Osmotic pressure (Π) induces membrane tension in cells and lipid vesicles, which may affect the activity of antimicrobial peptides (AMPs) by an unknown mechanism. We recently quantitated giant unilamellar vesicles (GUVs) due to Π under physiological conditions. Here, we applied this method examine effect on interaction AMP magainin 2 (Mag) with single GUVs. Under low values, Mag induced formation nanometer-scale pores, through water-soluble fluorescent probe AF488 permeates across membrane....
Abstract Due to the stochasticity of metabolic reactions and cell cycles bacterial cells, it is necessary examine antibacterial activities antimicrobial compounds (AMCs) such as antibiotics peptides (AMPs) at single-cell level. Here, we review recent studies bactericidal AMCs First, discuss investigations interaction various AMPs with single monitored in real time using optical microscopy. This strategy provides information on AMP-induced membrane damage cells [e.g. onset (CM) outer cells]....
The antimicrobial peptide (AMP) derived from lactoferricin B, LfcinB (4-9) (RRWQWR), and lissamine rhodamine B red-labeled (Rh-LfcinB (4-9)) exhibit strong activities, they can enter Escherichia coli cells without damaging the cell membranes. Thus, these peptides are cell-penetrating (CPP) -type AMPs. In this study, to elucidate effect of membrane potential (Δφ) on action CPP-type AMP, Rh-LfcinB (4-9), we investigated interactions with single E. spheroplasts containing calcein in cytosol...
Following an incidence of freshwater prawn Macrobrachium rosenbergii postlarvae (PL) mortality in hatcheries summer 2012, samples from dead PL, rearing water and feed two south-west coastal districts Bangladesh were collected to isolate, identify characterize the agents causing PL mortality. Antibiogram profile sixteen randomly selected bacteria, isolated that grew on TCBS, 20 different antibiotics belonging 12 major groups revealed drug resistance pattern varied moderate (56% drugs:...
Antimicrobial peptides (AMPs) inhibit the proliferation of or kill bacterial cells. To measure these activities, several methods have been used, which provide only average value many Here, we report development a method to examine antimicrobial and bactericidal activities AMPs at single-cell level (i.e., analysis) apply this strategy interaction an AMP, magainin 2 (Mag), with Escherichia coli Using method, monitored single cells on agar in microchamber measured distribution number each...
Diospyros malabarica is a well known flowering plant indigenous to Indian subcontinent which used in folklore medicine for several purposes. Our study designed assess the neuropharmacological and antibacterial efficacy of ethyl acetate extract D. seeds. The behavioral anxiolytic activities were assessed by using open field (OFT), hole cross (HCT), elevated plus maze (EPZ), board (HBT), light dark test (LDT); antidepressant through forced swimming (FST) tail suspension (TST). Antimicrobial...
Vibrio parahaemolyticus organisms cause acute gastroenteritis in humans. These bacteria are natural inhabitants of both marine and estuarine ecosystems. In the present study, we investigated effectiveness a non-selective enrichment sediment samples with sodium chloride prior to selective alkaline peptone water for better recovery V. parahaemolyticus. Sediment were collected or without 1% NaCl from river Buriganga, located besides Dhaka city about 400 km away Bay Bengal, estuary Karnaphuli...
A significant limitation to flourish poultry industry in Bangladesh is the emergence of multidrug resistance pathogenic bacteria like Salmonella spp. due uncontrolled use antibiotics for disease treatment. An alternative could be application probiotics. About 120 cloacal-swabs from birds were investigated, seventy two (72) isolates and twenty (22) lactic acid (out 50)were identified respectively by cultural, morphological biochemical tests presumptively. Antibiotic sensitivity test was...
