Pandey, Mritunjay, Khan, Asis, Das, Suresh C., Sarkar, Bhaswati, Kahali, Soumen, Chakraborty, Subhra, ...

Among Escherichia coli strains isolated from stool specimens from patients with acute diarrhea, 1.4% were found to harbor cdtB by use of enrichment cytolethal distending toxin (CDT) PCR. These...

Multiplex PCR Assay for Rapid Detection and Genotyping of Helicobacter pylori Directly from Biopsy Specimens

Chattopadhyay, Santanu, Patra, Rajashree, Ramamurthy, T., Chowdhury, Abhijit, Santra, Amal, Dhali, G. K., ...

Antimicrobial Susceptibility of Helicobacter pylori Strains Isolated in Bangladesh

Nahar, Shamsun, Mukhopadhyay, Asish K., Khan, Rasel, Ahmad, Mian Mashhud, Datta, Simanti, Chattopadhyay, Santanu, ...

Antimicrobial susceptibility of 120 Helicobacter pylori isolates to metronidazole, tetracycline, clarithromycin, and amoxicillin was determined, and 77.5, 15, 10, and 6.6% of the isolates,...

Inhibition of STAT 1 Phosphorylation by Human Parainfluenza Virus Type 3 C Protein

Malur, Achut G., Chattopadhyay, Santanu, Maitra, Ratan K., Banerjee, Amiya K.

The P mRNA of the viruses belonging to the subfamily Paramyxovirinae possesses a unique property of giving rise to several accessory proteins by a process that involves the utilization of overlapping...

Mitogen-activated protein kinases and nuclear factor-kappaB regulate Helicobacter pylori-mediated interleukin-8 release from macrophages.

Bhattacharyya, Asima, Pathak, Shresh, Datta, Simanti, Chattopadhyay, Santanu, Basu, Joyoti, Kundu, Manikuntala

Gastric infection, as well as inflammation, caused by Helicobacter pylori, activates the production of cytokines and chemokines by mononuclear cells; interleukin-8 (IL-8) is one of the major...
