01 / REMEMBER THE NAME

Remember the name

/bəˈsɪləri ˈdɪsənteri/

bacill- 杆菌；dys- 异常；enter- 肠；-y 状态

Chinese sound mnemonic

“迪森特瑞”想“蹲十次仍想蹲”：少量血便、里急后重。（原发音近似：伯-西-勒-瑞／迪-森-特-瑞）

Mnemonics support recall; use the IPA for pronunciation.

02 / CONNECT THE MECHANISM

Colonic mucosal invasion → inflammation and ulceration → tenesmus and bloody stool.

A traveller has fever, abdominal cramps, tenesmus and frequent small-volume bloody stools.

tenesmus 里急后重；bloody diarrhea 血性腹泻；fecal-oral transmission 粪口传播

03 / CHECK & DISTINGUISH

Important investigations

粪便PCR或培养；评价脱水

Distinguishing features

霍乱为大量无痛水样便，痢疾偏小量血便伴疼痛；溃疡性结肠炎为反复慢性病程，需粪便病原检测排感染。

Red flags & referral

明显脱水、持续血便、意识改变、败血症征象→当日急评；注意粪口传播及公共卫生报告。
