Identification Of Major Salmonella Serovars By

Polymerase chain reaction (PCR) protocols have been developed to detect major Salmonella serovars, such as Typhi, Paratyphi A, Typhimurium, and Enteritidis. However, these methods are not yet widely used and are impractical in the areas where such salmonella infections are common. Detection of Salmonella species and major Salmonella serovars by PCR has been reported by many researchers, as shown in Table 3. S. Typhi and Paratyphi A are important in clinical laboratories, and their direct detection in blood or stool has been intensively studied.

Diagnosis of typhoid and paratyphoid fevers is performed on blood or stool by using culture methods and requires at least 4 or 5 working days. A rapid, alternative diagnostic method is required for the diagnosis of typhoid fever and paratyphoid fever. Targets for detection of S. Typhi by PCR include the fliC-d gene[3] Vi capsular antigen gene,[4] and 16S-23S rRNA spacer region gene

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
