Antibiogram of 84 strains of Bacillus cereus, 26 strains of Clostridium perfringens, four strains of Staphylococcus aureus, 51 strains of Enterobacteriaceae, two strains of each of Salmonella and Shigella; isolated from spices, were studied against 20 different antibiotics that are commonly used against foodborne diseases, mainly gastroenteritis. All the tested strains of B. cereus, Cl. perfringens, Staph. aureus, Escherichia coli, Salmonella and Shigella were found resistant to at least 3, 4, 7, 6, 10 and 9 antibiotics, respectively. In brain-heart infusion broth supplemented with glucose, the D 1 0 0 ^ o C -values for B. cereus were 3.5-5.9min, and the z-values were 17-18 o C. The D 1 0 0 ^ o C -values for Cl. perfringens in fluid thioglycolate medium were higher (10.0-19.8min) than those of B. cereus. The minimum inhibitory concentrations (MICs) of sodium chloride were 45-80mgml - 1 . While the MIC of benzoic acid for Cl. perfringens, tested on perfringens agar (pH 7.3) plates by incubating anaerobially at 35 o C for 24h, was 1.9-2.2mgml - 1 , for others, tested on nutrient agar (pH 6.8) plates by incubating at 35 o C for 18h in static aerobic condition, it was much less. Similarly, the MIC of sorbic acid for all the tested isolates, excepting Cl. perfringens, was 0.6-1.1mgml - 1 . Of the eight isolates of Cl. perfringens, only three were inhibited at 2.0mg sorbic acidml - 1 , while others were resistant. Sixty percent and 75% of the respective strains of B. cereus and Cl. perfringens were resistant to 5000IU Nisaplinml - 1 , whereas the MIC values of Staph. aureus were between 3000 and 5000IUml - 1 . While studying combined effect of selected hurdles on the growth of enterotoxigenic Cl. perfringens 16-C2, the judicious combination considered was low acid (pH 6.0), 30mg sodium chlorideml - 1 and 1.25mg benzoic acidml - 1 .
