Erysipeloid

speak

Erysipeloid is a type of bacterial infection caused by Erysipelothrix rhusiopathiae, which is typically found on the skin and mucous membranes of fish, poultry, and other animals. In humans, erysipeloid is usually a mild, self-limiting infection that occurs when an open wound or cut comes into contact with contaminated animal tissue or products. The symptoms, which may develop 1-7 days after exposure, include a red, painful, swollen area, fever, and swollen lymph nodes. Erysipeloid is often treated with antibiotics and antibiotics-resistant strains have been reported.

Erysipelothrix

The bacteria Erysipelothrix rhusiopathiae is commonly found on the skin and mucous membranes of animals, particularly pigs, horses, and cattle. Humans can contract the infection through cuts or abrasions on the skin that come into contact with contaminated animal tissues or products, such as hides, bones, or organs. Erysipeloid may cause symptoms including swelling, inflammation, redness, and fever, but it is generally not life-threatening and can be treated with antibiotics.

Erysipelous

speak

Erysipelous refers to a skin infection caused by the bacterium Erysipelothrix rhusiopathiae, which is often acquired through contact with infected animals, particularly pigs and birds. The infection usually starts as a red, painful rash on the hands or feet, and can spread to other parts of the body if left untreated.

Erysiphaceae

Erythroblast

speak

Erythroblast is a term used in medicine, specifically in hematology. It refers to an immature red blood cell that is still in the process of developing in the bone marrow. Erythroblasts are the precursors of mature red blood cells, also known as erythrocytes. They are an essential part of the production process of red blood cells, which carry oxygen throughout the body.

Erythroblastaemia

speak

Erythroblastaemia is a medical term that refers to an abnormality in the development of red blood cells, particularly in the production of immature red blood cells called erythroblasts in the bone marrow. It can be caused by various factors such as vitamin deficiencies, infections, or certain medications, and can lead to anaemia and other hematological disorders.

Erythroblastemia

speak

Erythroblastemia is a medical term that refers to an excess of immature red blood cells (erythroblasts) in the blood. This condition can occur due to various factors such as blood disorders, infections, or underlying medical conditions. It is often indicative of bone marrow thrombocytopenia, a disorder where the bone marrow produces too few platelets.

Erythroblastopenia

speak

Erythroblastopenia is a medical term that refers to a condition characterized by a decrease in the production of red blood cells in the bone marrow, resulting in a low red blood cell count or anemia.

Erythroblastosis

speak

Erythroblastosis is a medical condition characterized by the presence of immature red blood cells (erythroblasts) in the blood. It occurs when there is an increased production of these immature cells, often as a result of damage to the liver or spleen, or due to certain blood disorders. In some cases, erythroblastosis can be caused by Rh incompatibility between a mother and her fetus during pregnancy, leading to hemolytic disease of the newborn.

Erythroblasts

speak

Erythroblasts are immature red blood cells that are found in the bone marrow and play a crucial role in the production of mature red blood cells (erythrocytes). They are an essential part of the process of hemopoiesis, the formation of blood cells in the bone marrow. Erythroblasts are produced from stem cells and undergo a process of differentiation to become mature red blood cells, which carry oxygen throughout the body.

Erythrochroic

speak

Erythrochroic refers to a change in color or a reddening of the skin, particularly in response to heat, cold, or other forms of physical stimulation.
