Virulence Factors Variation Among Bordetella Pertussis Isolates in Iran

Pertussis is still endemic and the recently resurgence of the disease caused by Bordetella pertussis has been shown in many countries. The polymorphism of the virulence genes of B. pertussis and lack of any information about the allelic variation between the Iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxS1, prn, fim3 and cya to understand the diffe...

The augmented histamine test with special reference to achlorhydria.

The Kay augmented histamine test has been used in a special study of 30 patients with pernicious anaemia and 136 other subjects suspected of having achlorhydria. The findings have been correlated with uropepsinogen excretion, serum levels of vitamin B(12), and gastric biopsy. The definition of achlorhydria is specially considered.
