Chigger
Aka: Chigger, Chigger Bite, Mites, Harvest Bug, Red Bug, Trombicula, Summer Penile Syndrome- See also
- Pathophysiology
- Mites
- Chiggers
- Six-legged larval form of mites (appear as tiny red dots on skin)
- Responsible for Human Bites and vector for disease
- Chiggers crawl onto skin when host sits or lies on lawn or grass (appear as tiny red specks)
- Move into constrictive clothing where they bite
- Associated Conditions: Chigger as vector of disease
- Rickettsial Pox (Rickettsia akari)
- Scrub Typhus (outside U.S.)
- Symptoms
- Pruritic welts along constrictive clothing lines (waist band or sock line)
- Signs
- Allergic Reaction to Chigger Bite Saliva
- Large welt forms at site of Chigger Bite
- Distribution of bite sites
- Occluded areas (e.g. beneath waistband, belt line or sock line)
- Intertriginous areas (e.g. axilla)
- Penis may be affected (severe in some cases)
- May be known as Summer Penile Syndrome

Mites (C0026231) |
|
---|---|
Definition (MSH) | Any arthropod of the subclass ACARI except the TICKS. They are minute animals related to the spiders, usually having transparent or semitransparent bodies. They may be parasitic on humans and domestic animals, producing various irritations of the skin (MITE INFESTATIONS). Many mite species are important to human and veterinary medicine as both parasite and vector. Mites also infest plants. |

Chiggers (C0041171) |
|
---|---|
Definition (MSH) | Family of MITES in the superfamily Trombiculoidea, suborder Prostigmata, which attack humans and other vertebrates, causing DERMATITIS and severe allergic reactions. Chiggers, red bugs, and harvest mites commonly refer to the larval stage of Trombiculid mites, the only parasitic stage of the mite's life cycle. |

Trombicula (C0949450) |
|
---|---|
Definition (MSH) | A genus of MITES in the family TROMBICULIDAE, whose larvae cause and carry disease. The larvae attack humans and other vertebrates, causing dermatitis and severe allergic reactions. Adult forms do not bite. Species of the subgenera Leptotrombidium are the carriers of SCRUB TYPHUS. |
