S. typhimurium

[IVANO at DINCO.INCQS.FIOCRUZ.BR]

Dear microbiologists,

I need a strain of Salmonella typhimurium nalidixic acid resistent, to use as
control on food Quality Control assays. The strain number stated in literature
is Lfd TM 98, but it has been difficult to find in collections.
Does anybody knows where I find it?

Thanks in advance.
