Patterns of virulence genes of Salmonella isolates obtained from poultry farms and cases of gastroenteritis in humans.

^∗ For PCR-based patterns, black area represents a positive result and white area represents negative result for the presence of a virulence gene. Virulence-related function is a Fimbriae gene function; b is type three secretion system gene function, b1 structure, b2 is effector protein, b3 is regulatory protein; c is survival inside cells gene function; d is plasmid gene function, e is iron metabolism gene function, and f is toxins gene function.
