Isolation and quantification of microorganisms from some common milk products within Dhaka city, Bangladesh

Stamford Journal of Microbiology (2016)

M Malek Jasmin Akter Tasnia Ahmed Md Aftab Uddin

While milk is well known to be a balanced diet with its high nutritional values, conversely milk and milk products may serve as potential substrate for the growth and proliferation of a range of microorganisms which in turn fatally influences mass public health. Current study attempted to examine the likelihood of microbial contamination within some common milk products consumed by the locality of the city of Dhaka, Bangladesh. All samples exhibited the presence of bacterial and fungal contamination within a range of 102-104 cfu/mL and 102-103 cfu/mL, respectively. Among specific pathogens, Staphylococcus spp. was noticed to be the predominant ones and was recovered from 9 samples out of 20 samples in a range of 102-103 cfu/mL. Klebsiella spp. and Vibrio spp. were found within 6 and 9 samples, respectively. Products were also found to be contaminated with Vibrio spp. Study of antibiotic susceptibility test revealed that all the pathogenic bacteria were resistant against most of the commonly used antibiotics of which several isolates showed multi-drug resistant (MDR) trait. Therefore, the presence of pathogenic bacteria with the drug-resistance property in tested milk and milk products overall imparted the necessity of maintaining standardized hygienic handling and processing means for better management of public health.Stamford Journal of Microbiology, Vol.5(1) 2015: 13-17

Microbiological profile of potato samples collected from Bangladesh Agricultural Research Institute (BARI) and notification of anti-bacterial traits

Stamford Journal of Microbiology (2015)

M Malek Mrityunjoy Acharjee Tasmina Rahman

Present study assessed the microbiological quality of different categories of consumable potatoes collected from Bangladesh Agricultural Research Institute (BARI), the largest multi-crop research institute of the country conducting research on a large number of crops. Five samples each from 15 categories of potato samples (Lara, Quincy, Cardinal, Esprit, Meridian, Lady Rossetta, Astrix, Soikat, Red potato, White potato, Russet potato, Yellow flesh potato, Sweet potato, Purple potato and Petiets potato) were subjected to microbiological analysis through conventional culture followed by the biochemical identification tests of the pathogens. A huge array of bacterial and fungal contamination was noticed within a range of (~108 cfu/g) in almost all samples studied. Among the bacterial pathogens, Escherichia coli and Staphylococcus spp. were found to be predominant. Study of antibiogram revealed that most of the isolates were resistant against the commonly used one or multiple antibiotics. Finally, all the samples were also examined for presence of any anti-microbial activity against different pathogenic bacterial species. Astrix potato samples exhibited antimicrobial activity against Shigella spp and the Russet potato samples exhibited the anti-bacterial activity against Staphylococcus spp. DOI: http://dx.doi.org/10.3329/sjm.v3i1.22747 Stamford Journal of Microbiology, Vol.3(1) 2013: 21-25

Assessment of survival of pathogenic bacteria in fresh vegetables through in vitro challenge test

International Journal of Food Contamination (2015)

Rashed Noor M Malek Shohanur Rahman Monirunnessa Meghla Mrityunjoy Acharjee

Being led by the previous observation of bacterial growth and survival in the fresh-cut tomato, carrot, lettuce and cucumber, current investigation further attempted to emphasize on the growth and consequent endurance of the pathogenic bacteria within chili (Capsicum frutescens), onion (Allium cepa), capsicum (Capsicum annuum) and coriander (Coriander sativum) collected from local markets. Samples were primarily made free of contaminating bacteria and then subjected to inoculation by eight (8) test bacteria; i.e., Eshecrichia coli, Klebseilla spp., Vibrio spp., Bacillus spp., Salmonella spp., Listeria spp., Pseudomonas spp. and Staphylococuus spp. and kept at room temperature. Bacterial growth pattern was observed up to 15 days and in general, the bioburden was noticed to be reduced up to 3 log from the initial load of the inoculam in all the samples used. The chilli and onion samples were found to reduce the bacterial load more effectively than the capsicum and coriander samples. The survival of the pathogens in the vegetable samples raises the necessity of maintaining proper sanitary condition during handling and storage of fresh vegetables.

Effect of Radiation Sterilization on the Physicochemical Properties and Microbial Load of Amoxicillin Tri-Hydrate Powder

Bangladesh Journal of Microbiology (1970)

Md. Humayun Kabir Anisur Rahman Khan Marufa Zerin Akhter M Malek Nazmul Alam Chowdhury

Amoxicillin tri-hydrate powder was irradiated at different doses of gamma radiation, and the subsequent changes in terms of physicochemical properties and potency were evaluated. A dose of 0.5 Mrad was found to be enough to sterilize the powder, which had an initial bacterial count of 6.2 x 101 cfu/ml. The original snow-white colour of the powder changed to light brown upon irradiation doses over 2.5 Mrad. The pH decreased upon increase of radiation dose. The iodometric titration assay showed only a little variation in potency (about 1-4%) of the test materials after irradiation. High performance liquid chromatography (HPLC) analysis of irradiated amoxicillin tri-hydrate powder showed no marked loss of potency by irradiation even up at a dose of 10.0 Mrad. No degradation product and extra peak was found at this high dose. The results indicated that dried powder of amoxicillin tri-hydrate is stable after sterilization by irradiation.Keywords: Amoxicillin tri-hydrate, Irradiation, RadiosterilizationDOI: http://dx.doi.org/10.3329/bjm.v23i2.886Bangladesh J Microbiol, Volume 23, Number 2, December 2006, pp 165-167
