  A study was conducted to find association between serum retinol level, blood haemoglobin level and Body Mass Index (BMI) of rural adolescent children (aged 10-17 years) having or not having eye changes. The study was carried out through a cross sectional survey on 906 adolescents from 803 households, sampled consecutively from four purposively selected villages of Rupganj Upazila (sub-district) under Narayanganj district, Bangladesh. An appropriate questionnaire was developed to obtain information on age, sex, height, weight, housing condition, sanitation and educational qualification of both the adolescents and their parents. Among 906 adolescents (47% male and 53% female), 2.1% (19) had eye changes that are known to occur due to Vitamin A deficiency (e.g., retinal, conjunctival and corneal changes). Eleven (57%) of them were male and 8 (42%) were female. Of the 19 adolescents who had eye changes, 9 (42%) had serum retinol level below the cut-off value of 20 μg dL-1, 90% had BMI lower than 18.5 kg m-2 (i.e. suffering from chronic energy deficiency) and 100% were anaemic (Hb level <115 g L-1). These figures were 25, 66 and 72%, respectively, in adolescents who had no eye changes. These data show strong association of malnutrition and anaemia with eye changes in adolescents. The national vitamin A supplementation programme should be extended from under-6 year old children to the adolescent population, who are yet another vulnerable group.

  Using monoclonal antibodies (MAbs), the coagglutination test detected Vibrio cholerae O1 and O139 serogroups both in the bacterial culture and in the stool specimens. Detection of V. cholerae O1 and O139 from the cultures of different V. cholerae O1 and O139 strains and non-O1 and non-O139 strains showed a specificity of 100%, a sensitivity of 100% and a 100% positive predictive value. Among the 146 stool samples tested by the coagglutination test, 36 were culture positive, but 33 were coagglutination test positive showing a specificity of about 92%. All the culture negative samples were negative in the coagglutination test indicating a specificity of 100%.

  Studies were carried out on monoclonal antibodies (MAbs) ICL12, ICL26 and ICL31, which had been produced against Vibrio cholerae O1 and O139. These MAbs of IgG isotypes were used for the development of the Immunomagnetic Separation together with Polymerase Chain Reaction (IMS-PCR). Using MAbs ICL12, ICL26 and ICL31, the IMS-PCR procedure detected V. cholerae. in the pure cultures and in the stool samples. The detection limit of this method was 101 cfu mL-1 for V. cholerae. O139 while for the detection of V. cholerae. O1 Ogawa it was 102 cfu mL-1 and for V. cholerae. O1 Inaba it was 103 cfu mL-1. Of the 25 fresh stool samples tested, 15 were culture positive but 18 were IMS-PCR positive. Of the 55 frozen stool samples tested, 46 were culture positive but only 34 were IMS-PCR positive. However, when the 71 stool samples were frozen with Bovine Serum Albumin (BSA) added subsequently tested, 37 were culture positive while 49 were IMS-PCR positive. This showed that when stools were frozen with added BSA, the IMS-PCR procedure was much more specific and sensitive than the conventional culture method.
