Is it possible to presume about which Salomonella species present in the sample without using molecular tools like PCR? Just from biochemical tests?
If I plan to do PCR for confirming species, how do I decide which primers I need to use? Studying literature for prevalent species information? Or there is any practical methodology?
Here are some techniques, optical and mechanical.

Dear Ruhshan Ahmed Abir
You can use differents approaches:
- Novel culture techniques as: immunomagnetic separation, EIA- and ELISA-based assays incorporating fluorescent or colorimetric detection, simple lateral flow assays incorporating immunochromatographic technology
-The ISO-6579 standard (ref. 1) which recommends using the TSI agar, Urea agar (Christensen), L-lysine decarboxylase, β-galactosidase (ONPG), Voges Proskauer and Indole tests in this order.
-The LOUIS test is a screening protocol for Salmonella and Shigella that uses rapid enzyme test.
Please find another information in the following manuscript: Rapid and Economical Method for Biochemical Screening of Stool Isolates for Salmonella and Shigella Species. J Clin Microbiol. 2004 Oct; 42(10): 4821–4823.
Hoping to be helpful
