アボパルシン(Avoparcin)は、グラム陽性菌に効果のあるグリコペプチド系抗生物質である。鶏、豚、牛等の成長を促進するために、家畜飼料に添加される[1]。家禽の壊死性腸炎を防ぐためにも用いられる[1]

アボパルシンは、α-アボパルシンとβ-アボパルシンという2つの類似した化合物の混合物であり、これらは、β-アボパルシンに塩素が1つ余分に付加している点が異なっている。また、バンコマイシンとも構造が似ている。この類似性のため、動物にアボパルシンを広く用いることで、バンコマイシン耐性細菌の流行が懸念されている[2][3][4][5]

アボパルシンは、かつてオーストラリアやEUで用いられてきたが、現在はどちらでも許可されていない[1][6]。アメリカ合衆国では、認可されたことはない[7]

Pair of brogans, c. 1860–65. A brogan is a heavy, ankle-high shoe or boot. History Brogan-like shoes, called brogues (from Old Irish bróc meaning shoe), were made and worn in Ireland and Scotland as early as the 16th century, and the shoe type probably originated in Ireland.[1][2] They were used by the Scots and the Irish as work boots to wear in the wet, boggy Scottish and Irish countryside.[3] The word brogue is still used in Britain for a style of dress sho...
