We describe the isolation and identification of di-n-hexyl phthalate, a new marine pollutant found in Atlantic herring (Clupea harengus harengus) and Atlantic mackerel (Scomber scombrus). This compound was isolated from extracted lipids by a combination of gel permeation, high performance liquid and column chromatography, and selective precipitation of impurities. Conclusive proof of its structure was obtained from gas chromatographic–mass spectrometric analysis and proton nuclear magnetic resonance spectroscopy. The concentrations of di-n-hexyl phthalate (17–27 μg/g wet weight), which is not a major industrial phthalic acid ester, far exceeded those of dibutyl and di-2-ethylhexyl phthalates, the major industrial phthalic acid esters. Thus the possibility of selective bioaccumulation of DHP in herring and mackerel was indicated. This finding is important in view of the paucity of toxicological information concerning this compound.Key words: phthalic acid ester, di-n-hexyl phthalate (DHP), analysis, mackerel, herring, marine fish, pollution

Isolation and identification of post operative hospital acquired infection was carried out from July 2008 to December 2008 in Holy Family Red Crescent Medical College Hospital (private hospital). The major pathogen of wound infection was E. coli. A total; of 120 samples were collected from the surrounding environment of post operative room like floor, bed sheets, instruments, dressing materials, catheter, nasogastric and endotracheal tube. E. coli (40%) was the predominant organism followed by S. aureus (24%). DNA fingerprinting analysis using pulsed field gel electreopheresis of XbaI restriction digested genomic DNA showed that clonal relatedness between the two clinical nd environmental isolates were 100%.DOI: http://dx.doi.org/10.3329/bjmm.v6i2.19369 Bangladesh J Med Microbiol 2012; 06(02): 7-10

Duck plague (DP) is the most important infectious disease of geese, ducks and free-ranging water birds. The present study was conducted to determine the prevalence of duck plague virus followed by isolation and identification. For these purposes, a total of 155 cloacal swabs samples were collected randomly from duck of different haor areas of Bangladesh including 45 (41 surveillance and 4 clinical) samples from Netrokona; 42 (40 surveillance and 2 clinical) samples from Kishoregonj; 30 samples from Brahmanbaria and 38 samples from Sunamganj. The samples were processed and pooled (1:5 ratio) for initial screening of target polymerase gene of duck plague virus by polymerase chain reaction (PCR) method. All the samples of a positive pool were then tested individually for identifying the individual positive samples. The result showed that out of 155 samples, 41 (26.45%) were found positive in which 17 were from Netrokona, where 15 (36.58%) were from surveillance samples and 2 (50%) were from clinical sample; 16 were from Kishoregonj, where 14 (35%) were from surveillance samples and 2 (100%) were from clinical sample; 2 (6.6%) were from Brahmanbaria and 5 (13.15%) were from Sunamganj. These positive samples were inoculated into 9-10 days embryonated duck eggs (EDE) through chorioallantoic membrane (CAM) route for the isolation of virus. The EDE died earlier was also chilled, and in a similar way, the CAMs were collected and again performed PCR for id entification of virus. Out of 41 PCR positive samples, 26 samples were isolated and reconfirmed by PCR. Subsequently, DPV was isolated in primary duck embryo fibroblasts cell culture and confirmed by observing cytopathic effect (CPE). Bang. J. Livs. Res. Vol. 26 (1&2), 2019: P. 73-78
