Declining Vibrio parahaemolyticus and Salmonella, increasing Campylobacter and persisting no-rovirus food poisonings: inference derived from Food Poisoning Statistics of Japan.

Declining Vibrio parahaemolyticus and Salmonella, increasing Campylobacter and persisting no-rovirus food poisonings: inference derived from Food Poisoning Statistics of Japan. Jpn J Infect Dis. 2019 Oct 31;: Authors: Yoshikura H Abstract In Japan, from 2000 to 2018, for Vibrio parahaemolyticus and Salmonella food poisonings, the annual number of the outbreaks and that of the patients decreased exponentially though the size of the individual outbreaks (the number of patients per outbreak) tended to become larger. For food poisonings caused by Campylobacter, the annual number of the outbreaks increased exponentially while the outbreak size became smaller and the annual number of the patients remained almost unchanged. For food poisoning caused by norovirus, both the number of the outbreaks and that of the patients remained high throughout. Over time, the geographical and the seasonal distribution of food poisonings became narrower for Vibrio parahaemolyticus and Salmonella, while they became wider for Campylobacter and norovirus. Further analysis using the attack rate-patient number plots suggested that the number of the outbreaks was determined mainly by the levels of the microbial contamination of foods before they were brought into the facilities for consumption.

Krupp, Selma ŠabanovićAbstractAs robots become prevalent, people are increasingly interacting with multiple robots at once. Thus, it is important to not only examine how robot behavior toward humans affects interaction, but how robot behavior toward other robots affects interaction. We examine this in two studies. In Study 1, 630 participants from the USA and Japan viewed a video of one or more minimally social robots interactin...

One of the predisposing factors at molecular level for this cancer is via WNT signaling which is associated with the vast numbers of different genes. Thus, in this study, we aimed to investigate whether Adenomatous Polyposis ...

We reported a general increase of unnecessary urine cultures in both community and hospital patients. The most representative microorganism isolated from Community (58.2%) and Hospital (47.6%) was E. coli. UTIs causative bacteria in hospitalized patients was more than twice as resistant to Trimetoprim/sulphamethoxazole (OR 2.26) and Imipenem (OR 2.56), for Gram-positive and Gram-negative, respectively, than in Community patients. Nitrofurantoin was the only agent without differences in resistance rate between community and hospital UTIs. Therefore, physicians could use it as a definitive therapy for uncomplicated cystitis ...

Authors: Rovida F, Nepita EV, Giardina F, Piralla A, Campanini G, Baldanti F Abstract About 15,000 hospitalizations due to group A Rotavirus gastroenteritis (RVA) are recorded each year in Italy. In the present study, we report the seasonal distribution and molecular characterization of RVA in pediatric and adult hospitalized patients in the period September 2015-April 2018 in Pavia province, Lombardy Region. During the study period, stool samples of 1450 patients with acute gastroenteritis were analyzed and 122 were RVA positive, the majority belonging to pediatric patients (94.0%) while only a minority of patient...

Diego ZuluagaYesterday, Joe Nocera penned an extraordinarycolumn expressing his bafflement at the Trump administration ’sdrive to release Fannie Mae and Freddie Mac, two firms that purchase and guarantee around half of single-family mortgages in the United States, from government conservatorship. Nocera argues against such a move, writing that “if it ain’t broke, don’t fix it . . . Fannie Mae and Freddie Mac ain’t broke.”The piece is disconcerting from start to finish. Nocera writes that Fannie and Freddie make the 30-year fixed-rate mortgage, a product common only in the U.S., possible ...

Conclusions: This study showed that five major sequence variants and CNVs in the EYS gene account for one-third of Japanese patients with arRP and sRP, and these variants are also responsible for RP showing an autosomal dominant inheritance pattern. This is the first report showing the pathogenicity of three missense variants (p.(Gly843Glu), p.(Gly2186Glu), and p.(Ile2188Thr)) and the presence of CNVs in the EYS gene of Japanese patients with arRP and sRP.

Canadian Journal of Microbiology, e-First Articles. Zika virus (ZIKV) is a mosquito-borne virus that was first isolated from Zika forest, Uganda, in 1947. Since its inception, major and minor outbreaks have been documented from several parts of world. Aedes spp. mosquitoes are the primary vectors of ZIKV, but the virus can also be transmitted through sexual practices, materno-fetal transmission, and blood transfusion. The clinical presentations of symptomatic ZIKV infections are similar to dengue and chikungunya, including fever, headache, arthralgia, retro-orbital pain, conjunctivitis, and rash. ZIKV often causes mild ill...

We previously isolated E. coli strains from Japanese colorectal cancer patients, and in the present study we investigated the genotoxic potency of the colibactin-producing (clb+) E. coli strains that carry the polyketide synthases "pks" gene cluste...
