HIMEDIA HiCrome 顯色培養基(/產色培養基/呈色培養基) |
顯色培養基(/產色培養基/呈色培養基)
                                
( Chromogenic / Fluorogenic Culture Media )
顯色培養基一般是在培養基中加入檢測特定菌種的特殊性底物。
        (一種或多種顯色劑(目測) 或 熒光顯色劑(紫外燈照射觀察) )
該特殊性底物 與 特定微生物自身代謝產生的酶 會產生顯色(產色)情形,
藉此直接觀察菌落顏色即可對菌種做出鑑定,
其反應的靈敏度和特異性大大優於傳統培養基。
顯色培養基通常為乾粉狀,容易儲存。
加蒸餾水溶解後,部分產品無須高壓滅菌,培養時間依具體培養基而定,
通常是18-24小時,比傳統時間顯著縮短。
HiMedia – M1938 HiCrome™ Acinetobacter Agar Base |
Recommended for selective isolation of Acinetobacter species from environmental and clinical samples.

Principle and Interpretation
Acinetobacter species are gram negative ubiquitous bacteria that have been isolated from patients with nosocomial infection, environment, soil, and water. Acinetobacter is mostly found in every type of infections (3). There is an alarming situation as Acinetobacter baumannii is found to be resistant to most commonly used antibiotics which includes betalactams and aminoglycosides (2,3). Immunocompromised patients requiring mechanical respirations are at more risk of infection by Acinetobacter species.(1) Peptone special provides nitrogeneous and carbonaceous compounds, long chain amino acids and vitamins to the organisms. Sodium chloride maintains the osmotic balance. Selective mix inhibits gram positive organisms. The chromogenic mixture in the medium allows the differentiation of Acinetobacter species from other organisms.

原理與解釋
不動桿菌屬是革蘭氏陰性普遍存在的細菌,已從醫院感染,環境,土壤和水中分離出來。 不動桿菌主要存在於各種類型的感染中(3)。 令人擔憂的是,鮑曼不動桿菌被發現對大多數常用的抗生素有抗藥性,其中包括β-內酰胺和氨基糖苷類(2,3)。 需要機械呼吸的免疫功能低下的患者更容易被不動桿菌屬感染。(1) 蛋白腖特別為生物體提供硝基和含碳化合物,長鏈氨基酸和維生素。 氯化鈉保持滲透平衡。 選擇性混合抑制革蘭氏陽性生物。 培養基中的顯色混合物允許不動桿菌屬物種與其他生物體的分化。
