...robial contamination and biofilm formation in food industries pose a threat to human health worldwide. With the increased use of antibiotics in food industry, the problem of bacterial resistance is emerging, hence leading to serious health issues. Among 24 strains isolated from Shaukat Banaspati Ghee industry (Grw) and Shezan foods (pvt) Ltd, Lahore, Pakistan food industry, 10 highly antibiotic resistant strains were subjected to morphological, physiological a...

...nment and to check their biofilm forming ability under nickel stress. Our previous results showed that these bacteria are capable of producing proline, glycine betaine, choline and other osmolytes under NaCl stress. On the basis of those results it is hypothesized that this osmolyte production ability may help them in nickel resistance under Ni salt stress. This study was centered on assessing the adherence, motility, hydrophobicity, aggregation and

The micro well cytotoxicity assay against Artemia salina showed the cytotoxicity of the extracts in the range of 10-35%...

bacterial motility. Present study determined swimming, swarming, and twitching
motilities in response to different physiochemical factors. Twenty-two
morphologically different bacterial strains were collected from a drain of sewage
water located in the vicinity of Jinnah hospital Lahore, Pakistan. Six biofilm forming

The antibacterial activity of capsaicin was evaluated by the minimal bactericidal concentration, change of pH in the first 12 h and OD values of biofilms. Besides, fluorescent images of exopolysaccharides and living bacteria of Streptococcus mutans were measured with confocal laser scanning microscopy (CLSM). In our study, capsaicin showed an outstanding performance in the inhibition ...

D. vulgaris was treated with various concentrations (5, 40, 80 and 100µM) of salicylidene acylhydrazide and 5-15 µM of proteases (proteinase K, trypsin, and chymotrypsin). Concentration dependent decrease was observed after 72 hours in biofilm formation of ...

...sent study aims to check biofilm formation and auto aggregation potential of the bacteria associated with cockroaches. For this purpose, cockroaches were captured from house sewerage and two bacterial strains CXA1 (Planomicrobium chinense) and IM2 (Alkaligenes faecalis) were isolated from external surface and rectum portion of cockroach, respectively. Bacterial autoaggregation started increasing after 1 h of culture incubation and reached maximum...

Current study was planned to detect bpSA from dairy milk, confirmation of presumed risk factors, and comparative analysis of antibiogram of bpSA and nbpSA at various cadre. Milk samples (n=250) from catt...

The purposive sampling technique was applied to collect n=200 milk samples from different regions of goat populated areas of district Faisalabad-Pakistan. Using surf field mastitis test, collected milk samples were screened for subclinical mastitis at the spot for subsequent identification of p...
