“…Of these, 6.7% were in the healthy group and 90.9% in the group of animals with asthma. Similarly, fungal concentration in tracheal lavage samples in CFU/mL differed significantly between groups (P < 0.001), averaging 5 CFU/mL in healthy animals and 310 CFU/mL in animals with asthma (Xavier et al, 2014).…”

Asthma is a chronic respiratory disease that can occur in horses of different breeds and ages. While its occurrence has been reported in many countries, its occurrence across Brazil is unclear. This review aimed to gather information about equine asthma from studies performed in Brazil by different groups and investigate a variety of horse populations. Articles published in peer-reviewed scientific journals, as well as information contained in dissertations and theses, were searched on PubMed, SciELO, Google Scholar, and the Brazilian government catalog of dissertations and theses. Fifteen studies were included in this review, and according to the published information, the authors identified equine asthma using clinical signs, endoscopic findings, and/or cytological examination of tracheal wash and/or bronchoalveolar lavage fluid. Studies have investigated horses of different breeds and activities (racehorses, police horses, riding horses, Crioulos horses, and others) and were performed in different regions with diverse climatic conditions. On the previous observed studies, the occurrence varied from 14.0% to 60.0%, with a mean occurrence of 24% for severe asthma. Other studies must be performed to further understand the occurrence of equine asthma in Brazil, according to different climatic regions.

Exposure to bioaerosols associated with horse stable indoor environment and their health effects on people and horses has recently become of particular interest. Moreover, increasing frequency of recurrent airway disease (RAO) among horses made it necessary to search for the most probable causal agents of this disease and methods of their eradication. The study was conducted in two horse stables in southern Poland (Kraków and Tarnów). Particulate matter (PM2.5, PM4, and PM10) concentrations were determined photometrically, the concentration of fungal aerosol was determined by a six-stage impactor, and next generation sequencing (NGS) was used to determine fungal community composition in one of these stables. The highest PM concentrations were observed in Tarnów, but fungal aerosol levels were higher in the Kraków stable. Based on the NGS results, the three most prevalent fungal species were Wallemia sebi, Aspergillus penicillioides, and Epicoccum nigrum, all highly allergenic and potentially involved in the occurrence of RAO in horses. Spores of the detected fungi can penetrate deeply into the respiratory system. Therefore, this study suggests that examinations of particulate matter and fungal aerosol concentrations, along with species composition assessment, should be regularly conducted in horse stables.
