confirm the practical value of high-resolution respirometry (HRR) applied to biopsies to determine, in horses, the level of training, their athletic ability and for the early detection of muscular dysfunction. Materials and methods – The muscle mitochondrial respiration was determined by HRR in 20 endurance horses and 10 trotters sampled at the triceps brachii at different stages of their training. Results – Training increases mitochondrial respiration, in addition, the best performers had the highest rate of respiration. A trotter had abnormally low levels of muscle mitochondrial respiration for its level of training. This horse has presented several episodes of rhabdomyolysis during its racing season. Discussion – The biopsy is easily achievable by the attending veterinarian. This study shows that the athletic ability of horses is closely linked to respiratory muscle function, and suggests the value of HRR for performance prediction. In addition, the RHR has the ability to demonstrate mitochondrial dysfunction potentially responsible for exercise-induced rhabdomyolysis. [less ▲]

Equine gammaherpesviruses (cEHV) have been widely studied over the past 45 years and many isolates have been characterised. Despite this, the diagnosis of cEHV infection remains difficult to establish as its clinical manifestations lack specificity, ranging from mild respiratory signs in a small number of animals to outbreaks in large groups of young horses. This review focuses on the epidemiology, pathogenesis, clinical manifestations and diagnosis of equine herpesvirus (EHV)-2 and -5 infections, as well as on the genetic variation of these viruses. Study of these variations has resulted in hypotheses relating to viral re-infection and re-activation. Interestingly, the viruses were found to contain genetic sequences identical to those of eukaryotic cells which are considered central to the development of viral latency through interfering with host immune and inflammatory responses. Future molecular biological studies will further elucidate the virulence mechanisms of these equine pathogens [less ▲]

Lower airway inflammation is a frequent cause of poor-performance in hors e s .An association between inflammation and bacterial isolation in tracheal wash fluid has previously been found ; bacterial counts were neve rtheless not defined.The aims of this study were to qualitatively and quantitatively compare tracheal bacterial flora of French Trotters with tracheal inflammation (SIT) and control horses (CTL), and evaluate association between endoscopic, cytological and microbiological evaluation of the trachea. Neutrophil percentage in tracheal wash was significantly different between groups whereas tracheal mucus accumulation was not. No significant difference was found between groups for neither percentage of respectively sterile samples or percentage pathogenic bacteria being isolated. Bacterial counts in SIT group were however 10 to 200 times higher than in the CTL group.This study suggests that isolation of pathogenic bacteria alone do not allow estimation of the level of airway inflammation; whereas severe tracheal inflammation may be present in absence of any bacteriological infection [less ▲]

This paper analyses the usefulness of arterial blood gas analysis (ABG) as ancillary test during the examination of the poor performance horse. The principle of the measurement of the gas tensions and the methodological rules to be respected are presented. The functional troubles inducing impairments of pulmonary gas exchanges are described. Several papers reporting the effect of upper and lower airway dysfunction on ABG have been published. On the basis on this scientific information, the usefulness and the limits of the ABG analyses as ancillary test in the examination of the poor performer are presented and discussed [less ▲]

The objectives of this study were to estimate the prevalence and the potential role of equine herpesviruses (EHVs) detection in both bronchoalveolar lavage (BAL) and tracheal wash (TW). The population included a control group (CTL; 37 TW and 25 BAL) and a pathological group (PAT; 259 TW and 387 BAL), including horses either suffering from respiratory diseases including syndrome of tracheal inflammation, inflammatory airway disease, recurrent airway obstruction, or submitted to respiratory investigation because of exercise intolerance or poor performance. Each respiratory liquid was submitted to a standardised cytological analysis, mentioning the morphological abnormalities of exfoliated epithelial cells (ECAb) and ciliocytophthoria (CCPh) as markers of potential viral infection, as well as PCR assays including a consensus PCR and virus-specific PCR for both equine alphaherpesviruses (EHV-1; EHV-4) and gammaherpesviruses (EHV-2; EHV-5). The EHV infections were more prevalent in the TW of PAT group (P = 0.004), with the highest prevalence being for EHV-2 (P = 0.006). The EHV detection in BALs was not significantly different between groups. The EHVs detection in TW was correlated to the polymorphonuclear neutrophil (PMN) counts in the respiratory liquid but not with CCPh or ECAb. CCPh or ECAb were associated with both consensus PCR and EHV-2 and EHV-5 virus-type PCR in the BAL only. The significant detection of EHVs in the TWof PAT group in association with the PMN increased counts could lead to further investigations about their putative role in equine syndrome of tracheal inflammation [less ▲]

Athletic ability of endurance horses is intimately linked to muscle oxidative capacity. Microbiopsies of triceps brachii (TB) and gluteus medius (GM) were collected before and after 10 weeks of training in 7 endurance horses to assess the feasibility of studying training effect with the use of microbiopsies. Oxygen consumption of permeabilized fibers was evaluated by high resolution respirometry (HRR) with a titration protocol that defines the activity of the mitochondrial complexes. Differences among muscles before and after training as well as training effect were assessed by Wilcoxon matched pairs test (P<0.05). No complications occurred following microbiopsies in any horse. The in situ oxidative capacity of the TB and GM increased with training. No difference was found between the TB and GM when one horse was excluded from the statistical analysis. Indeed, this horse showed signs of exercise intolerance before sampling (after the training period) which were associated to a low rate of respiration in GM but not in TB. Results of this study showed that HRR may be used to follow training effect and suggest that metabolic impairment might be detected with HRR. [less ▲]

This study aimed at testing the feasibility of using the Cosmed K4 b2® portable telemetric gas analysis system to record metabolic parameters in ridden exercising horses. Adaptation of the Cosmed K4 b2® to horses’ specificities included the design of an airtight face-mask (Equimask®) adapted to a hackamore bridle to allow ridding the horse. The portable system enables the recording of tidal volume (VT), respiratory rate (RR), minute expired volume (VE), pulmonary oxygen uptake (VO2), carbon dioxide delivery (VCO2), heart rate (HR) and speed. Four saddle horses equipped with the system completed 3 treadmill tests (TT1 to TT3) and 1 field test (FT) consisting of galloping phases at incremental speeds. Horses were sampled for blood lactate (LA) during the tests. The successive treadmill tests showed the influence of stress on measurements: with horses becoming accustomed to treadmill, LA and HR were reduced between TT1 and TT3. As VO2 is related to cardiovascular function, influence of stress resulted in higher VO2 in TT1 vs. TT3. The VO2 reached at maximal speed during treadmill tests was lower than the expected maximal aerobic power (VO2max) for trained saddle horses. During FT, the VO2 reached at the final gallop was lower than the VO2 recorded during any of the treadmill tests thus reflecting the increasing difficulty to reach VO2max with ridden horses in field conditions. This study demonstrated that cardiorespiratory parameters may be obtained in ridden horses during a field trial and opens new perspectives in the follow-up of sport horses in real field conditions.
