This study reports the evolution and dynamics of 527 HA protein sequences of influenza A/(H1N1)pdm09 Indian isolates submitted from 2009 to 2020. These isolates were aligned with a reference sequence and 22 sequences representing different clades using MEGA X, and subjected to phylogenetic analysis. The strains were predominantly grouped in clades 6B.1 and 6B.2. Prediction of glycosylation sites using the BioEdit and NetNglyc servers showed 12 glycosylation sites distributed in both the stem and globular head regions of HA. Functional evaluation showed that there were 22 deleterious mutations that could affect the function of HA. In addition, 403 unique mutations were distributed across various isolates, indicating the dynamics of antigenic variation in Indian isolates. These results provide an understanding of the frequency, phylodynamics, and impact of mutations in Indian isolates of influenza A/(H1N1)pdm09 relative to global isolates. Monitoring the genomic evolution of the virus will support studies on strain selection for vaccine development and devising control and prevention measures to manage this respiratory infection.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"76 4","pages":"219-225"},"PeriodicalIF":2.2,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9860331","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}

We then compared these Japanese SaV sequences with 3,119 publicly available human SaV sequences collected from 49 countries over the last 46 years. The results indicated that GI.1, and GI.2 have been the predominant genotypes in Japan, as well as in other countries, over at least four decades.

Here, 6-8w wild-type or Pellino E3 Ubiquitin Protein Ligase Family Member 3 (Peli3)-deficient mice were injected with Staphylococcus aureus to induce osteomyelitis. RAW264.7 cells or bone marrow-derived macrophages isolated from mice were treated with lipopolysaccharide (LPS). Knocking down Peli3 in RAW264.7 cells increased the expression of inflammatory cytokines (interleukin-1β, interleukin-6, and tumor necrosis factor-α) after LPS stimulation. Inflammation was also activated in S. aureus-induced Peli3-deficient mice. Moreover, S. aureus-infected Peli3-deficient mice also displayed more severe symptoms of osteomyelitis than S. aureus-infected wild-type mice. Moreover, Peli3 targets and degrades RIPK2 through K48-linked ubiquitination, and negatively modulates osteomyelitis by degrading RIPK2. Our data further expands the current understanding of RIPK2 in osteomyelitis, and suggests that RIPK2 might serve as a novel therapeutic target for treating osteomyelitis.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"76 4","pages":"240-245"},"PeriodicalIF":2.2,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9860052","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}

A total of 142 patients with RSV infection (aged between 2 months and 5 years) who presented with ALRTI between December 2013 and March 2016 were enrolled. Their nasopharyngeal aspirates were subjected to RSV viral load quantification, and local cytokine levels of interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), IL-17A, interferon γ (IFN-γ), and IL-10 were determined using a cytokine bead array. The levels of MMP-9 and TIMP-1 in 109 aspirates were calculated using Quantikine ELISA. These parameters were compared for different disease severity categories. A higher viral load and increased levels of TNF-α, MMP-9, and MMP-9:TIMP-1 were associated with greater severity of disease; whereas levels of IL-17A, IFN-γ, and IFN-γ:IL-10 were associated with disease resolution. When defining the transition from non-severe to severe disease, MMP-9 had a sensitivity and specificity of 89.7% and 85.4%, respectively. Moreover, MMP-9:TIMP-1 had a sensitivity and specificity of 87.2% and 76.8%, respectively. Hence, MMP-9, MMP-9:TIMP-1, TNF-α, and IL-10 could serve as potential biomarkers for disease progression in RSV-infected children.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"76 4","pages":"233-239"},"PeriodicalIF":2.2,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9970982","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}

N. gonorrhoeae multi-antigen sequence typing (NG-MAST) was conducted for genotyping, and phylogenetic analysis was performed using the porB and tbpB sequences. The results showed that antimicrobial resistance against ciprofloxacin, tetracycline, and penicillin was high, and these drugs are no longer recommended for the treatment of gonorrhea. All isolates were susceptible to spectinomycin. However, in 2016-2021, a total of 15 (5.5%) ceftriaxone (CRO)-resistant strains and 31 (11.4%) isolates with decreased susceptibility to CRO were found, and the resistance rate to azithromycin had reached 7.1% in 2016-2017. Epidemiologically, the mosaic penA allele was identified in all CRO-resistant isolates. Based on NG-MAST, ST5061 was the most prevalent ST. Phylogenetic analysis suggested that the resistant isolates did not cluster independently. Despite focus on the local situation, this study raises the need for better gonorrhea medication and highlights that CRO may not be adequate as first-line treatment for gonorrhea in Changsha.","PeriodicalId":14608,"journal":{"name":"Japanese journal of infectious diseases","volume":"76 3","pages":"167-173"},"PeriodicalIF":2.2,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9524067","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}
