The house fly (_Musca domestica_) has a genome that could actually give scientists insight into pathogen immunity, helping humans live healthier lives, researchers write in the journal _Genome Biology_. And it’s all because of their, well, gross-factor. Since the house fly lives on animal and human waste, [according to _Science Daily_](http://www.sciencedaily.com/releases/2014/10/141014085142.htm), “\[t\]hey are an important species for scientific study because of their roles as waste decomposers and as carriers of over 100 human diseases, including typhoid, tuberculosis and worms.” Their immunity system genes can be studied to help humans be healthier in toxic and disease causing environments, the researchers add, and detoxification genes could help scientists find better ways to manage toxic environments. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3506185/those-pesky-house-flies-may-actually-improve-our-health/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3506185/those-pesky-house-flies-may-actually-improve-our-health/"},"headline":"Those Pesky House Flies May Actually Improve Our Health","datePublished":"2014-10-14T15:06:24.000Z","dateModified":"2026-02-21T10:46:24.868Z","description":"According to new research in 'Genome Biology'","url":"https://time.com/3506185/those-pesky-house-flies-may-actually-improve-our-health/","keywords":["Research","animals","Studies","Science topic"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt81a4802c82c3ef72/698760a68e06013a24457b11/481592081.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Laura Stampler","jobTitle":null,"url":"https://time.com/author/laura-stampler/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt81a4802c82c3ef72/698760a68e06013a24457b11/481592081.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"House Fly","caption":"House Fly","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3506185/those-pesky-house-flies-may-actually-improve-our-health/","name":"Those Pesky House Flies May Actually Improve Our Health"}}]}] ```
