Pathogenic Escherichia coli are found in the contaminated raw meat. Contamination is common in Pakistan due to unhygienic condition. The present work was based on the entomopathogenic effect of E.coli against Tribolium castaneum. The cultured sample of E.coli O157 isolated from raw meat was used in this study. Microbial screening of pathogenic bacteria was done by using different media such as TSB, MacConkey and Novobiocin. Rearing of Tribolium castaneum was done in the Laboratory of LCWU. Bioassay technique was applied for the detection of effect of E.coli against the Tribolium castaneum....

Pathogenic Escherichia coli is found in the contaminated raw meat, raw milk, raw vegetables, contaminated water. The present work was based on the entomopathogenic effect of E.coli against stored grain pest Tribolium castaneum. Microbial screening of pathogenic bacteria was done by using different media such as TSB media, MacConkey media and Novobiocin media. Rearing of Tribolium castaneum was done and different stages of Tribolium castaneum such as larvae, pupae and adult were observed. Bioassay technique was applied for the detection of effect of E.coli against the Tribolium castaneum. The...

We performed a retrospective study between December 2010 and May 2011 on all retinitis pigmentosa (RP) cases seen from Okara during ophthalmological consultation at Lyton Rahmatullah Benevolent trust (LRBT) hospital from August 2008 to January 2011. The aim of this study was to determine the preponderance of low vision and blindness in retinitis pigmentosa in patients of Okara. The techniques used for the diagnosis of retinitis pigmentosa were an examination of ocular fundus using a biomicroscope (fundoscopy), far visual acuity and visual field. Indeed, a drop in visual acuity and blindness...
