ABSTRACT
783 blood samples for the study of distribution of ABO blood groups and sickle cell haemoglobin in relation to malaria, from both the sexes of Muslim and Christian populations of Kheda district were screened. 414 blood samples from male individuals were screened for G-6-PD deficiency. High frequency of G-6-PD deficiency was observed in Christians (5.9%) and low in Muslim (1.8%) population, whereas sickle cell haemoglobin in Muslim population was 1.5% and absent in Christians. Blood group B was dominant in both the communities. Significant association of ABO polymorphs with P. falciparum and total malaria cases was observed.

Four strains of Bacillus sphaericus, 1593, 2362, 9001 and 9002, B. thuringiensis H-14 and B. thuringiensis neoleonensis were tested for sensitivity against 18 antibiotics. The results revealed that all the four strains of B. sphaericus are resistant to colistin, nalidixic acid, polymyxin B and streptomycin. However, B. thuringiensis H-14 was resistant to 9 antibiotics, viz. ampicillin, cephalexin, carbenicillin, co-trimoxazole, colistin, cloxacillin, penicillin, nitrofurantoin and polymyxin B whereas B. thuringiensis neoleonensis was found to be resistant to 8 antibiotics. These results may help in isolation of potential and resistant mosquito pathogenic bacteria.

Sampling of anophelines from six villages of Kheda district, Gujarat was done using four different methods viz. indoor resting, outdoor resting, bovine bait trap and immature collections. A total of 113,487 specimens representing 17 species were collected. An. subpictus (66.51 per cent) was most abundant species followed by An. culicifacies (14.12 per cent) and An. tessellatus (5.24 per cent). Bovine bait collections were found most productive yielding maximum species and highest number of anophelines per unit of collection efforts. Indoor resting collections yielded poorest diversity and greater number of specimens per unit of collection effort than outdoor resting collections. Maximum diversity was observed in outdoor collections. Most of the species exhibited unimodal prevalence.
