It is possible to induce chloramphenicol-resistance in Salmonella paratyphi B in vitro and to isolate mutants with different levels of resistance by different techniques. The resistance is invariably accompanied by definite changes in the morphological, cultural and biochemical properties. The degree of resistance and the conditions of isolation seem to influence the biological properties of the mutants. The higher the level of resistance, the greater will be the diversion from the normal.
在体外可诱导副伤寒乙杆菌产生氯霉素抗性，并通过不同技术分离出具有不同抗性水平的突变体。这种抗性总是伴随着形态、培养和生化特性的明确变化。抗性程度和分离条件似乎会影响突变体的生物学特性。抗性水平越高，与正常情况的差异就越大。
