Abstract: | Three variations of the amoxycillin-based triple therapy (amoxycillin, metronidazole and bismuth) were administered in the diet, by oral gavage or in the diet in conjunction with cross-fostering on to Helicobacter-free foster mothers to mice naturally infected with H. hepaticus and/or H. bilis. The presence of Helicobacter species was determined by polymerase chain reaction (PCR) analysis of faecal pellets. Helicobacter infection was eliminated in 50% of strains of mice treated by oral gavage; 57% of strains of mice treated by medicated diet alone and 100% of strains of mice treated with the medicated diet in conjunction with cross-fostering on to Helicobacter-free foster mothers. Eight strains of mice were successfully treated for Helicobacter infection over a two-year period. The mouse colony has been maintained Helicobacter free, as determined by PCR analysis and has remained off treatment from December 2002 to March 2005. |
