  The study was done for a complete year on monthly basis and the differences on the various parameters selected were measured. Significantly higher number of fungi and bacteria were recorded in non-roadside soil then the effected roadside soil. Rate of soil respiration, enzymes activity also followed a similar trend. Other physicochemical characteristics as soil moisture, soil pH, soil temperature and soil carbon revealed similar variations in two conditions. Microbial population and enzyme activities like dehydrogenase, urease and phosphatase were positively correlated (p<0.05) to the edaphic properties of the soil. Microbial populations, soil respiration, enzymes activity and other physicochemical characteristics were determined from the sub-tropical forest soils of roadside (disturbed) and non-roadside (undisturbed) conditions to compare and the adverse effects of anthropogenic activities and roadside vehicular pollution in the busy national highway. The study site is devoid of human settlement and was once a pristine environment prior to the construction of highway through the forest. An average of 10,000 to 12,000 vehicles plies through the road per day.

  A cross-sectional study of different portions of chicken raw meat samples from the local meat markets of North East India was carried out during October 2007 to September 2008 on a total of 110 collected samples using Plate Count Agar, Lactose broth, Violet red bile glucose agar, Brilliant green bile lactose broth, Eosin methylene blue agar, MacConkey agar, Salmonella shigella agar, Bimuth sulphite agar, Xylose lysine deoxycholate agar, Nutrient agar and Potato dextrose agar. Of the 74 different bacteria detected, the bacterial population incidence was highest in chicken wings (83.5%), followed by chicken tails (77%), breasts (70%), thighs (69%) and gizzard (38%). Frequent organisms in the samples were Enterococcus faecalis (100%), Enterobacter aerogenes (100%), Escherichia coli (98%), Klebsiella pneumoniae (98%), Micrococcus sp. (69%) and Candida sp. (80%). The other organisms isolated were Klebsiella oxytoca (35%), Citrobacter sp. (52%), Proteus sp. (49%), Staphylococcus aureus (20%), Staphylococcus epidermidis (20%), Yersinia enterocolitica (23%), Listeria monocytogenes (15%), Shigella dysenteriae (1.8%), Salmonella tyhpi (20%), Bacillus cereus (10%), Aeromonas sp. (5.5%), Alcaligens faecalis (15%), Penicillium sp. (42%), Aspergillus sp. (20%) and Rhodotorula sp. (5.5%). This finding indicates substantial presence of microbial contaminants in retail chicken meat samples in North East India and dearth of proper sanitation in the market places.
