Salmonella weltevreden has been found to be one of the commonest Salmonella serotypes isolated from diverse sources in India and has also been isolated in a number of other countries. A phage typing scheme was developed for this serotype using a set of six typing phages. These phages had been selected out of 146 phage strains isolated and purified from stool samples of man, laboratory animals and other animals, sewage and surface water sources, and the lytic mutants of temperate phages form S. weltevreden. The phage typing scheme was applied systematically to type the 946 strains from India isolated during 1958-1974 and 148 strains originating from Australia, Burma, England, Gan Island, Holland, Hong Kong, Malaysia, New Zealand, Papua New Guinea, The Philippines, Thailand, The United States and Vietnam during 1953-1971. The scheme was particularly studied to evaluate its utility in mapping the epidemiologically related strains from various sources. The S. weltevreden strains could be classified into ten phage types. Phage types 2 and 7 were found exclusively amongst Indian strains, type 6 from Vietnam and type 8 from Burma, Thailand and Vietnam. Phage types were found to be stable and consistent with the independent epidemiological data available.
韦尔泰夫登沙门氏菌已被发现是从印度不同来源分离出的最常见的沙门氏菌血清型之一，并且在其他一些国家也有分离到。使用一组六种分型噬菌体为该血清型制定了噬菌体分型方案。这些噬菌体是从146株从人、实验动物和其他动物的粪便样本、污水和地表水源中分离和纯化的噬菌体菌株，以及韦尔泰夫登沙门氏菌的温和噬菌体的裂解突变体中挑选出来的。该噬菌体分型方案被系统地应用于对1958 - 1974年期间从印度分离的946株菌株以及1953 - 1971年期间来自澳大利亚、缅甸、英国、甘岛、荷兰、香港、马来西亚、新西兰、巴布亚新几内亚、菲律宾、泰国、美国和越南的148株菌株进行分型。对该方案进行了特别研究，以评估其在绘制来自各种来源的流行病学相关菌株图谱方面的效用。韦尔泰夫登沙门氏菌菌株可分为十种噬菌体类型。噬菌体类型2和7仅在印度菌株中发现，类型6来自越南，类型8来自缅甸、泰国和越南。发现噬菌体类型是稳定的，并且与现有的独立流行病学数据一致。
