Chromobacterium violaceum, a soil and water inhabitant, has been implicated in human disease with a high mortality rate, particularly in the southeastern United States. The psychrotrophic Chromobacterium lividum has been isolated from foods, water, and soil, but is not considered pathogenic. To determine the distribution of Chromobacterium spp. in soil, water, and foods in the Gainesville area, we evaluated Bennett, Ryalls and Moss, and Aeromonas membrane agars for their ability to recover these organisms from various samples when incubated at 25 or 35 degrees C. Bennett agar was best for the isolation of both species when incubated at 25 degrees C; however, at 35 degrees C, Aeromonas membrane agar gave the highest recoveries of C. violaceum. C. violaceum was recovered only from soil and water, whereas C. lividum was frequently recovered from foods as well as soil and water.
紫色色杆菌是一种存在于土壤和水中的细菌，它与人类疾病有关，死亡率很高，在美国东南部尤为如此。嗜冷的青灰色色杆菌已从食物、水和土壤中分离出来，但不被认为具有致病性。为了确定盖恩斯维尔地区土壤、水和食物中色杆菌属的分布情况，我们评估了贝内特琼脂、赖尔斯和莫斯琼脂以及气单胞菌膜琼脂在25或35摄氏度下孵育时从各种样本中分离出这些细菌的能力。在25摄氏度下孵育时，贝内特琼脂最适合分离这两种细菌；然而，在35摄氏度下，气单胞菌膜琼脂对紫色色杆菌的回收率最高。紫色色杆菌仅从土壤和水中分离出来，而青灰色色杆菌经常从食物以及土壤和水中分离出来。
