Chaetoglobosin A (CHA) is produced by the mold Chaetomium globosum (CG).

Chaetoglobosin A (CHA) is one of the chaetoglobosin mycotoxins produced from the fungus Chaetomium globosum. Chaetomium globosum is the third most common indoor fungal contaminant of damp buildings. It has been isolated from several places such as soil, dung, feeds, foods, textiles, plywood, carpet, wallpaper and wet walls.

Inhalation of airborne spores and CHA from this fungus is known to produce respiratory as well as systemic infection in human beings. Case reports of infections include mild to severe illness, from sinusitis, onychomycosis, and cutaneous infections to disseminated cerebral disease, pneumonia and keratitis. Relatively low levels of CHA have been shown to be lethal to various tissue culture cell lines and it is thought that CHA is highly toxigenic, even at minimal doses.

Chaetomium globosum is a globally distributed hydrophilic mold commonly found in water-damaged buildings and various organic materials. It is recognized as a significant allergen linked to respiratory diseases, with studies showing sensitization rates of around 7% among atopic patients in regions like West Virginia and Poland. While it infrequently causes infections, particularly in immunocompromised individuals, its potential for producing mycotoxins raises health concerns. The mold's presence in damp environments contributes to poor indoor air quality and an increased risk of respiratory symptoms, including asthma. Preventing moisture accumulation and addressing water damage are essential strategies for minimizing exposure to this mold and its associated health risks.

Charcot-Leyden crystals are formed from the breakdown of immune cells, especially eosinophils, and may be seen in the stool of patients with parasitic diseases. The crystals are indicative of immune response and can sometimes be seen in association with non-parasitic infection or inflammation.

Chenodeoxycholic acid (CDCA), also known as chenodiol, usually conjugates with either glycine or taurine. It acts as a detergent to solubilize fats for intestinal absorption and is reabsorbed by the small intestine. It is used as cholagogue, a choleretic laxative, and to prevent or dissolve gallstones.

Elevated antibody levels can be clinically significant — while the antibodies themselves don’t destroy anything, they do trigger an inflammatory response that can cause significant destruction of tissue and resulting symptoms. This response is not necessarily dependent on antibody levels. However, an equivocal result may mean you are just beginning to exhibit an immune reaction, so this is an important time to take measures to support the body in damping immune reactivity.

Chia seeds (Salvia hispanica), also called Salba chia or Mexican chia, are the edible seeds of a flowering plant from the mint family. Native to Mexico and Guatemala, the seeds have a long history. They were a vital crop in ancient Aztec and Mesoamerican cultures. The seeds had medicinal applications and made up an important part of the peoples’ diets.

Today, chia grows commercially in many countries including Mexico, Guatemala, Peru, Argentina, Australia, and the United States. The seeds are widely recognized as a nutrient-dense addition to healthy diets.

Doctors recommend two doses of the chickenpox vaccine for children and unvaccinated individuals as the best protection against chickenpox, with most vaccinated people being protected for life. The vaccine is highly effective, preventing nearly all severe cases and resulting in milder symptoms for breakthrough cases. Children should receive doses at 12-15 months and 4-6 years, while older individuals should get two doses 28 days apart. Post-exposure vaccination can prevent or lessen the severity of the disease. Vaccination is crucial for at-risk groups like healthcare professionals, caregivers, and those in communal settings. Some individuals, such as those with immune system issues or who are pregnant, should consult a healthcare provider before getting vaccinated. The chickenpox vaccine is safe, effective, and has significantly reduced chickenpox cases, hospitalizations, and deaths since its introduction.

Chilomastix mesnili is a nonpathogenic flagellate that is often described as a commensal organism in the human gastrointestinal tract.

The bacteria Chlamydia pneumoniae is spread by airborne droplets and infects the mucous membranes of the respiratory tract. These infections can be the cause of pharyngitis, laryngitis and sinusitis. A dry, hacking cough is the most common symptom of these infections. Not everyone who has mycoplasma and chlamydia in their nasopharynx gets sick - it depends on the body's resistance, but they can still infect others.

Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI) worldwide. It manifests primarily as urethritis in males and endocervicitis in females.

Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma.
