Study of plasmid linked resistance pattern of MDR enterobacterial pathogens

Ten multiple drug resistant enterobacterial pathogens were isolated from common sources of human consumption and were subjected to plasmid isolation. The multiple drug resistant (MDR)(write full abbreviation) isolates collected in the present study indicated the presence of plasmids of almost identical size of approximate 60 kb conferring resistance towards multiple antibiotics. An opportunistic pathogen Pseudomonas […]

Comparative determination of trace elements from Allium sativum, Rheum australe and Terminalia chebula by atomic absorption spectroscopy

In present study the bulb of Allium sativum, root of Rheum australe and fruit of Terminalia chebula were selected for trace elements analysis by Atomic Absorption Spectrophotometer. The plant samples were digested with concentrated Nitric acid (HNO3) and concentrated Perchloric acid (HClO4). The analysis for trace elements in the sampled plants indicated that Sodium, Potassium, […]

Allelopathic potential of Diospyros kaki L. against Triticum aestivum L., Brassica compestris L. and Trifolium alexandrinum L.

Allelopathic studies of Diospyros kaki L. were conducted by using aqueous extracts from leaves, bark, litter and mulching in various experiments. It was observed that the germination, radical growth, plumule growth, no. and growth of seminal roots, fresh weight and dry weight of Triticum aestivum L and Brassica campestris L. and Trifolium alexandrinum L. were […]

Taxonomic Studies on the Family Solanaceae in the Rajshahi University Campus

Taxonomic investigation of the family solanaceae growing through out the Rajshahi University campus was carried out. A total of 8 (eight) species under 4 (four) genera of the family Solanaceae were collected and identified by comparing with correctely identified herbarium sheets deposited at Rajshahi University Herbarium and checking with taxonomic literature ( khan and Mia, […]

In vitro controlling of selected human diarrhea causing bacteria by clove extracts (Syzygium aromaticum L.)

Antibacterial activity of clove extracts (Syzygium aromaticum L.) was proven against five diarrhea causing bacteria. This was further confirmed when compared with commonly used three commercial antibiotics (ciprofloxacin, tetracycline and erythromycin) as a positive control. Significant differences (P<0.0001) were observed in the effect of the antimicrobial agents (clove extracts and antibiotics), and in the sensitivities […]
