Egg yolk peritonitis is commonly diagnosed in laying hens when yolk from a developing egg or an incompletely shelled or ruptured egg is deposited within the body cavity rather than passing normally from the ovary, into the oviduct, and then out of the body as a fully shelled egg. The yolk material that is released into the coelomic cavity causes inflammation of the peritoneum and typically the development of fluid within the coelom. Affected birds will often stop laying, become less active, have distended abdomens, and have difficulty breathing. Veterinarians diagnose egg yolk peritonitis through a combination of physical examination findings, blood testing, and imaging with radiographs or ultrasound. Treatment is supportive, with supplemental feeding, anti-inflammatory medication, antibiotics, hormones to prevent further egg laying. With more advanced cases, oxygen therapy and fluid drainage from the abdomen may be necessary.

Ehrlichiosis is a tick-borne bacterial (Ehrlichia) infection spread by the brown dog tick found in many areas of North America. There appear to be three stages of disease: acute, sub-clinical, and chronic or clinical. Abnormal findings on initial lab work include thrombocytopenia, anemia, hyperglobulinemia, and proteinuria. In-clinic ELISA tests can be used to screen for exposure but will be negative if the infection is new. Blood can be sent for PCR testing to demonstrate infection and to determine the species of Ehrlichia. Prevention includes minimizing exposure to ticks and use of tick prevention medication regularly.

An electrocardiogram (ECG, EKG) is a test that is used to assess the heart. More specifically, an ECG measures the transmission of an electrical impulse through the heart. This test is not painful and is typically performed as an outpatient procedure. Analyzing the electrical impulses produced as the heart beats can help identify a number of different abnormalities within the heart.

Endocarditis is an infection of a heart valve, most often affecting the mitral or aortic valve. It can arise any time that bacteria enter the bloodstream, though it is more common when the heart valve has already been damaged for some other reason. The clinical signs of endocarditis are often nonspecific in the early stages, but may progress to include signs of heart failure later in the course of the disease. The diagnosis and treatment of endocarditis can present a challenge, requiring multiple tests and prolonged courses of antibiotic therapy.

Congestive Heart Failure in Dogs
La insuficiencia cardiaca es la incapacidad del corazón para mantener un aporte de sangre suficiente para satisfacer las necesidades del organismo. Una insuficiencia cardiaca suele reflejar un fallo del músculo cardiaco (insuficiencia miocárdica), que puede afectar al ventrículo izquierdo o al derecho.
