Recurrent airway obstruction, also known as broken wind, heaves, wind-broke horse, or sometimes by the term usually reserved for humans, chronic obstructive pulmonary disease or disorder (COPD) – it is a respiratory disease or chronic condition of horses involving an allergic bronchitis characterised by wheezing, coughing and laboured breathing.
In Horses, S. zooepidemicus is normal flora bacterium, but is opportunistic and therefore will infect wounds, the respiratory system, and uterine, if given the chance. In horses, which are most commonly infected, this bacterium causes an upper respiratory tract infection (along with the other symptoms).
Equine influenza is characterized by a very high rate of transmission among horses, and has a relatively short incubation time of one to three days. [6] Clinical signs of equine influenza include fever (up to 106 °F [41 °C]), nasal discharge, have a dry, hacking cough, depression, loss of appetite and weakness. [6]
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
Equine multinodular pulmonary fibrosis is a chronic lung disease of horses. There is evidence that the disease is caused by infection with a gammaherpesvirus , equine herpesvirus 5 . The disease affects usually adult horses reducing the ability to exercise as a result of the formation of nodular lesions in the lungs.
Fever of 102.5–105.0 °F (39.2–40.6 °C), frequent dry cough for several weeks, ‘drippy’ nose with discharge and secondary bacterial infection are some of the clinical signs of Equine influenza virus infection. isolation of influenza virus from nasopharyngeal and or large rise in antibody titer in equine-1 or 2 serum can be used as ...
An adult horse has an average rate of respiration at rest of 12 to 24 breaths per minute. [3] Young foals have higher resting respiratory rates than adult horses, usually 36 to 40 breaths per minute. [3] Heat and humidity can raise the respiration rate considerably, especially if the horse has a dark coat and is in the sun.
Horses with EMS will have an increased insulin response after they are given oral sugars, which will cause a subsequent rise in blood insulin levels, or hyperinsulinemia. Hyperinsulinemia results in decreased tissue sensitivity to insulin, or insulin resistance, especially by the skeletal muscle, liver and adipose tissue.
