Characterization of Clostridium perfringens field isolates, implicated in necrotic entritis outbreaks on private broiler farms in Cairo, by multiplex PCR

During the winter of 2006, outbreaks of severe entritis affected many broiler farms in the AL-Fayoum governorate, south of Cairo, Egypt. To identify the causative agent(s), bacterial isolates (14) from the diseased chickens were characterized phenotypically and biochemically. All isolates exhibited characteristics of Clostridium perfringens. Subsequently, molecular typing of the bacterial isolates was performed by...

Retrospective study on the antibiotic resistant pattern of Salmonella typhi from some clinical samples

Due to reported cases of antimicrobial resistance by many pathogenic bacteria against many antibiotics worldwide, and the sparse nature of antimicrobial resistance data, a retrospective study was carried out on 744 isolates of Salmonella typhi obtained from 974 samples from four different hospitals in Yola, Adamawa State, Nigeria between 2001-2004 to determine the resistance pattern of S. typhi to...

Studies on the antibacterial activity of root extracts of Carica papaya L.

The bioactive compounds of root extracts of Carica papaya L. were extracted, using water and organic solvents, and were investigated for antibacterial activity against some pathogenic bacteria using the cup plate agar diffusion method. The aqueous extracts did not show significant activity, but the organic extracts had significant activity with the methanol extracts demonstrating the highest activity against...
