Trueperella pyogenes
open-in-new
<p><i>Trueperella pyogenes</i> is a <a href="/facts/Species/oDg6b96r">species</a> of <a href="/facts/Motility/Df5BECHL">nonmotile</a>, <a href="/facts/Facultative_anaerobic_organism/YS9tdh8N">facultatively anaerobic</a>, <a href="/facts/Gram-positive_bacteria/H6WYQ17e">Gram-positive</a> <a href="/facts/Bacteria/wC8xSCsU">bacteria</a>. The cells typically measure 0.5 by 2.0 <a href="/facts/Micrometre/7eDFxD2L">μm</a>. They appear as <a href="/facts/Pleomorphism_(microbiology)/VbnugWWV">pleomorphic</a> or <a href="/facts/Coccus/51QVlEDC">coccoid</a> rods. They tend to be grouped singly or in short chains but are sometimes grouped into V-shaped pairs. </p><p><i>T. pyogenes</i> is found in the <a href="/facts/Genitourinary_system/u262MFXg">urogenital</a>, <a href="/facts/Gastrointestinal_tract/nK2zwqBS">gastrointestinal</a>, and upper <a href="/facts/Respiratory_tract/nnG9UEmr">respiratory tracts</a> of <a href="/facts/Cattle/44qV9B6S">cattle</a>, <a href="/facts/Goat/BrsPJmdX">goats</a>, <a href="/facts/Horse/uQ3FA0Ak">horses</a>, <a href="/facts/Musk_deer/Rn0boSaM">musk deer</a>, <a href="/facts/Pig/b5wxwdDY">pigs</a>, and <a href="/facts/Sheep/cjkJyI4f">sheep</a>, in which it may cause <a href="/facts/Abscess/BW3TH8kb">abscesses</a>, <a href="/facts/Mastitis/yvcmf1yH">mastitis</a>, <a href="/facts/Metritis/YwglPh8z">metritis</a>, and <a href="/facts/Pneumonia/Jw0KquTA">pneumonia</a>. Although it can thrive in either anaerobic or aerobic environments, it is ideally suited to one with high (about 7%) levels of <a href="/facts/Carbon_dioxide/xGzpppEp">carbon dioxide</a>. </p><p>When the genus <i><a href="/facts/Arcanobacterium/X1z7XFRI">Arcanobacterium</a></i> was split into two (<i>Arcanobacterium</i> and <i>Trueperella</i> gen. nov.), the new genus name was chosen in honor of German <a href="/facts/Microbiologist/cqEyJwNK">microbiologist</a> Hans G. Trüper [de]. The specific name <i>pyogenes</i>, used in various bacterial genera, was derived from the <a href="/facts/Ancient_Greek/LIK7NlUh">Greek</a> <i>puon</i> or <a href="/facts/Latin/pM3Kge85">Latin</a> <i>pyum</i> and suffix <i>-genes</i>, yielding <i>pyogenes</i>, meaning "<a href="/facts/Pus/jzNHzM70">pus</a>-producing". </p><p>Although it can infect a wide variety of tissues, <i>Trueperella pyogenes</i> is the most common cause of "summer mastitis" in cattle and <a href="/facts/Pyometra/RAdFcJty">pyometra</a> in dogs . </p>
