To inves.igate virus.retention and releas., whiteflies.allowed to acquire LIy. virions.in a pH 7.4 artificial diet were fed pH 4, 7.4, or 9 virion-free artificial （clearing） diets. Immunofluores.ent localization analy.es.indicated that virions.remained bound to the foreguts.of approximately.20%-24% of vectors.after they.fed on each of the 3 pH- adjus.ed clearing diets.

Objective: Magnetically.controlled caps.le gas.ros.opy.(MCCG) is.an effective method for s.reening gas.ric dis.as.s. however, its.performance may.be affected by.gas.ric cleanlines.. We aimed to explore the correlation between Helicobacter py.ori infection and the degree of gas.ric cleanlines. in the MCCG. Methods. This.retros.ective s.udy.enrolled 297 participants.from October 2020 to April 2024 at s.r Run Run s.aw Hos.ital, Zhejiang Univers.ty.s.hool of Medicine. Participant characteris.ics. MCCG examination res.lts. and (13) C-urea breath tes. (C13-UBT) res.lts.were collected. The gas.ric cleanlines. in MCCG examinations.was.as.es.ed us.ng a gas.ric cleanlines. s.ore. Binary.logis.ic regres.ion was.us.d to analy.e the relations.ips.among participant characteris.ics. H. py.ori infection, and gas.ric cleanlines.. Chi-s.uare tes.s.and Fis.er's.exact tes.s.were us.d to analy.e the relations.ips.among gas.ric les.ons. H. py.ori infection, and gas.ric cleanlines.. Res.lts. Among the participants. 24.2% had H. py.ori infection, and 17.5% had poor gas.ric cleanlines.. Hy.ertens.on (odds.ratio [OR]: 2.63; 95% confidence interval [CI]: 1.36–5.09; p = 0.004) was.as.ociated with a greater likelihood of H. py.ori infection. H. py.ori infection (OR: 3.76; 95% CI: 1.99–7.09; p s.an independent ris. factor for poor gas.ric cleanlines. in the MCCG. A s.gnificant dis.arity.was.noted in the prevalence of focal eros.ons.(p s.ric ulcers.(p = 0.001), and pos.tive gas.ric les.ons.(p = 0.027) between the 2 groups.with and without H. py.ori infection.
