Impaired T-cell responses to mitogens and high T-cell activation marker (TAM) expression on Mycobacterium tuberculosis –specific T-cells characterize immunopathology in patients with tuberculosis (TB). In a study of patients with TB ( n = 60) and asymptomatic contacts (controls, n = 37), we found that TB patients had higher CD38 + T-cell proportions specific for M. tuberculosis protein (PPD Mtb ), yet total proportions of PPD...

Yet, the application of the trophic level concept to aquaculture is complex, and its value for assessing sustainability is further complicated by continual reformulation of feeds. The majority of fed farmed fish and invertebrate species are produced using human‐made compound feeds that can differ markedly from the diet of...
