New Publications from Dr. Anup Kollanoor Johny

Two recent works were published from Dr. Johny’s lab in October – a peer-reviewed research article in the Poultry Science Journal, and a book chapter in an Academic Press publication. Dr. Johny and his group research on developing ‘Alternatives to Antibiotics’ (A2A) interventions against major foodborne bacteria that cause enteric illness in humans. Since poultry (broilers, layers, and turkeys) is a common host for pathogenic bacteria such as Salmonella, his group uses poultry in their challenge – intervention – response (CIR) studies to determine the efficacy of antibacterial interventions.

In the Poultry Science research article, Divek Nair (doctoral student of Dr. Johny) and Dr. Johny reports the potential of a probiotic bacterium of dairy origin, Propionibacterium, to kill Salmonella Heidelberg, one of the most invasive Salmonella serotypes in humans. This Salmonella caused a major nationwide outbreak in the USA a few years ago, where around 200 people contracted a severe illness. Ground turkey was the poultry product associated with the outbreak. Divek and Dr. Johny used different screening methods to determine the potential of Propionibacterium to kill the Salmonella. Please read the full article here ( Dr. Johny’s group has validated the studies in turkey poults, the report of which is currently under preparation.  

In the book chapter, Dr. Johny presents his research work on phytobiotics (plant-derived compounds) as another A2A intervention against Salmonella in poultry. He presents a strong case for phytobiotic nutrition in layer chickens to reduce Salmonella contamination of shelled eggs. Salmonella can get into the inside of eggs when the eggs are formed in the layer’s reproductive tract. Dr. Johny presents a comprehensive review of the use of phytobiotics in poultry, their current uses and prospects in animal nutrition, especially in the post-antibiotic era. He also discusses the problems associated with the commercialization of phytobiotics from his research experience and from other researchers who work in the area of phytobiotic nutrition.
