Considering their serious clinical significance, the study investigated the prevalence of MDR-ESBL-producing Salmonella strains isolated from raw chicken meat in Southern Nigeria. A total of 240 raw chicken meat were sampled and the recovered Salmonella strains were characterized for MDR and ESBL-genes using Kirby Bauer disc diffusion and molecular techniques. Of the 52 confirmed Salmonellaenterica serotypes, 67.31% (35/52) were Salmonella entericasubsp. entericaserovar Typhimurium, 32.68% (17/52) were Salmonella entericasubsp. entericaserovar Enteritidis, 78.85% (41/52) were ESBL-producer and 88.45% (46/52) multidrug resistant. Ampicillin (96.15%) and gentamycin (40.39%) were the most and least antibiotics. The most prevalent MDR-ESBL-genes were bla CTX-M (92.68%), followed by bla SHV genes (68.29%) and bla TEM(31.71%). This study showed that Salmonella serotypes with high ESBL-genes and MDR were prevalent in raw chicken meat vended in southern Nigerian markets. \u0000Bangladesh J. Sci. Ind.

In this context, sour yoghurt sample was collected from local market in Rajshahi for molecular identification and characterization of Bifidobacterium sp. with promising antagonistic activity against pathogenic bacteria. Isolation was done on Luria broth agar media for molecular identification and revealed that isolated bacterium showed 90% similarity with Bifidobacterium sp. Antibiotic sensitivity test result revealed that isolated Bifidobacterium sp. was sensitive to erythromycin, kanamycin, gentamycin, tetracycline, ciprofloxacin, doxycycline out of eleven commercially used antibiotics. Moreover, antagonistic activity of Bifidobacterium sp. was evaluated in our present study against four pathogenic bacteriathrough disc diffusion method. Bifidobacterium sp. had relatively strong antagonistic effect (inhibition zone ≥15 mm) against Salmonella sp. with 16mm and 19mm zones of inhibition at doses of 150 and 200 μg/disc, respectively. Similarly, the isolate showed strong growth inhibitory activity against Acinetobacter sp. and E. coli with inhibition zone of 17 mm and 16 mm at dose of 200 μg/disc while moderate growth inhibitory activity was observed against Aeromonas sp. at applied four doses. Furthermore, present investigation showed that the isolated Bifidobacterium sp. had the utmost effect against Salmonella sp. and exhibited growth inhibition of understudy pathogens in such pattern Salmonella sp.>Acinetobacter sp.> E. coli> Aeromonas sp.\u0000Bangladesh J.

In the present investigation, salt stress was tested with three rice (Oryza sativa L.) varieties/genotypes viz. Pokkali, Sunduri Samba, and Khasa with three levels of salinity (0, 6, and 9 dSm-1). In the investigation,growth, morphology, and ionic status in roots, stem, and leaf were observed under pot culture with three replicates in each treatment. The results of the experiment revealed that salt stress decreased in growth attributes namely, root dry matter, shoot dry matter, total dry matter and root: shoot ratio. Sunduri Samba showed higher values, but Khasa the lowest. Mineral ion content especially the cation in the plant tissue namely Na+, K+, Ca2+, Mg2+ differed significantly due to salt stress as well as the K+/ Na+ ratio decreased in root and shoot due to salinity. Sunduri Samba maintained quite higher K+/Na+ than the susceptible genotype. Due to salinity, different growth characteristics and K+ concentrations decreased but Na+ concentration increased. Here the tolerant genotype Sunduri Samba accumulated higher amounts of K+ than the susceptible genotype Khasa and altered the ionic ratios through distribution of Na+ ion in shoot. Bangladesh J. Sci.

In the present study, a pot-experiment was conducted using a Boro rice variety (BRRI dhan-29) in two geomorphologically different soils from Holocene floodplains and Pleistocene terraces, in which silicon-rich fresh rice husk (FRH) and rice husk ash (RHA) were applied, as silicon fertilisers, in the soils at the rate of 1% (w/w) of rice residue:soil.In the Holocene floodplain soils, the application of FRH was found to decrease arsenic in grain, husk and straw by 42, 56 and 51%, respectively, whereas the soil incorporation of RHA decreased arsenic in grain, husk and straw by 26, 37.5 and 36%, respectively. In the Pleistocene terrace soils, the application of FRH reduced the grain, husk and straw arsenic by 38, 38 and 44%, respectively, whereas the RHA decreased the grain, husk and straw arsenic by 26, 30 and 29%, respectively. Fresh rice husk was found to be more effective in alleviating arsenic accumulation in rice than RHA. In both the Holocene floodplain and Pleistocene terrace soils, the grain concentrations of calcium, phosphorus, silicon, and zinc were found to be increased with the decrease of arsenic in the grain due to the use of FRH and RHA. The present study suggests that silicon-rich rice husk residue scan be used as silicon fertilisers to reduce arsenic accumulation in rice in Bangladesh.\u0000Bangladesh J. Sci. Ind.

As a poorly water-soluble drug its absolute bioavailability is very low. To increase the water solubility as well as oral bioavailability, different hydrophilic carriers were used in different ratios (1:0.5, 1:1 and 1:2) to prepare reproducible binary and ternary solid dispersion formulations of ATV by simple physical mixing (PM) and fusion or melting technique. In vitro dissolution studies results revealed that in all cases, the cumulative percent drug release from ATV ternary SD formulations were greater than binary formulations, some marketed products and pure ATV powder. The order of the carriers in enhancing the drug release was found as kollidon 90F > pregelatinized starch > lutrol> kollidon 12F (99.1%, 98.8%, 96% and 95% respectively) for ternary SD formulations whereas pure ATV powder and marketed products showed cumulative percentage release 70.8%, 68.9% (B1) and 73.1% (B2), respectively. The best-out performed ternary SD formulation ATV:Kollidon 90 F (1:2) were further characterized using FT-IR and SEM. SEM analyses indicated conversion of crystal drug to amorphous form and FT-IR data suggested that little or no interaction between the drug and polymer.\u0000Bangladesh J. Sci. Ind.
