The head may be affected, but this is typically only in young children. [2] The itch is often worse at night. [2] Scratching may cause skin breakdown and an additional bacterial infection in the skin. [2] Scabies is caused by infection with the female mite Sarcoptes scabiei var. hominis, an ectoparasite. [3]
Sarcoptes scabiei (/sɑːrˈkɒptiːz skeɪˈbiːaɪ/ Traditional English pronunciation of Latin) or the itch mite is a parasitic mite found in all parts of the world that burrows into skin and causes scabies. Humans become infested by Sarcoptes scabiei var. hominis; [1] other mammals can be
Autoeczematization (id reaction, auto sensitization) is an eczematous reaction to an infection with parasites, fungi, bacteria, or viruses. It is completely curable with the clearance of the original infection that caused it. The appearance varies depending on the cause. It always occurs some distance away from the original infection. (ICD-10 ...
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
[3] [6] They are everywhere and infection occurs after spores are either breathed in, come into contact with skin or enter the body through the skin such as via a cut, wound or injection. [3] Candida albicans is the most common cause of fungal infection in people, particularly as oral or vaginal thrush, often following taking antibiotics. [3]
Humans can be infected with many types of pathogens, including prions, viruses, bacteria, and fungi, causing symptoms like sneezing, coughing, fever, vomiting, and potentially lethal organ failure. While some symptoms are caused by the pathogenic infection, others are caused by the immune system's efforts to kill the pathogen, such as ...
Infection on the skin of the feet may cause athlete's foot and in the groin, jock itch. Involvement of the nails is termed onychomycosis . Animals including dogs and cats can also be affected by ringworm, and the disease can be transmitted between animals and humans, making it a zoonotic disease .
The disease is infectious and can be transmitted by humans, animals, or objects that harbor the fungus. The fungus can also exist in a carrier state on the scalp, without clinical symptomatology. Treatment of tinea capitis requires an oral antifungal agent ; griseofulvin is the most commonly used drug, but other newer antimycotic drugs, such as ...
