【求助】请教修改翻译

Chemotherapy-induced mucositis is a detrimental side effect of cancer treatment, which may be exacerbated by coexisting changes in the intestinal microflora. Intestinal microflora has been shown to translocate after cancer treatment, causing localised infection and/or bacteraemia. Host-beneficial microflora function may also be compromised during treatment with chemotherapy, contributing to the severe, dose-limiting side effects of cancer chemotherapy.

这是本人的翻译 ：化疗引起的黏膜炎是癌症治疗产生一种有害的副作用，可因肠道菌群共存的变化而加重。化疗造成肠道菌群出现易位，可导致肠道局部感染或者菌血症，宿主有益菌群的功能也可在化疗过程中受到牵连，导致严重的、剂量限制性的化疗副作用的发生。请坛友们帮忙修改，其中coexisting changes in the intestinal microflora应该怎么翻译更好？
