Gıda ve çevresel kaynaklarda Salmonella'nın hızlı, güvenilir hassas tespiti, halk sağlığını korumak için çok önemlidir. LAMP yöntemi özel cihazlara deneyimli personele ihtiyaç duymaksızın uygulanabilecek bir yöntem olduğu son yıllarda sıklıkla tercih edilmektedir. LAMP’ın, mikroakışkan cihazlarla kombine edilmesi sınırlı kaynakların durumlarda, hızlı tanı testleri alternatifdir. Salmonella spp....

The aims of this study were to isolation of Salmonella from poultry farms of Shiraz province of Iran and determination of their susceptibility against common antibiotics. One hundred and ninety two samples were harvested from intestine and liver of chickens and were aseptically cultured in enrichment and selective media. Out of 192 samples, 30 Salmonella were isolated. Four different serogroups...

Salmonella enterica subspecies enterica serovar Gallinarum biovar Gallinarum is the causative agent of fowl typhoid in chickens, outbreaks of which have devastated poultry populations in Korea since 1992. In order to identify genetic differences among S. Gallinarum isolates, bacteria were examined using the random amplified polymorphic DNA (RAPD) method. Of 13 arbitrary primers screened initial...

The F-wave is a result of the backfire of α-motoneurons following an antidromic inva‐ sion of propagated impulses across the axon hillock (Kimura, 1974). Its occurrence reflects excitability changes in the spinal motor neurons, as reported in patients with spasticity (Odusote & Eisen, 1979) and in healthy subjects with isometric contraction (Suzuki, Fujiwara & Takeda, 1993). In our previous stu...

A rapid and specific PCR assay for the simultaneous detection of Listeria monocytogenes, Escherichia coli O157:H7, Bacillus cereus, Salmonella spp., and Staphylococcus aureus in foods was developed to reduce the detection time and to increase sensitivity. Multiplex PCR developed in this study produced only actA, fliC, hbl, invA, ileS amplicons, but did not produce any non-specific amplicon. The...

We have developed a colorimetric biosensor using a dual platform of gold nanoparticles and graphene oxide sheets for the detection of Salmonella enterica. The presence of the invA gene in S. enterica causes a change in color of the biosensor from its original pinkish-red to a light purplish solution. This occurs through the aggregation of the primary gold nanoparticles-conjugated DNA probe onto...
