It has three classic clinical variants: fixed, lymphangitic, and systemic. Treatment in most cases has been itraconazole or potassium iodide. The aim of this paper is to communicate an unusual relapsing case treated with IK. We report a 73-year-old woman with lymphangitic sporotrichosis, adequate response to treatment with potassium iodide, and recurrence 15 months after. A molecular test was performed through the amplification of a 331 bp fragment of the calmodulin gene. In both infections, the same specie was isolated. The effects of potassium iodide are briefly discussed, and we conclude that the same treatment can be prescribed, if no side effects are observed.","PeriodicalId":56408,"journal":{"name":"微生物学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70486971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It affects humans of all ages and races causing most cases of viral gastroenteritis worldwide. Infection results from ingestion of contaminated food or water as well as causing diarrhea and vomiting in humans. Extracts from plants are known to have antioxidant, anti-inflammatory, and adhesive properties which are associated with barrier functions. The aim of this study was to elucidate whether plaque reduction was due to an effect of methanolic plant extract directly on the virus, whether the extract affects viral replication, and lastly, whether the extract disrupts the cell surface binding with the virus. The plant extracts of interest were the calyces of Hibiscus sabdariffa (HS) and the seeds of Zanthoxylum armatum (ZA). Antiviral activities of these extracts were determined against murine norovirus. The logarithmic viral reduction per pla-que-forming unit was (22 log 10 ) PFU/ml (control), (15 log 10 ) PFU/ml (treated HS), and (12 log 10 ) PFU/ml (treated ZA) with a significant reduction (68% and","PeriodicalId":56408,"journal":{"name":"微生物学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70487081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims to establish a biomoniting system based on fission yeast to assess the genotoxity and mutangenecity of environmental cadmium ions. Methods: Rad22-GFP DNA repair foci examination, articifical mini-chromosome loss test, and real-time quantitative PCR. Results: Using PCR-based techniques and homologous recombination, a yeast strain called Rad22-GFP was constructed as an indicator of environmental genotoxic agents, in which the DNA damge associated gene Rad22 was tagged with GFP in its chromosomal locus. Under Cd exposure, this indicator strain displayed multiple (>2) DNA repair foci, whereas none was observed with untreated control. As for the positive control strain SPBC776.03 Δ, multiple (>2) DNA repair foci were observed during cell cycle even in the absence of Cd stress. Real-time qPCR analyses have revealed that, SPBC776.03 transcriptional levels were found to downregulate by three-fold when exposed to Cd 2+ , in contrast to untreated wild-type counterparts, suggesting that SPBC776.03 would be a responsive gene of fission yeast to the Cd stress. Conclusions: Our studies have constructed a biomointoring system of envirommental cadmium exposure based on fluorescence-tagged Rad22 expression, Rad22-GFP, in fission yeast, which has advantages of speediness and convenience in the assessment of Cd toxicity.","PeriodicalId":56408,"journal":{"name":"微生物学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66128403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
