Abstract

A study was conducted to find the effect of magnesium, calcium, manganese and zinc ions on the infection of Psudomonas aeruginosa strain 1C by RNA bacteriophage 7s. When an 18 hour progeny experiment was performed, it was found that magnesium, calcium and manganese had different effects on bacteriophage production and was dependent on the bacterial growth conditions. RNA bacteriophage 7s progeny production was significantly enhanced by the addition of magnesium to cultures of Psudomonas aeruginosa 1C grown in a magnesium deficient medium. Under these environmental conditions there was a slight increase in progeny in the presence of calcium. When Psudomonas aeruginosa 1c was grown in a complete medium, the infection of cells by bacteriophage 7s was enhanced by magnesium and calcium but not manganese or zinc, as demonstrated by the One Step Growth Curve.
