Multiple Challenges

Salmonellosis is known to be one of important issues that affect poultry industry as well as it can affect human health. Recently, multiple challenges are facing the use of natural antibacterial compounds, such as herbal extracts to overcome the massive increase in bacterial antibiotic resistance. Different Salmonella serotypes were recovered throughout examination of diarrheic poultry. These strains showed multidrug resistance by disc diffusion methods also, the resistance genes qnrS and aac (6′)-Ib-cr were detected in S. Enteritidis and S.Typhimurium which isolated from broiler's organs and muscles. The methanolic extracts of five plants (Alhagi maurorum, Conyza dioscoridis, Coriander sativum, Caracuma longa and Cuminum cyminum) were tested for their antibacterial activity against different isolated Salmonella serotypes using minimum inhibitory concentrations (MIC). Conyza dioscoridis was the most effective extract retarding microbial growth of Salmonella Enteritidis, while other plant extracts showed variable antimicrobial activity. These results are promising in the way of replacing the antibiotic therapy with natural substances to overcome the multidrug resistance.

The Ideal

Background: Garlic (Allium sativum) possesses health enhancing abilities due to the presence various phytoceutics moities. The current research was deigned to explore the phytochemicals and antioxidant capacity of Pakistani garlic. Methods: Garlic extracts were obtained using methanol, hexane and ethyl acetate at different time intervals (35, 50 and 65 min) followed by their polyphenols and flavonoid content determination. Afterwards, the antioxidant potential was also determined. Results: The outcomes revealed that the methanolic extracts obtained at 50 min extraction time showed maximum total phenolics as 60.38±0.23 mg GAE/100g and flavonoids as 58.45±1.24 mg/100g. Similarly, the highest DPPH activity (61.59±1.58%) and β-carotene and linoleic acid potential (64.96±1.72%) were also observed for methanolic extract. Conclusion: Inferences were made that Pakistani garlic contains myriad of phenolics and flavonoids but the extraction of these components depends upon the solvent/time combination. In this study, methanol proved to be the ideal solvent for the maximum extraction of phytochemicals from garlic.
