Antibiotics continue to be used as growth promoters in the poultry industry. Honeybee (Apis melifera) venom (HBV) possesses a number of beneficial biological activities, particularly for regulating the immune system. The aim of the present study was to evaluate the immunoprophylactic effects of HBV against Salmonella Gallinarum in broiler chicks as an initial step towards developing eco-friendl...
Salmonella causes an estimated 1.3 million human foodborne illnesses and more than 500 deaths each year in the United States, representing an annual estimated cost to the economy of approximately $2.4 billion. Salmonella enterica comprises more than 2,500 serotypes. With this genetic and environmental diversity, serotypes are adapted to live in a variety of hosts, which may or may not manifest ...
Salmonella enterica is an animal and zoonotic pathogen of worldwide importance and may be classified into serovars differing in virulence and host range. We sequenced and annotated the genomes of serovar Typhimurium, Choleraesuis, Dublin, and Gallinarum strains of defined virulence in each of three food-producing animal hosts. This provides valuable measures of intraserovar diversity and opport...
Facile laboratory tools are needed to augment identification in contamination events to trace the contamination back to the source (traceback) of Salmonella enterica subsp. enterica serovar Enteritidis (S. Enteritidis). Understanding the evolution and diversity within and among outbreak strains is the first step towards this goal. To this end, we collected 106 new S. Enteriditis isolates within...
Screening of a new strain of Streptomyces collinus, Lindenbein, A 19006, against Salmonella gallinarum led to the isolation of a new antibiotic. Examination of physical data and identification of hydrolysis products permitted the identification of this new metabolite as fumarylcarboxyamido-L-2,3-diaminopropionyl-L-alanine (I). The Gram-negative activity of the new antibiotic is inhibited by D-g...
