The study was conducted to adopt PCR based technique for identification of species origin from meat samples of cattle and buffalo using mitochondrial cytochrome b (Cyt b) gene fragment. A total of 42 ear tissue and meat samples were collected from different slaughterhouses and farms of Mymensingh, Bogra and Rangpur districts and stored in 96% ethanol at room temperature. Genomic DNA was extracted from all samples using GeNet Bio genomic DNA isolation kit. The average DNA yield of considered samples was found 204.57 ng/?l where the purity ranged from 1.82–1.99. Two (2) pair species-specific primers were used to amplify Cyt b gene fragments of 472 bp and 124 bp for cattle and buffalo, respectively. The PCR results revealed different species specific amplified fragments which could discriminate between cattle (472 bp) and buffalo (124 bp) species precisely from pure and mixed samples of those species. This study suggests an accurate molecular technique for identification of cattle and buffalo species meat origin and differentiates species present in adulterated meat samples. In conclusion, this DNA based technique could be utilized for prevention of malpractice in slaughterhouse and chain shops and thereby to protect consumer’s right.Asian J. Med. Biol. Res.

The present study was conducted to discriminate between sheep and goat species meat origin utilizing mitochondrial cytochrome b (Cyt b) gene fragment. A total of 46 ear tissue and meat samples were collected from different slaughterhouses and farms of Mymensingh and Rangpur districts. Genomic DNA was extracted using GeNet Bio DNA isolation kit and DNA concentration and purity was quantified by NanoDrop spectrophotometer. Two pairs species specific primer were used to amplify Cyt b gene fragments. Selected primers were highly conserved across the breed within a species and worked well with the species of indigenous goat and sheep resulting similar size of the amplicons 330 and 585 bp respectively. The duplex PCR condition would enable to detect adulteration from goat and sheep mixed samples which revealed by two precise bands (330 and 585 bp) in a single reaction. This study suggests an accurate molecular technique for identification of sheep and goat meat species origin and differentiates species present in adulterate meat samples. In conclusion, this DNA based marker could be used for prevention of fraudulent practice in slaughterhouse and chain shops in Bangladesh.Bang. J. Anim. Sci. 2016. 45 (2): 41-45

Although the use of electron microscopy and its varied methodologies is not usually associated with ecological studies, the types of species specific information that can be generated by these techniques are often quite useful in predicting long-term ecosystem effects. The utility of these techniques is especially apparent when one considers both the size range of particles found in the aquatic environment and the complexity of the phytoplankton assemblages.The size range and character of organisms found in the aquatic environment are dependent upon a variety of physical parameters that include sampling depth, location, and time of year. In the winter months, all the Laurentian Great Lakes are uniformly mixed and homothermous in the range of 1.1 to 1.7°C. During this time phytoplankton productivity is quite low.

SummaryThe purpose of this study was to develop specific and sensitive immunoassays to detect early indices of hypercoagulability in the rat. Rat platelet factor 4 (rPF4) and rat fibrinopeptide A (rFPA) assays, tools for the detection of activation of platelets and coagulation respectively, were designed using antibodies raised against purified rPF4 and against synthetic rFPA. The relevance of these new assays and of the commercially available ELISA kit for thrombin-antithrombin III (TAT) complexes was demonstrated in a rat model of a prethrombotic state induced by intravenous infusion of varying doses of thromboplastin (90 to 2400 μl/kg/h). In this model, the immunoassays allowed simultaneous detection of low levels of rFPA and rPF4 which were correlated with fibrinogen and platelet consumption and TAT generation and further proved to be of higher sensitivity than the classical methods of platelet count or measurement of fibrinogen levels. Plasma concentrations of rFPA, rPF4 and TAT were dependent on infusion time and thromboplastin dose, while hirudin (1 mg/kg) prevented their appearance. Thus the new specific immunoassays for rPF4 and rFPA and the commercial human TAT assay represent useful tools for pathophysiological studies or the screening of antithrombotic drugs in rats.
