Several microorganisms have been employed as research tool to amend various parameters of industrial prominence. The current research article is from the context of significance emphasizing on the silk industry. The research article has focused on the impact of <em>Burkholderia cepacia</em> which is an endophytic bacterium on the silk worm and the affirmative aspects were recorded. The research work included the inoculation of the bacterium with the silk worm which has resulted in enhanced production of silk from the inoculated lot. In addition, the research has also demonstrated higher activity of protease and amylase in inoculated lot when compared to control population. The results obtained have substantiated the practical aspect of the research.</p> V.

Radula (Prosobranchia:Potamididae) Sold in Markets in Nasarawa State, Nigeria <p>The aim of this study was to determine the antibiogram of bacterial isolates from <em>Tympanotonus fuscatus</em> var. radula sold in markets in Nasarawa State. Nigeria. Samples of <em>Tympanotonus fuscatus var</em>. radula (periwinkles) were bought from soup ingredient sellers at different sale locations in Keffi, Masaka and Orange markets and were analyzed using standard bacteriological methods. The bacterial isolates were identified using morphological, cultural and biochemical techniques. The total bacteria count varied from 1.18–3.20 x 10<sup>8 </sup>CFU/g for the raw samples while the total bacterial count for the boiled samples varied from 0–1.57 x 10<sup>8 </sup>CFU/g. Periwinkle samples with shells from Masaka market had the highest bacterial load with a mean total bacterial count of 2.94 x 10⁸ CFU/g and mean total coliform count of 2.80 x 10⁶ CFU/g. Raw periwinkle samples with shells had a higher bacterial load than samples without shells. There was also a drastic reduction in the bacterial load in the periwinkle samples after boiling under laboratory conditions. The bacteria isolated were <em>Bacillus </em>spp.<em> and Staphylococcus aureus </em>were the Gram-positive bacteria isolated.<em> Enterobacter </em>spp.<em>, Escherichia coli, Salmonella </em>spp.<em>, Pseudomonas </em>spp.<em>, Serratia </em>spp.<em> and Proteus </em>spp<em>. </em>The most frequently occurring gram positive bacteria was <em>Escherichia coli </em>with an isolation frequency of 6(24%)<em>, </em>the least frequently occurring was <em>Bacillus </em>spp., 8(32)%. Antibiotic susceptibility test showed that all the gram negative organisms exhibited sensitivity to ciprofloxacin: <em>Escherichia coli </em>(32 mm),<em> Enterobacter </em>spp. (41.5 mm),<em> Proteus </em>spp. (40.0 mm),<em> Salmonella </em>spp. (37.0 mm),<em> Serratia </em>spp. (26.0 mm),<em> Pseudomonas </em>spp. (23.0 mm). All the gram negative organisms showed marked resistance to vancomycin: <em>Escherichia coli </em>(12.0 mm),<em> Enterobacter </em>spp. (10.0 mm),<em> Proteus </em>spp. (11.0 mm),<em> Salmonella </em>spp. (5.0 mm),<em> Serratia </em>spp. (10.0 mm) and<em> Pseudomonas </em>spp. (4.5 mm).</p> U.
