Because the clinical signs of human brucellosis are so varied and vague, scientific confirmation via organism isolation or antibody detection is required to confirm the diagnosis. The aim of this work is measurement of the sensitivity and specificity of PCR for the detection of Brucella abortus BCSP31gene compared with the blood culture methods.Methods: A total of 97 patients from different ages with symptoms of brucellosis were included in the study. This research study was carried out at Mansoura University Hospitals. The sensitivity and specificity of polymerase chain reaction (PCR) for the detection of BCSP31gene of Brucella abortus compared with blood culture methods.Results: In positive PCR cases of brucella (total 14), a single band of a 223-bp corresponding to BCSP31gene was obtained. The true positive brucellosis cases (n = 6) are positive of blood culture and PCR. PCR was sensitive than blood culture for diagnosis of brucellosis since the sensitivity and specificity of PCR are 87.5% and 98.73% and the sensitivity and specificity of blood culture are 84.62% and 96.15%. The positive and negative predictive values of PCR are 86.56% and 94.80% and the positive and negative predictive values of blood culture are 78.98% and 92.54%. The accuracy (%) of PCR and blood culture is 94.72% and 90.67%. The PCR assay was shown to be more sensitive and specific. Conclusion: The PCR showed higher efficiency for rapid diagnosis of human brucellosis, as compared to the blood culture method.","PeriodicalId":210712,"journal":{"name":"Alfarama Journal of Basic & Applied Sciences","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114940901","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}

Plankton nets of 20 µm mesh size were used in collecting samples, then samples fixed on board in 4% buffered formalin. A total of 149 species of tintinnids belonging to 12 families and 36 genera of the order Choreotrichida were identified based on the morphological features. Families Codonellidae, Tintinnidae, and Codonellopsidae had the higher number of species (40, 28 and 20 species, respectively), constituting collectively around 60% of the total number of recorded species. The highest number of genera was represented in Family Tintinnidae (8), while the highest number of species was representedin Genus Tintinnopsis (34).Further studies are needed to explore the species composition of this important group of zooplankton that helps to understand dynamics of zooplankton community and the food chain in the marine environment.","PeriodicalId":210712,"journal":{"name":"Alfarama Journal of Basic & Applied Sciences","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121370122","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 prevalence ratio of bacterial infection of all infected larvae was 101 larvae (55.5%). The highest number of infected larvae was recorded in summer (45 larvae, 86.5%), while the lowest was recorded in winter (10 larvae, 25%). The most frequently encountered Vibrio sp. was V. harveyi which was isolated from 28 fish larvae followed by V. parahaemolyticus which was isolated from 25 fish larvae.

For synthesis of WTS/DaMK based geopolymer, five mixes of WTS/DaMK (75/25, 80/20, 85/15, 90/10 and 95/5, respectively) are tested to obtain the optimum synthesis condition based on the compressive strength. Results showed that the geopolymer mortar with 85/15WTS/DaMK has the highest compressive strength (8 MPa). In addition, X-ray Diffraction (XRD) and X-ray Fluorescence (XRF) techniques are used to characterize the mineral and chemical compositions of WTS and DaMK. WTS/DaMK based geopolymer mortar have been tested for leaching to study its immobilization behavior under the optimum condition. The Cd2+, Pb2+ and Hg2+ ions were used and effectively immobilized in this study. The heavy metals with concentrations of 100, 200 and 300 ppm were used in the geopolymer matrix giving about 98% of immobilization efficiency. The study showed that Pb2+ has the best immobilization efficiency followed by Hg2+ and Cd2+ with high concentrations.","PeriodicalId":210712,"journal":{"name":"Alfarama Journal of Basic & Applied Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129309855","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}
