A prospective study was carried out in Lek Yuen Social Hygiene Clinic in Hong Kong during 1996-1997 to study the longest survival time of Neisseria gonorrhoeae outside the human body. Fifteen patients with confirmed gonorrhoea were recruited. The patients' urethral discharges were taken for interval cultural analysis in standardised Thayer Martin medium with and without physiological normal saline. The result showed that Neisseria gonorrhoeae could survive up to 20 hours outside human body. The twenty hours in-vitro survival of Neisseria gonorrhoeae provide important information especially when a genitourinary physician is facing a suspected child abuse case in which the clients claimed that the infection was acquired through fomites.

香港瀝源社會衛生科診所於1996至1997年進行一項前瞻性研究,以確定奈瑟氏淋球菌於人體外的最長存活時間。研究選定十五名經確診的淋病患者。將患者的尿道分泌物以Thayer Martin培養基作間段性培養分析,部份標本加有生理鹽水。研究結果顯示奈瑟氏淋球菌可於人體外存活長達二十小時。此項研究結果提供重要臨床資訊,特別是當泌尿生殖科醫生面對一宗懷疑虐兒個案,而當事人堅稱感染是由污染物引起。
