Erythrocytes from a patient with blood type of A1 became nongenetically reactive with A (anti-B) serum, following the development of gastric cancer. Transient polyagglutinability was also apparent. Thein vitro acetylation of the erythrocyte antigens abolished both the acquired B antigen and the polyagglutination. Although incubation of the heterologous type A1 erythrocytes with the patient's serum did not produce B antigen, deacetylase activity in the serum seems to relate to the acquired B… 
Identification of 5 novel feline erythrocyte antigens based on the presence of naturally occurring alloantibodies.
TLDR
This study represents a first step of FEA identification outside the AB system, and because of its prevalence and association with NOAb, FEA 1 might correspond to the Mik antigen.
ABO blood group and Rh factor distribution in population of Bhopal, Madhya Pradesh
TLDR
This study will be carried out with an objective to provide data regarding gene frequency and distribution of ABO and RH blood groups in the population of Bhopal, Madhya Pradesh, India.
Association of ABO and Rh blood groups to HBV, HCV infections among blood donors in a blood bank of tertiary care teaching hospital in Southern India: A retrospective study
TLDR
In this study conducted to determine the predominant blood group antigen and its association with HBV and HCV seroreactivity, there was no association between blood group antigens with these infections.
ABO, RHESUS BLOOD GROUP AND ALLELE FREQUENCY IN AND AROUND RAIPUR (CHATTISGARH STATE), INDIA -
TLDR
Blood group B was the commonest, closely followed by group O, and O allele to be most common among people in and around Raipur, where more than 95% population is Rh positive.
ABO and rhesus blood group distribution in Kurds
Background: It is well established that ABO and rhesus (Rh) genes and phenotypes vary widely between ethnic groups and both within and between geographical areas. The aim of this study was to
Incidence of ABO and Rh Incompatibility in the Punjabi Couples
Background: ABO & Rh are the major blood group systems from transfusion point of view and reflect the genetic distribution and characteristics of molecular database of different ethnic groups, races,
Dangerous Blood Group ‘O’ Donors Incidents at the Federal Teaching Hospital Abakaliki
TLDR
It was discovered that 36 male donors out of 100 donors studied were positive to haemolysin, which suggests a relatively high level of blood transfusion reactions in this part of the world.
Effect and Association of ABO & Rh Incompatibility on Maternal Outcome
Background: Incompatibility affects those pregnancies in which maternal antibodies when cross the placental barrier and enters the fetal circulation, reacts and damage the fetal red cells, thus
The Frequency of ABO Blood Group among Male Inmates in a Typical Nigerian Prison
TLDR
It is indicated that Blood group O+ had the highest frequency for inmates convicted for the various crimes, and blood type AB+ and AB- had the least frequency.

Atypical Polyagglutination Associated with an Acquired B Antigen
The finding of an acquired B antigen, together with polyagglutination, in an elderly man led to studies indicating adsorption of bacterial material as the likely cause of both of these red blood cell
Immunological Aspects of the Acquired B Antigen
TLDR
By agglutination kinetics using an immune anti‐B, the acquired B reactive structure was found to differ from that of a normal B, points out to the part played by one electrically charged chemical group.
More About an Acquired Group B Antigen
TLDR
The discovery of an acquired B antigen in an A2 individual enabled the existence of a colonic carcinoma before the patient went to surgery, suggesting a relationship with malignancy and/or bacteria, and with further refinements might even serve as a screening test for early detection of some forms of cancer.
Acquired B Antigen Disappearance by in vitvo Acetylation Associated with A1 Activity Restoration
Abstract. The chemical acetylation of RBC bearing the acquired B antigen led to the disappearance of the agglutinability by anti‐B and restored the A1 specificity. The same results are obtained using
Acquisition of a B-Like Antigen by Red Blood Cells
TLDR
The biochemical influences at work in wound healing are quoted to indicate the complicated nature of such problems, and it is suggested that if research is to be undertaken along these lines in a clinical unit it is no good entrusting it to a clinician who dabbles in biochemistry.
