Viral loads from respiratory samples were measured and considered an indication of active virus replication and used for monitoring severe viral respiratory tract infections routinely. Objective: is to evaluate if the nasopharyngeal viral load has any link with known clinical parameters at disease progression in cases infected with (SARS-CoV-2) during the early three months (May, June, July /2020) of the epidemic in Fayoum University Hospitals. Methodology: Nasopharyngeal swabs were taken from cases with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and viral loads were detected by real-time Reversed transcriptase polymerase chain reaction (RT-PCR) according to cycle threshold (Ct) where high viral load means Ct value <25, moderate viral load; Ct value is from 25 to 35 and low viral load means Ct value >35. Results: Moderate and high NP viral load were significantly higher in patients with fever, upper respiratory tract symptoms, bone aches, and vomiting. High levels of both CRP (p=0.021) and CT findings (p=0.005) were significantly associated with moderate and high viral load. There were significant differences between viral loads groups as regards the occupation of HCWs (p=0.005). Conclusion: SARS-CoV-2 viral load were high in the nasopharynx at the early phase of infection; also high viral load were noticed more in HCWs.","PeriodicalId":22549,"journal":{"name":"The Egyptian Journal of Medical Microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88333471","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}

Objective : The goal of this study is to screen vancomycin resistance among MRSA isolates, determine antimicrobial resistance pattern and evaluate the distribution of virulence genes among these isolates. Methodology : A total of 127 S. aureus clinical isolates were used, MRSA isolates were identified and antimicrobial sensitivity pattern for nine antimicrobial agents from different classes was assessed. In addition, vancomycin MIC was determined by standard agar dilution method and PCR identification of vancomycin resistance encoding genes vanA and vanB was performed. Moreover, the prevalence of eight different virulence genes was determined among different vancomycin resistance categories. Results : All isolates were identified phenotypically as MRSA. However, mecA gene was detected only in 95.28% of isolates. The highest and lowest percentage of resistance was recorded for clindamycin (82.68%) and trimethoprim (11.81%), respectively. Vancomycin resistance level was 23.62% of isolates, while vanA and vanB genes were detected only in 16.67% and 10% of VRSA isolates, respectively. The highest prevalence of virulence genes was found for icaA, followed by hld, hlb, icaD, hlg, hla, tsst and cna, respectively in the tested isolates. In addition, VRSA isolates showed higher mean virulence score (MVS) of 3.6 compared to VISA and VSSA isolates. Conclusion : This study highlights the alarming problem of the increasing incidence of VRSA infections in Egypt. Therefore, there is an urgent need to rationalize vancomycin consumption and to continuously monitor the prevalence of VRSA strains.","PeriodicalId":22549,"journal":{"name":"The Egyptian Journal of Medical Microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78108083","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}

Objective: The aim of this study was to evaluate the prevalence of carbapenemase-producing K. pneumoniae strains among various clinical specimens obtained from different wards and to detect KPC as a mechanism of resistance. Methodology: 100 samples (55urine and 45sputum) were collected from outpatients and inpatients attending urology and chest departments in Beni Suef University Hospital aiming to isolate K. pneumoniae during the period of December 2016 to January 2018. The isolates were tested for susceptibility to ertapenem using E test. Resistant isolates were subjected to phenotypic detection of carbapenemase production by Modified Hodge Test (MHT) and molecular assessment of KPC gene by PCR. Phylogentic tree analysis was used to detect their relationship by DNA sequencing reaction. Results: K.pneumoniae were isolated from 31(31%) of the samples taken. Out of them 19(61.8%) were resistant to ertapenem by E test. By phenotypic method,17/19 (89.4%) were positive for carbapenemase by MHT; and only 13 out of them (76.4%) were confirmed as KPC by PCR. Conclusion: High rate of carbapenem-resistance in K. pneumoniae by both phenotypic and molecular methods was observed. These results warrant more firm infection control measures along with a strictly implemented antibiotic stewardship program to prevent their spread.","PeriodicalId":22549,"journal":{"name":"The Egyptian Journal of Medical Microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73777153","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}

Therefore, the understanding and control of the microbial infections are of great importance for the enhanced healing and management of wounds. Reducing the wound healing time is important as it lowers the risk of infection and decreases possible complications. Grape seed extract is rich in powerful antioxidant compounds. Accordingly, grape seed extract (GSE) alone or in combination with chemical agents might be of beneficial value in wound healing. Objective: The present study aimed to evaluate the topical application of grape seed extract on wound healing of induced Staphylococcus aureus infected skin wound in diabetic rats. Methodology: Ninety male Sprague-Dawley rats weighing 150–200 grams were divided into five groups. All groups were anesthetized, shaved, and exposed to round full-thickness punch biopsy on the back: group I (control); group II (wounded); group III (wounded Staphylococcus aureus infected); group IV (wounded STZ diabetic) and group V (wounded STZ diabetic infected with Staphylococcus aureus). These last four groups were subdivided into Vaseline base treated or GSE- Vaseline treated groups. Macroscopic examination were observed at 0, 1, 3, 6, 8, 12 and 16 days after skin biopsy. Wound contraction data were expressed as a percentage of the initial wound area. Skin homogenates were prepared for determining the immunological parameters TNF-α, IL-10 TGF-β1. Results: Grape seed extract topical application improved the skin homogenate contents of TGF- β1, IL-10 and TNF-α denoting the immunological effect of GSE on wound healing in different experimental groups. Skin histopathological examination was in agreement with the immunological results. Conclusion: Grape seed extract topical application promoted skin wound contraction and closure. Furthermore, it possesses antioxidant and antibacterial properties. Grape seed extract has also strong immunoregulating properties of the skin immune system in Staphylococcus aureus infected diabetic wounded rats.","PeriodicalId":22549,"journal":{"name":"The Egyptian Journal of Medical Microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78472398","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}
