Statistical Analysis of Air-Borne Bacteria Isolated from Different Sites of Karachi University

Air-borne bacteria were isolated from different sites of Karachi University. These isolates were purified and checked against different antibiotics like ampicillin, kanamycin, tetracycline and streptomycin and against metal salts like Copper sulphate, Cadmium chloride, Cobalt chloride, Nickel sulphate and Mercury chloride. Most of these isolates were found to be highly resistant to the tested metals and antibiotics. More samples are being collected to have a proper idea of environmental status of the Karachi metropolis. These studies will provide an idea of environmental conditions and can be used for its monitoring. Statistical analysis has showed that there was no difference in the three environments. Correlation was also observed for metal and antibiotic resistance in the organisms of experimental area.
