Carriage of Neisseria species in communities with different rates of meningococcal disease

A single clone, Neisseria meningitidis serogroup C (C:2a:P1.2), was isolated from seven patients during a cluster of cases of meningococcal disease in Ontario in 1989. To determine whether the clone was present in asymptomatic individuals in the same population, pharyngeal swabs were taken from 7% (644 of 9125) of residents who were vaccinated during the outbreak. Rates of isolation of Neisseria species were also compared to those in two other geographical areas which did not have an elevated incidence of meningococcal disease. The rate of carriage of N meningitidis in the asymptomatic individuals sampled was between 1.9% and 5.4%. The clone isolated from patients was not present among the carrier strains as determined by sero- and subtyping and electrophoretic analysis of metabolic enzymes. Age greater than six years was the only factor associated with colonization with N meningitidis

Corporate Tax Incidence in India

The paper attempts to measure the incidence of corporate income tax in India under a general equilibrium setting. Using seemingly uncorrelated regression coefficients and dynamic panel estimates, we tried to analyze both the relative burden of corporate tax borne by capital and labor and the efficiency effects of corporate income tax. The data for the study is compiled from corporate firms listed on the Bombay Stock Exchange (BSE) and the National Stock Exchange of India (NSE) for the period 2000-15. Our empirical estimates suggest that in India capital bears more of the burden of corporate taxes than labor. Though it is contrary to the Harberger (1962) hypothesis that the burden of corporate tax is shifted to labor rather than capital, it confirms the existing empirical results in the context of India
