Seroprevalence of Hepatitis-B surface antigen among the patients reporting at tertiary care Hospital from India

Background: Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a global health problem.Objectives: To estimate the Seroprevalence of HBsAg and its age and sex wise distribution in a hospital based population.Materials and Methods: Serum samples collected over a period of 12 months from patients attending OPDs and admitted to various IPDs of Krishna Hospital and Medical Research Center Karad, were included in the study. Seroprevalence of Hepatitis B surface antigen among hospital based general population was determined using a third generation ELISA.Statistical analysis: Percentages, chi square test.Results: A total number of 7373 patients were screened for HBsAg, among them 3238 (43.92%) were males and 4135 (56.08%) were females. The seroprevalence of HBsAg was 166 (2.25%). The seroprevalence of HBsAg was higher in males 85 (2.63%) as compared to females 81 (1.96%). The highest seroprevalence was found to be among 51-60 years age group (5.24%).Bangladesh Journal of Medical Science Vol.15(3) 2016 p.455-459

Mapping of stripe rust resistance QTL in Cappelle-Desprez × PBW343 RIL population effective in northern wheat belt of India

Stripe rust caused by Puccinia striiformis f. sp. tritici is most important and devastating disease of wheat worldwide, which affects the grain yields, quality and nutrition. To elucidate, the genetic basis of resistance, a mapping population of recombinant inbred lines was developed from a cross between resistant Cappelle-Desprez and susceptible cultivar PBW343 using single-seed descent. Variety PBW343 had been one of the most popular cultivars of North Western Plains Zone, for more than a decade, before succumbing to the stripe rust. Cappelle-Desprez, a source of durable adult plant resistance, has maintained its resistance against stripe rust for a long time in Europe. Map construction and QTL analysis were completed with 1012 polymorphic (DArT and SSR) markers. Screenings for stripe rust disease were carried out in field condition for two consecutive crop seasons (2012-2013 and 2013-2014). Susceptible parent (PBW343) achieved a significant level of disease i.e., 100 % in both the years. In present investigations, resistance in Cappelle-Desprez was found stable and response to the rust ranged from 0 to 1.5 % over the years. The estimated broad-sense heritability (h ²) of stripe rust rAUDPC in the mapping population was 0.82. The relative area under the disease progress curve data showed continuous distributions, indicating that trait was controlled multigenically. Genomic region identified on chromosome 2D, was located within the short arm, with flanking markers (Xgwm484-Xcfd73), explained phenotypic variation (PVE) ranged from 13.9 to 31.8 %. The genomic region identified on chromosome 5B was found with the effect of maximum contribution with flanking DArT markers (1376633|F|0-1207571|F|0), PVE ranged from 24 to 27.0 %. This can, therefore, be utilized for marker assisted selection in developing much needed stripe rust resistant lines for the northern wheat belt of India.
