Methodology and results: The ability of the fungal endophytic crude extract to impede Streptococcus mutans biofilm formation was preliminarily screened with Congo red agar test. It was proven that S. mutans biofilm formation was hindered on the agar supplemented with the fungal endophytic crude extract. The antibiofilm activity of the fungal endophytic crude extract was evaluated using a microtiter plate method on both initially formed and preformed biofilm. Antibiofilm activity was recorded in a concentration-dependent pattern whereby higher concentrations reduced biofilm formation better than the lower concentrations of extract for both initially formed and preformed biofilm. The architecture of biofilm tested with fungal endophytic crude extract was also observed. Visualization under a light microscope and SEM revealed that the adherence of S. mutans biofilm treated with fungal endophytic crude extract was significantly reduced in both initially formed and preformed biofilm. In addition, observation under SEM showed that the matrices surrounding the bacterial cells were disintegrated and bacterial cells in biofilm completely lost their original shape. The overall data demonstrated that the ethyl acetate N. spaherica CL-OP30 crude extract showed good antibiofilm activity. Conclusion, significance and impact of study: The antibiofilm study suggested the potential of N. sphaerica CL-OP30 crude extract against S. mutans biofilm by disrupting the biofilm formation, the disintegration of matrices surrounding the biofilm and responsible for the formation of irregular cell shape. This extract may have a promising potential to be developed as an antibiofilm agent.","PeriodicalId":18178,"journal":{"name":"Malaysian Journal of Microbiology","volume":"116 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88850539","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}

The present study aimed to investigate the prevalence rates of the adverse health events experienced by the recipients of COVID-19 vaccines in Saudi Arabia. Methodology and results: A cross-sectional study was conducted in October 2021 using a google form of an online self-administered questionnaire sent via different social media platforms for recruiting participants from southwestern Saudi Arabia. The questionnaire was prepared by medical and public health professionals and then translated into Arabic, pilot-studied and validated. Among the 453 Saudi adults who participated in the study with at least one dose of the COVID-19 vaccine, about (77.9%) were males aged 25.5 +/- 10.6 years. Most of the participants were college students living in the Makkah region. Nearly 68.3% reported post-vaccination adverse events, such as injection site pain/swelling (91.9%), fatigue (67.9%), bone and muscle pain (65.2%) and flu-like symptoms (58%). The type of vaccine was significantly associated with the development of adverse events p=0.002 (OR of Pfizer-BioNTech versus AstraZeneca: 0.33, 95% CI: 0.18-0.61). Additionally, ageing of more than the 3rd decade, male gender and being married were significantly associated with lower rates of reporting post-vaccination adverse events. Conclusion, significance and impact of study: The development of COVID-19 vaccine-related adverse health events had no significant associations with residence, education, occupation, BMI, chronic diseases or smoking. However, age, gender, marital state and vaccine type may be considered significant predictors for developing post-vaccination adverse reactions.","PeriodicalId":18178,"journal":{"name":"Malaysian Journal of Microbiology","volume":"3 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89229382","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}
