1. 此類性行為常見的直腸炎致病源並非沙門氏菌、志賀菌、或彎曲桿菌。一件2009年的統計常見MSM(Men who have sex with men) 直腸炎病原體包括淋病(54%)、單純皰疹病毒(29%)、披衣菌(19%)。就算是統計後天免疫缺乏症候群(AIDS)的患者得到腸炎時常見之致病源,沙門氏菌也排不到前頭,前6位分別是巨細胞病毒,隱球菌,微胞球體,阿米巴,梨形鞭毛蟲,念珠菌。
2. 沙門氏菌的的致病機轉常見是汙染的食物,尤其是雞蛋,其主要孳生處主要是小腸的淋巴(Peyer's Patch)構造之M細胞(microfold cells, M cells),亦並非此網站宣稱在直腸接觸即可感染。
3. 由上推測,此網站應是幻想MSM性行為會造成腸炎,然後直接套上常見腸炎的相關資料,包括致病菌,症狀,唯獨傳染途徑錯誤。對於腸道細菌侵犯性腸炎來說,志賀菌、沙門氏菌、彎曲桿菌則確實是常見致病原。
4.對於所有MSM,除非互為穩定單一的伴侶,否則建議每年進行相關傳染病篩檢。
