Pregnant women can pass an "active" CMV infection on to their unborn baby. a) AB negative, CMV negative, Hgb S negative; irradiated or O negative, CMV negative, Hgb S negative Either AB-negative or O-negative RBCs may be given to an AB-positive baby because both types are ABO compatible and lack the D antigen 2.8 doses- give 4 doses. In fact, in some countries like the US, A negative, B negative, AB negative, and AB positive are rarer than the O negative. Cytomegalovirus (CMV) is a member of the human herpesvirus family and is widely distributed in the population. However, not all of the ethnic groups share the same proportions of O negative blood types. The "antigens" are special molecules that can elicit an immune response. CMV-neg isn't a blood type, it's just an indicator of exposure to cytomegalovirus. CMV is estimated to cause up to 12% of all sensorineural hearing loss (Peckham et al, 1987) and 10% of cerebral palsy. CMV is in the same family of viruses that causes cold sores (herpes simplex virus), infectious mononucleosis (Epstein-Barr virus), and chickenpox/shingles (varicella zoster virus).

Air ambulances and emergency response vehicles carry O negative supplies for emergencies. The list below shows the percentage of donors with each blood type: O positive: 35%. The percentage of CD27-CD28 - (A), CD85j + (B) and CD244 + (C) CD8 T cells was analysed on PBMC gated on CMV pentamer-positive (left) and pentamer-negative (right) CD8 T cells in young, middle aged and elderly donors.

In CMV-seropositive GPA patients we observed negative correlations between the percentages of CD4+CD28- T cells and both the percentage of naive T cells and the glomerular filtration rate at presentation.
