“…The criteria used for clinical symptom classification is listed in S2 Table. To determine the potential gene loss during laboratory culture, the presence/absence of ctxAB, zot, ace, cep and tcpA were examined by PCR amplification within three days of isolation (most were tested within a day). In a previous study, it has been reported that ctxAB genes of V. cholerae isolates can be lost in culture, however, the earliest loss took place four days after isolation and the loss was not only the ctxAB genes but also the other genes of the CTX prophage [29]. Thus, although the ctxAB genes are on a mobile element, the probability of loss during laboratory culturing should be small for our collection.…”

“…полногеномное секвенирование двух произвольно выбранных му-тантов из 10 полученных, один из которых был про-изводным типичного штамма (м888), а второй -генетически измененного (р18899), показало, что их нетоксигенность обусловлена утратой профага CTXφ, несущего гены ctxAB [3]. для выяснения влияния делеции профага на изменение экспрессии других генов, связанных с биосинтезом дополни-тельных факторов патогенности или выживанием в окружающей среде, проведен сравнительный анализ фенотипов двух пар изогенных штаммов -м888 и м888ΔCTXφ, р18899 и р18899ΔCTXφ.…”

“…поскольку сниженная способность к формиро-ванию биопленки у нетоксигенных штаммов могла быть связана не только с изменением продукции VPS, но и их подвижности [3], мы сравнивали изогенные штаммы по этому свойству. в результате установле-но, что делеция профага CTXφ действительно приво-дит к изменению подвижности.…”
