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 determine the distribution of ABO and Rh blood groups in Kurds and to compare it with those of other populations. SUBJECTS AND METHODS The study included blood grouping of total population of 53,234 whose...

Rawat, A K Mandal Department of Pathology, Vardhaman Mahavir Medical College and Safdarjung Hospital, New Delhi, India Background: ABO blood group shows marked geographical and racial variation. The study of regional ABO phenotype is extremely important for understanding the regional demand of rare blood groups and to tide over the massive demands in case of na...

The clinically important Rh blood group system is complex, consisting of multiple distinct antigens. Despite clinical recognition for over 50 years, the Rh blood group antigens have remained poorly understood on a molecular level until the recent identification and characterization of the "Rh polypeptides," the core structural proteins of the Rh antigens. This group of erythrocyte membrane prot...

ABO; Blood groups; Population genetics; Rh (D) Abstract Background: Frequency distribution of blood groups is important as it is used in modern medicine, genetic research, anthropology, and tracing ancestral relations of humans. The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. Aim of the study: To study and do...

Objectives The primary objective of this study was to determine the prevalence of Anaplasma phagocytophilum infection and exposure in adult feral cats in Massachusetts, an endemic area for A phagocytophilum and its tick vector Ixodes scapularis. The secondary objective was to determine if there were correlations between A phagocytophilum infection and the presence of anemia and thrombocytopenia...

BACKGROUND This study was done to know the distribution and frequencies of blood groups among blood donors attending voluntary blood donation camps organized by the Rajendra Institute of Medical Sciences (RIMS), Ranchi, Jharkhand so that demand and supply ratio of the four blood groups can be maintained so that no patient dies due to lack of a particular blood group. CONTEXT Up till now about...

OBJECTIVE To determine the distribution of ABO blood group and rhesus (RH) factor among pregnant women, to estimate the prevalence of Rh alloimmunization, and report the perinatal outcome of all cases of Rh alloimmunization at King Abdul-Aziz University Hospital (KAUH). METHODS This is a retrospective study of pregnant women attending the antenatal clinics in KAUH, Jeddah, Saudi Arabia betwe...
