This study examined the antimicrobial susceptibility and genetic relationship based on Clermont phylotyping and enterobacterial repetitive intergenic consensus (ERIC)-PCR of 84 E. coli urinary isolates from provincial and community hospitals in Thailand. All isolates were susceptible to nitrofurantoin, and almost all isolates were susceptible to carbapenem, fosfomycin, and amikacin. High resistance rates to fluoroquinolone, ampicillin, and trimethoprim/sulfamethoxazole were observed. Clermont phylogroup B2 was predominant (n = 58). Subtyping of the B2 phylogroup revealed diverse subgroups, of which subgroup V (n = 11), VII (n = 9), III (n = 6), and II (n = 6) were most prevalent. ERIC-PCR showed that the strains of the B2 subgroups III and V were spread between provincial and community hospitals and between hospital wards. This evidence suggests the need for comprehensive infection control monitoring, with strong active surveillance at all hospital levels.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":" ","pages":"220-226"},"PeriodicalIF":1.3,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139990067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biofilm inhibition and eradication by nanoparticles with and without the addition of oxacillin was assessed on staphylococcal strains. Cur-Chi-MNP showed antimicrobial activity on planktonic cells of MRSA and MR-CoNS strains and inhibited biofilm of MRSA. The addition of OXA to Cur-Chi-MNP increased biofilm inhibition and eradication activity against all Staphylococci strains (p=0.0007); higher biofilm activity was observed in early biofilm stages. Cur-Chi-MNP showed antimicrobial and biofilm inhibition activity against S. aureus. The addition of OXA increased biofilm inhibition and eradication activity against all Staphylococci strains.

The number of reported PCF cases in Osaka decreased from 2020 to 2022, followed by an unprecedented increase in 2023. HAdV-C strains, including types C1, C2, and C5, were annually detected in pathogen surveillance in Osaka. HAdV-B3 was not detected for 2 years and 9 months from March 2020, and the number of detections increased from July 2023. In total, HAdV-B3 was the most frequently detected (27 of 52 strains), and genetic analysis of its hexon hypervariable regions showed that, except for one strain, the HAdV-B3 strains identified after 2022 had different amino acid substitutions compared to those identified in 2019 and 2020. These results suggest that the PCF epidemic in 2023 was predominantly caused by variant strains of HAdV-B3, and children who have not acquired immunity against HAdV-B3 between 2020 and 2022 were thought to be infected. The impact of COVID-19 on the prevalence of HAdV infections needs to be continuously evaluated through surveillance.\u0000","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"45 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141189533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was a particularly sharp rise in the number of reported cases from 2021 to 2022. Comparing 2020 to 2022, the number of syphilis cases among women in their 20s, rapidly increased, more than triple. Furthermore, the number of pregnant women among syphilis cases increased in 2022. Despite the rapid increase in the number of young women with syphilis, there has been no increase in cases of congenital syphilis. One of the reasons may be that syphilis was detected early in pregnancy due to the high antenatal checkup rate in Tokyo. However, the continued incidence of syphilis among young women may increase congenital syphilis in the future. Public health strategy should include educational activities targeting high-risk populations or adolescents, early and appropriate testing, and treatment for preventing progression of syphilis.\u0000","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"85 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141189534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This creates a conducive environment for-transmission of various zoonotic diseases that affect both humans and animals. Hawaiʻi has experienced an increase in outbreaks of dengue, leptospirosis, and murine typhus. Further, toxoplasmosis and neuroangiostrongyliasis cases remain prevalent throughout the state, and the putative presence of autochthonous Zika cases in a retrospective study may be of national public health concern. Understanding the factors that affect the transmission and distribution of zoonoses is necessary to identify at-risk places and populations. The One Health approach seeks to understand, report, and interpret these factors and requires collaborations between private and government institutions. One Health should focus its efforts on neglected tropical diseases (NTD) and prioritize intervention development to control and prevent the transmission of diseases that spread between animals and humans.
