A new antibiotic resistance gene in Salmonella isolated from broiler chickens

Dr. Moussa Diarra’s laboratory previously described Salmonella enterica serovar Heidelberg isolates harboring a chromosomal gene cluster similar to the glutathione S-transferase gene, a putative fosA gene conferring resistance to fosfomycin. Here, we show that this new gene, named fosA7, confers resistance to fosfomycin. The introduction of fosA7 into the fosfomycin-susceptible Salmonella enterica serovar Enteritidis resulted […]

Cranberry Extracts Could Replace Antibiotics For Broilers

  Broiler chicken producers may be using cranberry extracts to replace antibiotics in young birds. Agriculture and Agri-Food Canada research suggest the extracts could cut mortality by 50 per cent in the early life of broilers. Doctor Moussa Dairra points out cranberries have various human health benefits because of their high antioxidant compounds and immune-boosting […]
