Classification of blood into groups is based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). Blood groups are genetically determined and exhibit polymorphism in different populations.  ABO blood groups are the most investigated blood group system, and they have been used as genetic markers of populations. , It is well established that ABO blood groups vary widely both within and among ethnic groups and across the geographical boundaries.  The blood group distribution in different groups of population is important in health care and blood transfusion. ,
The relevance of having knowledge about the blood group systems among different ethnic groups in any population is enormous. The types of information obtained from the findings are useful for genetic information, genetic counseling, medical diagnosis, general and physiological wellbeing of individuals in a population.  It is, therefore, imperative to have information on the distribution of these blood groups in any population group that comprise different ethnic groups.
In India, few studies have been carried out on the distribution of blood groups in various endogamous populations , but dearth of data in West Bengal.  This study was, therefore, designed to provide the information on the distribution of ABO and Rh blood groups among the Bauri pregnant women of Bankura, West Bangal.
The Bauris are a comparatively well-known sizeable caste group in West Bengal. The total Bauri population in West Bengal is 1,091,022 constituting 5.9% of the total scheduled caste population of the state. Bauri is a cultivating, earth-working, and palanquin-bearing caste, whose features and complexion suggest that they may be of non-Aryan descent. Bauris profess to be Hindus of the Sakta sect, but in Western Bengal, at any rate, their connection with Hinduism is of the slenderest kind, and their favourite objects of worship are Manasa, Bhadu, Mansingh, Barpahari, Dharmaraj, and Kudrasini. The socioeconomic status and the literacy rate of Bauris are very low. 
Pregnant Bauri women attending the Bankura Sammilani Medical College and Hospital (BSMCH) formed the study population. During the period between June 2010 and August 2010, 246 blood samples were studied. ABO and Rh blood groupings of the subjects were carried out by standard tile techniques with appropriate positive and negative controls using one drop of whole blood mixed with one drop of appropriate anti-sera and rocked gently. The used anti-sera were obtained from Tulip Diagnostics Pvt. Ltd., Goa (India). In case of doubt, the test was examined under a microscope, or the results were confirmed by reverse grouping using known group A and B red cells.  Data on the frequency of ABO and Rh-D blood groups were reported in simple percentages.
The distribution of the ABO and Rh blood groups among the Bauri population of Bankura district is depicted in [Table 1]. The most frequently occurring blood group in Bauri population was B (37.4%), followed by blood group O (29.67%) and A (23.58%). While group AB was the least encountered phenotype with a frequency of < 10% among the samples studied. The phenotypic frequencies with respect to ABO system in the present study can be shown as B > O > A > AB. The prevalence of the ABO phenotypes linked with Rh phenotype was B± (36.18%), followed by O± (29.27%), A± (22.76%), and AB± (8.94%). The lowest prevalence was that of AB-(0.004%).

Distribution of ABO and Rh(D) blood groups among Lodha tribe in Midnapore district of West Bengal was analysed and it was observed that incidence of group A was maximum and incidence of group AB was minimum; 99.5% of the subjects were 'Rh' positive.  However, in a study on the distribution of ABO and Rh among the Brahmin and Kushwaha populations of Jhansi Uttar Pradesh the prevalence recorded is O >B > A > AB.  Our studies are in agreement with respect to ABO and Rh systems with the general formula B > O > A > AB, in a previous study conducted in the Banjara backward caste of Maharashtra.  Jaff  reported that the most prevalent blood group was O (37.16%) and the least prevalent was AB (6.53%) and the majority were Rh positive (91.73%) in the Kurdish ethnic group of Iraq.  These differences with the present study may be due to different geographical locations different ethnicities.
The present study showed that there was a real preponderance of the blood group B over the blood groups O, A and specially AB as well as Rh(D) positive over Rh(D) negative.
