A Study design of the animal tests; dpc: days post challenge; hpc: hours post challenge; B A line chart showing changes of body weight of mice challenged with Salmonella Typhimurium 1344 by gavage and received a treatment of PBS by gavage (blue line); mice challenged with Salmonella Typhimurium 1344 by gavage and received a treatment of ph 2–2 by gavage (purple line); mice received an administration of PBS (green line) and/or ph 2–2 by gavage (orange line); Data represents mean ± SD. ns: No significance; C Mortality of mice challenged with Salmonella Typhimurium 1344 by gavage and received a treatment of PBS by gavage (blue line); mice challenged with Salmonella Typhimurium 1344 by gavage and received a treatment of ph 2–2 by gavage (purple line); mice received an administration of PBS (green line) and/or ph 2–2 by gavage (orange line); D Mortality of mice challenged with Salmonella Typhimurium 1344 through intraperitoneal injection and received a treatment of PBS through intraperitoneal injection (blue line); mice challenged with Salmonella Typhimurium 1344 through intraperitoneal injection and received a treatment of ph 2–2 through intraperitoneal injection (purple line); mice received an administration of PBS (green line) and/or ph 2–2 through intraperitoneal injection (orange line)
