Members of the genus Fusarium are ubiquitous fungi commonly found in soils and plants.

Fusarium proliferatum can be found on a wide host range as well as pathogenic on various agricultural crops. Fusarium proliferatum is a common pathogen infecting numerous crop plants and occuring in various climatic zones.

The marker "M010-IgE Stemphylium herbarum" refers to a specific immunoglobulin E (IgE) test used to detect sensitivity or allergic reactions to the mold Stemphylium herbarum. Stemphylium herbarum is a common fungus found in various environments, including outdoor locations such as soil, decaying plant material, and dead leaves. This mold species is prevalent during late summer and fall, particularly in temperate and humid climates. It can release spores into the air, which can be inhaled by individuals, potentially triggering an allergic response in susceptible people. The M010-IgE test measures the level of specific IgE antibodies in the blood that are directed against Stemphylium herbarum. Elevated levels of these antibodies indicate that the immune system is sensitized to this particular mold, meaning that exposure to it may cause allergic symptoms. Symptoms can range from mild to severe and may include sneezing, runny or stuffy nose, itchy eyes, coughing, wheezing, and other respiratory issues. In some cases, exposure can also aggravate asthma or other chronic respiratory conditions.

Together with Alternaria, Stemphylium is considered one of the most important mould allergens in the United States.

Rhizopus nigricans is a fungus commonly known as bread mold and is the most common species of Rhizopus. It is found on old food and in soils and even in children's sandboxes. The genus contains some 50 species and bread mold is sometimes confused with species of Mucor or other species of Rhizopus like Rhizopus oryzae. The spores, dispersed in hot dry weather, contain allergenic proteins with 31 distinct allergens, which can produce respiratory and nasal symptoms in concentration (chronic cough, dyspnea, chest tightness, chronic phlegm, snuffle, snizzle and allergic rhinitis). Food handling workers are particularly at risk if they are mold allergic.

It is a commonly encountered species in wet buildings. It is both a soil and leaf fungus.

Epicoccum can colonize an extremely wide variety of substrates. It lives in soil all over the world and is often associated with aging or decaying plant material. It is also a phytopathogen, causing leaf spot disease in many plants. It is an agent of food spoilage and has been known to develop on apples, cantaloupes, fresh vegetables, nuts and cereals, rice, wheat, maize, pecans, peanuts, cashews, soybean and frozen or cured meats. Interestingly Epicoccum can also colonize freshwater and marine environments and has been isolated from sediment, sponges, algae and other sea plants.

Aspergillus species are ubiquitous environmental molds that grow on organic matter and aerosolized conidia (conidia is a spore produced by various fungi at the tip of a specialized hypha).

Aspergillus is a genus of molds that includes several hundred species that grow in nutrient-depleted environments.

Humans inhale hundreds of conidia per day without adverse consequences, except for a small minority of people for whom infection with Aspergillus causes significant morbidity (the condition of suffering from a disease or medical condition). 

The clinical manifestations of aspergillosis are determined by the host immune response to exposure with the spectrum ranging from a simple allergic response to local lung disease with mycelial balls to catastrophic systemic Aspergillus infection.

Macrocytosis is a notable hematological condition characterized by the presence of abnormally large red blood cells (RBCs) in the bloodstream, a crucial marker in blood tests for various health assessments. This condition, detectable through a Complete Blood Count (CBC) test, typically indicates that the red blood cells are larger than their normal size, often measured by the Mean Corpuscular Volume (MCV).
