In the present study, different metabolic compounds were extracted from C. procera using 75% methanol. The extract of C. procera was assessed against different bacteria of the SGB family by estimating the zone of inhibition. Moreover, minimal inhibitory concentration (MIC) of different concentrations e.g., 0.001, 0.01, 0.1, 1.0 and 10 mg/mL were determined through zone of inhibition. Gas chromatography mass spectrometry (GC-MS) analysis of plant extract revealed 24 compounds. The most important compounds of the GC-MS array were including undecane, terephthalic acid, Cyclohexane, dimethyl-propane-thiosulfinate, Fluorobenzoic acid Octadecenoic acid and others. The antibacterial activities of the plant extracts were might be because of their compound which had been reported previously as well as an antimicrobial compound.

They were screened for both HCV antibodies and HBsAg. The screening method used during the study was immunochromatographic technique (ICT), which showed that about 19.8% of the drivers were found to be HBsAg positive, while 5.5% were HCV positive. Also, 5.4% of the conductors were found to be HBsAg positive and 4.05% were HCV positive. This study revealed that chances of HCV and Hepatitis B is high in unmarried drivers and conductor as compared to married one.
